Newbie: Save and display multi-value listbox... (VB.NET)

I have a list box (i.e. FieldA) that allows the user to select more than one option. When saved, this field content is inserted in a table.

My questions are:
- How do i loop through this listbox and save the data. Do i need to concatenate the selected options into a string before or during saving?
- When this saved record is retrieved from the table, do i need to do anything in order to display the options that have previously been selected and saved?
I appreciate any coding that you can provide to assist me...

Try this article, it was helpful to me when I dealt with this same issue.
