I am getting .Net Framework Unhandled exception popup message when I run this program or click on tabs. It complains about "Object reference not set to an instance of an object". The first line of the details says it occured at "FormMain.ExtractStringArray(ManagementObject mo."

Hi!

I think I saw the same problem. I am running a lot of different virtual network adapters and ran into the same problem. I made some changes to the program (added a null checker.)

private void ExtractStringArray(ManagementObject mo, string prop, string name, bool first)
        {
            string[] dnsOrder = (string[])mo[prop];
            TextBoxIPs.AppendText(name + ": ");
            if (!first) TextBoxIPs.AppendText("\r\n");
            if (dnsOrder != null)
            {
                foreach (var at in dnsOrder)
                {
                    TextBoxIPs.AppendText(at + "\r\n");
                    if (first) break;
                }
            }
        }

Thanks to TomasN :-)
