    Capture Screen OpenGL & Vista

    Language: .NET C#

    - Win XP + Game in openGL = OK (valid screen)
    - Win XP + D3D/Software = OK (valid screen)
    - Vista/Win7 + Game in openGL = NOT OK (black screen, i see my text i put on the screen though)
    - Vista/win7 + D3D/software = OK (valid screen)

    Does someone know how i can take a valid screen when running in openGL mode?

    You mean taking a screen capture?
    On my Vista + OpenGL application you can just press PRINTSCREEN key and Vista puts the image on the clip board. One Vista feature worth having!

    Win XP has no such facility which is why most apps write their own code to read the GL Window/context directly.

    every x minutes you could press printscreen, or alt+printscreen to capture the active window.

    if you want to get REALLY fancy with it i think glReadPixels is your screen grab buddy.
