void MoveFirst( );
throw( CDaoException, CMemoryException );
Remarks
Call this member function to make the first record in the recordset (if any) the current record. You do not have to call MoveFirst immediately after you open the recordset. At that time, the first record (if any) is automatically the current record.
Caution Calling any of the Move functions throws an exception if the recordset has no records. In general, call both IsBOF and IsEOF before a Move operation to determine whether the recordset has any records. After you call Open or Requery, call either IsBOF or IsEOF.
If you call any of the Move functions while the current record is being updated or added, the updates are lost without warning.
Use the Move functions to move from record to record without applying a condition. Use the Find operations to locate records in a dynaset-type or snapshot-type recordset object that satisfy a certain condition. To locate a record in a table-type recordset object, call Seek.
If the recordset refers to a table-type recordset, movement follows the table’s current index. You can set the current index by using the Index property of the underlying DAO object. If you do not set the current index, the order of returned records is undefined.
If you call MoveLast on a recordset object based on an SQL query or querydef, the query is forced to completion and the recordset object is fully populated.
You cannot call the MoveFirst or MovePrev member function with a forward-only scrolling snapshot.
To move the position of the current record in a recordset object a specific number of records forward or backward, call Move.
For more information about finding records, see the article DAO Recordset: Recordset Navigation in Visual C++ Programmer's Guide. For related information, see the topics "Move Method" and "MoveFirst, MoveLast, MoveNext, MovePrevious Methods" in DAO Help.
