// Retrieving the class id

hr = CLSIDFromProgID(L"TDOLEDB", &clsid);

hr = CoCreateInstance(clsid, 

                      NULL, 

                      CLSCTX_INPROC_SERVER, 

                      NULL, 

                      IID_IDBInitialize, 

                      (IUnknown **)&pIDBInitialize);
