Is there a way to protect a program from any form of screenshoting by users? For example I do not want my program to be in a screenshot when user presses Print Screen key on the keyboard. Is it possible to make somehow a key preview in the program that minimizes the program on pressing Print Screen keyt by user?
I want this for C# WinForms.
P.S. I know it is a bit stupid, user can take a real photo of the screen 😛 but just my curiosity!
Only thing that I could think of right now would be using a video overlay to draw the application’s contents (i.e. similar to classiv video players). That way usual screenshot programs will just get a blank/almost black image. But it’s still no 100 % secure way. Everything that passes through software can be manipulated/grabbed in some way.
