To mix OLE DB consumer templates and Active Data Objects (ADO), use ADO to open a recordset (corresponding to a rowset in the OLE DB Consumer Templates). When you have a recordset, do the following to connect to an OLE DB rowset:
Call QueryInterface for the IRowset and IAccessor pointers.
IRowset* lpRowset = NULL; IAccessor* lpAccessor = NULL; lpUnk->QueryInterface(IID_IRowset, (void**)&lpRowset); lpUnk->QueryInterface(IID_IAccessor, (void**)&lpAccessor);Note
lpUnk points to the IUnknown object of the ADO recordset.
Attach the accessor and rowset to their appropriate OLE DB consumer template classes.
CRowset rs; CAccessor accessor; accessor.AddAccessorInfo(0ul); // 0 is the ordinal of an ADO accessor rs.m_spRowset.Attach(lpRowset); // use the Attach method of CComPtr<> rs.SetAccessor(accessor);
