DATA Control

Data Control caption Get first Get previous Get next Get last

A DATA control on a form points to one table in a database. A DATA control accesses data, it does not display it We need to BIND label controls and text controls to the data control in order to display the data

To look at one field in one table in one database: 1. Put one data control and one label control on the form. 2. Specify database by setting data control’s “database name”. 3. Specify database table by setting data control’s “record source”. 4. Bind the label control to the data control by setting the label control’s “data source”. 5 Select the database field to display by setting the label control’s “data field”. 6 Run the project and browse the database.

DATABASE NAME - name of database RECORD SOURCE - table name RECORD SET - all records in table Recordset.MoveFirst - go to top of table Recordset.MoveLast - go to bottom of table Recordset.MoveNext - go to next record Recordset.MovePrevious - go to previous record Recordset.BOF - beginning of table Recordset.EOF - end of table
