Using the KeyPress Event to Allow or Disallow Specific Characters in Microsoft Access

In this Microsoft Access tutorial, I will show you how to enforce data entry rules for names, ensuring only capital letters A-Z are allowed in fields, without special characters or spaces. We'll utilize the key press event and VBA code to restrict unwanted characters, providing you with a robust solution for maintaining data integrity.

Sadie from Alpharetta, Georgia (a Platinum Member) asks: My client is very strict about how names are entered in our database. For the First Name and Last Name fields, they only want capital letters. No spaces, no apostrophes, no special characters, or numbers. Just A-Z and nothing else. Is there a way to enforce this in Microsoft Access? Can this be done with just an input mask, or do I need to use VBA?
