Is there a special message that I am not aware of being sent to my main window procedure that indicates a tab on a tab control being clicked on? (One of the tabs?) I've tried WM_LBUTTONUP messages, but no reaction when I click the tabs.

The tab control was created using the WS_CHILD style and is attached the main window of my program. I've looked on MSDN except that I can't seem to find a message sent for such an occurance, though I may be mistaken.

Any help would be greatly appreciated.
