title: C++ Draw a small dot in the center of a screen
body: <p>I want to draw a small dot at the center of the screen so that it must remain after running of any application. A dot should stay even after I launch an application in full screen mode. Like a dead pixel.</p>
  
  <p>I have already installed Visual C++ on my computer with Windows 7. I have some experience with C++, but I never worked with graphics under Windows OS.</p>
  
  <p>How can I draw a dot on a screen?</p>
