I want to find the user's public IP address. To do this I am using a hidden WebBrowser control that navigates to http://www.whatismyip.com/. I then use a Regular Expression to get the IP. Every 10 minutes I want to check if the IP has changed.
Currently, I am using WebBrowserControl1.Refresh() to get the new IP but it does not work - I always get the IP that was found when the program first started. If I restart the program I get the new IP address.
How do I get the new content of the page rather than the old content
