Thread: making a absolute overlapped window, even overlap games

Code:

	hwnd = CreateWindowEx(
		 WS_EX_TOPMOST ,
		"myWindowClass",
		"The title of my window",
		WS_OVERLAPPEDWINDOW,
		CW_USEDEFAULT, CW_USEDEFAULT, 240, 120,
		NULL , NULL, hInstance, NULL);
	
	
	
	
	
	SetWindowPos(hwnd,HWND_TOPMOST,0,0,0,0,SWP_NOOWNERZORDER);

how do i make an absolute overlapping window that overlaps everything, even games like "call of duty" that insist on overlapping all other windows? i need to create a overlapped desktop timer for the cybercafe where games can see the time remaining before they have to pay up. the above code overlaps most window but not the games ones
