IDE\Structure Pane
Description:
Steps:
[QC Short Description]
Strcuture View (formerly Object TreeView) doesn't automatically scroll when in Drag&Drop
1. Create a new application 2. Drop quite a few buttons etc. on the form and a PageControl. 3. Open the Object
TreeView (Alt+Shift+F11) 4. Resize the Object TreeView window so that not all nodes are visible and the
scrollbars appear 5. Now try to drag one of the buttons TreeNodes to the edges of the TreeView exp: TreeView
should automatically scroll act: Nothing
[QC Description]
When designing complex forms the content of Structure View doesn't fit on the screen.
If you then try to move components in the Structure TreeView by Drag&Drop you can't drop it onto a TreeView
node which is currently not visible because the TreeView doesn't scroll
when you're pointing your mouse near the edges of the TreeView.
That way Object TreeView loses it's most important feature (IMO) !

IDE\Code Editor\Keymapping
Description:
Steps:
Tab key should indent block
[QC Description]
The tab key should indent a block of text when it is highlighted. This is the behaviour of most other IDEs and
makes more sense than the current key combination.
Shift+tab should unindent a block of text when it is highlighted.
This suggestion costs nothing to implement, has no negatives, makes life easier for people changing from VB, is
intuitive for new users, and makes it easier for everyone who has ever had to indent text.
There is no need to remove the current functionality of tab when no block is highlighted. And there is no need to
remove the other keystrokes which indent blocks of text.

IDE\Search\Find in Files
Description:
Steps:
Allow "find in files" in properties on forms/datamodels/frames (DFMs)
[QC Description]
When finding in files only the source code is searched. There is no such function for searching in all forms / data
models within a project / directory etc.
Example:
Your customer asks you to change all texts / labels / ... from Automobile to Vehicle. You know this word is
present is source code, on many forms in captions, hints etc.
Do a "Find in files" on Automobile with the (Associated files checkbox enabled or something like that). When you
select the Automobiles found on DFMs it popups the form, selects the correct component/control, popups the
Object Inspector and selects the correct property.

VCL\Additional Controls\TCheckListBox
Description:
Steps:
(This report "migrated" from QC 2267 for D6)
It would be really useful to have the following methods in TCheckListBox:
CheckAll; -> set all items to Checked
UncheckAll;-> set all items to Unchecked
It might be nice to include a default (const bool=True) parameter to specify whether also the Grayed items
should be influenced by these sweep-all methods.
(PS why is there no QC "Area" for VCL TCheckListBox in D.NET?)

Database\TParams
Description:
Steps:
ParseSQL alters function parameter by value
Open the attachement and click the button on the mainform.
It enters an event handler which will initialize some components reproduce the bug and show a workaround.
[QC Description]
TParams.ParseSql is declared as:
with SqlClientDataSet1 do
begin
CommandText := 'select * from employee where emp_no=:emp_no';
Params.ParseSQL(CommandText, True); { <-- BUG ALTERS THE COMMANDTEXT VALUE }
Params.ParamValues['emp_no'] := 100;
Open; { <-- EXCEPTION APPEARS HERE }
end;
function ParseSQL(SQL: String; DoCreate: Boolean): String;
But the implementation behaves like the SQL is passed as a parameter by reference. It used a PChar typecast
on the SQL parameter and works on the characters inside this buffer. Therefor it behaves as a parameter by
reference:
ParseSql(var SQL: string; DoCreate: boolean);
ParseSql's implementation should not affect the original SQL string parameter.

[QC Description]
Since there is no way to tell if an blank DBEdit is to be stored as NULL or an Empty string an extra property to
TIBStringField (EmptyAsNull) should be added so the developer can override the default behavior of storing
NULL. The default should be true to keep the long standing behavior intact (this behavior matches most
TDataset descendants).

Database\TParams
Description:
Steps:
ParseSQL incorrectly interprets quotes in literal strings
With ParamCheck = TRUE, set SQL.Text on a query similar to the following (Oracle is the RDBMS in this
example): SELECT SYSDATE FROM DUAL WHERE USER IN ( 'LPs are 12" in diameter', 'My TV is 16:9
ratio' ) The ParseSQL implementation incorrectly identifies a parameter with a name of "9". This could be
particularly tricky to identify as a problem, considering that this, only slightly different, query works as expected:
SELECT SYSDATE FROM DUAL WHERE USER IN ( 'LPs are 12" in diameter', 'CDs are 5" in diameter', 'My
TV is 16:9 ratio' )
[QC Description]
When parsing an SQL statement that contains strings literals, the ParseSQL implementation does not properly
interpret quote characters embedded within those literals.
A double-quote char (") encountered within a string literal (enclosed by a pair of ') is interpreted as the end of the
string literal.
In most cases this is a silent failure, but if you also have string literals in the SQL that contain colons, then under
the right conditions that colon is treated as a parameter identifier and not part of a literal.
We found this because we had a query that built a "WHERE COLUMN IN ( <string literal list>)", where the
literals included some entries with length information (" denoting inches) and ratios (e.g, 1:500).
NB - I have yet to check Delphi7 as I don't currently have access to my D7 installation, to see whether the
implementation of ParseSQL has been altered to address this area.

ActiveX\Framework\DAX\Container Support (TOleControl)
Description:
Steps:
I have created a simple ActiveX control which is a descendant of the TActiveXControl. (I picked TMemo for the
VCL Class Name in the ActiveX Control wizard).
procedure TActiveXControl.Initialize;
begin
inherited Initialize;
FConnectionPoints := TConnectionPoints.Create(Self);
FControlFactory := Factory as TActiveXControlFactory;
if FControlFactory.EventTypeInfo <> nil then
FConnectionPoints.CreateConnectionPoint(FControlFactory.EventIID,
ckSingle, EventConnect);
FPropertySinks := FConnectionPoints.CreateConnectionPoint(IPropertyNotifySink,
ckMulti, nil);
FControl := FControlFactory.WinControlClass.CreateParented(ParkingWindow);
if csReflector in FControl.ControlStyle then
FWinControl := TReflectorWindow.Create(ParkingWindow, FControl) else
FWinControl := FControl;
FControlWndProc := FControl.WindowProc;
FControl.WindowProc := WndProc;
InitializeControl;
end;
When I dynamically instantiate this control in a client program and Free it, it seems to have a memory leak. I
have a client program which basically creates and frees the control in a loop and you can watch the memory
leak.
I have attached the ActiveX and the client program source code.
An interesting point to note is that if I replace the Delphi 7 version of Axctrls.pas unit with the one in Delphi 6
version, the problem seems to go away!
There are a few differences between these files… but perhaps the most significant is the code as noted below.
destructor TActiveXControl.Destroy;
begin
if Assigned(FControlWndProc) then FControl.WindowProc := FControlWndProc;
FControl.Free;
if FWinControl <> FControl then FWinControl.Free;
FConnectionPoints.Free;
inherited Destroy;
end;
Delphi 7.x (Axctrls.pas)
Noted: The addition of code that allocates an instance of the class ToleLinkStub and then manually adjusts the
interface pointer reference count (why is this done?)
procedure TActiveXControl.Initialize;
begin
inherited Initialize;
FConnectionPoints := TConnectionPoints.Create(Self);
FOleLinkStub := TOleLinkStub.Create(nil);
FOleLinkStub._AddRef;
FControlFactory := Factory as TActiveXControlFactory;
if FControlFactory.EventTypeInfo <> nil then
FConnectionPoints.CreateConnectionPoint(FControlFactory.EventIID,
ckSingle, EventConnect);
FPropertySinks := FConnectionPoints.CreateConnectionPoint(IPropertyNotifySink,
ckMulti, nil);
FControl := FControlFactory.WinControlClass.CreateParented(ParkingWindow);
if csReflector in FControl.ControlStyle then

VCL\Printing
Description:
Steps:
TPrinter fails in Service Applications on W2K
Create new service application. Add Printers to the uses clause In the service attempt to read the value of
Printer.PrinterIndex Watch the exception happen via debugger (or with a try/except block and a dialog message
(requires the service be set to interact with the desktop)) Note: I had the service set to interact with the desktop,
though it still happens when it is not set this way. I did not try running the service in a specific account, only the
local system account.
[QC Description]
When a service application uses the local system account on Windows 2000 the procedure
TPrinter.SetToDefaultPrinter fails to identify and set the default printer. The property Printers does contain the
complete list of printers. Because the TPrinter object fails to properly set the default printer most calls end up
with an exception, even attempting to set the default printer.
In the SetToDefaultPrinter procedure the following block of code is executed and the value of Device is a single
space.
else begin
GetProfileString('windows', 'device', '', DefaultPrinter,
SizeOf(DefaultPrinter) - 1);
Cur := DefaultPrinter;
Device := FetchStr(Cur);
{As a w2k service in local account Device is ' ' at this point}
It should also be noted that this is not the method Microsoft recommends for finding the default printer, though I
can't seem to find the link on MSDN where I was reading this.

Steps:

Compiler\Delphi\Language
Description:
Steps:
Allow multiple properties to be default within a single class
Allow the following syntax: type T1 = class private function GetA(Idx: Integer): string; function GetB(Idx: string):
Integer; procedure SetA(Idx: Integer; const Value: string); procedure SetB(Idx: string; const Value: Integer);
public property A[Idx: Integer]: string read GetA write SetA; default; property B[Idx: string]: Integer read GetB
write SetB; default; end;
[QC Description]
Currently, only a single default property is allowed within a single class. This default property can also be
considered an overloaded operator [] . Whenever the index datatypes differ, it can be allowed to add multiple
default properties.
Example:
Consider a 'list' class where objects need to be accessed on index in the array and on some key (for example a
string). You could use the following notation:
for i := 0 to 9 do DoSomethingInteresting(List[i]);
DoSomethingInteresting(List['John']);
I think this would allow Delphi to extend its easy to readability of Delphi source code, it does not introduce
ambiguity (just like overloaded methods) like default properties without indexers would.

Description:
Steps:
Update: DBGrid doesn't repaint itself correctly when scroll bars get are toggled from off, to on, to off. (This is
really seen in master detail apps... when a master record has 0 detail and another master record has serveral
detail records)
1. Compile and Run the attached test-case 2. Record 4 is active in the top grid; note that the bottom detail grid
needs a scrollbar to show all records 3. In the top grid activate the record with 5 in the first field 4. Go back to
the record 4 exp: Scrollbar in the bottom detail grid should be displayed as in step 2 act: Scollbar is hidden If
you repeat steps 3 and 4, notice how the grid scrollbar appears and dissappears. You can just about make out
the outline of the scrollbar on the right, including the thumb thingy shadow moving as you scroll!
TDBGrid vertical scrollbar dissappears
[QC Description]
When you have a master/detail record, and the detail is shown using a TDBGrid, then the vertical scrollbar
dissappear randomly, even if there are more records than will fit! You can see the right border outline of the
scrollbar though, including the thumb thingy moving. It's as if the grid has resized slightly over the scrollbar.
See attached test-case.

found.
As a result I'm regularly getting support requests, because people think my component collection is at fault.

Open Project menu item doesn't use the correct filter
[QC Description]
When you select Open Project from either the menu item or the toolbar, the filter used is wrong. By default the
filter used is the "Borland Developer Studio File" which incase you don't know, includes just about every file you
could ever hope to use in the IDE.
This is wrong. The reason I have done "Open Project" is so that I can open a PROJECT file. A PROJECT file for
Delphi 2005 and it should be either a bdsproj or bdsgroup (I like to live in the NOW not the past). Not all of the
legacy project file types. Once I've updated my project to Delphi 2005, I should not have to continually see these
files in a default filter. For one thing it's off putting seeing twice as many files lists as I expected.
Perhaps there needs to be a "Delphi 2005 Project File" filter that includes bdsproj and bdsgroup ONLY and it's
the default filter for the Open Project action.
If people want to upgrade a project to D2005, then let them select the Delphi Project or Delphi Package filters
(which should be combined into a Delphi Legacy Filter IMHO). After all - they are only ever going to do it once.

box just under the checkbox. This is a single-line text box containing a semicolon-delimited list (typically a very
long list) of package names. 6. Try to remove an item from this list. Note that the only way to do so is clicking
and typing, typically with a lot of scrolling left and right (because the list is usually wider than the text box). 7. In
the treeview, select the "Directories/Conditionals" page. 8. Note the similarity: this page has a large number of
combo boxes, most of which contain a (sometimes long) semicolon-delimited list. Also note the "..." buttons. 9.
Click the "..." button next to one of the combo boxes. A "Directories" dialog box appears, with the semicolondelimited list split out into multiple lines in a list box. Note the buttons for adding new items to the list, removing
items from the list, and replacing items. If the list of runtime packages had a "..." button, and that button brought
up a dialog similar to this "Directories" dialog, runtime packages would be a great deal easier to work with.
[QC Description]
In Project Options, the list of runtime packages is jammed into a single edit box.
Please add a way to make this list more easily editable. Something similar to the "..." buttons from
Directories/Conditionals (and the list-edit dialogs they bring up) would be an excellent way to accomplish this.

VCL\Win 32 Controls\TListView
Description:
Steps:
Basic bug in clear leads to huge execution time
1. Create empty VCL application. 2. Paste this procedure TForm1.FormCreate(Sender: TObject); var I : integer;
begin FListView := TListView.Create(Self); with FListView do begin Parent := self; Align := alLeft; ViewStyle :=
vsReport; Columns.Add.Width := 200; SortType := stNone; Items.BeginUpdate; for I := 1 to 10000 do AddItem
(IntToStr(I), nil); Items.EndUpdate; end; end; 3. Run 4. Close (while looking at the task manager CPU). Then
you can try the same using the attached comctrls unit (be sure to build with it).
[QC Description]
First the behavior: if you have a simple list with 10000 items, clearing takes a lot of time (populating takes also
time, but that's something else).
Clear is sending LVM_DELETEALLITEMS message, which triggers LVN_DELETEALLITEMS notification.
There are several basic problems with notifications:
- Item.Destroy sends LVM_DELETEITEM message even if it's coming from a notification. This means that
LVN_DELETEALLITEMS triggers one LVN_DELETEITEM also, which is totally unnecessary (there is some logic
to avoid double free) IF LVN_DELETEALLITEMS returns 1.
- LVN_DELETEALLITEMS does NOT set the return value to 1 (same in LVN_DELETEITEM)! Because of this
each list item must be deleted (in destroy) sending an explicit call.
Correcting these problems leads to an instant response for the clear call.

IDE\Search
Description:
Steps:
Remove modal search dialog and add a "Firefox Search Bar"
[QC Description]
Currently, the current file search feature of the IDE pops up a modal dialog box, which the user fills out, and
which then requires a click.
Since modal dialogs are rapidly going out of style, please institute a search functionality similar to that found in
the Firefox web browser.
Rather than pop up a modal dialog, the IDE should display at the bottom of the editor a small tool bar that allows
the user to type the search phrase into an edit box. Incremental search is done as the user types. If the user
types something that is not found in the file, then a small "not found" sound is played. The tool bar can have
common search choices such as "Match Case", "Find Next", "Find Previous", etc.
I've grown quite used to the Firefox Search model, and really like it. I think it would make a great addition to the
Delphi IDE.

Debugger\Evaluator ToolTips
Description:
Steps:
Eval Hover Hints Do Not Update As Easily as in D7
For example, File, New VCL Forms App Double click the form aand add this code Set a breakpoint on that
single line, run Move the mouse from Self to Caption, but the hint still shows the Self eval hint: procedure
TForm1.FormCreate(Sender: TObject); begin Self.Caption := 'Test'; end;
[QC Description]
While debugging, if I move the mouse from one identifier to the next, the previous eval hint doesn't always
disappear, so I have to click to make the hint move to the new identifier and show the new identifier's value.
Previously, I could just hover. See Steps.
The above may be a change in behavior because it thinks I might be moving
the mouse into the hint to expand something?
From Chris:
Yes, before expandable hints, the code would keep the hint visible as long as the mouse stayed in the bounding
rectangle of the editor token. Now, it uses a union of the editor token rect and the hint rect itself. So in most
cases it won't go away when simply moving the mouse horizontally to a different token on the same line
(depending on how wide the hint itself is).
There may be a way to be smarter about this. If you file a QC report for this, I'll investigate it.

Description:
Steps:
Using view unit (Ctrl+F12) always shows design form
Set IDE to non embedded classic undocked. Open up a project with several units that have design forms. Try
flipping between the units using Ctrl+F12. Notice that the IDE will always show the form, and not the source
view. So you have to press F12 once more. (Creates another problem, see QC 10661: Install all components
from JVCL and DevExpress, and then try this. Notice that it will take about 2-3 seconds for it to switch)
[QC Description]
Tested in non embedded, classic undocked.
Default behaviour is broken, as the designer now always show the design form of the unit when using Ctrl+F12
to view a new unit.
Default behaviour before was showing the source code, and is the most logical thing to have here since you
want to vew the unit, not the form. You have Shift+F12 (View form) for that.
Since viewing a form takes 2 seconds on a XP 3200 with 1G RAM (when JVCL and DevExpress is installed), a
bi effect is that switching units will take a long time. See QC 10661 for more info on this (speeded up a bit in
D2005 update 3). But still slow.
So please change it back to the standard behaviour, and view source instead of form. Or make it an option.

Steps:
I have the IDE set to echo command lines in the message window. When I tried to use this to capture a
command line for a delphi package I was surprised to find that the command line does not work - even after
extensive work on my part to try to "fix it up".
- i have a Output directory of "..\..\Bin" specified for my project. very obviously, the assembly also gets built into
said directory. however, when i turn on "Show CommandLine" i see "-ER:\RemObjects SDK
for .NET\Source\RemObjects.SDK.Delphi8\" which is my project folder.
Tried also with a simple delphi vcl forms app and had the same problem.
- the command line output lists an option of -C0 [That's a Zero], which dccil doesn't understand.
- the command line output also lists the .dpk as *last* item of the commandline, leading dccil to emit "project
$A-" not found. the project has to be the FIRST item on the command line
- it doesn't bother to prefix the $A+ etc compiler options with a "-"
- it doesn't bother to quote filenames and searchpaths that have spaces
in summary, i guess it would have been easier to list what parts the command line output got *right*, and it's
hard to hold back saying this is just completely useless.

