Comments
CUnknownObject overridable. Derived classes should override this method to respond to their own interfaces. You will find that the base class CctlPropertyPage implementation of InternalQueryInterface is sufficient for most cases. If you do override this method, then you will be required to call CCtlPropertyPage::InternalQueryInterface for any interfaces that your property page does not support.
