DotNetMania,

You can call the InternetGetConnectedStateEx function in the WinInet
library through the P/Invoke layer to do this. You can use this code:

[DllImport("WinInet.dll", CharSet=CharSet.Auto)]
public static extern bool InternetGetConnectedStateEx(
[MarshalAs(UnmanagedType.U4)] int lpdwFlags,
StringBuilder lpszConnectionName,

[MarshalAs(UnmanagedType.U4)] int dwNameLen,
[MarshalAs(UnmanagedType.U4)] int dwReserved);

You can get the values to pass in from the documentation for this
function.

Hope this helps.
