Remarks
To specify an inherited interface, use index = 0. For a dispinterface with Syntax 2, call ICreateTypeInfo::AddImplType twice, once with index = 0 for the inherited IDispatch and once with index = 1 for the interface that is being wrapped. For a dual interface, call ICreateTypeInfo::AddImplType with index = -1 for the TKIND_INTERFACE type information component of the dual interface.
