Enumerate controls on a form

While enumerating the controls on a form when I reach a control that is
set-up as a control array I cannot determine which array element it is.
Below is the code I'm using:

For Each ctlControl In Me.Controls
Printer.Print ctlControl.Name & vbtab & TypeName(ctlControl)

I get the name of the control but not the index number of the item when it
is a control array.

Any suggestions or thoughts?