IDE\Packages\Package Manager
Description:
Steps:
Adding a unit with a form to a package only registers the unit
Create a new package and save it. Create a form and save it. Remove form from package. Right-click on
package and click Add. Select the unit you previously removed. Check the project manager. The form branch is
not there and the package source doesn't have the form name associated to the unit.
[QC Description]
If you create a new package and create a form in the package, the Project Manager correctly displays a unit with
a form branch. If you remove the form and add the unit manually by any means (drag and drop, right-click->Add)
the unit is registered and does NOT have the form branch showing.
This affect StarTeam checkin and checkout and also affects form inheritance since the base class cannot be
found unless the form info is specified in the package source.
The package source after adding looks like this:
Unit1 in 'Unit1.pas';
when it should look like:
Unit1 in 'Unit1.pas' {Form1};
I have to manually edit the package source to correct it.

Using external editors for unsupported file types
[QC Description]
It would be great if files, added to project, but not supported by IDE editors, would be edited in their original
editors if you just double click them in Project Manager window.
For example, I have a folder Documents. There are some DOC and XLS files related to my project. For now if I
want to see their contents or edit them I have to open then from external editors (Word, Excel etc.) or find them
by file manager and activate.
If I double click them in Project Manager, Delphi tries to edit such files - opens them in hex editor. Instead of
such behaviour I propose to just raise such files with ShellExecute function.
That would:
1. save time when need to edit some info
2. help to collect all project-related files in project manager. (well not 'help' itself, but stimulate to do so)

responsive. This means that the toolbar buttons used to control the debug target application (such as pause) are
no longer clickable. Perhaps some kind of throttling, or some kind of buffering is necessary for
OutputDebugString output.
This is really severe because it means that the target delphi app (or C++Builder app, or perhaps even a dotNet
app) that outputs enough output via the win32 api OutputDebugString could make the whole IDE unstable.
If the target application keeps outputing lots of OutputDebugString output permanently, then the only way out of
the situation is to kill the IDE and the target Application exe. This causes major data loss.
This does NOT happen in Delphi 7. It appears to happen in Delphi 2005 and 2006. It may be infrequent for most
users, since most users don't have a lot of outputdebugstring messages, and are probably careful not to
generate a huge amount of it. but if you ever slip up and put a debug message somewhere where it gets hit 100
times a second, you can kiss your IDE goodbye.

Qualifiable enumeration constants
[QC Description]
Enumeration constants are always in unit scope, even if declared local to a class.
Due to this language "quirk" generations of Pascal programmers are in need to prefix nearly all those constants
with something in order to circumvent the likely naming conflict.
If there were a possibility to quilify the identifiers those problems were absent.
I propose something like the following:
type te=enum(a,b,c);
To access the constants you would write stuff like te.a.
For enum types generated by this new syntax I suggest that they must be qualified.
By the way: This opens the possibility to even create expandable enums like
type te_enhances=enum[te](d,e,f);

Make a routine to create many TThread's that finish up very quickly. Set them to FreeOnTerminate and use the
TThread.Resume. Set FastMM to use FullDebugMode, and it will detect modified memory after free.
[QC Description]
When using TThread in suspended state, and FreeOnTerminate, TThread.Resume miss threadsafe handling of
the thread.

var
SuspendCount: Integer;
begin
SuspendCount := ResumeThread(FHandle);
CheckThreadError(SuspendCount >= 0);
if SuspendCount = 1 then
FSuspended := False;
end;
The problem is, if there are many threads created and freed, the delay after ResumeThread(FHandle) could be
big enough for the thread to finish and free itself before the routine arrives at FSuspended := False.
This will cause TThread.Resume to set a value on the freed object, and in worst case corrupt memory on newly
allocated memory for some other structure.
This routine has to be made threadsafe, with interlocked states or using a critical section. One solution could be

2. When a project is loaded: Clicking the Components/Install Packages menu item brings up a dialog/window
'Project Options for ThisProject.exe' which is NOT resizable.
However obviously this is not the same dialog as when clicking Project/Options so the question arises why this
dialog is not resizable as the dialog/window under 1.
Not resizable dialogs which contain lists of variable length are a very bad design, because the user has to scroll
a lot to find the desired list item and he has no overview to the whole list.
Dialogs which are not resizable containing lists of variable length are a reminiscence to the old times of DOS
where such cumbersome user interfaces were a result of the restricted technology at that time.

RTL\Delphi\Pascal Strings
Description:
Steps:
Please complete the functionality of the UTF8String type
N/A - Feature request
[QC Description]
Delphi 2006 has rudimentary support for UTF-8 text through the UTF8String type. This report requests the
completion of the compiler and language support necessary to make this type fully functional and on par with the
AnsiString and WideString types.
Currently the type maps to a long string, which is great since that means it inherits some great features
(allocation/deallocation speed, reference counting, etc.). However, there are many areas in which support is
currently lacking:
1) Implicit type conversion: UTF8String is currently treated in exactly the same way as an AnsiString when doing
assignments to different types, so assigning a UTF8String to a WideString or Ansistring will cause data
corruption if the UTF8String contains code points outside the ASCII range (code points U+0 to U+7F).
2) Object Inspector support: UTF8Strings cannot be edited in the Object Inspector. Again, the UTF8String is
treated as an ordinary AnsiString, and thus code points outside the ASCII range are lost or corrupted.
3) Compiler support for UTF-8 string constants: The compiler does not support the assignment of Unicode text
constants to UTF8String variables. All code points outside the ASCII range are lost or corrupted when assigning
a Unicode text constant to a UTF8String variable. The compiler should implicitly convert the constant to UTF-8
during compilation.
4) Manual type conversion functions (Utf8ToUnicode and UnicodeToUTF8) only support the BMP (Basic
Multilingual Plane, plane 0. i.e. the first 64K code points): The RTL and IDE's Unicode support is still limited to
UCS-2, whereas Windows has moved on to UTF-16.
Full support of UTF-8 is a worthwhile companion to full support of UTF-16. UTF-8 is more storage space efficient
than UTF-16 when working with predominantly European languages. Backed by the long string type the
UTF8String type is also faster than the WideString type because it is not allocated on the (slow) Windows heap,
and it is also reference counted.

control) 5) Open the project 6) Close the project Step 6 fails because ......bdsproj.local is read-only. ---------Additional from QA -------------------- You must kill the IDE in order to close the project. You are unable to close
the project or start a new one because the files are not handled correctly.

There has been NG chatter (on & off) about this for the last 6 years, but apparently it was never entered in QC.
It would be great if we could set our own limit for the MRU Project list; 4 are just not enough.
I generally ping-pong between 6 - 7 different projects in any given month. Not too mention package builds.
I have one client who currently has 6 on going projects for different sections of their company.
If you can't let us set the limit, then I would suggest that 10 - 15 would be a respectable number.

Project Manager should scroll automatically if necessary when dragging file to new location
Open a project with a large number of files. Size the PM pane to not show all of the files in the project Scroll so
that the last file in the list is showing Grab the bottom file and try to drag to the top of the list - move it above the
top visible file - window does not scroll It is necessary to drop the file near the top of the list, scroll the list and
then grab and drag the file again to reach the top of the list.
[QC Description]
The Project Manager pane allows files to be dragged to new locations with the mouse, but if the desired location
is not visible in the pane, it will not scroll to show the location.
Please add auto-scrolling during dragging as is done in Windows Explorer.

This is very similar to QC 584 and very easy to implement since this is automatically supported by

IDE may select the wrong file when performing a ctrl + left-click on a filename in the editor
Steps: 1) Extract the attached files into a folder, preserving the folder structure 2) Start the BDS (Win32) 3) File>Open and select Folder1\Project1.dpr 4) File->Open and select Folder2\Unit1.pas 5) Click on the
"Project1.dpr" tab in the editor 6) Hold down Ctrl and left-click (or right-click->"Open File At Cursor") on "Unit1"
on the line "Unit1 in 'Unit1.pas';" in the editor. Up to this point everything is as expected. In step 6 the editor
opens up the correct Unit1.pas, ignoring the incorrect one located in Folder2 which is also listed among the
editor tabs. 7) Press Ctrl-F9 to compile the project 8) Click on the "Project1.dpr" tab in the editor 9) Hold down
Ctrl and left-click (or right-click->"Open File At Cursor") on "Unit1" on the line "Unit1 in 'Unit1.pas';" in the editor.
Expected: The editor changes tabs to the correct Unit1.pas from Folder1 (as it did previously) Actual: The editor
focuses on the tab for the wrong Unit1.pas - the one located in Folder2
[QC Description]
Sometimes when you ctrl + left-click or right-click->"Open File At Cursor" the editor selects the wrong file.
This bug makes working with files from different projects, but with the same filenames, very tricky. Sometimes
when I work on the latest version of my software I may have units of the old version open in the editor (for
reference purposes). I have to be very vigilant to avoid accidentally editing the wrong file, because the IDE's ctrl
and left-click mechanism cannot always be trusted.
Refer to "steps" and the attached files for an example.

Description:
Steps:
Unused Threadcount in classes.pas
Scan classes.pas for 'ThreadCount'. You will only get three occurences. Listed below. implementation ... var ...
ThreadCount: Integer; procedure AddThread; begin InterlockedIncrement(ThreadCount); end; procedure
RemoveThread; begin InterlockedDecrement(ThreadCount); end;
[QC Description]
Classes.pas has a unit variable ThreadCount in the implementation that is added to and subtracted from. Only it
is never used. And since it is in implementation it cannot be used outside this unit. So there is a useless blocking
(interlockedexchange) call for every thread created and destroyed. It is likely old leftover code because in D5
classes.pas threadcount variable is really used, but D7 en D2006 classes.pas do not use it anymore. It cannot
be for threadsafety as interlockedexchange only synchs the variable inc/dec, nothing else.
Please remove it!

Doubleclicking project or group should only load Win32 personality
1. Install BDS with all personalities (C++, C#, Win32, .NET). 2. Create a Win32 project and save it. 3. Close
BDS. 4. Doubleclick the .bdsproj file. Wait while BDS loads all unneccesary personalities.
[QC Description]
When launching a Delphi Win32 project by doubleclicking its .bdsproj or .bdsgroup file, BDS should only load the
personality the project uses, to save some loading-time.
Alternatively, a configurator tool could be produced that allowed creating a launcher for this purpose.
I did try to modify Windows File Types, but with no success.
Manually creating a shortcut pointing to bds.exe does make it possible to launch using a single personality, but I
don't have time to create a large number of such shortcuts.

The cause of the problem is that the code in TGIFImage.Assign assumes that TGIFFrame.Create doesn't add
the frame to the parent TGIFImage and that TGIFImage.Add does. This was true in the old version but not in the
new.
The following modification fixes the problem (+ means add line, - means delete line):

Description:
TGIFImage and TGIFFrame should provide means to free the cached bitmap, mask and palette GDI objects.
[QC Description]
This functionality is needed by applications that can potentially load and display large number of GIFs.
Since an animated GIF can contain a large number of frames, and each frames uses up to two bitmap handles
and one palette handle, apllications that needs to display arbitrary number of animated GIFs must be able to limit
the GDI resource usage.
Most of the required functionality already exist, it just need to be made accesible.
The following proposed change introduces two public methods, TGIFImage.Dormant and TGIFFrame.Dormant.
The methods releases cached GDI resources.
1) Introduce the TGIFFrame FreePalette strict protected method and the Dormant public method:
procedure TGIFFrame.FreePalette;
begin
if (FLocalPalette <> 0) then
begin
DeleteObject(FLocalPalette);
FLocalPalette := 0;

Improve Tools, Options UI (allow dialog to resize or other UI changes)
Start Delphi 2007 Tools, Options Click around in the options tree and notice some ot the options screens seem
cramped in the existing small dialog (see the list in the Description for details) I've attached screenshots of how
this dialog looks once it is made resizable, and I think the results are nicer
[QC Description]
I've listed all of the options areas of the Tools Options dialog that I consider more difficult to use because the UI
seems cramped inside the existing smallish dialog. I believe an alternate UI for those areas of the settings, or
allowing this dialog to resize would make this dialog more usable.
The first 4(*) items in the list would give me a significant benefit, because I believe developers use them more
frequently.
Tools (Environment) Options (Ignoring Together)
-----------------------------------------------------------------------------Significant Benefit (central portion could resize, less scrolling, etc.):
- Library Win32 (path lists)*
- Environment Variables (variable lists)*
- Color (syntax preview)*
- Language Exceptions (exception list)*
- Native OS Exceptions (exception list)
- Event Log (color listbox very cramped)
Minor Benefit:
- Environment Options (paths)
- Object Inspector (color listbox)
- Explorer (explorer categories)
- CodeGear Debuggers (paths)
Little/No Benefit:
- Tool Palette
- Colors
- Type Library
- VCL Designer
- Editor Options
- Source Options (could resize, but large enough now)
- Display
- Key mappings (could resize, but large enough now)
- Code Insight
- Debugger Options
I'm happy to accept a better/alternate UI instead of resizing, if CodeGear can come up with one that performs the
same function in less space, but resizing is the bet option I've imagined so far. QC 9751 kind of requested this
(in the title at least), but was marked as a duplicate of an only vaguely related bug.

Steps:
Class constructors in Delphi/Win32
I would like to be able to write code for Delphi/Win32 that looks like the following example (Singleton pattern).
Currently, I have to make the class var "private" instead of "strict private", and initialize it in the unit initialization
section. This works, but it's poor encapsulation: the code for my class is not all with the class, and I have to use
a weak visibility specifier (private) instead of a properly encapsulated visibility (strict private). -------- unit
Comparers; interface type IComparer = interface function Compare(A, B: string): Integer; end;
TDefaultComparer = class(TInterfacedObject, IComparer) strict private class var FInstance: IComparer; public
class constructor Create; function Compare(A, B: string): Integer; class property Instance: IComparer read
FInstance; end; implementation uses SysUtils; { TDefaultComparer } function TDefaultComparer.Compare(A,
B: string): Integer; begin Result := AnsiCompareStr(A, B); end; class constructor TDefaultComparer.Create;
begin // run at the same time as all unit initialization, // but has access to strict private & strict protected
members FInstance := TDefaultComparer.Create; end; end.
[QC Description]
It would be nice if Delphi for Win32 supported the "class constructor" syntax that is already supported in Delphi
for .NET.
This would basically be another "initialization" section (and run at the same time as all other "initialization"
sections), but it would be scoped to the class, and therefore better encapsulated (both with regards to member
visibility, and just from the viewpoint of having all of the code that relates to the class as part of the class).
This would be particularly helpful for implementing the Singleton pattern for simple and/or null objects. See
Steps.

It is impossible to use the current Open Tools API to create a custom keybinding that affects code folding.

Collapse all methods
Collapse namespace/unit
Collapse nested procedures
Collapse regions
Since you can not determine if the current folding block is folded or not, toggling functionatly can't be provided

Many of the "Newer" windows API calls are missing completely from the codegear sources.. They are available

with the windows.pas unit).
Missing Functions: (not meant to be a complete list)
1. Replacefile - (in source already)
2. WinSock2 calls (yes these are in the Indy libs, but why not in a "regular" delphi winsock2 header unit)
3. UnregisterWaitEx - (in source already)

5. RegisterWaitForSingleObject - (in source already)
6. CreateTimerQueueTimer
7. GetComputerNameEx - (in source already)

Random paths are prepended to .dcp references

open, view Package1.dproj in Notepad. Notice the line: <DCCReference Include="rtl.dcp" /> No problem yet...
5. Back in Delphi, click File | New | Unit - Delphi for Win32. 6. Click File | Save. Save the file under the Subdir
directory as: C:\MyPackage\Subdir\Unit1.pas 7. Click File | Save All. 8. View Package1.dproj in Notepad. This
time we see: <DCCReference Include="Subdir\rtl.dcp" /> <DCCReference Include="Subdir\Unit1.pas" /> Notice
how "rtl.dcp" has changed to "Subdir\rtl.dcp". Obviously this is wrong. rtl.dcp isn't located under Subdir; it's in
the Delphi "lib" directory. Now try this: 1. Close and reopen the Delphi IDE. 2. Click File | Reopen |
C:\MyPackage\Package1.dproj. 3. In the Project Manager pane, right-click Package1.bpl and click Save. 4.
View Package1.dproj in Notepad. Now we see: <DCCReference Include="C:\Documents and
Settings\Username\Desktop\rtl.dcp" /> <DCCReference Include="Subdir\Unit1.pas" /> So apparently it just
prepends the current directory onto .dcp references? Expected behavior: It should always write "rtl.dcp" with no
path.
[QC Description]
Inside .dproj files, random paths are prepended to .dcp references when a package is saved.
This is a new issue with Delphi 2007's .dproj files. It didn't happen with Delphi 2006's .bdsproj files.

Negation of -MaxInt-1 does not cause integer overflow error.
[QC Description]
If you negate a value of -MaxInt - 1, overflow is not checked, and no overflow error is generated, even if overflow
checks are on.
Looking at the CPU window, one sees that no overflow checking code is generated:
neg dword ptr [I]
instead of:
neg dword ptr [I]

Closures / lambda / anonymous functions. (Functional programming)
[QC Description]
Please implement closures / lambda / anonymous functions. Because the topic is (I presume) widely known, I
don't insist now in benefits or in syntax descriptions. Of course, this can be implemented in Delphi using a CG
like Boehm. Related to this, explore also this possibility to have unmanaged program elements and managed
ones - but this is another topic.
My small proposal is to use an attribute like 'closure' (syntax is subject to change, of course) which will create
behind the scenes an object which will be passed, as needed. For ex.:
function Func1(aStr: string; aInt: integer): string; closure;
Will create internally something similar with the following structure
TFunc1 = class(TBaseClosure)
...
Public
_Context: somepointer; //the pointer to the context in which the code is executed
aStr: string; //the parameters with the appropriate type
aInt: integer;
Execute: string; // the result has the appropriate type
//for a procedure is a method here with no result
end;
{var}
Func1: TFunc1;
In short, we can see a closure declaration like a much more concise way to declare classes.
If someone has in his code ShowMessage(Func1('Test', 1));
the compiler will check if Func1 points to nil, if yes, then create the object, load the parameters in the object's
fields, (or pass a pointer there if we speak about variable parameters) and execute the code returning the result
(if appropriate). In fact, it's a usual way to simulate the closures, but without the overhead which is required from
the programmer's POV regarding the object's lifecycle management, class declaration, code flexibility aso. As
we saw, the 'closures' are created automatically at first call; they can be freed manually by invoking Func1.Free,
which also must set the Func1 pointer to 'nil' in order to allow their safe re-creation on a new, possible call. If
they aren't freed, the compiler must free them at the program termination. Also, explore the possibility of freeing
them earlier (when they got out of scope etc.) but, imho, because, usually, the overhead by not freeing them is
very little (in normal conditions), by simply freeing them at the program termination is already a very good
solution.

