title: Use HWND to toggle application fullscreen
body: <p>So I am trying to move another application to a second screen and then I want to set it full screen in C++.</p>
  
  <p>I have the HWND handle from the application from a list of processes and then I can set the position from the window where I want with MoveWindow. This works perfectly. </p>
  
  <p>Is there a similar way to set the application to full screen? I can only seem to find info about setting your own application to full screen. But in this case I want to be able to move any application I want and set it to full screen. (As far as this is possible, but for the purpose I need it it should be)</p>
  
  <p>If I press Alt+Enter on the window after moving it, it does exactly what I want. So I hope I can do that from code?</p>
  
  <p>EDIT: BTW I tried ShowWindow(windowToMove, SHOW_FULLSCREEN);
  But it seems to maximize it but it is not similar to ALT+ENTER.</p>
  
  <p>Thanks for any help in advance!</p>
