title: Programmatic access to Ribbon controls in VSTO
body: <p>I am writing C# with VSTO in Visual Studio 2008 in order to create an add-in for Office 2007.</p>
  
  <p>After I have defined a custom ribbon tab using XML, how do I obtain references to the various controls in the Ribbon?  I would like to be able to do things like programatically manipulate the content of an EditBox.</p>
