I plan to create a simple application using the help of Microsoft Visual C# 2008 edition. I have a listbox where I place a bunch of URLs. I also have two textboxes on the form for username and password. I want to make a modification, so that whenever I click an item on the listbox, the textboxes will update and modify automatically. Is this possible to get it done? I really think it would be a good addition to the site. Please let me know if you have any suggestions on this matter.

Thanks a lot for your advice
