Another complication: When the workbook is protected, the line:
With ActiveWorkbook.VBProject.VBComponents("UserForm1") .CodeModule
causes a run-time error. I really need to trap the TextBox change events
with the VBA code protected.

I need to create event procedures for controls added with Controls.Add.
The following approach was suggested:

Private Sub UserForm_Activate()
Dim Ct As Control, StartLine as long

Set Ct = Me.Controls.Add("Forms.TextBox.1", "txtNew" , True)
With ActiveWorkbook.VBProject.VBComponents("UserForm1") .CodeModule
StartLine = .CreateEventProc("Change", Ct.Name) + 1
End With

But I get a runtime error on the .CreateEventProc call - Error 57017 "Event
handler is invalid"

Where have I gone wrong? Are there any other approaches (such as control
arrays in VB6)

Many thanks,
