Tested with a persistent field and set the PK. It doesn't make a difference I still get: Project Project1.exe raised exception class EFDException with message '[FireDAC][Comp][DS]-200. Bookmark is not found for dataset [FDQuery1]'. Maybe UniDAC has a different implementation for bookmarks.

I've tested with fireDAC, the bookmark is never valid after reopen (however will find the record if you don't scroll the scrollbar). After every scroll I get: with a call stack: :763ec3a2 KERNELBASE.RaiseException + 0x62 FireDAC.Stan.Error.FDException(nil,???,26209084,???) FireDAC.Stan.Error.FDException($37E6CA0,???,200,???) FireDAC.Comp.DataSet.ErrorNoBmk FireDAC.Comp.DataSet.TFDDataSet.InternalGotoBookmark(???) FireDAC.Comp.DataSet.TFDDataSet.InternalGotoBookmark((144, 138, 137, 3, 81, 0, 0, 0, 5, 0, 0, 0)) Data.DB.TDataSet.GotoBookmark((144, 138, 137, 3, 81, 0, 0, 0, 5, 0, 0, 0)) Unit1.TForm1.Button1Click($37E6930) I know that this was the case with BDE, DBX and now FireDAC. For the reference my code is: procedure TForm1.Button1Click(Sender: TObject); var lbm: TBookmark; begin lbm:=fdquery1.Bookmark; fdquery1.Close; fdquery1.Open; if not FDQuery1.BookmarkValid(lbm) then ShowMessage('Not Valid!'); fdquery1.Bookmark:=lbm end;

Since Delphi 1. If you close and reopen the query the bookmark is invalid.

When you refresh the data the bookmark will no longer be valid. It's a pure luck if you don't see an error message. You shold remember the key of the active record before the refresh and call locate for it.

In that case you use the AddIndex merhod. For more information: https://docwiki.embarcadero.com/Libraries/Sydney/en/Datasnap.DBClient.TCustomClientDataSet.AddIndex here you can find a helper procedure https://edn.embarcadero.com/article/29056 to sort.

It's a bit different when the form is destroyed while application is running and when the application is closed / terminated. (The OS should/will clean up anything that is not freed by application.)

You have to set a flag inside the button3 onclick event handler. Later when needed you can check that flag and reset it.

Of course I don't have. I am a Delphi developer.

You can upload a zip file with a project and or a txt file with the description that will be not altered by the site.

Since the per-monitor dpi (v1) was introduced in Win 8.1 there should programs also work.

SynEdit is not part of the Delphi so it's hardly changed with Delphi upgrade.

Maybe you have an unpatched M1 chip. Working fine here in Chrome, Firefox and Edge.

Please send me a copy of D11.1 that works fine. I did my best to support highDPI unfortunately I see no way to do that with D11.1 maybe in D14 will work.

You can try $(BDSCOMMONDIR)\styles or $(BDSUSERDIR)\styles

Of course there is. It's true that the public roadmap is a bit old. However the company thinks that it's not important to inform us when we can expect a release or on what they're working now.

In VCL most probably you had turned off Range check and in FMX left it on.

In D11 you should check out also TCardPanel its made to replace that hack with TPageControl. Be aware it's not perfect yet will take a couple of versions to remove the bugs.

I've downloaded the source. There the data structure is not good for this task. I don't know when will have the time to write some example how would I desing it. This weekend is/was busy for me.

The text on the image that you've attached is not readable. As far as I can see you're using ODBC connection that is not configured on that PC. Be aware that windows have a 32 bit and 64 bit version of the ODBC Data Source Administrator and you have to create the data source in the one that matches your application. A 32 bit application cannot connect to 64 bit data source.

Turn on smart tab.

You should write which version of the Delphi you're using. For methods you can use Sync prototypes with the shortcut Shift+Ctrl+Alt+P. https://docwiki.embarcadero.com/RADStudio/Sydney/en/Code_Editor#:~:text=The Sync Prototypes feature is,name or the function modifiers.

First you should share your data structure then we can start to discuss how to implement those rules.

Now I get the same error while trying to debug Synedit 2. Just change something in source for SynEditDR.dproj to trigger compile as Break point stopped working and got an internal error.

Unfortunately that doesn't help for a VCL bpl. I have another common internal error: [dcc32 Fatal Error] core.dpk(358): F2084 Internal Error: AV11A8360D(11A60000)-R00FC101E-0 For this it was enough to add a period after the unit name: unit csv.; Try Compile the package (compilation failed as it should be), remove the period and when I tried to compile it I got this error. Of course I cannot reproduce this with a "hello world package".

A basic debugging or search in source code would be enough to find an answer. The application was unable to load the skia library - sk4d.dll.
