how to disable capture screen

[SuperNeo]

Hello, everybody. Who can tell me how to disable capture screen?

I need to write a program, when I run this program, any screen-capture software will not work.

Thank you for your help!

What kind of program could you possibly write that would need to disable screen capture? You may be able to hook the Print Screen key, but you'll never be able to stop all the possible programs out there that make the API calls to capture a screen through its own built in functions. Any facilitiy that is worried about sensitive data has measures (physical) in place that are far more secure than you could ever write in a C# program. And if you're writing something for the general public then you can expect people not to be interested in it if your trying to hack other programs on their computer that have screen capturing to them lose there ability to function (those are called spyware and virus').

If it is in your application and someone presses the Print Screen button, you could try to immediately flush the Clipboard contents.

 

Or, better yet, edit the Clipboard picture so that your name is plastered all over it.

 

BTW: I've never personally worked with the Clipboard contents, but I've read a lot of little snippets of code about working with it. It'd take me a bit to figure out exactly how to flush or edit that pic.

Even if you disable the Prnt-Scn button, many people have third-party software that can do the same thing. I would take this requirement off my list.