IDE\Start Page
Description:
Steps:
Welcome page feeds need cleanup
1. The single most obvious feed - DelphiFeeds.com is not there (how did they miss that one)
[QC Description]
A couple of things are wrong with the feeds on the welcome page at the moment.
2. The overlapping menus system doesn't work very well. For example, on a 1024x768 display with all dockable
areas of the IDE unpinned (collapsed) the English Community Blogs extend beyond the bottom of the screen
and one cannot get to the links at the bottom in any obvious way. Either trim them down, support scrolling or
show multiple collumns. I've attached a screen shot (englishblogs.png).
---- #2 UPDATE: Cannot reproduce even in 800x600 --------3. Some of the blogs that are listed have been dead for years and some don't load at all. Of the ones I can
access (point 2), these all have issues:
3.1. Brad Prendergast, Dan Miser doesn't seem to load at all
-- #3.1 Update: Cannot reproduce as these have been removed ----3.2. Daniel Wischnewski, Deepak Shenoy and Holger Flick hasn't updated it this year (not too bad, I suppose)
-- #3.1 Update: Cannot reproduce . Updates are appearing just fine. ---3.3 Erwien Saputra last posted in 2006, saying that it is "definitely" his last post - in fact he is not using Delphi
anymore!
----- #3.2 Update: User should be removed. RSS Feed no longer active ----3.4. Jake Jacobson's blog doesn't load correctly - you see lots of CSS markup instead of text (could of course
be his own fault, but then his blogs should not show).
----- #3.4 Update: Cannot reproduce. User has been removed. -------4. How about a "Beta Bloggers" feed? Probably, it should be a CodeGear feed that aggregates the feeds from
everyone Nick has approved as Beta Bloggers. That way it can be maintained as new beta bloggers are added
and old ones go away.

RTL\Delphi\RTL Exceptions
Description:
Steps:
Calling Halt in 'except' or 'finally' forcibly displays the exception message, and causes process to return wrong
exit code
Run this code: program Project1; uses Windows, SysUtils; begin try raise Exception.Create('xxx'); except Halt
(5); end; end. Expected results (what happened in Delphi 2.0 through 2006): 1. The process should return with
an exit code of 5. Actual results on Delphi 2007: 1. A message box is displayed: --------------------------Application Error --------------------------- Exception Exception in module Project1.exe at 00055753. xxx. -------------------------- OK --------------------------- 2. The process returns with an exit code of 1, not 5.
(JJS: Seems related to 255308 but reproducible with D2007 December Update)
[QC Description]
This is a new problem introduced in Delphi 2007 (and still repro with the Dec2007 update installed):
If Halt is called inside an 'except' or 'finally' block, the current exception's message is forcibly displayed on the
screen, and the process returns with an exit code of 1 instead of the exit code specified in the Halt call.
The cause appears to be these lines in SysUtils' DoneException procedure, which are new to Delphi 2007:
if ExceptObject <> nil then
ExceptHandler(ExceptObject, ExceptAddr);
I assume the intention there is to ensure that any new exceptions raised during termination are brought to the
attention of the user.
In my case, however (see the example code), the exception was raised before termination commenced.
DoneException should ignore such pre-existing exceptions. And it certainly should not be changing my exit code
from 5 to 1.

processor may access 4 bytes starting from the memory address for a 32-bit operand size, using by the
following relationship: Effective Address + (4 x (BitOffset DIV 32)) Or, it may access 2 bytes starting from the
memory address for a 16-bit operand, using this relationship: Effective Address + (2 x (BitOffset DIV 16)) It may
do so even when only a single byte needs to be accessed to reach the given bit. When using this bit addressing
mechanism, software should avoid referencing areas of memory close to address space holes. In particular, it
should avoid references to memory-mapped I/O registers. Instead, software should use the MOV instructions to
load from or store to these addresses, and use the register form of these instructions to manipulate the data.
<<<<< The compiler should recognize that the start of the set it wants to check is less then 4 bytes from the end
of the containing type and should use a single byte mov to read the value into a register first. And before
someone says that the example above is not realistic, the problem can also be seen by just having an object
with a byte sized set as last field which is preceded by 3 other byte sized fields and the memory that's allocated
for the object just happens to be in front of a page boundary... Cheers, Thorsten --

Documentation
Description:
Steps:
Screen Scaling and Changescale
Changescale fails in some instances which have been traced to the following: 1. Changescale is dependent on
the "Border Style" property of forms. When BorderStyle is "Single" the user can not resize the form manually and Changescale feels free to adjust form size as would be expected. However, if a form's BorderStyle is
"Sizeable", changescale fails, as if believing the user can take care of sizing. The developer does not expect
the form sizing to fail. 2. Changescale is sensative to columns in a DBGrid which have been sized by the
developer. Changescale will fail on such columns. This can result in a DBGrid component and Form being
adjusted by Changescale, but the Columns in the DBGrid Not being resized. (BTW, the developer can not
remove the column sizing through normal use of the IDE. So, this problem is not easily corrected. In Form Text
mode the developer can remove the Width statement on the column definition.)
[QC Description]
Poor documentation of managing form scaling for various user screen resolutions has produced many
newsgroup threads with rare satisfactory resolutions.
Failure is now traced to undocumented behavior in "Changescale". Documentation of this statement should be
completed.
Functionality change may not be desireable, but accurate documentation would help.

[QC Description]
After some editing, compiling and searching, I often get an invalid pointer operation with a following 'List out of
bounds', and sometimes other consequential errors just as I open the Search / Find in files dialog.
It occurs when I press ALT-S, F, SHIFT-TAB
I must always restart Delphi afterwards.
I had the same problem with Delphi 5.
I suspect the message window to be somehow involved.

begin try s except on EAbort do end; Writeln('OK'); end.
(JJS: Reproducible with the integration build but not with the developer build)
[QC Description]
SysUtils.Abort may cause an AV exception if a call to the Abort is maked from a procedure, that uses EBP as a
local variable.
Source for SysUtils.Abort in 2006:
procedure Abort;
function ReturnAddr: Pointer;
asm
MOV EAX,[EBP + 4]
end;
begin
raise EAbort.CreateRes(@SOperationAborted) at ReturnAddr;
end;
Source in Delphi 4
procedure Abort;
function ReturnAddr: Pointer;
asm
MOV EAX,[EBP - 4]
end;
begin
raise EAbort.Create(SOperationAborted) at ReturnAddr;
end;
The defference is that Delphi 4 version has a compiler-generated local variable for loading resource string. So
compiler saves old value of EBP and assigns it to ESP.
But in Delphi 2006 resource string is acceessed by a @ reference and there is no need in such a local variable
and value if EBP is preserved and it has a value from the calling procedure.
Sometimes it can hold a local variable.

Generics in Delphi32
Steps:
// Principale use CSumContainerElt = concept ( record ) // restrict its use with record (or value type) class

(sorry for my English)
function TSumContainer<TElt>.Sum: TElt; var Elt : TElt; begin Result := TElt.NullValue; for Elt in FArrayElt do
According to the Delphi roadmap (http://dn.codegear.com/article/36620), generics (or "parameterized types") will Result := Result + Elt; end; function TSumContainer<TElt>.ToString: string; var Elt : TElt; begin Result := ''; for
be availiable in Delphi "Tibur n".
Elt in FArrayElt do Result := Result + Elt.ToString; end; //Use TMyRecord = record ( CSumContainerElt ) // or
create a key word ex "assume" : class ( ancestor, interfaces ) assume ( concepts ... ) private FNumber :
But .Net generics have many restrictions ; this kind of code is not allowed :
Cardinal; class function GetNullValue : TMyRecord; public class property NullValue : TMyRecord read
TGenericSum<Type> = class
GetNullValue; class operator Add( const Left,Right : TMyRecord ); function WriteString : string;
class function Sum(const Left,Right: Type): Type; static;
CSumContainerElt.ToString = WriteString; // Like for interface (in case of mutiple concept assumed // or if you
end;
can't change the class/record but providing a method matching with a concept method expected) end; THelpInt
class function TGenericSum<Type>.Sum(const Left,Right: Type): Type;
begin
Result := Left + Right; // Has Type an operator Add ???
end;
= record helper for Integer ( CSumContainerElt ) private class function GetNullValue : Integer; public function
ToString : string; class property NullValue : Integer read GetNullValue; end; TSumMyRecord =
TSumContainer<TMyRecord>; TSumInteger = TSumContainer<Integer>;
C++ templates permit this but generate complexes errors cases if a type can't use with a template (verifications
are do only when the code for a template is creating).
.Net constraints are a good idea but extend them will produce hard reading code :
TMyGeneric<Type:operator Add, operator Subtract, operator ..... > //help !
So what i propose : a new key word to specifie what kind of type is allowed for the generic.
The next C++ standard can also introduce this feature (http://www.openstd.org/jtc1/sc22/wg21/docs/papers/2006/n2081.pdf).
With this generics in Delphi would be as powerfull as C++ template but with a easy to read code.
This new key word would work as interfaces but only at compiling time and could be used with class, record,
class helper and record helper.
Exemples of possible use (with a "concept" key word) below.

This is a really minor thing and not actually a bug, but I thought I'd report it anyway:
Tools | Configure Tools
Click Add..
Give any title
For Program, give "c:\Path with Spaces\bin\<exename>.exe". Be sure to include the surrounding double quotes
Click OK

From the main IDE Tools menu choose the item you jsut added
While adding a "tool" application in the "Configure Tools" dialog, I pasted the path to the program from a link on
the desktop. It was pasted as is, including the enclosing quote characters:
"c:\Program Files\...\some_tool.exe"
The IDE couldn't run it, apparently because it saved the link with the quotes and then tried to enclose it into
another pair of quotes before launching the app. After going back to the "Configure Tools" dlg and manually
removing the quotes, all worked fine.
I know it was really my fault and the delimiters should not be there in the first place, but it was really easy to
make such a mistake. Wouldn't it be nice to include a simplest check to remove the outer level quotes, if any,
before storing the data?

i don't know if this bug is still in Delphi 2005 - 2006 - 2007.
in the object TMultipartContentParser:
procedure TMultipartContentParser.BufferContent;
var
L, R: Integer;
P: PChar;
begin
if (WebRequest.ContentLength > 0) and (FContentBuffer = '') then
begin
FContentBuffer := WebRequest.Content;
if Length(WebRequest.Content) < WebRequest.ContentLength then
begin
L := Length(FContentBuffer);
SetLength(FContentBuffer, WebRequest.ContentLength);
P := PChar(FContentBuffer) + L;
while L < WebRequest.ContentLength do
begin
R := WebRequest.ReadClient(P^, WebRequest.ContentLength - L);
if R = 0 then break;
Inc(L, R);
Inc(P, R);
end;
end;
end;
end;
you see the instruction :
begin
Inc(L, R);
Inc(P, R);
end;
It's a disaster ! in some condition this will result as an indefinitly loop (with 100% CPU usage)
I gave you one indice :
function TISAPIRequest.ReadClient(var Buffer; Count: Integer): Integer;
begin
Result := Count;
if not ECB.ReadClient(ECB.ConnID, @Buffer, DWORD(Result)) then
Result := -1;
end;
so you understand :) the function ReadClient give a result of -1 and not 0 if she not success !!!!!!!!!!
so
begin
Inc(L, R);
Inc(P, R);
end;
Give an infinite loop if the client for exemple send a big file and stop suddenly the connection because the
condition (if R = 0 then break;) will be never true

There is a number of commands in "Edit..." submenu (of the main menu) that are specific to the form designer:
these are all commands starting from "Align to grid..." and below.
When editing a unit (not even a form), all these commands remain visible and many of them ("Align...", "Size..."
and all below them) are even enabled, although they obviously can't do anything useful in this context.
Solution: hide these commands when not in Designer.

Steps:
PopupMode=pmExplicit doesn't handle correctly the closing of forms in certain cases
ref:238588, possible dup.
[QC Description]
Hi,
Compile & run the attached program. Also, read the instructions on the forms.
When a (secondary) form has the PopupMode=pmExplicit and PopupParent the main form, then, if, while the
2ndary form is open, the focus is switched to another program and back, by closing the 2ndary form (which
implicitly should bring the focus to the Delphi application), the main form is sent in back to the program which
was focused at some moment in time. Compile & run the attached program. Be sure to read the instructions
written on the forms to reproduce the bug. (Note: The behavior is the same even I assign the properties in code
or in OI, at design-time).

Renaming interfaces in a remote datamodule will trash source files
1) Create a remote datamodule with some interfaces 2) Implement some methods 3) Rename the interfaces

trashed.
[QC Description]
After renaming some interfaces in a remote datamodule with some child datamodules, the source files where
trashed. Here some examples:
What was
class procedure TADMINQueryEngine.UpdateRegistry
became, after renaming IADMINQueryEngine to IS3DQueryEngine
class procedure TS3DQueryEnS3DQueryEnginetry
function TADMINQueryEngine.ExecuteSearch
became
function TS3DQueryEngiS3DQueryEngine
function TADMINQueryEngine.GetSessionFileData
became
TS3DQueryEngineS3DQueryEngineata
It looks something went wrong in refactoring, it looks it repeats parts of the new string and overwrites the old one
partially.
Also a datamodule is turned into a form. It contains form properties (open in in text view)

[QC Description]
Please eliminate all automatic and uncontrollable alpahabetization in Project Manager for all personalities.
Currently in Delphi alphabetization is automatic and enforced at all times. I prefer to keep libs, resource files, etc
together at the bottom of the list since I cannot edit thes files in the IDE. Others may wish to group files by topic.
PM does not allow reording files at all in the Delphi personality.
In C++, the situation is worse because the order of files in PM controls the build order. User can drag and drop
files into a different order, but the files are realphabetized every time a new file is added to the project QC61376
or when the view is changed QC61372.
I would like to see all forced reordering of the PM file list eliminated and optional alphabetization implemented
instead. Ideally this would include an option to alphabetize now as well as an option to turn on automatic
alphabetization as currently enforced in Delphi.

variable. Furthermore the Abort::ReturnAddress function doesn't return the return address of Abort but the return
address of the caller. This is because SysUtils.Abort doesn't have a stack frame.

The design time packages are not distinguishable in the project manager
The Runtime, Design time, and combined(runtime/design time) packages have the same icons in the project
manager. This makes it difficult to figure out which package from the project group has to be installed. 1. Open
a project group containing Design Time and Runtime packages. 2. They all have the same icon. There is no
visual difference between them, and you have to try them one by one to see which one can be installed in the
IDE, and which one can't.

Steps:
Rebuilding packages in a project group.
1. Create a project group with multiple packages dependant on each other. 2. Build and install all the packages.
3. Make a change in a class name in the hierarchy of dependencies and start a "Build All". The build will go
very slow as the packages are uninstalled installed all the time during the build, and a number or errors will
popup.
[QC Description]
When rebuilding the packages in a project group every package is uninstalled prior to its rebuild, and installed
immediately after that. This makes the rebuild enormously slow as all dependant packages are also reinstalled
over and over again often taking longer than the compilation itself.
In addition when a change is made in a class name in a package and the package is recompiled all dependant
packages start throwing a massive amount of popup error messages.
All those problems can be fixed if when "rebuilding all" the packages in the project group are uninstalled first and
installed after the full rebuild is finished.
The rebuild process will be significantly faster and there will be no annoying popup error messages.

Assert(U = #$0424); // Assertion fails! end. Actual result: The last assertion fails. Expected result: No assertion
failures.
[QC Description]
When a UnicodeString is assigned to an AnsiString, _LStrFromPWCharLen writes 0 in the AnsiString's code
page field.
This is inconsistent with _NewAnsiString, which initializes the code page field to DefaultSystemCodePage. (0 is
translated to DefaultSystemCodePage internally.)
As a consequence of this bug, string conversions do not round-trip correctly when a custom
DefaultSystemCodePage setting is used. (See Test #2)
Suggested fix:
procedure _LStrFromPWCharLen(var Dest: AnsiString; Source: PWideChar; Length: Integer; CodePage: Word);
var
DestLen: Integer;
begin
if Length <= 0 then
begin
_LStrClr(Dest);
Exit;
end;
// ADD THESE TWO LINES:
if CodePage = 0 then
CodePage := DefaultSystemCodePage;
DestLen := CharFromWChar(nil, 0, Source, Length, CodePage);

begin
CharFromWChar(Pointer(Dest), DestLen, Source, Length, CodePage);
PStrRec(Integer(Pointer(Dest)) - skew).codePage := CodePage;

TBCDField error size 255

For some BCD fields where the value is calculated using sum, nvl or sub-query in

the iunits2 has value 255. That is out of bounds and the DataSet tries to define the field with size of 255. The
result is 'Invalid field size'.
By debugging and changing the field size to 32 (On informix IDS server I don't know whenever the max value
depeneds on server type) the program worked ok. With value higher of 32 also results 'BCD overflow'.
However I can't find a way to change this behaviour. Please if someone could give me a hint how to replace the
255 with 32 in source. It would help me a lot as I must soon deploy the application to a client.

Writeln(E.Classname, ': ', E.Message); end; end. Test #2 - Length left at new value following EOutOfMemory:
var S: TStringBuilder; begin try S := TStringBuilder.Create; try // This raises EOutOfMemory on my VM with 384
MB RAM. // On a system with more memory, you'll probably have to issue a few // large GetMem's first for this

except on E:Exception do Writeln(E.Classname, ': ', E.Message); end; end.
[QC Description]
TStringBuilder.set_Length issues:
- It silently accepts a negative Value. It should raise an exception as .NET does. (Note that Append can feed
negative Values to set_Length when "Length := Length + ..." overflows.)
- It updates FLength *before* expanding the capacity. Problem there is, if ExpandCapacity raises
EOutOfMemory, FLength will be left holding the new value. This can lead to heap corruption if the application
tries to write FLength bytes afterward.
- In ExpandCapacity, "Length * 2" could overflow. It should fall back to setting a capacity of Length in that case.

