Have you tried to debug or to have a call stack using a toll like madExcept?

To have effect you should call Application.ProcessMessages from the main thread while the work is done. This will open a can of worms but at least will work somehow. Otherwise you need to move the work in a thread.

With const, if the variable is small enough to pass into a register, it will not be passed always as reference. You need to use [ref] to be sure it is passed as reference. This is the reason to use [ref] for FreeAndNil.

In 12.2 function FindFirstFile; external kernelbase name 'FindFirstFileW'; ... function FindFirstFileW; external kernelbase name 'FindFirstFileW';

If you open the file with TPNGImage it will raise an exception if the content is not PNG. Not so hard to detect it is not a PNG content.

I think it should work with #if. Not tested. But you really want to install in that path? [Setup] #if FileExists('C:\mygame\TEST\install.exe') DefaultDirName=C:\mygame\TEST #else DefaultDirName=D:\mygame\TEST #endif

This is about Inno Setup? And you pascal code is not about Delphi but Inno Setup script? BTW here we are in: Home\Delphi Questions and Answers\General Help\

The panel should be enabled after the message is received and not in TfrmPanel.btnWriteASCII_ShrtClick() And disabling the panel should be done right before fTCPClient.IOHandler.WaitFor() when you know that WaitFor() is executed.

The OP is disabling only the panel and that will not disable the button. Angus solution will solve the problem because the function will disable the button that will not pump the windows messages.

Are you storing float in string fields? I create fields as REAL in SQLite and I can change the decimal separator without issues. I see period or comma and all is working. I can update a REAL column using period in sqlite3 tool, because the tool uses only period, and I can see values with comma in my app.

You don't trick SQLite. FireDAC is using this information. You can look in FireDAC.Phys.SQLite.pas unit at FDSQLiteTypeName2ADDataType() to see how this is done.

It would be better to debug. I do not see this behavior. Delphi 12.2, Windows 11 Version 10.0.26100 Build 26100

Delphi 12.2 supports Windows 7 (SP1+) If we are speaking about OS versions, language enhancements doesn't matter but API function calls. https://docwiki.embarcadero.com/RADStudio/Athens/en/Supported_Target_Platforms

You can open a feature request and describe the issue to Embarcadero asking them to obfuscate a little the string for example with a simple and fast xor.

Have you tried FideDAC Mapping? From the link provided by Dmitry I see two things you can try (specify type name in column alias and mapping):
