Retrieves a pointer to the requested interface.
static HRESULT InternalQueryInterface( void* pThis, const _ATL_INTMAP_ENTRY* pEntries, REFIID iid, void** ppvObject );
InternalQueryInterface only handles interfaces in the COM map table. If your object is aggregated, InternalQueryInterface does not delegate to the outer unknown. You can enter interfaces into the COM map table with the macro COM_INTERFACE_ENTRY or one of its variants.
