    You should define your view in Tools - Options. You can find it if you navigate to User Interface - Form Designer - Device Manager or just write Device manager into the search edit box at the top. https://docwiki.embarcadero.com/RADStudio/Alexandria/en/Adding_a_Device_Preset

    What is your experience Debugging Front and Back with MVC Delphi?

    Lajos Juhász replied to Juan C.Cilleruelo's topic in Delphi Third-Party

    My only experience with this kind of debugging is that it's going to result a request time out.

    Display Value at runtime

    Lajos Juhász replied to limelect's topic in Databases

    I cannot fully understand the question either. My bet is that the TDBgrid for blob fields instead of the value displays (Memo). In order to correct that a solution is to use the OnGetText event of the TMemoField/TWideMemoField:

    For me it made unstable. There was no chance to do compile all for a large project group. The solution was to add scopes to unit names and improve code structure and reduce circular references.
  6. Lajos Juhász
    For me MMX Code Explorer works perfectly to reduce circular references (Unit dependency Analyzer). For compiler stability possible it's more important to write the entire unit name eg. Winapi.Windows instead of Windows and having a large list of unit scopes names in the options.

    FireDAC Create table with TFDTable class at SQL Postgres 14

    Lajos Juhász replied to shalapai's topic in Databases

    I cannot help here. If you're going to feel better I have similar issues with auto generated SQLs on Informix. My solution is to generate SQL in my code and don't rely on auto generated statements.

    Delphi 10.2 add Windows Codesign

    Lajos Juhász replied to RTollison's topic in General Help

    You have to download the Windows SDK and use the signtool. (https://learn.microsoft.com/en-us/windows/win32/seccrypto/using-signtool-to-sign-a-file).

    TCalendarView returning a bad Date

    Lajos Juhász replied to Andrew Spencer's topic in VCL

    I can confirm using both OnClick and OnChange events that I can receive: 45113 -700000 45113 -700000 45113 -700000 45113 -700000 45113 -700000 45113 -700000 45113 -700000 45113 -700000 45113 -700000 45113 -700000 45113 -700000

    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.
  13. Lajos Juhász
    On the other hand I believe you should learn a bit more about multi threading.
  14. Lajos Juhász
    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.

    Setting Font Color on certain controls

    Lajos Juhász replied to Andrew Spencer's topic in VCL

    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.

    0/0 => EInvalidOp or NAN ?

    Lajos Juhász replied to FabDev's topic in RTL and Delphi Object Pascal

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

    File Search

    Lajos Juhász replied to robertjohns's topic in VCL

    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

    File Search

    Lajos Juhász replied to robertjohns's topic in VCL

    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.
