title: How to prevent screenshot from program
body: <p>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?</p>
  
  <p>I want this for C# WinForms.</p>
  
  <p>P.S. I know it is a bit stupid, user can take a real photo of the screen :P but just my curiosity!</p>
