title: C# : Closing a windows form on excel closing event
body: <p>My situation is that I'm developing a C# application which is launching an instance of a Microsoft Office Excel Application.<br>
  I change some of the Form's functions so that the instantiated Excel Application is being killed and cleaned up from memory when my Form's being closed.</p>
  
  <p>What I want to do is to perform the opposite. I'd like my instance of Excel to close my windows Form when it's being exited.</p>
