BeforeUpdate & AfterUpdate By Richard Rost ![]() ![]() BeforeUpdate & AfterUpdate in Access: Conflict Check In this Microsoft Access tutorial I will show you how to use the BeforeUpdate and AfterUpdate events together to prevent double-booking appointments, validate user input for valid dates and times, and prompt for sending a confirmation email after an appointment is added. We will build a simple appointment form, check for date conflicts, and add useful validation to make sure appointments are entered correctly. Bryce from Mesa, Arizona (a Platinum Member) asks: I have a form where I schedule appointments, and I only book them on the hour, like 10am or 3pm. Is there an easy way to check if I already have something scheduled at that time so I don't double-book? Also, after I enter the appointment, can Access prompt me to send a confirmation email? I keep forgetting to do that, and it would really help if the system reminded me automatically.
