webbrowser and proxy

i have a web browser on my form, and a list box with about 10 IP addresses.

How can i make it so that which ever IP is selected, it will use that for the proxy settings of that browser.

i know IE gets the settings from registry upon startup, but means i have to restart the form each time. any easier way?

I'm not sure if this would work but if you make your WebBrowser into a control array, you can load a new one like...

Load WebBrowser1(1)

then you can unload it when you've finished

Unload WebBrowser1(1)

this may stop you from having to relaunch.