TDBRichEdit doesn't save it's changes in certain circumstances
To test it, do a simple app with a TDataSet, TDBGrid and a TDBRichEdit connected to one of TDataSet's fields.
Add two buttons with the following OnClick handlers: procedure TfrmMain.Button1Click(Sender: TObject); begin
with DBRichEdit1.Paragraph do Alignment:=taCenter; end; procedure TfrmMain.Button2Click(Sender: TObject);
begin with DBRichEdit1.SelAttributes do Size:=Size+5; end; Add some records. Make sure that you fill in
something in the rich edit. Commit. Go to any record which has some text in the DB rich edit. Make sure that
TDataSet is in dsBrowse state (look at TDBGrid indicator). Make a selection. Press the Button1 once and
Button2 several times. The text must be centered and the font selection size must grow. Note that the
TDBGrid's indicator remains unchanged. Go to another record (in order to "save" the data). Return back. EXP:
The changes must be persisted. The font size must be bigger. Alignment: Centered. ACTUAL: The changes are
not saved.
[QC Description]
Hi,
If we have a TDBRichEdit bound to a field F1 and F1's TDataSet is in dsBrowse mode, then by using
SelAttributes and/or Paragraph properties in order to change the RTF format, the F1.DataSet doesn't enter in
edit mode and the changes are not saved.
See steps for how to reproduce the problem.
Proposed fix:
-----------Add to TDBRichEdit the RichEdit unit to the Uses clause in order to allow you to add the following private
procedures (the messages are defined in RichEdit.pas):
procedure EMSetCharFormat(var Message: TMessage); message EM_SETCHARFORMAT;
procedure EMSetParaFormat(var Message: TMessage); message EM_SETPARAFORMAT;
with the bodies
procedure TDBRichEdit.EMSetCharFormat(var Message: TMessage);
begin
BeginEditing;
inherited;
end;
procedure TDBRichEdit.EMSetParaFormat(var Message: TMessage);
begin

4. write code:
begin
if ClientDataSet1.Locate('CHARFIELD', edit1.text, []) then
showmessage('Found');

then run it.
I used a table with an unicode column.
I can see the date by DBGrid, and I can edit or insert it.
But, ClientDataSet just can locate English string. can't work with Greek, Hebrew, and Chinese.
I copy the string from DBGrid to Edit directly, but it can't work too.

This error occur because there is a bug in dbExpress components. The solution is down, for anyone who is
interested.
When I call a procedure inside a package of another owner, using a TSQLStoredProc component, I always get a
error 'Identifier (package.proc) must be declared' because It doesn´t put the owner of the package in front of the

Steps:
TDBRichEdit forces its DataSet to be in editing state when the application starts
TDBXTiburonBugsSuite.managed.db.test.exe connection=BLACKFISHSQLCONNECTION s:TestRaid_265189
[QC Description]
Hi,
--or--
if the following conditions applies:
1. The DataSet is opened at design time. (ie. when we start the app, the DataSet is already Active).
2. We have on the form a TDBRichEdit visible /and/ already bound to a field from above DataSet...
...then the DataSet is already in the Edit state when the app starts.
1. Make a simple DB app with a TDataSet descendant. Put a TDBRichEdit on the main form and link it to one of
the fields. Make sure that TDataSet instance is open by setting Active := True.
2. Run the application. Add some records. Commit if necesary. Close.
3. (Re)run the app. You'll see that the TDataSet's state is dsEdit. (You can see this by, eg. putting a TDBGrid
and/or TDBNavigator on form or inspecting the property directly in code - something like if
DataSet1.State=dsEdit then ShowMessage('problem');).
The cause is that
Note: The above behavior should be seen also at step 2, but I didn't tested it.
a.) We have
begin
BeginEditing;
inherited;
end;
...which is needed in order to save the DBRichEdit's formatting
and
b.) TCustomRichEdit (the ancestor of TDBRichEdit) has the nasty behavior to send to itself
EM_SETCHARFORMAT as a result of its initialization process (if you have time, see
TCustomRichEdit.CreateWnd for details). In fact the 'problematic' code is
procedure TTextAttributes.SetAttributes(var Format: TCharFormat2);
var
Flag: Longint;
begin
if FType = atSelected then Flag := SCF_SELECTION
else Flag := 0;
if RichEdit.HandleAllocated then
SendStructMessage(RichEdit.Handle, EM_SETCHARFORMAT, Flag, Format);
end;
...which is called when TCustomRichEdit sets it's DefaultAttributes.
Proposed fix:
---------------Add the following lines (marked bellow with //+) in TDBRichEdit's class interface:
TDBRichEdit = class(TCustomRichEdit)
private
FCreatingWnd: integer; //+
...
protected
procedure CreateWnd; override; //+
...
...and in the class implementation add:
procedure TDBRichEdit.CreateWnd;
begin
inc(FCreatingWnd);
try
inherited;
finally
dec(FCreatingWnd);
end;
end;
...as well as replace the old TDBRichEdit.EMSetCharFormat with:
begin
if FCreatingWnd=0 then
BeginEditing;
inherited;
end;
-8<-------8<---- Implemented & tested in FT .3163
...Of course you can declare FCreatingWnd as a Boolean but imho having an integer is a more flexible solution.

The steps has a function with a list of examples with the type displayed in comments. The correct code is run
and code completion displays the correct stuff, only help insight is wrong.
I didn't include all as every single function with these data types displays the wrong info. Note that most of them

Steps:
TTreeView.SaveToFile does not support TEncoding
1. Drop a TTreeView on a form. 2. Populate the tree with several nodes. Be sure that at least one node has
Unicode characters in its caption. I suggest putting the Unicode characters in the first node as the problem will
[QC Description]
There is only one version of the TTreeView.SaveToFile method, and it does NOT take a TEncoding parameter.
The problem with this is that if the tree nodes contain any Unicode characters in their captions, the resulting file
cannot be successfully loaded back into the tree.
be more obvious. 3. Drop a button on the form - Caption = Save. 4. Write an event handler for the button and
call TreeView1.SaveToFile( ) specifying a file name. 5. Drop another button on the form - Caption = Load. 6.
Write an event handler for the Load button and call TreeView1.LoadFromFile() specifying the same file name
from step 4. 7. Run the program. Click the Save button. Check the resulting file. The text is readable by
Notepad, but there is no BOM in the file. Next, Click the Load button. The nodes are not correctly loaded and
the tree is corrupted.
The root cause of the problem is in the TTreeStrings.SaveTreeToStream method. This method scans through
the nodes of the tree basically creating a string for each node prefixed by a tab character for every level deep in
the tree the node is, and followed by a CR-LF to indicate the end of line. Each string is then written to the
stream. The correct number of bytes is written because the ByteLength( NodeStr) method is used.
However, what is missing is that since no encoding is used, there is no BOM at the beginning of the file.
So, when you go and use the TTreeView.LoadFromFile method, which calls
TTreeStrings.LoadTreeFromStream, there is no BOM in the file, and so the load thinks the data is Ansi data, and
this causes the file to be processed incorrectly.
---One way to solve this problem is to use a temporary string list inside the SaveTreeToStrings method instead of
writing directly to the stream. That is, use the temporary string list to build up the list of node items (no need to
use EndOfLine because it is in a string list.) Then at the end, use the TStringList.SaveToFile method to save the
file. Of course, you would also have to add overloaded methods for TTreeView.SaveToFile and
TTreeView.LoadFromFile to accept TEncoding parameters. But these would get passed to the string list method
calls. The same is true for the LoadTreeFromStream method, but in that case, the method already uses a temp
string list to load the file/stream.

However, with D2009 - it appears it gives it a random name - such as
"ATT00003.dat" / "ATT00008.dat" etc.
More importantly, it changes the description to DAT - so if your original file was an excel, pdf etc - they all get
changed to "*.dat" - making it impossible for user to open the attachment.

Comparing PChar to single char literal fails in Delphi 2009
Enter this code into a new Delphi console project: program Project141; {$APPTYPE CONSOLE} uses SysUtils;
procedure Test; var P: PChar; begin P := '@'; if P <> '@' then Writeln('@ <> @') else Writeln('@ = @'); end;
begin try Test; Readln; except on E: Exception do Writeln(E.ClassName, ': ', E.Message); end; end. And run it.
Exp: output '@ = @' Act: output '@ <> @'
[QC Description]
If you do:
var
P: PChar;
begin
P := '@'; // all is fine, point PChar to literal
if P <> '@' then // here it goes wrong
etc...
It appears that the comparison tries to compare a UnicodeString and a ShortString without any conversion of
either of them. This does not happen if you use, say, 'Hello', instead of '@'.
Take a look at the CPU view:
Project141.dpr.12: P := '@';
0040A915 B894A94000 mov eax,$0040a994
0040A91A 8945FC mov [ebp-$04],eax
Project141.dpr.13: if P <> '@' then
0040A91D 8D45F8 lea eax,[ebp-$08]
0040A920 8B55FC mov edx,[ebp-$04]
0040A923 E850A9FFFF call @UStrFromPWChar
0040A928 8B45F8 mov eax,[ebp-$08]
0040A92B BA98A94000 mov edx,$0040a998
0040A930 33C9 xor ecx,ecx
0040A932 8A08 mov cl,[eax]
0040A934 41 inc ecx
0040A935 E8028BFFFF call @AStrCmp
0040A93A 741B jz $0040a957
As you can see, P is converted to a UnicodeString, and that is passed to AStrCmp as one of the parameters,
which is incorrect! The other parameter, the string at address $0040a998, is a short string (bytes 01 40 00).

Database\DBExpress
Description:
Steps:
D2009 dbExpress wrongly uses WideString where D20007 used String
I can't know what you need to reproduce it because I don't know what mechanism dbExpress uses to decide if
[QC Description]
a database is Unicode.
Our Oracle applications in D2007 use String for *all* fields of all tables and stored procedures, never WideString.
I think it's very likely that if you create a Oracle10g database with characterset WE8ISO8859P15 and connect
using this client:
Just recompiling in D2009 *all* querys and stored procedures fail with type mismatch errors "expecting String
actual WideString".
http://download.oracle.com/otn/nt/instantclient/10204/instantclient-basic-win32-10.2.0.4.zip
My guess is that D2009 is wrongly identifying our database as Unicode. I don't know how D2009 identifies if an
Oracle10 database is Unicode-enabled or not, but in our case it must be doing it the wrong way.
I think the right way should be something like:
SELECT value FROM nls_database_parameters
where parameter = 'NLS_CHARACTERSET'
In our database that query returns WE8ISO8859P15. Unless that query returns UTF8, UTF16... you shouldn't
force us to use Widestrings.
For us using Widestrings throughout all our applications, combined with QC 4790 is a real showstopper.
(An alternative solution would be to add a property SqlConnection.UseUnicode with values
Always/Never/Default, so users could decide themselves if they want to use WideStrings).
Example of a query in D2007:
object ConexionOracle: TSQLConnection
ConnectionName = 'Oracledesarrollo'
DriverName = 'Oracle'
GetDriverFunc = 'getSQLDriverORACLE'
LibraryName = 'dbxora30.dll'
Params.Strings = (
'DriverName=Oracle'
'DriverUnit=DBXDynalink'
'DriverPackageLoader=TDBXDynalinkDriverLoader,DBXDynalinkDriver10' +

'blicKeyToken=91d62ebb5b0d1b1b'

you can reproduce it.

'tory,Borland.Data.DbxReadOnlyMetaData,Version=11.0.5000.0,Cultur' +
'e=neutral,PublicKeyToken=91d62ebb5b0d1b1b'

'Multiple Transaction=False'
'Trim Char=False'
'Decimal Separator=,')
TableScope = [tsSynonym, tsTable, tsView]
VendorLib = 'OCI.DLL'
Left = 88
Top = 24
end
object QRoles: TSQLQuery
MaxBlobSize = -1

SQL.Strings = (

'FROM SESSION_ROLES'
'')
SQLConnection = ConexionOracle
Left = 216
Top = 24
object QRolesROLE: TStringField
FieldName = 'ROLE'
Size = 30
end
end
As you can see, the field is returned as string. If I try to repeat that in D2009 I get this:

GetDriverFunc = 'getSQLDriverORACLE'

Steps:
Missing Unicode documentation
[QC Description]
Project Options|Compiling has this:
Long strings by default Delphi for Win32 only. This option (equivalent to the $H directive) controls the meaning of
the reserved word string when used alone in a type declaration. The generic type string can represent either a
long, dynamically-allocated string (the fundamental type AnsiString) or a short, statically allocated string (the
fundamental type ShortString). By default, Delphi defines the generic string type to be the long AnsiString.
All components in the component libraries are compiled in this state. If you write components, they should also
use long strings, as should any code that receives data from component library string-type properties. The
disabled (equivalent to {$H-}) state is mostly useful for using code from versions of Delphi that used short strings
by default. You can locally override the meaning of string-type definitions to ensure generation of short strings.
You can also change declarations of short string types to string[255] or ShortString, which are unambiguous and
independent of the enabled option. Default = True
Which needs updating for Unicode strings.

TreeView doesn't load Unicode files
Proposed solution (see also the Workaround for complete details): const Encoding: TEncoding = nil Add
Encoding parameter to the following routines in ComCtrls.pas: TCustomTreeView.LoadFromFile (lines 1520
and 11414) Call LoadFromStream (line 11420) TCustomTreeView.LoadFromStream (lines 1521 and 11426)
Call LoadTreeFromStream (line 11430) TTreeStrings.LoadTreeFromStream (lines 10015) The LoadFromFile
would pass it to LoadFromStream which would pass it to LoadTreeFromStream which could then pass it on to
the List.LoadFromStream (line 10027). I'm not sure if the same is also needed for the SaveToFile, since that
seems to work fine.
[QC Description]
The TTreeview is unable to load itself from Unicode files. You can have nodes with Unicode Text, and save this
correctly. But when you load them, they will be loaded as ASCII which shows garbage in the treeview of course.
Cause: TTreeView LoadFromFile, implemented as TCustomTreeView.LoadFromFile has no Encoding
parameter and calls TCustomTreeView.LoadFromStream which in turn calls
TTreeStrings.LoadTreeFromStream, again passing no Encoding.
LoadTreeFromStream uses a List.LoadFromStream, passing no Encoding (this is the place where an Encoding
could be passed).

AutoUnloadDriver is not working as is
1. Create a new VCL application 2. Drop a TSQLConnection (SQLConnection1) instance and define properties
for Interbase connection. To enable AutoUnloadDriver, add a new param (AutoUnloadDriver=True) into
SQLConnection.Params 3. Drop a TButton (Button1) and write OnClick event: SQLConnection1.Open; 4. Drop
another TButton (Button2) and write OnClick event: SQLConnection1.Close; 5. Run the application in debug
mode. Make sure you bring out a "Event Log" debug window to trace how the database connection dll is loaded
and unloaded. 6. Press Button1 to open the database connection, the Event Log windows will show database
connection library has loaded. 7. Press Button2 to Close the database connection, the event log windows show
nothing about the database connection library. 8. Close the application will only unload the database
connection library.
[QC Description]
In Delphi 2009 DBX4 framework, there is a new property TDBXPropertyNames.AutoUnloadDriver. This is state
in the DBXCommon.pas about the property:
"If set to true, dynalink drivers will automatically unload their dll, when there are no longer any open connections
that use the driver."
I expect setting the property to true will make the database connection library to be unloaded when connection is
closed.
However, I find no way to activate this function thru current DBX4 implementation.
After tracing the DBX source code, I found the cause of the problem. The Dynalink Driver class has the following
constructor:
constructor TDBXDynalinkDriver.Create(DBXDriverDef: TDBXDriverDef; DBXDriverLoader:
TDBXDynalinkDriverCommonLoaderClass);
begin
inherited Create(DBXDriverDef);
FDriverLoaderClass := DBXDriverLoader;
// '' makes this the default command factory.
//
AddCommandFactory('', CreateDynalinkCommand);
if (DriverProperties = nil) or not DriverProperties.GetBoolean(TDBXPropertyNames.AutoUnloadDriver) then
CacheUntilFinalization;
end;
To make AutoUnloadDriver work as it should, the clue is to avoid invoke CacheUntilFinalization in the
constructor. In order to do that, we must make sure DriverProperties is not nil and AutoUnloadDriver property
has value "True".

It looks like the code below is in TForm but limited by the FSizeChanging boolean that is not used anywhere.
My guess is that FSizeChanging was suppose to be set during WMEnterSizeMove or something like that. Just
a guess. This is my solution below that ignores that flag. procedure TsdForm.WMGetMinMaxInfo(var Message:
TWMGetMinMaxInfo); begin inherited; with Message.MinMaxInfo^, Constraints do begin with ptMinTrackSize

TXMLDocument can not pharse XML document with non-english characters.
[QC Description]
When the following codes are executing, an error poped up with message : "Invalid character in the document".
There are some Chinese text encoded by UTF8 in the document, and the codes are:
XMLDocument.XML.clear;
XMLDocument.XML.LoadFromFile(XMLFilename);
XMLDocument.Active := True;
or
XMLDocument.XML.clear;
XMLDocument.XML.LoadFromFile(XMLFilename, TEncoding.UTF8);
XMLDocument.Active := True;
Once the XMLDocument.Active is set to True, the error poped up. I can image the problem is caused by
TStrings and XMLDocument internal logic conflicted.
Because classic XMLDocument used TStrings as AnsiString list, but TStrings were replaced with
"TUnicodeString", so the XMLDocument logic will get unicode string to "DECODE" again.....
Therefore this error will poped up..... Please fix it ASAP, because TXMLDocument is used very frequently.

