title: Highlight text from Visual Studio 2008 add-in
body: <p>I'm writing another code coverage tool for .NET with Visual Studio 2008 integration.<br>
  Everything goes well except one thing: I can't find a way to highlight some code chunks.</p>
  
  <p>I need it to inform user about covered and not covered blocks.<br>
  You can see example of the feature I want on the next screenshot (from native VS code coverage toolset):</p>
  
  <p><a href="https://i.stack.imgur.com/fOUDy.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/fOUDy.jpg" alt="Coverage Example"></a></p>
  
  <p>Can someone provide me a code snippet that highlights text in the code view window?<br>
  Links to appropriate MSDN articles related to VS2008 are also appreciated!</p>
  
  <p>Thanks in advance.</p>
