CboBox form Filter Question!

Hi all, I must say you have all been great in this newbie project I
have been working on.

I have but one last queestion. I have a bound form to lets say
Tbl_Companies. On this form holds an Unbound listbox with a phone book
filter similiar to Northwind, #, A,B,C....All Records, Which this works
very well.

What I would like to know is how I filter the form from a combo box.
The combo box holds the fields for my company types, (General
Contractor, Subcontractor, Architect, Client...), which would filter
down the amount of companies in the listbox but still have the
phonebook control to filter through the A,B,C's.... of that selected
CboCompany selected!

While I am at it, I would also like a txtBox wher I could lets say type
in a company Name and it would filter that name or names like that to
my listbox.

Any help would be much apriciated!

Thanks to all.
