You do not have to instantiate objects of this class directly.
Because it is a base class for all visual managers, you can just call CMFCVisualManager::GetInstance, obtain a pointer to the current Visual Manager, and access the methods for CMFCBaseVisualManager using that pointer. However, if you have to display a control by using the current Windows theme, it is better to use the CMFCVisualManagerWindows interface.
