Hi i am writing a simple app with doc/viw architecture, now i have to buttons in the Outlook bar "Folders" and "Calendar" now i want that when restart the app the selected pane will be always the 0 -> "Folders" now i tried this:

CMFCOutlookBarTabCtrl\* pOutlookBar = (CMFCOutlookBarTabCtrl\*)m\_wndNavigationBar.GetUnderlyingWindow();

pOutlookBar->SetActiveTab(0);
