unsigned m_bReset:1;
Remarks
A bit flag used to determine if the cursor position is defined on the rowset. If the consumer calls GetNextRows with a negative lOffset or cRows and m_bReset is true, GetNextRows moves to the end of the rowset. If m_bReset is false, the consumer receives an error code, in conformance with the OLE DB specification. The m_bReset flag gets set to true when the rowset is first created and when the consumer calls IRowsetImpl::RestartPosition. It gets set to false when you call GetNextRows.
