[perl-win32-gui-users] get value from list

[Michael Solomon]

I am querying a database and putting the output into a listview

What I would like to next is to click on an item in the list and then
drilldown into the data base

The question is how can I return the value from a List

I am fairly new at using Win32::GUI and apologise if this is a stupid
question.

Should I be using a different type than listview and if so what should I be
using?
