If you have many property pages then the property sheet ends up showing multiple rows of tabs. Sometimes, the addition space required for the tabs is unacceptable. We can force the property sheet to use a single row of tabs by calling the CPropertySheet:: EnableStackedTabs(FALSE) before calling the DoModal() function.
Alternatively, the call to EnableStackedTabs() can be placed in the overridden version of OnCreate() in the CPropertySheet derived class. This call should precede the call to the base class version of OnCreate().
