I need to make a program that can open and read some simple data and make an association.

So for example the data would be something like this:

Name Phone number
Bob 408-911-9111
...
...

I want to be able only show the name in a listbox and once the user clicks on the name the phone number shows in a message box.

I handled it using a case statement, but unfortunately the case statement is getting WAY too big since there is about 30 items in the list (and there will be more). How can I do this using either an XML file or reading off a text file or something?

I don't have any DB programs btw.

Thanks