Problem with trancparency of PNG files in TImageList (black borders)
I've attached a zip files which contains a screen shot of this problem for a quick review. Moreover, the subfolder
IMG contains those images which do not work properly. But those are just sample files as others do not work
either. I provided some units which show the problem after opening in the IDE: 1) Unit31 was given to me by
Rudy Velthuis who tried to reproduce this issue. He used some PNG files from the GlyFX subfolder installed
with D2009. You will noticed that there are no black borders on the top toolbar I've added a new image list
(MyImageList) and added the files from the attached IMG subfolder and did get no black borders, too, as could
be seen in the lower toolbar. 2) So I've created a new form (Unit32) and *copied* the image list (MyImageList)
from Unit31 to it - no drawing issues either. 3) I've created a new form (Unit33), added a *new* image list,
inserted the PNG files from IMG subfolder and voila, black border are there. So there is really no way to
reproduce this problem for sure, however Rudy stated he got black borders in Unit33 on his machine, as well. I
even tried to solve this on a different Windows installation with different graphics drivers, to no avail either. I
also tried different PNG files, those from the GlyFX subfolder, but did get those black borders again. Of course,

Hi,

byte offsets, when, according to MSDN, they should be character offsets:

Replace Longint() casts with character pointer subtraction:

Class identifier is not recognized as class in type constraint in generics
program BTS266080;
[QC Description]
The very common task is to use object list with object of specified type. Usually it can be done by using
TObjectList<TSomeClass>. There is the following declaration in Generics.Collections.pas:
type
TObjectList<T: class> = class(TList<T>)
Here TObjectList is a TList descendant with more restrictive type constraint.
Now, suppose that we need a list of objects with additional functionality. For example, new class can provide
search by specific properties of the objects in the list:
type
TSomeClass = class(...)
property SomeCoolProp: TSomeType;
end;
{$APPTYPE CONSOLE}
uses
type
TSomeAbstractClass = class
end;
TSomeAbstractClassList<T: TSomeAbstractClass> = class(TObjectList<T>)
end;
begin
WriteLn('PASS'); // PASS on compile //
end.
You'll get "[DCC Error] Unit1.pas(32): E2511 Type parameter 'T' must be a class type".
TSomeClassList = class(TObjectList<TSomeClass>)
function FindBySomeCoolProp(const AValue: TSomeType): TSomeClass;
end;
Expected result: the compilation will be successfull.
And what if TSomeClass is actually some abstract class like TStrings? Real work will be implemented in it's
descendants. And we need the list of TSomeClass's descendants. So it is naturally to make TSomeClassList to
be some generic class:
P.S. The generic type TObjectList has "class" constraint => T in TObjectList is required to be any class. "T:
TSomeAbstractClass" explictly says that T is a class (it is TSomeAbstractClass class or one of it's
descendants).
type
TSomeClass = class(...)
property SomeCoolProp: TSomeType;
end;
TSomeClassList<T: TSomeClass> = class(TObjectList<T>)
function FindBySomeCoolProp(const AValue: TSomeType): T;
end;
Here TSomeClassList is a TObjectList descendant with more restrictive type constraint.
It is the same situation as "TList -> TList<T>" + "TObjectList -> TObjectList<T: class>". Just replaced TObjectList
with TSomeClassList and TList with TObjectList.
The problem is that the last declaration above will not compile - see steps to reproduce and a workaround.

Description:
TList<T>.Exchange() and TList<T>.Move() Missing
[QC Description]
The TList<T>.Exchange() method is missing in Delphi 2009. There are 2 primary reasons why this is a highly
visible problem:
1. It means that TList<T> lacks source-level interface compatibility with TList. Anyone wanting to migrate their
code from TList to TList<T> will end up needing to reimplement these missing methods. (Aside: Exchange() and
Move() aren't the only missing methods, there's others. And it'd be nice if the new methods from TList<T> could
be implemented in TList.)
2. This is the real deal-breaker. Anyone trying to reimplement Exchange() or Move() in TList<T> themselves will
end up triggering notifications that didn't occur with TList. This is particularly problematic with anyone using
TObjectList<T> with OwnsObjects = True (which it is by default). The common idiom of
procedure TMyObjectList<T>.Exchange(const Index1, Index2: T);
var
Tmp: T;
begin
Tmp := Items[Index1];
Items[Index1] := Items[Index2];
Items[Index2] := Tmp;
end;
is going to cause Notify() to be called and trigger the freeing of the objects being exchanged.
For the particular case of TObjectList<T> one could cache the current value of OwnsObjects and make sure to
turn it off before doing the swap. However, this doesn't help anyone who might be using something from the
TList heirarchy to do more complex notifications, whether it be by subclassing TList with a custom Notify
implementation or using the new OnNotify property afforded by TList<T>.
What's more, this apparently can't be implemented via class helpers, as the following code will cause the
compiler to throw the following error: [Pascal Error] afGenerics.pas(9): E2508 type parameters not allowed on
this type
type
TListHelper<T> = class helper for TList<T>

Steps:
Missing test in TListBoxStrings.Insert, causes the box to lose object
- Select File -> New -> VCL Forms Application from the menu. - Put a ListBox on the form. - Insert this code to
the OnCreate event handler of the form. ListBox1.Items.InsertObject(-1, 'SomeString', Self); Assert
(ListBox1.Items.Objects[ListBox1.Items.IndexOf('SomeString')] <> nil, 'Object is nil'); Expected: nothing
happens Actual: assertion fails.
[QC Description]
If you execute code like "aListBox.Items.InsertObject(-1, 'SomeString', aObject)" the string 'SomeString' is
happily inserted to the list box but the object is lost.
The cause for this is ; TListBoxStrings.Insert does not test for a condition of Index being -1, since it is perfectly
legal to send LB_INSERTSTRING with -1. But TListBoxStrings.PutObject tests if Index is -1 and silently exits if it
is. (It is still legal to send LB_SETITEMDATA with -1, but I think the programmer would have thought this would
have an undesirable outcome).
The correct approach should be to override InsertObject and make the "-1" test there, or, allow "-1" to be Item
Index as there is nothing wrong with this with WinApi.
It is not common to call InsertObject with -1 but it occurs with drag-drop list boxes if you drop an item too near to
the bottom of the box.
Note: Hunting for bugs like this is really difficult as it really occurs very infrequently and seemingly randomly,
_and_ however you are prepared for error logs and else you won't have any logs of mouse coordinates or
visuals when the exception log is posted to you. This one has haunted me a little too long.
More Info:
I further pursued the matter, and found out that the reason of the bug is exactly as I commented to Mr. Tomohiro
Takahashi. To duplicate it here;
While you are dragging an object, the existence of a valid drop target is determined by controls.DragFindTarget.
DragFindTarget calls DragFindWindow, and it calls "WindowFromPoint" with the current mouse coordinates. So
if you have a WinControl under the pointer, you have a valid Target.
Since we are inserting an object to a ListBox we call ItemAtPos function of the ListBox to find out the position to
insert. We pass False to Existing, since -the documentation states"If Existing is set to false, ItemAtPos returns the index of the last item in the list box plus one."
Even if there are no items in the box it will return 0. Fine, we can insert there.
TCustomListBox.ItemAtPos executes a test in the very beginning of the procedure and returns -1 if the test fails.
This test is "if PtInRect(ClientRect, Pos) then". Notice the "ClientRect" in the test. A standard List Box has *2*
pixels width/height of NonClientArea at its edges. (This is on W2K, other OS or theming can slightly change the
area).
So it is perfectly possible, though rare, a user at times can drop his item at the very edge; where we have a valid
Target, but ItemAtPos, despite the documentation and design, returns -1. And, when we execute
ListBox.Items.InsertObject, we have our string inserted, but not our *Object*.
I have attached a project which clearly demonstrates the bug at large. (Please don't run it in a VM. At least
Virtual PC does seem to override the default mouse behaviour.)
Regards.

I think The result type of TCustomWinSocket.ReceiveText should be 'AnsiString', but declared as 'string'.
ReceiveText sets result string length by internally called ReceiveBuf, and ReceiveBuf returns byte length, not
Char length.
By this wrong type of ReceiveText result, the data read from ReceiveText is broken.
In case of SendText, the param type is AnsiString, there seems no problem.

VCL\Win 32 Controls\TPageControl
Description:
Steps:
TLabel is not painted on a themed, double-buffered TTabSheet in Vista
1) Create a new project, make runtime themes enabled in Project Options. 2) Add a TPageControl on the form.
3) Add one TTabSheet to the page control. Set TTabSheet.DoubleBuffered := True; 4) Drop TLabel on the
TTabSheet. TLabel will not be visible. Setting DoubleBuffered to False makes the label visible again.
[QC Description]
In Windows Vista, when enabling runtime themes in a project, all labels placed directly on a TTabSheet control
which has DoubleBuffered property set to True will be invisible.
I'm not an expert on internals of VCL, but looking at WM_PAINT handler of TWinControl, there is the following
code:
if not FDoubleBuffered or (Message.DC <> 0) then
...
else
begin
if DwmCompositionEnabled then
begin
// Use DWM methods when in Vista
DC := BeginPaint(Handle, PS);
try
PaintBuffer := BeginBufferedPaint(DC, PS.rcPaint, BPBF_COMPOSITED, nil, MemDC);
if PaintBuffer <> 0 then
try
Perform(WM_ERASEBKGND, MemDC, MemDC);
Perform(WM_PRINTCLIENT, MemDC, PRF_CLIENT);
if not (Self is TCustomForm) then
BufferedPaintMakeOpaque(PaintBuffer, PS.rcPaint);
finally
EndBufferedPaint(PaintBuffer, True);
end;
finally
EndPaint(Handle, PS);
end;
end
else
begin
// Draw in memory when not in Vista
// ..
Perform(WM_ERASEBKGND, MemDC, MemDC);
Message.DC := MemDC;
WMPaint(Message);
Message.DC := 0;
// ...
end;
end;
So when not in Vista, WM_ERASEBKGRD and WM_PAINT messages are sent while in other OSes
WM_ERASEBKGRD and WM_PRINTCLIENT are sent.
As I understand, child controls are drawn in WM_PAINT, not in WM_PRINTCLIENT so TLabel is never drawn.

Description:
Steps:
TParam.GetDataSize return incorrect value for Blob data type
Run the following in Delphi 2009:
[QC Description]
If we have a TParam object (Q) of ftBlob and we assign a string to it:
Q.Value := 'TEST';
Invoke Q.GetDataSize will return 4. But if invoke TParams.AsBytes it would return a TBytes of length 8.
This create a problem in procedure SetQueryProcParams of SqlExpr.pas:
procedure SetQueryProcParams(const Sender: TSQLConnection;
const Command: TDBXCommand; const Params: TParams; ProcParams: TList = nil);
begin
...
ftBlob, ftGraphic..ftTypedBinary,ftOraBlob,ftOraClob:
begin
Buffer := TDBByteBuffer.Create(Param.GetDataSize);
Buffer.Append(Param.AsBytes);
ExtractedBytes := Buffer.GetBytes;
Value.SetDynamicBytes(0, ExtractedBytes, 0, Length(ExtractedBytes));
end;
...
end;
var P: TParams;
Q: TParam;
i, j: integer;
begin
P := TParams.Create;
try
Q := P.CreateParam(ftBlob, 'Blob', ptInput);
Q.Value := 'TEST';
i := Q.GetDataSize;
j := Length(Q.AsBytes);
finally
P.Free;
end;
end;
variable i return 4
variable j return 8
Invoke "Buffer.Append(Param.AsBytes)" will always raise ERangeError exception with message 'CheckSpace'.
The reason is simple. Buffer is allocated 4 bytes of space but we later append 8 bytes of data to it and thus the
ERangeError was raised.
I am not sure if this is a bug or it is by design. Should we let the program decide the encoding of string data store
into a blob field? If we let the program decide, the blob field data may not accessible by legacy program that
always treat the blob field string data as ANSI encoding.

Expected: The Chinese text is accepted and displays correctly. Actual: The Chinese characters are replaced

Attempting to type any characters outside the active codepage into a UTF8String property in the object inspector
corrupts the text, and replaces the characters with question marks.
It appears that the RTL is unable to stream UTF8String published properties to and from form resources.

runs as expected Add DbGrids to main form uses clause Project now crashes with EAccessViolation 'at
address 0040D3A0 in module Project1.exe. Read of address 006B0073'
[QC Description]
Adding a TRibbon control (no panels/groups etc) to a single form application that contains an ActionManager
component raises an access violation exception when attempting to execute a rave report.
The error may also be dependent on the presence of a network printer (in my case called: 'LaserJet 1329 on
ARGSRV1'). I have seen other reports relating to Rave failures and printers (mainly concerning a crash when
trying to invoke the rave editor). However, this problem can be rectified by removing the ribbon component and
the ribbon units from the uses clause.
NB. Just deleting the Ribbon and setting the ActionManager style back to standard does not remove the
problem. To remove the problem, the Ribbon and RibbonLunaStyleActnCtrls units must also be removed from
the uses clause.
Also: a simple application with only a single ribbon control, a rave project component and a button (to action the
report) will allow the rave report to execute correctly, even if the network printer is in place. However, if I add
DBGrids into the main form uses clause, the same access violation exception occurs.
It seems to me that a conflict is occurring at a fairly fundamental level.

Drop a TDatabase, TTable and a TButton on a form Set the TDatabse DatabaseName to 'LocalDB' Set the

customer.db In the Buttons OnClick event add this code Table1.Open; ShowMessage(Database1.Directory);
Run it and click the button. The table is opened but the message dialog (Ctrl C copied to paste here) shows -------------------------- Project1 --------------------------- ??????????????????????????????????????????????????"
<< note: this was originally chinese, wingdings type characters --------------------------- OK --------------------------- If
you also add an AfterConnect event handler on the TDatabase and add the following code
Database1.Directory := 'C:\Program Files\Common Files\CodeGear Shared\Data'; You still get a similar result
as before when clicking the button So you can't read or write the Directory property. Note: After initial
submission of this report, the strange characters (some chinese, wingdings type stuff etc.) changed to all
question marks
[QC Description]
There are string handling issues with TDatabase GetDirectory and SetDirectory.
Attempting to read the Directory property returns what appears to be an uninitialized string of characters.
Setting the property to a known path and subsequently reading it back gives the same obscure results.

Description:
Steps:
Error opening table when field has a DefaultExpression
I tried the following The GetPAnsiChar is as follows function GetPAnsiChar(const S: string): PAnsiChar; begin if
S <> '' then Result := PAnsiChar(AnsiString(S)) else Result := ''; end; But if I replace the original line with this:
StrCopy(ADataSources.szSQLExprImport, PAnsiChar(AnsiString(Field.DefaultExpression))); Then the error
doesn't occur any more and ADataSources.szSQLExprImport always contains a valid value (FALSE in my
case) Now, this looks to me to be doing exactly the same thing but I think something is going wrong when
calling GetPAnsiChar instead which causes it to return the corrupt string. I've spent ages trying to replicate it
outside the main application but cannot do so. It only raises the error when I run the big application with lots of
tables/queries open If pushed I could probably send you a screen vid of the situation happening in the
debugger.
[QC Description]
There seems to be an issue with the GetDefaultExpression function in the TBDEDataSet.ConstraintCallBack
function in the DBTables unit.
I was getting the following error when opening the TTable which has persistent fields and two of them
(TBooleanFields) have a DefaultExpression set to FALSE.
"Preparation of field default failed.
Token not found.
Token: €€€€€€Ì << these look like euro symbols and accented characters
Line Number: 1"
I traced into the above function and found that after calling this line:
StrCopy(ADataSources.szSQLExprImport, GetPAnsiChar(Field.DefaultExpression));
The value in ADataSources.szSQLExprImport is all corrupt characters.
If I remove the DefaultExpressions from the two fields, the table opens without error.
I cannot replicate this in a simple test project but within a large application with several tables, queries,
datamodules, etc. the error happens every time. The strange characters can vary each time though.

At the top of the page the header contains the following text:

I expected to find something along the lines of:
"StartsStr determines if the substring ASubText begins the string AText using a case sensitive algorithm. If
ASubText matches the beginning of AText, the result is true, otherwise it is false."
That would be consistent with the documentation for StartsText. (I just copy and pasted it and changed case

This function should return 1 but instead returns 0: function ValBlankStringBug:Integer; var N:Double;

[QC Description]
The method System.Val should set the Code output parameter to 1 if the supplied string is empty.
However since Unicode was introduced (Delphi 2009) the floating point version of Val now sets the code
parameter to 0 - implying that the string is a valid number, which it is not.
I've marked this type 'B' because it has caused us dozens of bugs, including databases returning invalid reports
because the user input was misinterpreted.
I believe that the bug is in _ValExt in System.pas line 9252 (just after @@Empty label).

Description:
Steps:
When adding a TCategoryPanel by using CreatePanel to a TCategoryPanelGroup it is inserted in the wrong
position
1) Create e new VCL application 2) Drop a TCategoryPanelGroup in the form 3) Add three or more
CategoryPanels (rightclick -> New Panel) 4) Add a button and add the following code. procedure
TForm1.Button1Click(Sender: TObject); var CategoryPanel: TCategoryPanel; begin CategoryPanel :=
CategoryPanelGroup1.CreatePanel(Self) as TCategoryPanel; CategoryPanel.Caption := 'CategoryPanel' +
IntToStr(CategoryPanelGroup1.Panels.Count); end; 5) Compile and run and press the button Actual result:
CategoryPanel1 CategoryPanel2 CategoryPanel4 CategoryPanel3 Expected result: CategoryPanel1
CategoryPanel2 CategoryPanel3 CategoryPanel4
[QC Description]
When adding a TCategoryPanel by using CreatePanel to a TCategoryPanelGroup one expects that the newly
created is added to the end
(below) the already existing panels, instead it is inserted before the last panel.
Further more there is a check in that function ...
10574: if FPanels.Count = 0 then
... which is pointless because a Panel was just added to the list and Count will always be > 0.
A corrected version should look something like this:
procedure TCustomCategoryPanelGroup.InsertPanel(Panel: TCustomCategoryPanel);
var
LPanel: TCustomCategoryPanel;
begin
FPanels.Add(Panel);
Panel.FPanelGroup := Self;
if FPanels.Count = 1 then // Modified was 0
Panel.Top := 0
else
begin
LPanel := TCustomCategoryPanel(FPanels[FPanels.Count - 2]); // Modified was [FPanels.Count - 1]
Panel.Top := LPanel.Top + LPanel.Height + 1;
end;
Panel.Left := 0;
Panel.Align := alTop;
Panel.Alignment := FHeaderAlignment;
if not (csLoading in ComponentState) then
AutoScrollInView(Panel);
end;
[Edit1]
Note that the current sort/compare function inverts the list of CategoryPanels.
{$IF DEFINED(CLR)}
function ComparePanels(Item1, Item2: TObject): Integer;
{$ELSE}
function ComparePanels(Item1, Item2: Pointer): Integer;
{$IFEND}
begin
Result := TCustomCategoryPanel(Item2).Top - TCustomCategoryPanel(Item1).Top;
if Result > 0 then
TCustomCategoryPanel(Item2).PanelGroup.FReorderPanels := True;
end;
To make the above change of InsertPanel() more reliable the "compare line" should be changed to ...
Result := TCustomCategoryPanel(Item1).Top - TCustomCategoryPanel(Item2).Top;
... first reaction is that the following line should also be changed to ...
if Result < 0 then
... but without further testing that complete statement looks a little strange in a QuickSort algorithm ;-)

The left of the first character is often clipped. The error is generally only one pixel, but it can be a problem
especially with charcters with diacriticals.
The problem is also present in TBitBtn.
A standard capital T in Tahoma at 8 point is visibly assymetrical. A character that demonstrates the issue well is
a lower case latin small letter I with diaeresis (U+00EF). The left hand dot above the vertical line is generally lost.
The effect is visible with or without themes.
The code measures the required size for the text using the OS DrawText call, and uses the returned rectangle to
set the size of a clipping rectangle when displaying it.
It seems the OS clips the text. From the SDK documentation for DrawText: "Note that text with significant
overhang may be clipped, for example, an initial "W" in the text string or text that is in italics." There is no
matching comment in DrawThemeTextEx which is also used in some circumstances, but it seems to have the
same issues as DrawText.
Standard Windows buttons do not suffer the effect.
Possible solutions would be to expand the measured rectangle slightly or to add a DT_NOCLIP flag in the
DoDrawText calls in TButtonGlyph.DrawButtonText (Buttons.pas).
The problem was present back in Delphi 7, but was not generally seen because it depends on the font. D7
normally uses MS Sans Serif - and the fault does not show with that, but changing the font to Tahoma makes it
perform just the same as current versions of Delphi.

