There is sample code on this site for exactly that, but YOU have to look for it. Check out "Topic Areas: Internet" and "Contents: Tips", OR the "Search" engine on this site.

Aren't those types of connections always connected? Anyway, (it's been a while) but a crude way I've used is to add a Winsock control and call it's "Listen" method. Then check out the Local Port and Local IP. If they are both non-zero, then I believe that means you have an internet connection. Periodically you could close the socket and "Listen" again and recheck those Local properties.
I wrote a program using this technique to wait for my girlfriend to connect to the internet, then publish her IP and Port to my web site, while I would check my web site to see if the info was updated. Then I made a direct connection to her IP and Port and we would chat.
Hope that helps.

Nice idea, but if you are on the network then it will return your current IP Address. At the moment, the best way is to actually try and open a url and see if it fails. http://www.mvps.org/vb
