0005060: Wrong Display and Return of Float Values by TJvValidateEdit

TJvValidateEdit converts Float to String by using the normal Delphi function StrToFloat. This function uses ThousandSeparator and DecimalSeparator loaded from SysUtils by calling:
GetLocalChar(GetThreadLocale,....)

To convert from String to Float TJvValidateEdit calls JvSafeStrToFloat from the JVCL unit JvJCLUtils. This function loads own Chars for ThousandSeparator and DecimalSeparator by calling:
GetLocalChar(LOCALE_SYSTEM_DEFAULT,....)

Not for all but for some of our computers the ThousandSeparator and DecimalSeparator used for Float to String conversion are different from these used for String to Float conversion.

This causes a lot of trouble and makes the component unusable.

0005286: Copy in and from Id3v2x.

I have tried several times to copy info from an mp3 (id3 tag v1.x to id3 tag v2.x) and the artist doesn't copy. The other way around works perfectly.

0005285: TJvDBGrid - Columns can't be moved

Add a TJvDBGrid to any form. It is not possible to move columns right clicking in their titles. Right click does not select the title. The problem was introduced as a proposed fix for problem described in issue 4421. I downloaded all revisions of JvDBGrid.pas and compiled a sample application with each of them in order to find when the problem was introduced. The problem was introduced in revision 11940.

I am pretty sure that who made the change assumed that the proposed change in issue 4421 was correct and not bothered to test it.

0005204: TjvDBGrid and property FixedCols >0

1. Wrong rendering a font of fixed columns i.e. for a fixed columg using a font of the next column.

2. Rendering fixed columns with artefacts in D2010, if a property DrawingStyle <> gdsClassic (pic. err_D2010_grid.JPG).

3. If FixedCols >0 and a selected column is outside a visible grid, during changing width of any column there is a scrolling to the selected column. It's not conveneint when I need to set several columns. When FixedCols = 0 there is not the problem.

0005284: mask in jvdbGrid

I used to see altomatic masked string in DBGrid just setting the EditMask property of TStringField (without using the OnGetText event) but in jvDbGrid it does not. In jvdbGrid that just happens to DisplayFormat property of TFloatField, TExtendField

0005283: Multiple Dockservers or Custompanels support

I'm having a pagelist with a variaty of forms docked at one page using the CustomPanel feature.
Now if I change to a new page I'd like to be able to dock a new set of forms for that page.

I can think of two ways to achieve this.
One: By supporting multiple CustomPanel's for one JvDockServer.
Two: Enabling multiple JvDockServer's on a form and assigning an indiviual CustomPanel to each one.

Looking at the code I think the first solution would be difficult regarding the maintenance of splitters and such.
The second solution would be easier I think, but possibly creates an ambiguity for the code's Find functions such as FindDockServer() and so on.
I'm trying to create the patch myself but any suggestions or patches would be very welcome.

0005015: first line of stack list details generated only, debug report is not complete

There is "List index out of bounds (1)" error in TJclStackInfoList.AddToStrings method, line 4773 in JCLDebug.pas
Strings.Add(GetLocationInfoStr(Items[I].CallerAddr, IncludeModuleName, IncludeAddressOffset, IncludeStartProcLineOffset, IncludeVAddress));

0005281: EIntOverflow in NextStackFrame line 4825

I get EIntOverflow in NextStackFrame line 4825 when a database error occured as you can see bellow where i have copied ID call stack

0005282: ExceptDlg does not work if app is compiled with package vcl and bounds-checking on (with solution)

During the display of the exception Dialog stack trace, you'll get various errors depending on the project you use. Sometimes "Out of Memory" exception is thrown, often a "ListIndex out of bounds (2)"

0005258: TJvBalloonHint NOT painting on Windows 7

BalloonHint painting entirely transparent. Visible only edging.
I compile in Delphi 2007 project BalloonPrj.dproj in folder examples\JvBalloonHint\.
On Windows XP and Vist Hint painting correctly. On Windows 7 - transparent. See example in the attached picture.

0002265: Feature request

I'd like to see "IsAdministrator" function carved up such that it calls
something like "IsAliasOf( IsSomeAlias : DWORD )"

That is, we'd then be able to have:

IsPowerUser := IsAliasOf( DOMAIN_ALIAS_RID_POWER_USERS );
IsAdministrator := IsAliasOf( DOMAIN_ALIAS_RID_ADMINS);
IsBackupOperator:= IsAliasOf( DOMAIN_ALIAS_RID_BACKUP_OPS);

etc.

