Firebird 5.0 with dbExpress (Delphi 12): unknown ISC error 0
Achim Kalwa posted a topic in Databases
Hello *, our application still uses Firebird 3.0.x with dbExpress for data access. We would like to use Firebird 5.0 in the near future. Some first tests throws an exception "unknown ISC error 0" when executing this simple SQL query: select * from MON$DATABASE Looks like dbExpress can't handle the new "TIMESTAMP WITH TIMEZONE" data type. Is there any switch or parameter to make dbExpress work with Firebird 5? Or do we need to change all the code to use FireDAC? TIA Achim -

Weird error on latest SVN source release build with D12 (fix versio)
Achim Kalwa replied to Tommi Prami's topic in GExperts
It is a bug in Delphi 12 (and also Patch 1): https://quality.embarcadero.com/browse/RSP-42675, reported 3 month ago. You need to unload the project and load it again when switching from debug to release or vice versa. -
This one is also related to integer division (currency), but I am not sure if its the same cause: https://quality.embarcadero.com/browse/RSP-42753 D12 is currently not usable for me.

Very strange; none of the source files tries to include a resource file My.RC. Perhaps somewhere in the include path? Do you compile on the command line or from the Delphi IDE? Regarding the missing GExperts_manifest.res: Please try to remove the line {$R 'GExperts_manifest.res' '..\..\Source\GExperts_manifest.rc'} from the end of then GExpertsRS120.dpr file and compile again. I've no idea why the GExperts_manifest.rc is NOT compiled if the $R directive is below the uses list. If I move the $R to the top of the DPR file; just below the {$E dll}, the rc file is compiled into a res file; if compiled from the IDE. I'm going to remove that manifest thing from the D120 source for now until I find a reliable solution.

I can not confirm with TNumberbox (VCL) ; both Delphi 11.3 and 12.0: Ctrl+A then Delete clear the edit field; and I can type the new value. Which are your values for MinValue and MaxValue? Any non-default property settings?

StringGrid: how to get the column number via right-click
Achim Kalwa replied to JohnLM's topic in VCL
Hi, Use the Grid's OnMouseUp event: procedure TForm4.gridMouseUp(Sender: TObject; Button: TMouseButton; Shift: TShiftState; X, Y: Integer); var ACol, ARow: Integer; begin if Button = TMouseButton.mbRight then begin grid.MouseToCell(X, Y, ACol, ARow); ShowMessage('Col: ' + ACol.ToString); end; end; HTH -
It is not your code, it is the IDE's form designer which ignores the color. Please try Tools->Options->User Interface->Form Designer and uncheck the "Enable VCL Styles" option.

Hello alogrep, let me answer your 2nd question first: This dialog is somewhat misleading IMHO; read carefully. It tells you that the previous version will be uninstalled if you click "uninstall". The Yes/No-selection in the dialog is about removing stored data from the registry. "No" means "keep all settings", which includes library/search path, toolbar configuration, installed packages and much more. Which leads to your 1st question: No. If you decide to keep the registry settings by choosing "no" (see above), all your own and/or 3rd-party components will be availabel in V11.3. This because V11.2 and V11.3 are binary compatible. HTH

Delphi beta testing a "premium" privilege?
Achim Kalwa replied to Brandon Staggs's topic in Tips / Blogs / Tutorials / Videos
Don't panic; Uwe is right. I have reliable information that users with normal Update Subscription will also be invited to the beta test, but only a few days/weeks later. Merry Christmas to you all. -
If you want to see the TextHint even if the TEdit control has the focus, you need to send EM_SETCUEABANNER to the control: https://learn.microsoft.com/en-us/windows/win32/controls/em-setcuebanner like this: uses ... WinApi.CommCtrl, ... procedure TForm1.FormShow(Sender: TObject); begin SendTextMessage(Edit1.Handle, EM_SETCUEBANNER, WParam(True), 'please type here'); end; WParam(True): if the cue banner (text hint) should show even when the edit control has focus. Be aware that VCL controls sometimes gets recreated, resulting in a new handle value and losing previous settings. A better way would be to inherit from TEdit and overwrite the protected DoSetTextHint() method like this: Interface uses ... WinApi.CommCtrl, Vcl.Themes, ...; type TMyEdit = class(TEdit) protected procedure DoSetTextHint(const Value: string); override; end; TEdit = class(TMyEdit); ... Implementation procedure TMyEdit.DoSetTextHint(const Value: string); begin if CheckWin32Version(6, 1) // Windows 7 and up and StyleServices(Self).Enabled and HandleAllocated then SendTextMessage(Handle, EM_SETCUEBANNER, WPARAM(True), Value) else inherited; end; HTH

