ACC2000: Cannot Use New Visual Basic for Application Functions as Expressions (225956)


The information in this article applies to:

  • Microsoft Access 2000
This article was previously published under Q225956
Moderate: Requires basic macro, coding, and interoperability skills.

This article applies to a Microsoft Access database (.mdb) and to a Microsoft Access project (.adp).

SYMPTOMS

When you use one of the new Visual Basic for Applications functions as an expression, you may receive the #Name? error value. For example, if you set the ControlSource property of a text box to the expression =WeekdayName(6), the text box returns #Name? instead of the value Friday.

CAUSE

The FormatCurrency(), FormatDateTime(), FormatNumber(), FormatPercent(), InStrRev(), MonthName(), Replace(), Round(), StrReverse() and WeekdayName() functions are not supported as expressions.

RESOLUTION

Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. Create a custom function in a module that uses the built-in Visual Basic for Applications function. Then call this function where you need the expression. For example, create the following function: 
Function MyStrRev(strRev)
   MyStrRev = StrReverse(strRev)
End Function
After you have created the function, set the ControlSource property of the text box to =MyStrRev("abcd").

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
