// COleClientSite::QueryInterface
//
// Purpose:
//
//      Used for interface negotiation at this interface
//
// Parameters:
//
//      REFIID riid         -   A reference to the interface that is
//                              being queried.
//
//      LPVOID FAR* ppvObj  -   An out parameter to return a pointer to
//                              the interface.
//
// Return Value:
//
//      S_OK                -   The interface is supported.
//      E_NOINTERFACE       -   The interface is not supported
