XL97: How to Display Custom Function in Function Wizard Step 2

ID: Q189165


The information in this article applies to:
  • Microsoft Excel 97 for Windows


SUMMARY

In Microsoft Excel 97 for Windows, you can create a custom Microsoft Visual Basic for Applications function to perform calculations. By default, this custom function will appear in the Function Wizard under the function category called "User Defined". You can call custom functions with the Function Wizard in Microsoft Excel just as you call built-in functions. However, there may be times when you want to use a Visual Basic for Applications macro to bypass step 1 of the Function Wizard and display a particular custom function in step 2 of the wizard. This article will demonstrate how to automatically show step 2 of the Function Wizard with a macro and have it populated with your custom function.

The following steps show you how to create a simple custom function and display this function in step 2 of the Function Wizard with a macro.

Create a Custom Function

To create a custom function, follow these steps:

  1. Close and save any open workbooks, and open a new workbook.


  2. Start the Visual Basic Editor by pressing ALT+F11.


  3. On the Insert menu, click Module.


  4. Type the following code into the module sheet:
    
          Function MyFunction(x As Integer, y As Integer, z As Integer) As Long
    
             MyFunction = x * y + z
    
          End Function 


  5. On the File menu, click "Close and Return to Microsoft Excel".


  6. Save this workbook as Test.xls.


Call the Function From Within the Workbook

To call this function from within Test.xls, type the following formula in cell A1 on Sheet1:
=myfunction(10,10,3)
Cell A1 should display the value 103, because the custom function multiplied x by y and added z (10*10+3).

Display the Custom Function With a Macro

In order to display the custom function with a macro follow these steps:

  1. Start the Visual Basic Editor by pressing ALT+F11.


  2. Type the following code into the module sheet:
    
         Sub CallStep2OfDialogWizard()
    
            ' Set location for the function.
            With Worksheets("Sheet1").Range("A1")
    
               ' Select cell A1.
               .Select
    
               ' Place custom function in cell.
               .Formula = "=myfunction()"
            End With
    
            ' Display step 2 of Function Wizard.
            Application.Dialogs(xlDialogFunctionWizard).Show
    
         End Sub 


  3. On the File menu, click "Close and Return to Microsoft Excel".


  4. Save the workbook as Test.xls.


  5. On the Tools menu, point to Macros, and click Macros. In the Macros dialog box, click to select "CallStep2OfDialogWizard", and then click Run.


  6. Type the following numbers for the X, Y, and Z function arguments in the wizard dialog:
    X: 10
    Y: 10
    Z: 3


  7. Click Ok.


Cell A1 should display the value 103, because the custom function multiplied x by y and added z (10*10+3).
