XL98: "Invalid Use of Null" Error Setting OnRepeat Method (184175)

RESOLUTION

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. In earlier versions of Microsoft Excel, you can set the parameters of the OnRepeat method to Null and not receive an error. If you set the OnRepeat argument to Null, you reset the action that occurs when the user selects the Repeat command on the Edit menu.

The following macro runs successfully in Microsoft Excel version 5.0 but fails in Microsoft Excel 98:

    Sub Test()

        MsgBox "Hello World!"

        ' Reset the Repeat command
        Application.OnRepeat Text:=Null, Procedure:=Null

   End Sub
				

To correct this problem so that the macro runs without error, set the OnRepeat arguments to empty string values instead of Null:

  Sub Test()

        MsgBox "Hello World!"

        'Reset the Repeat command
        Application.OnRepeat Text:="", Procedure:=""

   End Sub
