title: Debug PowerPoint VSTO Add-In with opening a file by default
body: <p>In my PPT Add-In there is a bug where I don't run some initialization properly when you double-click a PPT file. This initialization is enabling certain button on the ribbon and should be done when the first presentation is opened (and the buttons are disabled when the last presentation is closed).</p>
  
  <p>I can also reproduce the issue if I open <code>POWERPNT.EXE</code> with <code>/O FileName</code> arguments.</p>
  
  <p>What I cannot do is start debugging with these command line arguments, since the Command line arguments I can set in the project settings does not seem to be delegated to <code>POWERPNT.EXE</code>.</p>
  
  <p>Is there a way to do this or do I need to fall back to phpesque debugging (a.k.a logging to console)?</p>
