Using the On Unload Event in Microsoft Access

In this Microsoft Access tutorial, I'm going to teach you how to use the On Unload event to perform data validation across multiple records and provide a friendly error message when you go to close a form in Microsoft Access.

Freya from Oslo, Norway (a Platinum Member) asks: I have a form where my employees enter a number of job codes for a particular project. Each job code is on a separate record. They have to enter at least five job codes but no more than eight. Is there any way I can check that before they're allowed to close the form?
