MainWindow anhand der ProcessID ermitteln ?

[shmia]

Kopiert aus der JCL:

Delphi-Quellcode:

function IsMainAppWindow(Wnd: THandle): Boolean;
var
  ParentWnd: THandle;
  ExStyle: DWORD;
begin
  if IsWindowVisible(Wnd) then
  begin
    ParentWnd := GetWindowLong(Wnd, GWL_HWNDPARENT);
    ExStyle := GetWindowLong(Wnd, GWL_EXSTYLE);
    Result := ((ParentWnd = 0) or (ParentWnd = GetDesktopWindow)) and
      ((ExStyle and WS_EX_TOOLWINDOW = 0) or (ExStyle and WS_EX_APPWINDOW <> 0));
  end
  else
    Result := False;
end;
