Hi,

You can use the API function InternetCheckConnection to achieve this:

Sample Code below:

Hi

I don't like linking to dll's as this causes no end of deloyment headaches + security exception issues.

This works in c#

using System.Net;

HttpWebRequest request = (HttpWebRequest)WebRequest.Create( url );

You simply get exceptions when Create is called.

It's part of the framework and requires no horrible external dll calls.
