// The code fragment below sets the last active page (i.e. the  
// active page when the propertysheet was closed) to be the first  
// visible page when the propertysheet is shown. The last active  
// page was saved in m_LastActivePage, (a member variable of  
// CDocument-derived class) when OK was selected from the  
// propertysheet. CMyPropertySheet is a CPropertySheet-derived class.
