Tod,

Look at the UserControl property. E.g.,

If Application.UserControl = True Then
MsgBox "Hello, World"
End If

Is there a way to show a msgbox only if the user opens the
workbook? The workbook is also opened by a script to
update some data. I don't want the msgbox code to run if
the workbook is opened from the script.
