combo box auto complete

["HaB JacKaL" <feelthel0ve hotmail com>]

Hello..

I am writing a customer management/inventory app.  I am currently working on 
the order entry screen, and was wondering what the best way to proceed on 
this is:

I want to have the customer last name field be a combo box, such that when 
the user begins typing in it, it will re-populate itself using only the 
entries that match the typing.  For example: you have these names in your 
customer list:

Smith
Smithson
Smithers
Smyth
Smitty

The user types 'sm' and there's no change, they type 'i', and 'smyth' 
disappears, they type 'smith' and smitty disappears also.

Basically the same way most web-browsers auto complete the address field.  
(Opera 5 for linux, or IE and NS on Windows), except once a user tabs away 
from this field, it will populate the rest of the form if they selected an 
already existing entry.

Any advice?  Has it already been done somewhere?  What events should I be 
listening for?

Thanks...
