Procedures that Act on a Group of Controls

You can use the almost-forgotten ability of Visual Basic to have a function or sub with an undetermined number of arguments do something to a set of controls. For example, you can enable/disable many controls with one sub call:
 
EnableAll True, Text1, Text2, _
        Command1, Command2
This procedure iterates on all the controls passed as arguments:
 
Sub EnableAll(Enabled As Boolean, _
        ParamArray objs() As Variant)
                Dim obj As Variant
                For Each obj In objs
                        obj.Enabled = Enabled
                Next obj
End Sub
