Introduction

The ADO data control presents a fast and easy way to create a bound form by providing
built-in functions that define, navigate, display, add to, and update the records in a recordset.
The resulting form makes it easy for a user to maintain records. Although the data control
defines the record set, you’ll still need a control for each field to automatically display the
bound records.
