title: how can I lock shapes in PowerPoint?
body: <p>I'm working on a Add-in for PowerPoint 2010 (C#) and I want to prevent the end-user to move or edit all the shapes that I have programmatically created. </p>
  
  <p>I have already sought in the framework but I think it's not allowed programmaticaly. Has anyone already encountered this kind of limitations and could help me to find a solution?</p>
  
  <p>I know that some people create their add-in thanks to C++ because there are a lot of limitations in office. </p>
