Create a HasValue Function in Microsoft Access VBA to Check Null, Empty Values

Create a HasValue Function in Microsoft Access VBA to Check Null, Empty Values In this Microsoft Access tutorial, you will learn how to create a custom HasValue function using VBA. This function is specifically designed to check for empty and null values in short and long text fields. This function is great for when you don't know what type of field you're dealing with, and you're tired of always checking for both. Mason from Schaumburg, Illinois (a Platinum Member) asks: How can I understand the difference between an empty value and a null value in Microsoft Access? I have a button on a form to check if a field is blank, but when a user deletes a value in a record, I noticed that the behavior differs for short text fields (which become null) and long text fields (which become empty). Can you explain what's going on?
