When working with a database system, the same tasks may be performed repeatedly. Instead of doing the same steps each time, you can automate the process with VBA.

Database management systems continually grow as you add records in a form, build new queries, and create new reports. As the system grows, many of the objects are saved for later use — for a weekly report or monthly update query, for example. You tend to create and perform many tasks repetitively. Every time you add contact records, for example, you open the same form. Likewise, you print the same form letter for contacts that have purchased a vehicle in the past month.

You can create VBA code throughout your application to perform these tasks. The VBA language offers a full array of powerful commands for manipulating records in a table, controls on a form, or just about anything else. This chapter continues the previous chapters' discussions of working with procedures in forms, reports, and standard modules.
