    Real time access to display image

    Is there a method for accessing the display image that can be run at a high framerate, i.e. 30 fps or higher? I want to write a small application that records a video of the game I am playing. I can handle raw DIB etc.
    Until you can build a working general purpose reprogrammable computer out of basic components from radio shack, you are not fit to call yourself a programmer in my presence. This is cwhizard, signing off.

    Sorry, perhaps I'm not reading very well, but do you mean "read back what's on the screen" or "display something on the screen"?

    The code in that link looks about right. You probably won't get overlays/video/cursor in the bitmap. Unfortunately, reading back from the framebuffer isn't exactly the fastest thing you can do, but it should work. Of course, you wan't to set a timer for 33ms to capture 30 fps. Should be doable, I think.
