XL5: Can't Define Name with Same Name as a Subroutine

ID: Q111281


The information in this article applies to:
  • Microsoft Excel for Windows, versions 5.0, 5.0c
  • Microsoft Excel for the Macintosh, versions 5.0, 5.0a


SYMPTOMS

In Microsoft Excel version 5.0, you cannot define a new name that is the same as the name of a currently running Microsoft Visual Basic for Applications subroutine. If you attempt to do so, you will receive the following error message:

Run-time error '1004':
Add method of Names class failed


STATUS

This is a known problem in Microsoft Excel 5.0. This problem was corrected in Microsoft Excel for Windows 95, version 7.0 and later.


MORE INFORMATION

When you run a Visual Basic subroutine, Microsoft Excel creates a temporary name for the subroutine in memory. As long as this temporary name exists, it is not possible to define a new name that is the same as the temporary name. You can, however, redefine an existing name.

If you attempt to define a new name while an identically named subroutine is running, you will receive the error message shown above.

The following subroutines illustrate the various types of situations that may cause this error to occur. Enter the following subroutines into a new module sheet in a new workbook.

To run the subroutines, position the cursor in the Sub line for the subroutine you want to run and either press the F5 key or choose Start from the Run menu.

   'The Test1 subroutine will fail if the name "Test1" does not already
   'exist in the workbook.

   Sub Test1()
     
       ActiveWorkbook.Names.Add Name:="Test1", _
           RefersToR1C1:="=Sheet1!R1C1:R10C10"

   End Sub

   'The Test2 subroutine runs the MakeName subroutine, which attempts to
   'define the name "Test2". As with the above subroutine, it will fail if
   'the name "Test2" does not already exist in the workbook.

   Sub Test2()
       MakeName                              'runs the Test2 subroutine
   End Sub

   Sub MakeName()
     
       ActiveWorkbook.Names.Add Name:="Test2", _
           RefersToR1C1:="=Sheet1!R1C1:R10C10"

   End Sub
