Error with Evaluate with More Than One Custom Function

WORKAROUND

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. To work around this problem, break the Evaluate statement up into sections that only have one custom function call per section.

The following example takes the string "MyFunc()+MyFunc()" and illustrates how it could look using the workaround. Because MyFunc is a custom function call, it needs to be evaluated in two separate EVALUATE statements.

Sample Visual Basic Procedure

1. Type the following code on a new module sheet:

         Sub Example()
             MsgBox Evaluate("MyFunc()") + Evaluate("MyFunc()")
         End Sub
   
         Function MyFunc()
             MyFunc = 1      ' Return a value of 1.
         End Function
   						

2. Run the Example macro.
   
   Note that a message box with the number 2 is displayed.
