// 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
