Although the steps to create the sample macro are written for Microsoft Excel, the code can be used in other programs that support the Visual Basic for Applications programming language and the Visual Basic Editor.

NOTE: Because the macro in this example deletes the module that contains it, store procedures that you want to keep in a separate module.

1. Start Microsoft Excel, and then create a new workbook.
2. Press ALT+F11 to start the Visual Basic Editor.
3. If the Properties window is not visible, click Properties on the View menu (or press F4).
4. If the Project Explorer window is not visible, click Project Explorer on the View menu.
5. On the Insert menu, click Module.
6. In the Properties window, change the (Name) property of the module to TestModule.
7. Type the following code into the module:

         Sub DeleteAfterRun()
   
            Dim x As Object
   
            ' This is the code that I want to run once.
            MsgBox "Hello, World!"
   
            Set x = Application.VBE.ActiveVBProject.VBComponents
   
            ' Delete the current module.
            x.Remove VBComponent:=x.Item("TestModule")
   
         End Sub
   						

8. Press ALT+F11 to switch to Microsoft Excel.