Steps:
Easy to fix in VCL: Using wrongly sized TSmallIntField in stead of TIntegerField causes memory overwrite
TDBXWeaverBugsSuite.Native.DB.Test.exe connection=ibconnection -s:TestRaid_267657
-or-
[QC Description]
This QC shows how calling IsNull on a the result field of the query below can result in a memory overwrite.
1. Compile and run the attached application.
2. Click the button "Bad IsNull"
The normal memory manager does not detect this, so you will see spurious artifacts in your applications.
Only the FastMM memory manager in full debug mode detects it reliably.
Expected: no error
This bug occurs frequently when the datasizes of the underlying DB have changed, but the persistent fields in
the application have not yet been corrected yet.
As the IDE has no way of automatically correcting the datatypes of persistent fields, and this error is hard to
detect, I have rated it quite high to fix.
The attached application reproduces the issue. It includes FastMM as that is the only way to reproduce it.
Actual: FastMM has detected an error during a FreeMem operation. The block footer has been corrupted.
Notes:
A. the buttons "Good Value" and "Good IsNull" are to demonstrate that using a persistent TIntegerField works
fine
The queries in the application accesses the employee.gdb demo database that ships with any Interbase version: B. the button "Bad Value" is to demonstrate that using a persistent TSmallintField for obtaining the Value works
fine too
Select Max(SALES.QTY_ORDERED)
From SALES
The bug can be reproduced with any query returning an integer field; this particular example is just to make it
easy to reproduce.
The bug manifests itself when you use Persistent Fields that are of the wrong size.
The expected behaviour is to get some kind of size warning, or an overflow.
The actual behaviour is a memory overwrite that can be detected by FastMM.
The solution to resolve the issue is simple
The accompanying application contains two queries:
BadSQLQuery and GoodSQLQuery both contain persistent fields:
object BadSQLQueryMAX: TSmallintField
FieldName = 'MAX'
end
object GoodSQLQueryMAX: TIntegerField
FieldName = 'MAX'
end
Behaviour:
- obtaining BadSQLQueryMAX.Value: value will overflow
- obtaining BadSQLQueryMAX.IsNull: memory overwrite occurs
The cause of the memory overwrite is that:
- TField.GetIsNull calls GetData(nil)
- The actual field now allocates a buffer that is too short
- The actual TDataSet now overwrites this buffer with a value of the native size
Obtaining BadSQLQueryMAX.Value does not generate a memory overwrite because:
- TSmallintField is derived from TIntegerField
- TIntegerField.GetAsInteger calls GetValue(Result)
- the Result os if size LongInt which is large enough to hold the result
Hence the proposed workaround is to introduce TIntegerField.GetIsNull that
mimics TIntegerField.GetAsInteger behaviour:
{ Proposed workaround: add the below GetIsNull method to TIntegerField
//MMWIN:MEMBERSCOPY
unit _MM_Copy_Buffer_;
interface
type
TIntegerField = class(TNumericField)
protected
function GetIsNull: Boolean; override;
end;
implementation
function TIntegerField.GetIsNull: Boolean;
var
Dummy: LongInt;
begin
Dummy := -1;
Result := not GetValue(Dummy);
end;
end.

1. Open the attached project 2. Start the project (This will copy '12.12.08' into the clipboard) 3. Click into the
FLD_DATE field in the grid (show inplace editor) 4. Paste the clipboard text into the control by pressing Ctrl+V
5. Use TAB, ENTER or the mouse to leave the edit mode Expected: '12.12.08' is now in the field. Actual: The
field is still empty.
[QC Description]
The DBGrid InplaceEditor ignores text that was pasted from the clipboard if the field has an EditMask.
This is because the TCustomMaskEdit overrides the WM_PASTE (and WM_CUT) message handler and if as
mask is specified, the default handler isn't called. The default handler sends a WM_COMMAND(EN_CHANGE)
to the parent but without calling the default handler this message isn't sent to the DBGrid and the content of the
edit is never copied to the internal InplaceEdit text field.

[QC Description]
If a TStreamReader is created with an encoding that does not
match the encoding of the stream, TStreamReader hangs in an
endless loop.
I haven't tested if the crash also happens if a stream is broken.
SR := TStreamReader.Create(MS, TEncoding.UTF8);
end; MS.Position := 0; SR := TStreamReader.Create(MS, TEncoding.UTF8); try while not SR.EndOfStream do begin S := SR.ReadLine; if J = 4 then if S = T
then Pass := False; if (S <> T) and (J <> 4) then Pass := False; end; finally SR.Free; end; if Pass then Writeln('PASS ' + Encoding.ClassName + ' ' + IfThen(J
< 4, 'MyString', 'MyString2')) else Writeln('FAIL ' + Encoding.ClassName + ' ' + IfThen(J < 4, 'MyString', 'MyString2')); finally MS.Free; end; except on E:
Exception do WriteLn('FAIL - Exception=', E.ClassName, '/', E.Message); end; end; end.
It also hangs when reading a Unicode stream with DetectBom =
False:
SR := TStreamReader.Create(MS, False);
Try changing MyString in the steps to:
MyString2 = #$1FFFF + mystring;
This does not hang indefinitely, but takes very long to read. This is
probably invalid for UTF8, but it should come to that conclusion
much sooner.

Possible buffer overrun in GetDefaultPrinter
procedure TPrinter.SetToDefaultPrinter; var [...] DefaultPrinter: array[0..1023] of Char; [...] I := SizeOf
(DefaultPrinter); GetDefaultPrinter(DefaultPrinter, I); Possible solution: I := Length(DefaultPrinter); if not
GetDefaultPrinter(DefaultPrinter, I) then FillChar(DefaultPrinter, SizeOf(DefaultPrinter), #0);
[QC Description]
There is a possible buffer overrun in the call to GetDefaultPrinter. Apart from memory corruption, this could crash
the application with a DEP (data execution prevention) error.
GetDefaultPrinter expects the Length of the buffer in TChars. The current implementation is passing the *size* of
the buffer.
Therefore change the following line in Printers.pas
I := SizeOf(DefaultPrinter);
to
I := Length(DefaultPrinter);
Also the result of DefaultPrinter must be checked. If the function fails, the content of DefaultPrinter is undefined.
In this case there is not even a guarantee that there is a terminating #0 character. DefaultPrinter returns an error
if there is no printer installed (as expected).
[Update]
The documentation of GetDefaultPrinter in the Windows SDK says that the size is in "characters". This would
have been clearer if it had said "tchars", because that is what the function expects. A little test confirms that
characters refers to tchars indeed.

TVarData.VString interpreted as UnicodeString, while it contains a pointer to an AnsiString
Search in the RTL/VCL code for all 'VString' occurances. Notice that in Variant.pas all TVarData.VString are
cast to an AnsiString. Now notice that DBCommon (and other units) do a cast to 'string', which effectively
means a cast to 'UnicodeString'.
[QC Description]
A search in DBCommon for the symbol 'VString' (a member of TVarData), results in 8 occurances of this
construct : "string(TVarData(Value).VString)".
Since 'string' now means UnicodeString, this construct interprets an AnsiString as UnicodeString, without any
compiler magic in between.
Possibly the new string-header helps preventing errors, but at the very least this is a syntactic error.
PS: Don't mix this up with TVarRec.VString: PShortString, it's TVarData.VString: Pointer that's handled wrong.

[QC Description]
It seems that the compiler accepts every value for i in ST(i) in x87 instructions although Intel's manual clearly
says that i can be between 0 and 7. This information can be found in
http://download.intel.com/design/processor/manuals/253666.pdf
Section 3.1.1.1 "Opcode Column in the Instruction Summary Table"
+i - A number used in floating-point instructions when one of the operands is ST(i) from the FPU register stack.
The number i (which can range from 0 to 7) is added to the hexadecimal byte given at the left of the plus sign to
form a single opcode byte.

Database\Data Aware Controls\TDBEdit
Description:
Steps:
Data aware controls are not respecting the TDataSource AutoEdit property
Run the attached example and see that you can enter text and get the errors.
[QC Description]
When a datasource has it's AutoEdit property set to false, various edit controls (TDBMemo, TDBEdit, etc) are not
respecting
the AutoEdit setting.
With AutoEdit = false:
Upon entering text (which they shouldn't allow you to do without first going into edit mode), they do not put the
dataset
into
edit state (as expected) but they do allow you to enter text (not expected). Then, moving focus to another control
raises a
'Dataset not in edit or insert mode' exception.
I've tried the attached example code under D2007 and it behaves as expected.

QC Entry 71082
-sTest_AS_DataRequest.
Server:
Setup a basic DataSnap server with a TSQLConnection, TSQLDataSet, and TDataSetProvider (and
TDSServer, TDSServerClass, TDSTCPServerTranspot for DataSnap 2009 connectivity).
Add an event handler for TDataSetProvider.OnDataRequest to do something simple, like setting the result to
the input parameter.
Client:
Setup a basic DataSnap client with a TSQLConnection, TDSProviderConnection, and TClientDataSet. Hook
everything up so the data set gets data from the data set in the server.
Call TClientDataSet.DataRequest. The server will throw a variant exception.
Cause:
The problem appears to be in DSServer.pas:TDSProviderDataModuleAdapter.AS_DataRequest. The local
Data: OleVariant variable is being assigned DataStream.AsVariant. The problem is that DataStream is already
an OleVariant, and Variants evidently don't know how to convert themselves to a Variant. :)
Seriously though, this results in Variants.pas:_DispInvoke being called against the DataStream variant.
_DispInvoke doesn't know how to handle basic variant types (like varInteger and VarOleStr), so
FindCustomVariantType fails to find a handler, and VarInvalidOp is called.
The problem is solved by changing this line in DSServer.pas from:
Data := DataStream.AsVariant;
to
Data := DataStream;
Or, alternatively, remove the local Data variable completely and change this line:
Result := FProviderDataModule.Providers[ProviderName].DataRequest(Data);
to
Result := FProviderDataModule.Providers[ProviderName].DataRequest(DataStream);
I did the latter and saved a copy in my project folder, rebuilt the server, and the error was resolved.

Fail when assign XML string contain unicode character to ClientDataSet

[QC Description]
I create a TClientDataSet instance in Delphi 2009:
Run the following code or extract from attachment:
var D: TClientDataset;
Y: string;
begin
D := TClientDataSet.Create(Self);
var D: TClientDataset;
Y, Z: string;
begin
D := TClientDataSet.Create(Self);
D.FieldDefs.Add('F1', ftWideString, 20);
D.CreateDataSet;
D.AppendRecord(['test ??']);
Y := D.XMLData;
end;
D.FieldDefs.Add('F1', ftWideString, 20);
D.CreateDataSet;
D.AppendRecord(['test ??']);
Memo1.Lines.Add(D.Fields[0].AsString);
Memo1.Lines.Add('');
Y := D.XMLData;
Memo1.Lines.Add(Y);
The string field F1 has value of "test ??" and variable Y will content the following XML string:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <DATAPACKET
Version="2.0"><METADATA><FIELDS><FIELD attrname="F1" fieldtype="string.uni"
WIDTH="40"/></FIELDS><PARAMS CHANGE_LOG="1 0 4"/></METADATA><ROWDATA><ROW
RowState="4" F1="test &# 20013;&# 22830;"/></ROWDATA></DATAPACKET>
Z := FormatXMLData(Y);
Memo1.Lines.Add(Z);
D.Close;
Please note that the string is using ampersand entity presentation for 2 unicode character (I purpose put a space D.XMLData := Z;
between &# and numeric code point or else browser will interpret it as unicode character.
Memo1.Lines.Add(D.Fields[0].AsString);
I then use FormatXMLData to tidy up the XML:
D.Free;
Z := FormatXMLData(Y);
end;
Variable Z contain:
<?xml version="1.0" standalone="yes"?>
<DATAPACKET Version="2.0">
<METADATA>
<FIELDS>
<FIELD attrname="F1" fieldtype="string.uni" WIDTH="40"/>
</FIELDS>
<PARAMS CHANGE_LOG="1 0 4"/>
</METADATA>
<ROWDATA>
<ROW RowState="4" F1="test ??"/>
</ROWDATA>
</DATAPACKET>
FormatXMLData has convert the ampersand entity to unicode character. So far so good.
When I re-assign the XML back to TClientDataset instance, the string field value isn't the value I define at first:
"test ä¸å¤®"

space must then be replaced manually for the code to compile. --- E.g. 2) Suppose the template name is "fan"
[QC Description]
and that it expands to "FreeAndNil": Suppose that before Ctrl+Space you have: fan|(ObjectReference); After
When Ctrl+Space is used to expand a template name into a template, the character following the template name Ctrl+Space you get: FreeAndNilObjectReference); rather than: FreeAndNil(ObjectReference); This lost
disappears.
semicolon must then be replaced manually for the code to compile.

IDE\ToDoList
Description:
Steps:
ToDo list does not display todo comment if a source code is ANSI, and todo commnet contains a character
outside us-ascii.
Open attached project file.
IDE loads Project1(.pas) file into editor.
Open ToDo list.
All accented character, copyright mark and DBCS characters have same problem.
You will find three ToDo list. If not, check "Current project source files" in "Filter To-Do List" dialog.
Especially, It is too important for DBCS user. They (and I) usually use DBCS character in ToDO comment.
A ToDo item in Unit1_1252.pas in To-Do List is
"An encoding is ANSI....."
Double click this item. Unit1_1252.pas is loaded.
You can find actual ToDo list is started with Cipyright mark.
If you change the text in Unit1_1252.pas, ToDo list will display correct comment.

Form resizing issue
Create a new form. Set MaxWidth to 300 for example. Try to resize form from left side. After reaching maximum
width the resizing stops but the form starts to move!
[QC Description]
I always see that Constraints does not apply completely to forms.
I found that there is useless variable in WMGetMinMaxInfo message method of TCustomForm.
The variable named FSizeChanging and used in line 5911. This variable is not used or assigned in any other
place.
After removing this variable from that condition in line 5911 and then replacing the new compiled Dcu, the

If there are two ClientDataSets connected through a DataSetProvider (The second ClientDataSet is connected

gets distorted in the second ClientDataSet.

Faulty handling of FModified in XMLDoc.pas
Run the attached application. Observe the caption doesn't reflect the correct XML.
[QC Description]
Local variable FModified is an integer that is incremented for each
modification.
In SaveToXMLStrings FModified is compared with FXMLStrRead to see if the
xml text property should be refreshed. (FModified <> FXMLStrRead)
SaveToXMLStrings sets FXMLStrRead := FModified when it is done.
So FXMLStrRead variable retains the value for FModified when the xml
text property was last refreshed.
When you save the document to file FModified is reset to 0 and starts to
count upwards again for each modification.
This means that when FModified again reaches the exact same value that
FXMLStrRead has, the xml property will not be refreshed in SaveToXMLStrings.

Steps:
Unloading DLL breaks exception handling in host application
Demonstrated in the attached projects.
[QC Description]
When a Delphi host application raises an exception, and then unloads a Delphi DLL within a nested exception
handling clause (Try ... Finally ... Except), the exception object gets "hijacked" and destroyed by the DLL
unloading procedure, causing the host application to crash.
(JJS: The crash described does not occur when using the IDE. The executable should be run on its own or in
the IDE via "Run without Debugging")
For example, the following program crashes at step 4 with an access violation:
Try
1. Load the DLL;
Try
2. Raise Exception.Create('Ooops!');
Finally
3. Unload the DLL;
End
Except
On E:Exception do
4. Print Exception message;
End
The problem seems to be caused by the "exception stack cleaning" code in the Halt0 procedure of the
System.pas. This code blindly acquires and frees all outstanding exceptions. When executed during the DLL
unloading, it frees the exception object prematurely, leaving the host application in step 4 accessing a piece of
freed memory.
The suspect code segment is also referred to in QC#72439.
The problem only happens when building DLL and host application with packages.

TClientDataset server side TWideStringField curruption
-or-
[QC Description]
In D2009, we have a multitier application where we use TDatasetProvider to
exchange data to a client-side TClientDataset.
The server datasets is of different types, e.g. TADOQuery, TADOTable, but
also of type TClientDataset (we build datasets in code server side and
exchange it with the client). If he server side data set is of type
TClientDataset there are problems with unicode strings.
See the attached application
The problem occurs when a TWideStringField is used in the server side
TClientDataset. The unicode string is broken when sent from the server to
the client. I believe it happens in the routine that builds the data packet
on the server side.

TestChangeParams, open the popup menu and call "Refactor"\"Parameter aendern" (english: "Change
params") - see there is for exam. an entry for the P4 parameter in the parameter list and it's type "const" (and
not "Konst") - press the "Hinzufuegen" (english: "Add") button - have a look at the bottom of the dialog at the
"Parametertyp" (english: "Parameter Type") groupbox expected: Value | Var | Out | Const actual: Wert | Var |
Aus | Konst (see image ChangeParams1.png) - have a look at the top of the dialog at the caption above the
listview expected: Uebereinstimmende Ergebnisse: actual: UebereinstimmendeErgebnisse: (missing space
between Uebereinstimmende and Ergebnisse; see purple line on image ChangeParams1.png) - enter a
parameter name (P5) and data type and select "Wert" (english: "Value") as parameter type - press OK - have a
look at the parameter list again and see that the type is "value" and not "Wert" (see image
ChangeParams2.png)
[QC Description]
I recently used the "Change Parameters" refactoring in the german version and have seen that the parameter
type is translated in the "Add Parameter"/"Edit Parameter" dialog.
In the english version the values for "Parameter Type" are
Value | Var | Out | Const
and in the german version it is translated to
Wert | Var | Aus | Konst
which is nonsense and differs from the parameter type names in the main "Change Parameters" dialog.
BTW, there seems to be a missing space in the translation of "Matching Results" in the "Add Parameter" dialog -
the text is obviously "UebereinstimmendeErgebnisse" and not "...de Ergebnisse".

