title: How can i resize a specific window after it's created?
body: <p>I want to resize some game window (DirectX) after it has been created, the game window allows resizing by mouse from the edges. But i want to automate this because it's quite hard to do this by mouse: cursor is invisible at the edges and i must de-focus the window first to be able to resize by clicking at the edges. To be clear: i have no sources for this game, so i must make my own program to do this.</p>
  
  <p>How can this be done? Or better: is there already existing programs to do these things?</p>
