The closest equivilent to your XCode approach is to use an “interposer” class in Delphi. Basically, you do not change the code that the IDE creates for the standard TToolBar usage. You instead declare a new class that derives from the standard TToolBar component but is also named TToolBar and you make it visible to … Read more
The difference has to do with where you’re allowed to refer to the things that AConsts has in its interface section. In the first AUnit, you could use Const4 to declare a fixed-size array in that interface section. You couldn’t do that in the second AUnit because Const4 isn’t in scope. It can have an … Read more
Writing a thread safe code in Delphi involves the basic care you would have in any other language, which means to deal with race conditions. A race condition happens when different threads access the same data. A good way to deal with that is to declare an instance of TCriticalSection and wrap the dangerous code … Read more
According to this you should be able to get one with the InitializeSecurityContext windows API call.
You can indeed use Assert for this. Write a procedure that matches the signature dictated by the TAssertErrorProc type, and then do whatever you want there. To preserve the expected behavior, you should probably call the original handler after you’re finished. procedure MichaelAssertProc(const Message, Filename: string; LineNumber: Integer; ErrorAddr: Pointer); begin LogMessage(…); SysUtils.AssertErrorHandler(Message, Filename, LineNumber, … Read more
Having the application close when the last form is closed is a Windows thing. An Android app will keep running. To close the app on Android, call SharedActivity.finish from the FMX.Helpers.Android unit.
If you are NOT using Android 6 Marshmallow, OpenSSL should be working fine on Android. When you get the “could not load” error, you can call Indy’s WhichFailedToLoad() function in the IdSSLOpenSSLHeaders unit to find out why OpenSSL could not be loaded. If your device does not have OpenSSL pre-installed, you can deploy the OpenSSL … Read more
GetText should be able to do, search for “extract” at http://dxgettext.po.dk/documentation/how-to If all you need is to translate GUI and maybe resourcestring in sources, and the inline string constants in Pascal sources are not needed for translation, then you can try Delphi built-in method. However forums say that ITE is buggy. But at least that … Read more
The following gets the job done: hWnd = CreateWindow(…); SetWindowLong(hWnd, GWL_STYLE, WS_POPUP | WS_MINIMIZEBOX); SetWindowLong(hWnd, GWL_EXSTYLE, 0); ShowWindow(hWnd, …); You were probably missing WS_MINIMIZEBOX.
Assuming that you have no need for floating point exceptions to be unmasked in your application code, far and away the simplest thing to do is to mask exceptions at some point in your initialization code. The best way to do this is as so: SetExceptionMask(exAllArithmeticExceptions); This will set the 8087 control word on 32 … Read more
