CDaoRecordset::GetAbsolutePosition
Returns the record number of a recordset object's current record.
long GetAbsolutePosition( );
Return Value
An integer from 0 to the number of records in the recordset. Corresponds to the ordinal position of the current record in the recordset.
Remarks
The AbsolutePosition property value of the underlying DAO object is zero-based; a setting of 0 refers to the first record in the recordset. You can determine the number of populated records in the recordset by calling GetRecordCount. Calling GetRecordCount may take some time because it must access all records to determine the count.
If there is no current record, as when there are no records in the recordset, – 1 is returned. If the current record is deleted, the AbsolutePosition property value is not defined, and MFC throws an exception if it is referenced. For dynaset-type recordsets, new records are added to the end of the sequence.
Note
This property is not intended to be used as a surrogate record number. Bookmarks are still the recommended way of retaining and returning to a given position and are the only way to position the current record across all types of recordset objects. In particular, the position of a given record changes when record(s) preceding it are deleted. There is also no assurance that a given record will have the same absolute position if the recordset is re-created again because the order of individual records within a recordset is not guaranteed unless it is created with a SQL statement using an ORDER BY clause.
Note
This member function is valid only for dynaset-type and snapshot-type recordsets.
