OpenGL snapshot

Hi there!
I am trying to take a snapshot from another process, to be exact Counter-Strike.
Under Windown XP I could take simple snapshots using GDI functions, but it doesn’t work under Windows Vista/7 because of the new look of the Windows.
I have tried getting the HDC and HRC of the other process, but it seems I cant get the HRC. I got the HDC using this code:

hwnd = FindWindowA(0, “Counter-Strike”);

if (!hwnd)
printf("Open Counter-Strike to begin
while (1)
hwnd = FindWindowA(0, “Counter-Strike”);
if (hwnd) break;

DWORD proc_id;
GetWindowThreadProcessId(hwnd, &proc_id);
hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, proc_id);

if (!hProcess)
printf("Cant Open Process
return 2;
*hDC = GetDC( hWnd );

now because I dont have an HRC when I am trying to use glReadPixels, it doesnt work.
I saw this feature in a program named Fraps, and started looking for a solution some time ago, so now I thought you guys may be able to figure out how it is possible to be done.


Search for TAKSI project on sourceforge… same as fraps, but opensource.

Thank you!
I’ll check it right now.
