Rand eines Windows nicht anzeigen

[Rastaman]

Delphi-Quellcode:

var
  dwExStyle, dwStyle: Cardinal;
begin
  dwExStyle :=  GetWindowLong(hWnd, GWL_EXSTYLE);
  SetWindowLong(hWnd, GWL_EXSTYLE, dwExStyle and not WS_EX_APPWINDOW);
  dwStyle :=  GetWindowLong(hWnd, GWL_STYLE);
  SetWindowLong(hWnd, GWL_STYLE, dwStyle and not WS_OVERLAPPEDWINDOW);
end;

Naja, eigentlich Quatsch dafür 2 Variablen zu nehmen, aber naja
