ACC97: Error When You Click a Custom Command Bar Button

• Microsoft Access 97

SYMPTOMS

Moderate: Requires basic macro, coding, and interoperability skills.

When you click a menu or button on a command bar, you may see the following error message:

The expression you entered has a field, control or property name that Microsoft Access can't find.

CAUSE

This problem happens when the database has a long file name, and you assign a function using the following syntax:

   .OnAction = "=<function name>()" 

RESOLUTION

Do not include an equal sign (=) and parentheses (()) when you assign the function to the OnAction property of the command bar. For example, assign the OnAction property using the following syntax:

   .OnAction = "<function name>" 

STATUS

Microsoft has confirmed this to be a problem in Microsoft Access 97.
