delphi Thread ITask.ExecuteWork not wait until Task finish in mobile devices?
Lajos Juhász replied to bravesofts's topic in Cross-platform
No. The reason to create a thread is to move to the next line without waiting for a block of code (inside the thread) to complete. That's the purpose for threads in every platform. -
delphi Thread ITask.ExecuteWork not wait until Task finish in mobile devices?
Lajos Juhász replied to bravesofts's topic in Cross-platform
On the other hand I believe you should learn a bit more about multi threading. -
delphi Thread ITask.ExecuteWork not wait until Task finish in mobile devices?
Lajos Juhász replied to bravesofts's topic in Cross-platform
On mobile devices you should never block the main thread (or risk that the OS will terminate your program). Without more details we cannot help you. Most probably you want to disable the UI elements that are not allowed while your background thread is executing. -

Is there a Sunday between 2 dates ?
Lajos Juhász replied to Henry Olive's topic in RTL and Delphi Object Pascal
you can ask AI to write this code. An anser from Bing function IsSundayBetween(StartDate, EndDate: TDateTime): Boolean; var Day: TDateTime; begin Result := False; // assume there is no Sunday between the dates Day := StartDate; // start from the start date while Day <= EndDate do // loop until the end date begin if DayOfWeek(Day) = 1 then // check if the day is Sunday begin Result := True; // set the result to true Break; // exit the loop end; Day := Day + 1; // increment the day by one end; end; -

'for i:= 0 to 4' does 6 loops when not in Debug mode
Lajos Juhász replied to Allan Olesen's topic in General Help
My guess is different memory layout in debug and release mode. That's why the code inserted to debug changed the behaviour of the bug. -
If you enable Runtime Themes you delegate the drawing for some components to Windows and the colors from the Active Windows Theme is used. In ancient versions of Delphi this was done through XPManifest. You can use VCL Styles to customize the drawing.

var x: real; begin SetExceptionMask(exAllArithmeticExceptions); x:=0/0 ; showmessage(FloatToStr(x)); Most probably some dll changes the exception mask.

One possible reasould could be that FindFirst would not return subfolders that doesn't match the pattern. If agree there are bugs for example (SR.Attr and faDirectory) = SR.Attr should be (SR.Attr and faDirectory) = faDirectory
-
Your code is working for me. A note that you're leaking memory findfirst will allocate some memory and that must be released with FindClose(SR). Also you should never write Form1.Listbox1.

it's already discontinued product )

I've never tested myself. A google search returned posts from 2001 that this is how MS Windows is designed: http://www.delphigroups.info/2/63/320384.html.
-
the original post doesn't said if it's a multiset or not.
-
The list would contain the control twice (like a multiset). If you don't want an object twice you can before add check indexof.
-
You could also use a generic list? That also has everything you wrote above.
-
I believe in Delphi you should use TDataObject.
-
The legal way is to file a bug report at https://quality.embarcadero.com/secure/Dashboard.jspa. The trial is valid for 30 days you can use that while it's valid and hope that embarcadero will release a patch for the CE edition or state clearly that it should not contain these files.

I would install the fulll fastmm4 version from https://github.com/pleriche/FastMM4 and enable LogMemoryLeakDetailToFile and FullDebugMode.
-
It should be possible with Delphi 11.3 https://github.com/Embarcadero/RADStudio11Demos/tree/main/Object Pascal/ToolsAPI/Editor Demos

Most probably one of other units define the TCompressionStream class. You can try to rearange your uses statement or prefix the classname with the unitname.
