Re: Hiding tab control for CTabView

In my case, I want to have a "hidden" configuration view.  I hook the keyboard and show the view on F2.  I don't need a tab control per se, but that seems like the easiest way to manage this.

In the past using MFC, I had an app with many views.  Depending on what was clicked in what view, a new view would fill the frame.  I used something similar to EkSwitchViewInFrame() from the MFC Answer Book.
