disbale network from c#

[yaniv]

I build an app and i want it to block surfing when a "user" didn't chose, but I can�t find a way to stop the network adapter from c#. I saw and tried a lot of examples and advices from all other the net, but none worked for me. I tried to disabled the adapter-

public void DisableNetWork(string interfaceName)

{

SelectQuery wmiQuery = new SelectQuery("SELECT * FROM Win32_NetworkAdapter WHERE NetConnectionId != NULL");

ManagementObjectSearcher searchProcedure = new ManagementObjectSearcher(wmiQuery);

foreach (ManagementObject item in searchProcedure.Get())

{

if (((string)item["NetConnectionId"]) == "Local Area Connection")

{

try

{

item.InvokeMethod("Disable", null);

 

}

catch (Exception ex)

{

String s = ex.Message;

}

 

}

}

}

 

I tried socket bind to another process, so I can block the browsers, I tried disabling the drivers, but nothing worked so far. Do you any have working working idea for me? If you have, Please check if it working on win7 since I understood that there is a different between XP and 7.

 

Great thanks
