Good point, Gianluigi.

The inherited class, UserControl, does not implement a Change event.

I was merely trying to quickly solve the issue of the appropriate event handler being called. Now that I've taken a closer look 
at it, it appears that the event name of the TextBox does not need to be unique. Simply making the name of the popup menu unique 
is sufficient.

To make a Change event work:
1) Leave the line that creates the TextBox as: $hText = New TextBox($hContenedor) As "CajaTexto"
2) In the clastextbox class header, add: Event Change()
3) Implement an event handler in the class for the CajaTexto_Change() event:
Public Sub CajaTexto_Change()
   Raise Change()
End

This allows the parent form to handle the change event of each distinct clastextbox object.
