Automatically size / resize combo box

Hi All,

I'm creating a form and am interested to know if there is a way to easily
size a combo box to the width of its possible values. I'd like to be able
to add a combo box control to a form in design view, then format it such
that its width will increase or decrease based on the possible values.
Also, if the user adds a longer value than what the control initially has in
its list, I'd like the width to increase to accommodate it.

Any & all help is appreciated.

Thanks & Ciao,

Tony
