title: How to draw to screen in c++?
body: <p>How would I draw something on the screen ? not the console window but the entire screen, preferably with the console minimised.</p>
  
  <p>Also, would it show up on a printscreen ?
  What I want to do is create something like a layer on top of the screen that only me and my aplication are aware of yet still be able to use aplications as usual.</p>
  
  <p>Here's an example:
  Let's say I want 2 yellow squares 5 by 5 pixels in size appearing in the center of the screen on top of all the other applications, unclickable and invisible to a printscreen.</p>
  
  <p>[Edit]</p>
  
  <p>I forgot to mention that I'm using Visual Studio 2010 on Windows XP.</p>
