XL: Error Getting the Value of a Name in Visual BasicLast reviewed: February 3, 1998Article ID: Q108517 |
The information in this article applies to:
SUMMARYIn Microsoft Excel you may receive an error message when you use the Visual Basic Range(Name).Value method to get a value based on a defined name. This error message will occur if the defined name in question refers to a constant value or a formula rather than a range.
MORE INFORMATIONIf a particular 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
This 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/Aand you use the Range(Name).Value and .Evaluate(Name) methods to get the values of the names you will receive the following results:
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 Sample Visual Basic ProcedureMicrosoft provides programming examples for illustration only, without warranty either expressed or implied, including, but not limited to, the implied warranties of merchantability and/or fitness for a particular purpose. This article assumes that you are familiar with the programming language being demonstrated and the tools used to create and debug procedures.

http://www.microsoft.com/support/supportnet/refguide/default.aspTo check the value of a name, you cah 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 SubIf 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.
