You can use the HttpWebRequest and HttpWebResponse objects from System.Net to communicate with a webserver.

e.g.

string GetWebPage(string address)
{
    string responseText;
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(address);

    using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
    {
        using (StreamReader responseStream = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding("utf-8")))
        {
            responseText = responseStream.ReadToEnd();
        }
    }

    return responseText;
}

You can then set the text of your textbox using:

myTextBox.Text = GetWebPage(address);

To make things nicer for your users, you should make the web requests asynchronous, so you don't lock up the UI while the data is downloading. You could use a BackgroundWorkerThread to do this.

This is the error message i am getting The remote server returned an error: (401) Unauthorized.

The 401 error is because the website requires authentication - e.g. a username and password. If you visit the website in a normal browser does it prompt you to login?
