Referencing controls

[Edneeis]

Why does the code need to be in a module? How many constituent controls are there on the Usercontrol?

For that you'd probably have to make your own control collection although that wouldn't be difficult.

You could either pass the controls collection as an object:

'in module
Public Sub PassCol(obj As Object)
    Dim ctrls As Object
    Set ctrls = obj
    Dim ctrl As Control
    For Each ctrl In ctrls
        MsgBox ctrl.Name
    Next
End Sub
 
'in usercontrol
PassCol Controls

Or if you don't want to use the generic object then put all the controls in your own collection:

'in module
Public Sub PassCol(col As Collection)
    Dim ctrls As Collection
    Set ctrls = col
    MsgBox ctrls.Count
End Sub
 
'in usercontrol
    Dim col As New Collection
    Dim ctrl As Control
    For Each ctrl In Controls
        col.Add ctrl
    Next
    PassCol col
