Bonnie,

I'm not sure that's the right answer, although I don't know for sure myself. Maybe Kevin will answer us better.

I know that when you use MM and create a form you create it from an MM template which is an MM class. I think the real question is is how to subclass the MM classes.

Things like Forms can be sub-classed visually ... add a Form to your project (right-click, add new Item, choose a Form), then simply go to the code and change:

>(I don't use MM, so I don't know what the proper name of the form is).

>using System.Collections;
>using System.ComponentModel;
>using System.Windows.Forms;
