title: How to lock the screen in Windows?
body: <p><br /><br />
  Usually I develop in Java but now I need to write an app that will block the whole computer's screen every X minutes for Y minutes. It needs to make a break (I want to have a similar app in Windows like in Linux).<br/><br/>
  So I suggest I need to use C++ and User32.dll to achieve it? Am i right? (I don't want to develop an application in C#). Could anybody give me an idea which methods to use to lock the screen, I'm a newby in WinAPI developing.

  Thank you!</p>
