// 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.