IBSQLMonitor Char/AnsiChar buffer mismatch
Any use of TSQLMonitor will demonstrate that the text in FBuffer is incorrect.
[QC Description]
The use of FBufferSize and FBuffer in TWriterThread.WriteToBuffer and TReaderThread.ReadSQLData does
not handle wide characters properly.
My solution was:
1) Change all PAnsiChar to PByte in IBSQLMonitor.pas
2) Change TWriterThread.WriteToBuffer to use a new cMaxChars local constant
procedure TWriterThread.WriteToBuffer;
const
cMaxChars = cMaxBufferSize div SizeOf(Char); // tpm
var
i, len: Integer;
Text : String;
begin
Lock;
try
{ If there are no monitors throw out the message
The alternative is to have messages queue up until a
monitor is ready.}
if FMonitorCount^ = 0 then
FMsgs.Remove(FMsgs[0])
else
begin
Text := TTraceObject(FMsgs[0]).FMsg;
i := 1;
len := Length(Text);
while (len > 0) do begin
BeginWrite;
try
FTraceDataType^ := Integer(TTraceObject(FMsgs[0]).FDataType);
FTimeStamp^ := TTraceObject(FMsgs[0]).FTimeStamp;
FBufferSize^ := Min(len, cMaxChars) * SizeOf(Char); // tpm
Move(Text[i], FBuffer[0], FBufferSize^);
Inc(i, cMaxChars); // tpm
Dec(len, cMaxChars); // tpm
finally
EndWrite;
end;
end;
FMsgs.Remove(FMsgs[0]);
end;
finally
Unlock;
end;
end;
3) Change TReaderThread.ReadSQLData to use SizeOf(Char) as follows:
procedure TReaderThread.ReadSQLData;
begin
st.FMsg := ''; {do not localize}
BeginRead;
if not bDone then
try
SetString(st.FMsg, PChar(FBuffer), FBufferSize^ div SizeOf(Char)); // tpm
st.FDataType := TTraceFlag(FTraceDataType^);
st.FTimeStamp := TDateTime(FTimeStamp^);

EndRead;

CTRL+ALT+B) - put a breakpoint on line 6 ("Writeln...") and you should now see a breakpoint for this line in the

actual: the breakpoint is still there and the Action is now empty (was "Break" and the action change is a feature

[QC Description]
I tried to remove a breakpoint with the OTA by calling IOTABreakpoint40.Destruct, but that does just nothing.
The comment above the Destruct method is
{ Call this to destroy the object }
It doesn't say explicitly that it removes the breakpoint, but on the other hand I don't see any real reason why an
OTA user should destroy the breakpoint. (...interface...ref-counted...)
A more straightforward way to remove a breakpoint would a "RemoveBreakpoint" method in
IOTADebuggerServices.

Bug in TParam.GetAsAnsiString
or
[QC Description]
After assigning a UTF8 encoded string to a TParam object, the string becomes corrupted.
See attached project
TParam.GetAsAnsiString consists of the following code:
function TParam.GetAsAnsiString: AnsiString;
begin
if VarType(FData) = vtAnsiString then
Result := AnsiString(FData)
else
Result := AnsiString(GetAsString);
end;
Since FData is declared as a Variant instead of a TVarRec, the first condition is never
met. This results in UTF8 encoding being lost. To correct this issue, change the code
to:
function TParam.GetAsAnsiString: AnsiString;
begin
if VarType(FData) = varString then // Changed vtAnsiString to varString
Result := AnsiString(FData)

Cannot cast to a generic type parameter restricted as class
[QC Description]
The compile currently doesn't permit casting an object to a generic type parameter that is restricted as class:
// ----type
TFoo<T: class> = class
function Get: T;
end;
function TFoo<T>.Get: T;
begin
Result := T (TObject.Create); // E2089 Invalid typecast
end;
// ----IMHO, this is basic functionality. As an example, consider the following attempt to reduce boilerplate code:
// ----type
TOwnedCollection <TItem: TCollectionItem> = class (TOwnedCollection)
private
function GetItem(Index: Integer): TItem;
procedure SetItem(Index: Integer; Value: TItem);
public
constructor Create (AOwner: TPersistent);
function Add: TItem;
function GetEnumerator: TCollectionEnumerator <TItem>;
function Insert (Index: Integer): TItem;
property Items[Index: Integer]: TItem read GetItem write SetItem;
default;
end;
// ----How would you implement TOwnedCollection<TItem>.GetItem?
Of course, the straightforward approach is
// ----function TOwnedCollection<TItem>.GetItem(Index: Integer): TItem;
begin
Result := TItem (inherited GetItem (Index));
end;
// -----
Error: E2089 Invalid typecast

function Get: T;
end;
function TFoo<T>.Get: T;
begin
Result := T (TObject.Create); // E2089 Invalid typecast
end;
begin
end.
I ended up with this ugly workaround:
// ----function TOwnedCollection<TItem>.GetItem(Index: Integer): TItem;
var
ResultAddr: PPointer;
begin
ResultAddr := @Result;
TCollectionItem (ResultAddr^) := inherited GetItem (Index);
end;

[0,0,0])-1 ]); end;
==============================
the result of the "reproduce steps" shows the bug:
------------------------------------------------[Generic]
Full Size: [60] SizeOf(V[0]): 12 SizeOf(V[0,0]): 3
Length(V): 5 Length(V[0]): 4 Length(V[0,0]): 3
Expected Stack: 0012F3BC .. 0012F3F7

[Traditional]
Full Size: [480] SizeOf(V[0]): 96 SizeOf(V[0,0]): 24
Length(V): 5 Length(V[0]): 4 Length(V[0,0]): 3
Expected Stack: 0012F3F8 .. 0012F5D7
Actual Stack: 0012F3F8 .. 0012F5D7
==============================
We see the SizeOf(TStatic3dArray<Double>) is 60(=5*4*3) not 480(=60*8). And it reserved 60 bytes in Stack not
480. But actually it needs 480 bytes, so it may overwrite virtual memory block not reserved for it and cause
problem.
BTW, when I tried to put the type declaration into local scope of the procedure like:
type
TStatic2dArray<T> = array[0..IHigh1, 0..IHigh2, 0..IHigh3]of T;
TStatic2dArrayDouble = array[0..IHigh1, 0..IHigh2, 0..IHigh3]of Double;
....
It caused Internal Error URW1135.

intended to rely on what the SDK docs call "manual reordering": the applications code keeps track of the
header sections and their order itself and tells the control the order to user after the drag is done. In another
part of the CNNotify hander the VCL does this: NM_RELEASEDCAPTURE: if FSectionDragged then
DoSectionEndDrag; The control sends this notification after the drag has ended. FSectionDragged is the field
that stores the AllowDrag value from the event handler. If it was set to false the code that is supposed to sync
the Sections collection with the control is never called.

TComboBox "randomly" saves ItemHeight = 13 and ItemHeight = 0 into the DFM
Sadly, tteps are difficult to produce. The changin of the property is somewhat random. Sometimes, when saving
a .dfm, the value is not changed. Thre steps might be something like this: - Create a VCL forms application and
add a few TComboBoxes to the form - Save it to disk - Close the IDE - Check the value of
TComboBox.ItemHeight in the .dfm - Reopen the IDE and project - Modify the form and save it - [Some other
steps might be required here, but it is unclear] - Go back to step "Close the IDE" and recheck until the
ItemHeight value changes Maybe the issue is worse with forms involved in visual form inheritance, but maybe
not. The issue is discussed some more here: https://forums.codegear.com/thread.jspa?messageID=11734
[QC Description]
I review .dfm files for changes before checking them in, and I often see a form with a TComboBox ItemHeight
property changing from 13 to 0 and back to 13 over the course of a few days without actually changing that
property (or any property on the combobox). The problem happens under both XP and Vista and has been
happening since at least Delphi 2007.
The reason might be quoted here:
"In the VCL source files, FItemHeight is set to "16" in the constructor
(TCustomComboBox.Create), but the property's read method retrieves the
ItemHeight by performing CB_GETITEMHEIGHT windows message:
function TCustomComboBox.GetItemHt: Integer;
begin
if FStyle in [csOwnerDrawFixed, csOwnerDrawVariable] then
Result := FItemHeight
else
Result := Perform(CB_GETITEMHEIGHT, 0, 0);
end;
Looks like this call sometimes returns "0", which is then saved to the
dfm file :-("

dbx3 drivers receive wrong datatype when fetching data
- add a SQLConnection to a dbx3 driver - add a TSQLquery that tries to retrieve an INTEGER datatype from
the database - set the TSQLQuery to active - driver receives a request for a fldFLOAT instead of a fldINT32
[QC Description]
If I'm using a dbx3 driver in Weaver (build 3417) datatypes do not seem
to be mapped to the correct functions in my dbx3 driver via dbxadapter.dll for example if I try to retrieve a INTEGER value from the database, the
getDouble routine in my driver is called. This all worked fine in D2009.
Is there a wrong mapping introduced in the new dbxadapter.dll ? It
seems to me that TDBXDataTypes and TFieldType were mixed - for example
ftInteger is 6 in "driver land" and TDBXDataTypes, but 6 is ftDouble in
TFieldType.
I can trace in sqlexpr.pas that the correct value of 6 (ftInteger) is
used when DBXRow_GetFixedBytes is called, DBXRow_GetFixedBytes calls
into dbxadapter where I have no source of and then this calls the
GetDouble routine in my driver.

1. Start new delphi 2009 project (Application have to support runtime themes, tick this checkbox in the project

ex. Windows XP style -> Silver). Compile, run this application. 4. Don't close your application and switch to
windows classic style in the Appearance tab of the display properties. The result is you will not see Label1 and
BitBtn1 captions. The same for glyphs. Tested on XP, Vista, Windows 7.
[QC Description]
Themed controls like TBitBtn, TSpeedButton, TLabel and maybe other have drawing problem when switching
from themed visual style to windows classic theme.
For TBitBtn and TSpeedButton the problem is in TButtonGlyph.FThemesEnabled member that is not updated on
changing theme to classic theme.
For TLabel the problem is in TCustomLabel.Create constructor, there is only once checked ThemesEnabled and
on theme change it will not be checked and as the result we will not see label caption when switching from
Themed visual style to windows classic visual style.

Problem with filter in TClientDataSet - Delphi2009
-or[QC Description]
I would like to create filter in TclientDataset.
I have Oracle 9.0, dbExpress, table with varchar2(10) and sql query, for example "Select per_name from
personal".
If I want to create filter in Clientdataset with command 'like' it doesn't work. It returns nothing.
This feature is fully functional in Delphi 2006 and Delphi 6. It's very frustrating for me, I have to transfer
application from Delphi 2006 into Delphi 2009 (because of UNicode support), but I can't transfer it because of the
bug in Tclientdatset with command 'LIKE'.
Create table "Personal" in Oracle 9.0 with field "Per_name" varchar2(10) and put 2 records into this table. The
records are 'Smith' and 'Vagner'.
Use dbexpress technology for showing data from this table. I used Tsqldataset, TdataSETprovider,
Tclientdataset, TDataSource and TDBGrid. If you write following sql query "select per_name from personal" into
Tsqldataset and if you use TDBGrid to show data, it works. But If you want to use a filter in TclientDataSet
'(Per_name LIKE '%Smith%')', the command 'Like' doesn't work. If you use a command '(Per_name = 'Smith')',
it works.
I have all updates of Delphi 2009.

Debugger\Evaluator\Delphi
Steps:
Inspecting a string with quotes doesn't work properly
[QC Description]
When you inspect a string in the debugger, if the string has single-quote characters, the debugger doesn't show
a proper Delphi string literal -- it refuses to double-up the quotes. For example...
s := 'abc''xyz';
If we inspect s after running the above statement, the debugger shows...
'abc'xyz'
Perhaps this is "easier to read", but it causes some serious problems...
1) You can't copy-and-paste from here into a source code unit (or other tool that expects a literal).
2) It breaks the "modify" part of the Evaluate/Modify dialog -- in the sense that Evaluating the invalid string is
placed into the "New Value" edit. For example, if we evaluate "s" above, then hit the "Modify button, then s will
be trucated to just 'abc'.
3) It is ambiguous, in many cases. For example, if the Evaluate command shows the following string: 'a'#9'b'
then there are actually to real strings that could be behind this: 'a'#9'b' and 'a''#9''b'. One is a 3-character string
with a tab, the other is a 6-character string with no tab. To determine whcih one you have, you must resort to
things like taking the length of the string, or looking at the individual characters in the string.

The current implementation of interactive gestures makes it impossible for a control to receive mousemove
messages coming from Windows 7 touch if a parent control uses an interactive gesture. This is quite a problem
since TScrollingWincontrol sets TouchManager.InteractiveGestures to [idPan].
The cause is in TWinControl.WMGestureNotify():
// Find first control that wants a gesture
while (FTouchControl.Parent <> nil) and (FTouchControl.TouchManager.InteractiveGestures = []) do
FTouchControl := FTouchControl.Parent;

forwarded to the control's parent is the control implements a gesture itself.
Let's say we have a TButton which is on a TScrollBox. For some reason the button responds to igPressAndTap.
Now igPan no longer works on the button, so you can't pan the scrollbox in that area, which probably isn't what

function IsNumeric(DataType: TFieldType): Boolean; is missing support for ftLongWord and ftExtended
function TFilterExpr.PutConstant(Node: PExprNode): Integer; is missing support for ftLongWord and ftExtended.
It also might fail with ftAutoInc if it's mapped to a TUnsignedAutoIncField and a constant value > High(Integer) is
passed.
ftLongWord should map to fldUINT32
ftExtended should map to fldFLOATIEEE
procedure TExprParser.TypeCheckArithOp(Node: PExprNode); should probably be a bit more careful in the
IsNumeric() and IsNumeric() case. e.g. if one of the operands is an extended, the result should be an extended
too.
Steps:
I've rated this as a critical error because as long as this is not fixed, it's not possible to use TExprParser for any
filter which compares a ftLongWord or ftExtended against a constant value (parser bombs out with an exception,
no filter expression is being created).

Undo after search inserts superfluous navigation events
1. File -> New console application 2. Press Ctrl-F, enter a search term (e.g. a single character 'e') and search
for it multiple times with F3 3. Hit Ctrl-Z repeatedly to undo ==> instead of jumping backwards to the last 'e' with
each Ctrl-Z, the caret jumps to the top of the file inbetween each undo event. Every Ctrl-Z should simply jump
backwards and mark the preceding 'e' (exactly as in Delphi 7 and earlier). This applies when the default "group
undo" option is set; without "group undo", there is still one extra navigation event for each undo (three instead
of two) which is annoying

There are 3 failure cases.
1. Stack overflow in the StartExe/InitUnits functions.
2. An internal error.
3. Another internal error

procedure TTestRec<T>.Something;
begin
WriteLn('Bublic');
end;
var
a: TTestRec<String>;
begin
a.Something;
readln;
end.
CASE 2 -- INTERNAL COMPILE ERROR:
Just remove the class destructor from the first example and you will get an internal error like this:

CASE 2 -- COOLER INTERNAL COMPILE ERROR:
In this cace I moved the generic class definition to another unit in hopes to get past the stack overflow. This one
raises:

AV error filling out old-style object descendants
[QC Description]
Now this is yet another object bug in the implementation of legacy objects in Delphi 2009. The following code,
which worked in previous versions of Delphi, will generate an access violation:
Message=Access violation at address 004121A5 in module 'BTS270422.exe'. Read of address FFFFFFF8
program Project8;
{$APPTYPE CONSOLE}
program BTS270422;
uses

SysUtils;
{ AV error filling out old-style object descendants}
type
TTestBase=object
X: Integer;
end;
uses
Windows,
SysUtils;
{$APPTYPE CONSOLE}
type
TTestBase=object
X: Integer;
end;
type
TTest=object(TTestBase)
end;
var
T:TTest;
begin
try
ZeroMemory(@T,SizeOf(T));
except
on E:Exception do
end;
end.
Strangely enough the following code will work:
program Project8;
{$APPTYPE CONSOLE}
uses
Windows,
SysUtils;
type
end;
var
T:TTest;
begin
try
WriteLn('PASS');
except
on E:Exception do
begin
Writeln(' ClassName=', E.Classname);
end;
end;
end.
type
TTestBase=object
X: Integer;
end;
//type <-- The two objects are declared in the same ?type declaration block?.
end;
var
T:TTest;
begin
try
except
on E:Exception do
end;
end.
This however does not solve my problem as my objects are defined in several different units.
I simply don?t understand why Embarcadero (or whoever they are) simply doesn?t drop support of the legacy
object type all together or get backwards compatibility fixed ASAP. In almost every version since Delphi 2 some
behavior of the legacy objects have changed or been declared illegal and the implementation of it in Delphi 2009
seems to be one huge bug.
Too bad for an otherwise great product.

TTouchKeyboard: button margin issues
[QC Description]
- There isn't a margin between rows.
- In the Standard layout the up and down arrow keys don't align. This probably happens because the "Fn"
doesn't have a margin on its righthand side.
- There's a margin in the righthand side of the keyboard. The other sides don't have a margin.
- There's a 2 pixel margin between buttons which doesn't respond to mouse/touch clicks. It's better to avoid
these inactive areas, so the user won't wonder why the program doesn't respond to pressing buttons. Note that
the Windows 7 keyboard doesn't have inactive areas between buttons.
It would look better if all buttons had the same margin (1 pixel) on all four sides. Modifying the FindButton
function to remove the inactive areas would then be easy.

