// COleInPlaceObject::QueryInterface
//
// Purpose:
//      Used for interface negotiation
//
// Parameters:
//
//      REFIID riid         -   Interface being queried for.
//
//      LPVOID FAR *ppvObj  -   Out pointer for the interface.
//
// Return Value:
//
//      S_OK            - Success
//      E_NOINTERFACE   - Failure
