How to get a macro to make sure its not in this workbook, but will work in the active workbook?

I want my formatting macro to run on a different workbook than the one the macro is stored in. So far I have only this code:

Application.ScreenUpdating = False

If ActiveWorkbook.Name <> ThisWorkbook.Name Then
--Do the things i want--
End If

Do i need to have the Dim ___ As things to go with it?
