SETP1: Add an inheritance class for an ATL interface class
Yourinterface.h
Class ATL_NO_VTABLE CYOURINTERFACE: PUBLIC IOBJECTSAFETYIMPL
Setp2: Add MAP
Begin_COM_MAP (CYOOURINTERFACE) COM_INTERFACE_ENTRY (IOBJECTSAFETY) END_COM_MAP ()
SETP3: The resell definition increases the following two member functions can be registered by safe registration software.
