How do I prevent print screen

by

You can’t.

The best you can do is render to a hardware accelerated device on an overlay, similar to what video players used to do. Basically, you paint your entire window blue, and render your graphics onto the video card, and internally the video card will replace the blue with the graphics. The downside to this is you have to give up using winforms controls, and I don’t know of any way to do this with .NET easily. I think if you use DirectShow.NET, one of their samples is putting your own graphics into a stream.

Even after doing all of that, it’s still possible to get a screenshot. Just take a picture of the screen with a digital camera.
