webbrowser control [UNRESOLVED]

[kleinma]

I have been looking for an answer to this for a long time, but I still have yet to come up with any solution.

My application has a webbrowser control in it. This control is used to get information from our website to give to the end user. The end user never actually sees the data in the webbrowser control because it is on a hidden form. For example, this program needs to be activated on our server for them to use it. When they put the cd key in, it sends it as a parameter on a url to our website which validates it and returns a good or bad response. the response is read in and if good they continue, if not it haults the application.

so my problem is that people with firewalls seem to be having trouble getting this to work. I would think since this is the webbrowser control, that if they can get out to the internet with internet explorer, then my app should be able to do the same, but for whatever reason, this is not the case. I tried installing zonealarm to replicate the problem, and when i get the popup authorizing access, it tells me the destination IP is 127.0.0.1 with a different port number each time. Why it is using this IP is odd to me, and why its not working is a bigger mystery.

Is there a better method I can use to navigate to webpages? Why wont this work in my app?
