I'm trying to create a combo box that will allow the user to enter an email
address in the combo box and select the domain portion from the list (@ and
forward). I have gotten as far as being able to pick from the list and concatenate
the domain to the end of the entered text but I've been unable to emulate
the text completion portion. e.g. I want to be able to hit the @ and have
the first selection in the list be placed at the end of the entered text.
In short, I want to code standard bound combo box functionality.

Any examples out there.
