BOF, EOF Properties (ADO)

   Example   Applies To   

• BOF indicates that the current record position is before the first record in a Recordset object.
  
  
• EOF indicates that the current record position is after the last record in a Recordset object.

Return Value

The BOF and EOF properties return Boolean values.

Remarks

Use the BOF and EOF properties to determine whether a Recordset object contains records or whether you've gone beyond the limits of a Recordset object when you move from record to record.

The BOF property returns True (-1) if the current record position is before the first record and False (0) if the current record position is on or after the first record.

The EOF property returns True if the current record position is after the last record and False if the current record position is on or before the last record.

If either the BOF or EOF property is True, there is no current record.

If you open a Recordset object containing no records, the BOF and EOF properties are set to True, and the Recordset object's RecordCount property setting is zero. When you open a Recordset object that contains at least one record, the first record is the current record and the BOF and EOF properties are False.

If you delete the last remaining record in the Recordset object, the BOF and EOF properties may remain False until you attempt to reposition the current record.

This table shows which Move methods are allowed with different combinations of the BOF and EOF properties.

Allowing a Move method doesn't guarantee that the method will successfully locate a record; it only means that calling the specified Move method won't generate an error.

The following table shows what happens to the BOF and EOF property settings when you call various Move methods but are unable to successfully locate a record.
