I've been working on an ingame screenshot taker. While in fullscreen mode, a user is experience bad screenshots like this



He told me that it's not only my program, but it's a general problem on his system. Screenshot are taken correctly when he is playing in window-mode

I'm using BitBlt to get the screen. Any ideas where this problem could be... graphic card driver, windows virus, Vista problems, etc

Game Name : Quake III Arena

I can help identify the problem but don't necessarily have a solution.

I've seen this when a program (game) that is running displays a video image. The grey in the image is replaced with a video type file. I know from my own testing, with other software, that when the video plays, it is actually displayed on a different surface/layer called overlay that is produced by hardware acceleration. When you take a normal screen capture, you're taking it of the normal surface where the video isn't displayed. That's why it comes out grey because the overlay surface is invisible to the software capturing the screen.

Because the problem involves hardware acceleration, you can try turning hardware acceleration off under the settings for the video card or perhaps within the game.

Why not simply simulate a press of the print key? I just tested this MOH:AA, Counter-Strike, Max Payne and Hitman: Blood Money. No problems what so ever.

I have seen a similar problem with the print screen key.

yes he have this problem even when he press the print screen.

Because the problem involves hardware acceleration, you can try turning hardware acceleration off under the settings for the video card or perhaps within the game.

I have hardware acceleration on, and it works fine. I'll contact him when he is online, maybe if he disable it, it could work
