Ad Rotator HELP!

Ok say i have a program it is going to be free to use so i want to be able to display ads in it like AOL does for dell(down at the bottom of the screen. I want it to automatically rotate throught about 10 ads every 15 minutes or so. I know there is an ad rotator thing in vb.net but i can not use it with my form, for some reason it only works with web forms and mine is a windows form so i need something other than that, i think it can be done with XML but i am not the best in that area so if someone could help me out or give me a site with examples and help that would be good to Thanks!

Where were you planning on getting the ads from? Would they be local or on a server?

In vb6 I used to just add a webbrowser control that connected to a random cgi script, that way mouseovers, banner rotation and links to the sponsor were all handled by it rather than the software. Of course then the software would only display ads while the user was online, but I only used that for online apps.
