title: How can I simulate a button click given the handle to the button's window?
body: <p>I want to simulate a click on a button located in a dialog box.</p>
  
  <p>I have the handle to that window. This is an Abort/Retry/Ignore kind of window. </p>
  
  <p>I don't want to go with simulating a click having X and Y coordinates as it doesn't suit my needs.</p>
