title: Executing "Show Desktop" from C++
body: <p>I am designing a system where the user makes a gesture, then my program captures it (using a web cam) and my program looks in a rule system (based on XML) which are the actions that it has to do.</p>
  
  <p>Ok, once I have explained the background, I'd like to know how I could make my program "execute" the Show Desktop button. I'd like to provide the user the possibility to do a gesture and show the desktop. Is it possible? I have been looking the program (.exe) that executes the Show Desktop button and I am afraid that does not exist.</p>
