How do you check if webclient.downloaddata is working? I mean what if the site you are trying to access suddenly turns down. How do you avoid getting an error? Below is an example code:

Dim webclient As New WebClient

Dim eIP As String

eIP = System.Text.Encoding.ASCII.GetString((webclient.DownloadData("http://www.vbdotnetforums.com")))

Label1.Text = eIP

WebClient.DownloadData Method (String) (System.Net) see what it says in Exceptions section.
