vb6 List Box Double-Click Problem

Here is a problem for the old sages...I have a vb6 app that I am upgrading.  It has a list box with a list of data of varying number.  It is basically a list of participants in a race with their first name, last name, gender, etc.  What I want to do is be able to double-click on that list and have the data edit form come up as a modal form with that person's data populating the fields on that form.

Currently you have to open the edit form, find their unique ID in a drop down and click on that to get their data to populate.  I want to make the process quicker and easier.

Thanks a ton.  Best site ever for helping hacks like me...
