Luckies "myIsDebuggerPresent" liefert immer true

[Teekeks]

Delphi-Quellcode:

function MyIsDebuggerPresent: Boolean; assembler;
var
  BeingDebugged: Boolean;
begin
  asm
//   push eax;
   push ebx;
   mov eax, fs:[$18];
   mov ebx, [eax+$30];
   mov eax, [ebx+2];
   mov [BeingDebugged], al;
   pop ebx;
//   pop eax; // Wichtig! POP immer in umgekehrter Reihenfolge von PUSH
  end;
end;

procedure TForm1.FormCreate(Sender: TObject);
var
  ...
begin
  ...

  if (myIsDebuggerPresent) then
    ShowMessage('Ja');

  ...
end;
