CPropertySheet::GetActivePage
Retrieves the property sheet window's active page.
CPropertyPage* GetActivePage( ) const;
Return Value
The pointer to the active page.
Remarks
Use this member function to perform some action on the active page.
Example
// 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.