Steps:
TDirect2DCanvas can't draw 'width=1' horizontal line
- create a new VCL forms app - create a OnPaint event handler - paste the code below in the unit - run the app
- note that the Direct2D lines on the right are wider than the GDI lines on the left. Also note the the Direct2D
lines are gray, whereas the GDI lines are black. This is caused by antialiasing. - uncomment the
TDirect2DCanvas type declaration and run the app again. The lines are now identical. Rectangle() suffers from
the same problem. I think it can be fixed in a similar (but more complicated) way. --------------- code ------------------------ unit Unit1; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, Direct2D, D2D1; type TForm1 = class(TForm) procedure FormPaint(Sender: TObject); private { Private

begin RequiredState([csHandleValid, csPenValid]); p1.x := PenPos.x; p1.y := PenPos.y + 0.5; p2.x := x; p2.y :=
y + 0.5; RenderTarget.DrawLine(p1, p2, Pen.Brush.Handle, Pen.Width, Pen.StrokeStyle); PenPos := Point
(X,Y); end; } procedure TForm1.FormPaint(Sender: TObject); var LCanvas: TDirect2DCanvas; begin
Canvas.Brush.Color := clWhite; Canvas.Pen.Color := clBlack; Canvas.MoveTo(100, 50); Canvas.LineTo(200,
50); Canvas.Rectangle(100,100,200,200); LCanvas := TDirect2DCanvas.Create(Canvas, ClientRect); try
LCanvas.BeginDraw; try LCanvas.Brush.Color := clWhite; LCanvas.Pen.Color := clBlack; LCanvas.MoveTo
(204, 50); LCanvas.LineTo(304, 50); LCanvas.Rectangle(204,100,304,200); finally LCanvas.EndDraw; end;
finally LCanvas.Free; end; end; end.
[QC Description]
TDirect2DCanvas can't draw 'width=1' horizontal line because the line is antialiased, and therefor spans two
pixels. Moving the line half a pixel solves the problem.
I'd expect vertical lines to suffer from the same problem, but I haven't looked into that.

TIniFile.ReadSections passes wrong parameter to GetPrivateProfileString, corrupting heap

[QC Description]
Application crashes on startup when reading INIFiles.
See this program output indicating failure.
#1
#2 Section1=FAIL - Exception Error
Investigation shows that memory is corrupted when reading sections from an INI file.
Problematic code is here:
program TestProg;
procedure TIniFile.ReadSections(Strings: TStrings);
const
BufSize = 16384;
var
Buffer, P: PChar;
begin
GetMem(Buffer, BufSize);
/* ... */
if GetPrivateProfileString(nil, nil, nil, Buffer, BufSize,
PChar(FFileName)) <> 0 then
{$APPTYPE CONSOLE}
Problems:
1> Fixed buffer size is used, leading to data loss if actual size of file is larger.
2> GetPrivateProfileString's 5th parameter is a count of *characters* and the code is passing the number of
*bytes*. Heap corruption results.
I think the same mistake is made elsewhere in this file.
Bug #1 was supposed to be fixed by QC#35234, but it looks like that might have only fixed the "ReadSection"
function and not the "ReadSections" function.

Recently, I was looking at our Indy code to make sure it's updated for
the RTL. I noticed that IsDebuggerPresent is defined in Windows
without the stdcall conventions. Is there any reason why it isn't
being defined that way since it's a Win32 API function call?
This omission should be fixed even if it doesn't effect most code. You never know what's going to happen down

I imported (with the wsdl import wizard from Delphi 2007) a wsdl from the following location:
http://internetest.vocuslis.nl/test/services/dbs/nedapservice?wsdl
If I call the function testNedapService (returns a Boolean) I always receive false.
I installed a packet sniffer and I can see that the webservice send a true, but Delphi cannot set the true to an
object.
Also the rest of the functions don? work.
I have created a test project in Visual Studio 2005 (Visual Basic) and Eclipse (Java) and everything works fine.
So the wsdl seem to be ok.

The WMTabletQuerySystemGestureStatus screen position also suffers from the problem described in QC

Note that this can not only occur in Windows 7, but in Vista as well.

Enable debug DCUs in the project and try to debug something in system unit. See attachments for example.
[QC Description]
It is very look like debug system.dcu was compiled from another pas unit then present in source directory.
Because I very often see misplaced dots which mean the line was linked to binary, and debugging often was
unable because position of the debugger was not the real source position.
So I recompiled the system unit, replaced original one and problems has gone.

Description:
TBitmap.WriteStream selects >8bpp DIBs (unnecessarily) into HDC which (for large bitmaps) can lead to BSODs
with current nvidia drivers
[QC Description]
In TBitmap.WriteStream the following code is always called:
Canvas.RequiredState([csHandleValid]);
Save := GDICheck(SelectObject(FCanvas.FHandle, FDIBHandle));
Steps:
ColorCount := GetDIBColorTable(FCanvas.FHandle, 0, 256, Colors);
SelectObject(FCanvas.FHandle, Save);
The documentation to GetDIBColorTable states:
Remarks
The GetDIBColorTable function should be called to retrieve the color table for DIB section bitmaps that use 1, 4,
or 8 bpp. The biBitCount member of a bitmap associated BITMAPINFOHEADER structure specifies the number
of bits-per-pixel. DIB section bitmaps with a biBitCount value greater than eight do not have a color table, but
they do have associated color masks. Call the GetObject function to retrieve those color masks.
So calling GetDIBColorTable will always return 0 for any bitmap with > 8bpp, making this code useless for any
>8 bpp bitmap.
I've found that, at least with current (186.18) nVidia drivers under Windows 2008 and with large bitmaps
(6090x1682 in my case) the SelectObject call regularily fails (returns 0, but GetLastError also returns 0) and is
followed by a BSOD a couple of seconds later.
Given that the code in question is just a waste of time and resource for >8bpp bitmaps anyway, it should be
changed to:
if FDIB.dsbmih.biBitCount <= 8 then begin
Canvas.RequiredState([csHandleValid]);
Save := GDICheck(SelectObject(FCanvas.FHandle, FDIBHandle));
ColorCount := GetDIBColorTable(FCanvas.FHandle, 0, 256, Colors);
SelectObject(FCanvas.FHandle, Save);
end else
ColorCount := 0;
Not only does that prevent the BSOD (which admittedly would appear to be a driver bug that's causing kernel
mode memory overwrite), but it generally speeds up saving of TBitmap's

Steps:
Changes to package "enabled" state is not persisted
1) Select any installed designtime BPL for testing 2) Close the IDE 3) Rename or move the selected BPL so it
cannot be loaded 4) Start the IDE and wait for the "Cannot load package..." error 5) Respond "No" to disable
future attempts to load the missing BPL 6) Open Component -> Install Packages... (missing package is
unchecked) 7) Restore the BPL that was renamed or moved in step 3 8) Click the check box in Install Packages
to load the restored BPL 9) Close and restart the IDE 10) Open Install Packages dialog (restored package is
unchecked again!)
[QC Description]
There is a very annoying problem in the Component -> Install Packages... dialog that sometimes causes
changes to the "enable" check boxes in the list of packages to be lost when the IDE is closed.
This problem occurs frequently in our environment when updates to third-party packages cause package
dependencies to become broken (e.g. Package A depends on Package B and an updated version of Package B
is installed).
After a component update (e.g. installing a new version of DevExpress), the IDE emits a shower of "Cannot load
package..." errors as each broken package fails to load. Responding "No" to disable future loading of the
offending packages avoids a repeat of the same errors when a project is opened. The problem occurs when
attempting to re-enable the packages after the broken packages have been opened and re-compiled.

When you select some text in the editor and press Ctrl-F, the search bar at the bottom appears and holds the
selected text as the text to search for.
It also turns on the "search selection" checkbox. (Which is similar to D2009 behaviour), but if you then press F3
to search for the next occurence, you get dialog boxes "tried to search selected text, but no text was selected".
In previous versions the "search selection" was cleared when the selection in the editor was cleared according to
Darren Kosinski in the newsgroups (weaver.ide.editor).
A bit awkward if you want to use the keyboard to search for something by just selecting text, pressing Ctrl-F and
then F3 repeatedly like we used to be able to do.

[QC Description]
TDictionary search algorithm can deadloop under certain circumstances.
Particularly, when multiple powers of 2 (not including 2) number of keys are added to the dictionary, AND
TrimExcess() function is called, then search with any non-existent key lead to deadloop.
This is becuase the GetBucketIndex() function assumes if the search key does not exists, then eventually it will
hit an empty entry. This assumption fails when all entries are filled.

TComboBox KeyPress Filter Broken
Open attached project
Drop down the list

(Regression caused by Raid #269507)
[QC Description]
The following code in StdCtrls.pas (around
line 3947) was changed from this...
if HasSelectedText(StartPos, EndPos) then
SaveText := Copy(FFilter, 1, StartPos) + Key
To this (around line 4031) ...
// This call sets StartPos and EndPos
HasSelectedText(StartPos, EndPos);
if StartPos < Length(FFilter) then
SaveText := Copy(FFilter, 1, StartPos) +
Key + Copy(FFilter, EndPos+1, Length(FFilter))
I reformatted it slightly for word wrapping. Anyway, I'm not quite
sure what the intention of the new code is, but I have determined that
it breaks the original behavior of the combo box (this code is in the
KeyPress method). Here's how.
Suppose the combo box has 4 items:
Answer
Apple
Banana
Pie
And suppose that the Style is csDropDownList. In Delphi 2009, if you
type "ap" quickly, then you will be taken to "Apple". In the latest
Weaver, no matter how quickly you type "ap", you will be taken to
"Pie". The "a" takes you to "Answer", as desired, but the "p" takes
you to "Pie", which is not desired.

Package C:\Documents and Settings\All Users\Documents\RAD Studio\7.0\Bpl\DesignPackage.bpl can't be

It also compiled RuntimePackage.dpk (even though $IMPLICITBUILD OFF is specified for both packages)

Note that DesignPackage was built with RuntimePackage's flags and settings.
It should be a DesigntimeOnly package and the Description should be Designtime Test Package (Delphi 2010)
Steps with IDE:
1) Create a designtime package that references a runtime package containing a componet.
2) Ensure that the designtime package is not installed and no build artifacts are present.
3) Open both components in the project manager
4) Right click on the the designtime package and select Install from the menu
- Package compiles without error
- Install fails (package is not a designtime package)
5) Select the runtime package and select build
- Package builds OK
6) Select the designtime package *again* and select Install
- Package compiles and installs as expected

First part of the steps to get a test case and perform the search the first time to break the search (not the actual

control on the "Contents" tab - press CTRL+F - enter "end" in the search edit and press ENTER (see
"end" [end;] on line 13 is marked in black, "end" [end.] is NOT marked and there is no match count) Second part
of the steps (the actual problem) - close the project and reopen it - switch to the History editor tab - click into the
edit control on the "Contents" tab - press CTRL+F - enter "end" in the search edit and press ENTER expected: first "end" [end;] on line 13 is marked in black - there is no match count (per Darren is this as designed for

Before you start with the following steps make sure that QC 75439/RAID 270794 and QC 76730 is fixed! - start
the IDE - create a new Delphi console application - save it - remove the "{ TODO -oUser -cConsole Main :
Insert code here }" line - save it - switch to the History editor tab - switch to the "Content" History sub tab - click
into the edit control on the "Contents" tab - press CTRL+F - enter "end" in the search edit and press ENTER
(see "end" [end;] on line 13 is marked in black see also HistoryViewSearchResultCorrectRevision.png) - select
the Revision "~1~" in the Revision content virtual tree expected: the search result is resetted actual: the black
mark stays where it is (see HistoryViewSearchResultOtherRevision.png)
[QC Description]
After performing a search in the History view and switching to another revision the search result is not resetted.

Steps:
How to crash the IDE in a few steps
[QC Description]
Steps:
1) Create a new Delphi forms application and drop a TButton,
double klick to auto-create the OnClick handler.
2) In the event handler type some nonsense chars, ensure the
last char is not a semicolon.
3) Mark the nonsense string and move the curser to the right
within the _same line until some loop starts popping up
code insight windows infinitely (eats a lot of CPU time,
but IDE still survives).
4) While in that loop press the DEL key.
5) Move the curser to another line to stop the loop.

[QC Description]
The attached project demonstrates the error.
The setup:
Unit2 contains TBar, a non-Generic descendant from TObjectList<T>. (TObjectList<TObject> in particular)
type
TBar = class(TObjectList<TObject>);
Unit1 uses Unit2 and attempts to create an instance of TBar in Button2's OnClick handler.
var
Bar: TBar;
begin
{$INLINE AUTO}
Bar := TBar.Create;
Bar.Free;
end;
Attempting to compile the project will trigger the I12307 on the Bar := TBar.Create; line. Removing (or disabling)
the $INLINE AUTO directive will allow the file to compile successfully.
It appars to only affect the call site itself, because setting Inline to Auto in the project options also causes the
compiler error.
If the class declaration is in the same unit, the error is not thrown, as can be seen by TFoo and its corresponding
usage in the demo project.

[QC Description]
TComponent Interface functions like _AddRef or _Release are "redirected" to TInterfacedObject when a class
helper for TComponent or a TComponent descendant exists.
This is regression from D2007, but it happened already in D2009. This issue can lead to unexpected behavior,
because components are destroyed when the interfaces are released.

Original short description: Corrupted component interfaces
Original description:
I am running into a very strange bug with interfaces. Unfortunately it seems that i can only reproduce this on my
product which is about 200000 lines of codes making impossible to supply a code for reproducing. I'll try to
describe what happens in pseudo code bellow
Type
a = class(tcomponent)
b = class(a, IAnyInterface)
var
myobject: b;
implementation
in my code i a getinterface call on objects eg
myobject.getInterface(IAnyInterface, ivar)
The problem is that in function TObject.GetInterface(const IID: TGUID; out Obj): Boolean;
the statement
if Pointer(Obj) <> nil then IInterface(Obj)._AddRef;
Results to a call to TInterfacedObject._AddRef insteand of TComponent._AddRef. This behavior occurs only
with 2010 while 2007 and 2009 work as expected.
This causes the object to be freed and crash the app.
My application dosen't work with d2010 while worked as expected with d2007 and d2009

Database\DBExpress
Description:
Steps:
Impossible to use temp tables in mssql
-or-
[QC Description]
An application originally made with D2007 uses dbExpress to connect to MSSQL. For some functionality, it
creates temporary tables and fills these with data in consecutive statements on the same connection in the same
(implicit) transaction.
This worked great in D2007, but the same code fails in D2010. It looks like changes to the mssql dbexpress
driver in between versions has broken this functionality. (Don't know about D2009.)
Using explicit transactions does not help. Dmitry Arefiev suggested the driver might be using sp_execute
statements internally, which would explain the behaviour because that would create a new context for each
statement thus failing to recognize temp tables made in another context and therefore already dropped.
This is really basic functionality for our app and a showstopper for porting it to D2010 (unfortunately, because I
really like it even better than D2007).
Create a new application and drop a TSQLConnection and a TButton.
Connect the TSQLConnection to a MSSQL server by setting the Driver, Host and a Database.
To the button.OnClick handler attach this code:
SQLConnection1.ExecuteDirect('create table #TestTemp (something integer)');
SQLConnection1.ExecuteDirect('insert into #TestTemp (something) values (1)');
Expected: both statements run fine. If this program is made using D2007, it does.
If made with D2010, this application fails on the 2nd statement with the SQL error "Invalid object name
'#TestTemp' ".
QC Entry 77303
D2007 uses dbxmss30.dll. D2010 uses dbxmss.dll. If I make the D2007 version use dbxmss.dll, it fails too.
Unfortunately, it doesn't work the other way round.

GetTimeZoneInformation is very slow on Vista with programs compiled using RS2010
Also see attached projects: 1) Open Project1 in D2009 and compile and run it. 2) note execution time 3) Open
Project1 in D2010 and compile and run it. 4) note execution time When running on Vista (x32 or x64) you'll see
a huge difference between the two execution times. 1) Open Project2 and compile and run in D2010 2) note
execution time 3) Open Project2 and activate the $define USE_LOCALE_INVARIANT and compile using
D2010. 4) note execution time Again when running on Vista (x32 or x64) you'll see a huge difference between
the two execution times.
[QC Description]
On Vista GetTimeZoneInformation() is about a 1000 times slower when using D2010 compared to when using
D2009 (and earlier).
Also discussed here:
... and here:
program Project1;
program Project234;
{$APPTYPE CONSOLE}
{ $DEFINE USESYSUTILS} // define or not - test both
uses
Windows{$IFDEF USESYSUTILS}, SysUtils{$ENDIF};
var
I: Integer;
QPF, QPC1, QPC2: Int64;
tzi: TTimeZoneInformation;
begin
QueryPerformanceFrequency(QPF);
QueryPerformanceCounter(QPC1);
for I := 0 to 9999 do
GetTimeZoneInformation(tzi);
Writeln(CompilerVersion:10:2);
WriteLn('Execution time = ', (QPC2-QPC1)/QPF:10:6);
ReadLn;
end.
(On Vista Ultimate 64 SP2 on an Intel i7 920 2.67GHz)
D2009: Execution time = 0.005 s
D2010: Execution time = 5.289 s
It just worries me that a simple API suddenly takes about 0.5 millisecond to execute and am wondering if other
APIs are effected by this as well.
In the mean-time someone else found out that this is apperently caused by a SetThreadUILanguage call in
D2010 which sets some flag in Windows Vista which makes GetTimeZoneInformation call tzres.dll on every call
instead of only a few times in all the loops. On XP, only 0 is allowed, so there, LOCALE_INVARIANT is not used
anyway.
Note: this will not happen when you remove SysUtils from the above code.
To further prove this, following test was presented:
program Project2;
{$APPTYPE CONSOLE}
{ $DEFINE USE_LOCALE_INVARIANT} // define or not - test both
uses
Windows;
var
I: Integer;
QPF, QPC1, QPC2: Int64;
tzi: TTimeZoneInformation;
function SetThreadUILanguage(LangId: WORD): WORD; stdcall;
external 'kernel32.dll';
begin
{$IFDEF USE_LOCALE_INVARIANT}
SetThreadUILanguage(
LOCALE_INVARIANT); // In System.pas // getting res strings invokes its call.
{$ENDIF}
QueryPerformanceFrequency(QPF);
for I := 0 to 9999 do
GetTimeZoneInformation(tzi);
Writeln(CompilerVersion:10:2);
WriteLn('Execution time = ', (QPC2-QPC1)/QPF:10:6);
ReadLn;
end.
(Vista U64 SP2, D2010)
without SetThreadUILanguage: Execution time = 0.005452 seconds
with SetThreadUILanguage: Execution time = 5.045242 seconds
