title: Attaching button to existing application (AutoIT)
body: <p>I have an existing .exe program (not mine so I can't edit it) that runs in a window of static size. What I want to do is overlay an extra button (preferably an image in the same style) on top of this window at specific coordinates within that window (and it has to move with the window if dragged elsewhere) to expand on it's functionality.</p>
  
  <p>How do I go about this? I have searched for quite a bit, but wasn't able to find anything. I was able to create a Parent-Child in AutoIT itself, but cannot seem to attach a child to an existing application.</p>
