title: Embed Word document preview in WinForms app
body: <p>How can I embed a word document in a form or usercontrol like the explorer preview panel does?</p>
  
  <p>I found <a href="http://social.msdn.microsoft.com/Forums/en/csharpgeneral/thread/127bd801-525d-41c3-8516-cac7c68ec43b" rel="nofollow">this topic</a> and they say DSOFramer isn't available any more, but what should I use now? A third party tool is only acceptable if its free.</p>
  
  <p>The only thing I noticed was that prevhost.exe starts a winword.exe process with the -Embedding command switch, but I can't find any information on this switch.</p>
