Download video klip jar of heart christina perri. First off, I just want to say thank you to the VB community. I really want to get into coding as my main stay. The fact that you guys are here to help willingly says alot about how great the community really is. Much appreciated. This is my first post, with many more to come.

Over time, I hope to be one of the guys replying to the new kid on the block with the questions. 'If you have done well in whatever business you are in, it is your duty to send the elevator back down and try to help bring up the next generation of undiscovered talent.' -Kevin Spacey With that being said, this is what I am trying to accomplish. I have a handful of servers that like to drop off of our DNS server on a daily basis.

What I am trying to do is make an application that will read in our server names and their IPs from a text file named servers.txt. So, two columns in my ListView1. I have that part working perfectly with a delimiter to separate each column. Servers.txt contents: SERVERNAME1=192.168.1.1 SERVERNAME2=192.168.1.2 SERVERNAME3=192.168.1.3 etc.

What I've done for now to visualize things is I've created 3 ListViews: Listview1 reads in the servers.txt file, Listview 2 displays successes, and Listview 3 displays failures. After that completes, I have a button to export the contents of Listview3 to a CSV file where I will run a PowerShell command against it to add the servers back to DNS. Borrowing the code from: works, but when I try to add my servers from ListView1 I get an error of 'System.ArgumentNullException: Value cannot be null.' The strange thing is that it splits the servers between Listview2 and Listview3. Showing me what I need to know.

I just want to get the error corrected if possible. Also, the app is only adding my server name to ListView 2 and 3.

I really need both Server Name and IP to copy over. I haven't figured that part out yet. Any help would be much appreciated. Here's the complete code: Imports System.Net.NetworkInformation Imports System.IO Public Class Form1 Public mPingAddresses Private Sub Form1_Load(sender As Object, e As EventArgs) Handles Me.Load ListView1.View = View.Details ListView1.Columns.Add('Server', 150) ListView1.Columns.Add('IP', 130) ListView2.View = View.Details ListView2.Columns.Add('Server', 150) ListView2.Columns.Add('IP', 130) ListView3.View = View.Details ListView3.Columns.Add('Server', 150) ListView3.Columns.Add('IP', 130) Try mPingAddresses = New List(Of String) 'Initialise the list of addresses. 'mPingAddresses.Add('192.168.1.1') 'mPingAddresses.Add('192.168.1.2') 'mPingAddresses.Add('192.168.1.3') 'mPingAddresses.Add('192.168.1.4') 'mPingAddresses.Add('192.168.1.5') Catch ex As Exception MsgBox('Error in loading the servers into the List view. First off, I just want to say thank you to the VB community.
