Employee Form

A typical requirement for a database application is to allow the user to view data in the database. Our example employee form has the following four buttons that let the user scroll through data:

Button	Function
|<	Moves to the first record
<	Moves to the previous record.
>	Moves to the next record.
>|	Moves to the last record.

To navigate through the records of the employee database, we first create a global dynaset that selects all the records (rows). We then use one of the following dynaset move methods to code the navigation button:

Method	See...
DbMoveFirst	Moving to First and Last Rows
DbMovePrevious	Moving to the Previous Row
DbMoveNext	Moving to the Next Row
DbMoveLast	Moving to First and Last Rows
