I made a cybercafe application where the internet connectivity is a vital issue.I want to disable internet connection until any user login in my application.
At first the task is done by disable the Proxy server.But this is not perfect solution for me because my user use mozilla firefox and the browser facilitates some network settings just like use no proxy,use system proxy,auto detect proxy or manually configure
proxy.So when any user change this settings to system proxy to no proxy then my application fail to stop them browsing.
I want to stop browsing after their limited time.
Please give me some example.I made this application using C# WPF,sql server 2008.
