XL98: Error Getting the Value of a Name in Visual Basic

ID: Q191161

The information in this article applies to:

Microsoft Excel 98 Macintosh Edition

SYMPTOMS

In Microsoft Excel, you may receive the following error message when you use the Visual Basic Range(Name).Value method to get a value based on a defined name:

   Run-time error '1004':
   Range method of Application class failed

CAUSE

This error message occurs if the defined name in question refers to a constant value or a formula rather than a range.

This behavior is by design of Microsoft Excel.

RESOLUTION

To prevent the error message from appearing, use the Evaluate method to determine the value of the defined name. Please see the "More Information" section of this article for an example that demonstrates this issue.

MORE INFORMATION

If a particular defined name will refer to a constant value or a formula, you can use the .Evaluate(Name) method to get the value of the name. The .Evaluate(Name) method can evaluate formulas and constant values even if they don't refer to an actual range.

However, note that the .Evaluate(Name) method may return an error message if the name refers to an error value, such as #REF! or #N/A. In these cases, you may need to employ error checking (such as the On Error Resume Next function) or use an alternative method, such as the Names(Name).RefersTo method, to detect or handle an error value.

For example, if you have a sheet named Sheet1 in a workbook that contains the following global names

   Name     Refers to               Cell information
   ---------------------------------------------------------------
   Alpha    =Sheet1!$B$1            Cell B1 contains the number 1
   Bravo    =2
   Charlie  =SUM(Sheet1!$B$3:$C$3)  Cell B3 contains the number 3,
                                    cell C3 contains the number 4
   Delta    =Alpha
   Echo     =Charlie
   Foxtrot  =Alpha+Charlie
   Golf     =#N/A

and you use the Range(Name).Value and .Evaluate(Name) methods to get the values of the names you will receive the following results in your macro:

   Name     Range(Name).Value     Sheets("Sheet1").Evaluate(Name)
   --------------------------------------------------------------
   Alpha    1                     1
   Bravo    [Error message 1]     2
   Charlie  [Error message 1]     7
   Delta    1                     1
   Echo     [Error message 1]     7
   Foxtrot  [Error message 1]     8
   Golf     [Error message 1]     [Error message 2]

The error messages 1 and 2 are as follows.

   Error message 1
   ---------------

      Run-time error '1004':
      Range method of Application class failed

   Error message 2
   ---------------

      Run-time error '13':
      Type mismatch

This article assumes that you are familiar with the programming language being demonstrated and the tools used to create and debug procedures. Microsoft support professionals 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 needs.

To check the value of a name, you can use the following subroutine:

   '----------------------------------------------------------------------
   Option Explicit

   Sub CheckNameValue()
      Dim Test As Variant
      Test = Range("Alpha").Value

      'To check the value by using .Evaluate(Name), use
      '
      '   Test = Sheets("Sheet1").Evaluate("Alpha")
      '
      'in place of the previous test line.

      MsgBox Test
   End Sub
   '----------------------------------------------------------------------

In order to prevent an error when the name refers to an error value (in this case, if the name is Golf), use the Names(Name).RefersTo method to check the name before getting its value. For example, you could use:

   Sub CheckForError()

      'If the name Golf refers to an error value, such as #REF! or #N/A,
      If IsError(Evaluate(Names("Golf").RefersTo)) Then
         'then show an error message to that effect,
         MsgBox "Golf is an error name!"
      Else
         'otherwise state that the name refers to a good reference.
         MsgBox "Golf is OK!"
      End If
   End Sub

If the name refers to an error value, the IsError test will be true and the error message box will be displayed. Otherwise, the OK message box will be displayed. For example, if the name is Golf, which refers to =#N/A, the error message box will be displayed. Using any of the other example names will result in the OK message box.