0005280: Error in JvCsvDataSet Filter

JvCsvDataSet Filter returns a Result, even when non-matching Criteria is given.
In the program, when "Box" or "Carton" is selected, result is fine (correctly filtered); but when "Garments" is selected, it returns the first record from database (csv file) although there are NO record(s) of Garments in the database.

0005279: Stack trace from JclLastExceptStackListToStrings truncated for Acess Violation in thread

In the main VCL thread and most of the time in other threads JclDebug.JclLastExceptStackListToStrings works brilliantly However for an access violation in a thread it reliably gives me only one entry in the trace - the first one. The line number and description are accurate, but it's not very useful as it'll often be for a line somewhere in the VCL.
If I put a "raise Exception.create('error message');" line before the AV-causing line I get a full stack trace.
The sample code below should work added to a bare Delphi application.

0005278: JvInterpreter and #XX character codes..

JvInterpreter does not handles 0000010, #XX character constants with string constants.

This does not work in JvInterpreter, but works in standard Delphi compiler since 1.0 version:
var
s: String;
begin
s := '';
s := s + 0000013#10'Hello'0000013#10;
end;

0005276: Console client doesnt sync all files

Hi All,

I'm attempting to automate our build process, part of the is automating the source code synchronising. I'm using the Jedi commandline interface. My issue is that when I sync from the command line, the output says it's getting every file in the project, but when I inspect the destination directory not all files are there.

I've set the destination directorys security to allow 'everyone' to read, write etc.

I've tried the same command from diferent machines with the same result.

I saw some other posts related to encryption with the console client saying that encryption is not supported and will be soon. These posts are from years and years ago. Could this be the issue? Is encryption now supported?

please help me figure out why the missing files aren't there.

0005277: Donation Components

Hello, may I suggest a small set of components, which seem to me useful.

0005253: TJvTimer (possibly other timers also) does not free thread

TJvTimer (possibly other timers also) does not free thread when changing Enabled property in Timer event. This lead to out of resources exception if timer are created in big quantities.

0005233: TJvDBGrid wordwrap

It will be good to add special event for DbGrid called like "OnColumnWordwrap" returning bollean if drawed column must be wordwrapped.
If we allow row resizing, then really I see only OnDrawCell possibility for that or modifying source unit and then including it into project.

0005237: [TJvDBUltimGrid] On master-details view the 'sort title' action looses the details

If you have two TJvDBUltimGrid, one for the master table and one for the details table, the details grid shows no rows if you sort with respect to a key that is not the master-details relational key, by pressing the title buttons.

0005275: Installer fails to set up resources directory for C++ compilation

Every time I install JVCL, I have to go under Tools, Options, Environment Options, C++ Options, Paths and Directories, and add JVCL's resources subdirectory (e.g., C:\trunk\Libs\jvcl-3.39\resources) to the Library Path option.

0005274: TJvTrayIcon Access Violation if length of hint is more than 255 symbols

When I try to show long-length hint via TJvTrayIcon component, then I catch an Access violation message. Also, part of string from text goes to caption. Screenshot is attached.

0005250: TJvDbLookupCombo doesn't properly redraw at run-time with XP Theme enabled

TJvDbLookupCombo placed on a form in TJvPageConrol

object dblcbElementA: TJvDBLookupCombo
Left = 8
Top = 32
Width = 145
Height = 21
DropDownCount = 10
Font.Charset = RUSSIAN_CHARSET
Font.Color = clBlack
Font.Height = -11
Font.Name = 'Tahoma'
Font.Style = []
LookupField = 'Id'
LookupDisplay = 'Name'
LookupSource = dmPathMan.dsElementA
ParentFont = False
TabOrder = 0
OnChange = dblcbElementAChange
end

At run-time the selection button with "open" arrow doesn't properly redraw it's background.

dblcbElementA.ControlStyle := dblcbElementA.ControlStyle + [csOpaque] doesn't help. Copmponent gets background from previous Page on PageControl.
Removing .manifest file helps to restore the view but without XP theming.

0005273: JclLANMan LookupGroupName does not allocate buffers correctly, which causes access violation in NTDLL.DLL

The LookupGroupName function in JclLANMan is not converted correctly to support Delphi 2010. The buffers must be allocated or the second call to LookupAccountSID will fail, causing an access violation in NTDLL.DLL
This function will work if compiled with earlier version of Delphi.

0005271: Bug in TJvDockServer, TJvDockClient

=== BUG in TJvDockServer, TJvDockClient ===

When we trying to dock OTHER dockable components (e.g. ToolBar) on a DockPanel (property of a DockServer), we have ACCESS VIOLATION error message (everytime). Other problem: standard (and Jv_ also) ToolBar do not have visible caption when its docked on a DockPanel.

Thanks,
Vitaly
