The CRecordset represents a set of records obtained from a data source through a query. If no records from the data source match the query, there will be no records in the record set object so CRecordset::IsEOF and CRecordset::IsBOF both return a nonzero value. A query is executed during calls to CRecordset::Open and CRecordset::Requery, so empty record sets can be detected calling CRecordset::IsEOF and/or CRecordset::IsBOF after executing a query.
This behavior is described in the documentation for CRecordset::IsEOF and CRecordset::IsBOF.
