Hi,

While I am using the below code to get ipaddress of current localhost I am getting some error messages.

My code:

VB

Dim WC As System.Net.WebClient
Dim ipaddress As String = System.Text.Encoding.ASCII.GetString((WC.DownloadData("http://www.whatismyip.com/automation/n09230945.asp";)))

error message:
System.NullReferenceException: Object reference not set to an instance of an object.

Can anyone tell me the solution to solve this prob?

This is the Solution:

VB

Dim WC As New System.Net.WebClient
Dim ipaddress As String = System.Text.Encoding.ASCII.GetString((WC.DownloadData("http://www.whatismyip.com/automation/n09230945.asp")))
MessageBox.Show(ipaddress)

You missed the New Keyword to declare Object..
