Drop-down boxes in LabVIEW

[Arrington]

I'd like to offer my end user a drop-down box from which he can choose
one of ten model numbers.  I want to read those model numbers in from
a text file (ten lines, each with one model number).  Then I want to
display the user's choice on the front panel, as well as using it to
open up another text file whose name is the same as that model number
(plus the requisite .txt extension).  Thank you very much!
