HOWTO: Detect an Empty CRecordset Object

Last reviewed: July 31, 1997
Article ID: Q121950

The information in this article applies to:

The Microsoft Foundation Classes (MFC) included with:

    - Microsoft Visual C++ for Windows, versions 1.5, 1.51
      Microsoft Visual C++, 32-bit Edition, versions 2.0, 4.0, 4.1,
      4.2, 5.0

SUMMARY

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.

REFERENCES

This behavior is described in the documentation for CRecordset::IsEOF and CRecordset::IsBOF.
