Powerpoint addin : How to manage context across multiple open documents ?

I have created a Powerpoint VSTO add-in using C#.

In add-in, I have created a ribbon (using XML) that provides a Login button.

When a user clicks the login button

  • The login form is displayed
  • The user enters his credentials
  • If credentials are correct, the login button changes color and displays username to denote that the user is logged in
  • Few more ribbon buttons are made visible to allow the user to access data from the server and download it in the ppt.

My issue is :

  • I open one ppt document and log in. Ribbon UI is updated
  • If I open a second ppt document, ribbon UI shows that I have already logged in. This is invalid.

How can I contextualize the ribbon state across different presentation documents?