Reinstalling Delphi: Use Installer for 11.1 or 11.1.5?
Achim Kalwa posted a topic in Delphi IDE and APIs
Hello *, It is a nightmare to install Delphi patches because I have to use two different Windows user accounts; one for installing software, the other one for normal work. And because the patches are remembered in the user's registry during installation, they always end up in the wrong user registry path. Now I'm going to install Delphi 11.1 on a new machine. Is there an installer which already containes the patches and hotfixes since the 11.1 release? On my.embarcadero.com I can download "RAD Studio, Delphi, C++ Builder 11.1 Web Install"; filename: RADStudio_11_1_esd_10_8973.exe (2022-03-15) "RAD Studio 11.1 patch 1" (2022-04-27) "Windows 11 Win32 Debugging Patch for RAD Studio 11.1" (2022-05-27) But there is also a "RAD Studio, C++Builder 11.1.5 Web Install"; filename RADStudio_11_1_5_esd_10253.exe (2022-07-14), but without "Delphi" in the title. Maybe this sounds like a stupid question because "Delphi" is not mentioned: Can I use this for installing Delphi 11.1 and all patches until July 2022? Usually the installer knows what to download by my license key. TIA Achim -

11.1 IDE woes with multiple monitors and different dpi.
Achim Kalwa replied to Damon's topic in Delphi IDE and APIs
Yes, even Delphi 11.1 has a lot of issues with changing display dpi. The only way to "solve" most of this problems is to run the IDE as "DPI unware" (there is an entry in the Windows start menu). But all fonts/icons/designer will be blurry on your 150 dpi display; just as Delphi 10.4 was. -
Gexpert is crashing after uninstalling and reinstalling Delphi (keeping Reg settings)
Achim Kalwa replied to Stéphane Wierzbicki's topic in GExperts
I can reproduct it using the "GetIt package installer": When installing a package which requires an IDE restart (i.e. "Bookmarks" or "Navigator"), or when installing the latest patches, I always get the exception. See attached video. GExperts Crash.mp4 -
Gexpert is crashing after uninstalling and reinstalling Delphi (keeping Reg settings)
Achim Kalwa replied to Stéphane Wierzbicki's topic in GExperts
When the installer is running ("RAD Studio Platform Selection"), there is no "installer" process, just bds.exe. So it *is* the IDE but in a special download mode. When all is installed and "Start working" is clicked, the bds.exe is terminated and a new instance of bds.exe is started. That is the time when the error message appears. I already detected that the old instance is killed using Windows API "ExitProcess"; and my guess is that this will not unload the GExperts dll nicely. -
Delphi 11.1 is available
Achim Kalwa replied to Uwe Raabe's topic in Tips / Blogs / Tutorials / Videos
Thanks. Clearing the "light" theme did help. But I can't use a custom theme. I can load a custom image, but the IDE always stays on "light" theme. -

I just want to get rid of that colorful gradient image; it hurts my eyes. -

Any hints on how to customize the background image on Welcome page? Changing the theme in Tools -> Options -> Welcome Page, or loading a custom image, has no effect 😞 -
Have a look at this plugin for Outlook which enables drag & drop of any item to applications: https://github.com/tonyfederer/OutlookFileDrag Maybe you find out how it works and port the code to Delphi. If you succeed, please make your solution open source, because I would like to implement it to our application, too 😉 Currently we rely on this plugin.

After reading your post, my first idea was to extend the GX_ExplicitFilterExpert to patch the TCustomForm.DefineProperties() method the same way as for TControl, then adding a WriteProperty('OldCreateOrder', True). But when TCustomFormFixOldCreateOrder calls "inherited DefineProperties", the code recursively calls itself, resulting in a stack overflow. So, I don't have any good idea to solve this problem 😞

Yes, there is "DDevExtension" by Andreas Hausladen. That IDE plugin has an option to disable the alpha-sort class completion (and much more valuable stuff): For Delphi 2009...10.4.2 you can download this plugin form Andreas' blog: https://www.idefixpack.de/ For Delphi 11 there is a fork on Github: https://github.com/DelphiPraxis/DDevExtensions/releases

In line #3 the list of variables must me terminated by a semicolon, not by a comma. Beside that your code works as expected (Delphi 11.0). And because you did not tell in which line the error occours I can only wild guess that there is some other "SplitString" function in reach with uses different parameters. Where do you land when doing a Ctrl+Click on "SplitString"?

Menu captions with images are hard to read under Windows 11
Achim Kalwa replied to Tom Mueller's topic in VCL
Embarcadero has fixed the menu font color problem in V11 update 2. I really would like to know why Microsoft discarded the well-looking menu colors from Windows 10 and now uses the Windows-2000-colors for menus. And the selection bar height is 2 pixel too small on Windows 11, which makes font decenders difficult to see. At least Microsoft has "fixed" the bar height on recent Windows 11 builds. -
When `Scaled` is set, form inheritance will cause duplicated scaling? Any one can confirm?

Any special alignments of panels and buttons (Bottom, Right)? Can you provide a sample project?
