Programmatically setting focus to a tab

Hi,

I am using the Docking library, and I have a Tabbed MDI container with a tab in it. I have a button on my ribbon menu, that if the user clicks it, will add a new tab to the MDI container. This part works correctly, but I cannot figure out how to force the tab to come to the forefront as the "active" tab of the MDI container.

Thanks!
