CMFCOutlookBarTabCtrl::SetActiveTab not working

Question

I have added a CMFCOutlookBar control to a dialog. This outlookbar contains some 12 trees.

As per following link https://msdn.microsoft.com/en-us/library/bb983453.aspx we can set active tab (in my case tree control) of our wish.

but it doesn't seems to work.

as per above link this function returns non zero value on success. Indeed it is returning 1 when i used it to set tree of my choice. but visually it's not changed.

can someone help me?

Problem solved. CMFCOutlookBarTabCtrl::SetActiveTab() only works after window has been displayed. I guess this is because CMFCOutlookBar stores it's previous state to registory and reloads on next run. And this overrides changes made by SetActiveTab(), if we use it before displaying of window.
