title: Set Owner of wpf window by window of other application, is it possible?
body: <p>I would like to make an application by wpf which could overlay a specific windows application.
  It means, when I run my application and specify Notepad as target application. At that time, anytime Notepad application got focus, my application will take over the focus &amp; prevent user handle directly Notepad.</p>
  
  <p>It is quite simple in case of 2 windows in same application ( we can set owner of child window &amp; showdialog)</p>
  
  <p>So, I wonder that if it is possible to get the handle of window of other application to set owner for our application.</p>
  
  <p>Thanks for any comments or discussion!</p>
