[RESOLVED] Sending ping?

[Sokka93]

I'm making a roll call program with C# and I want to use my program on a computer that will sends pings every computers' IP address that that I want. I can send ping some computers but others don't work. I can't send ping every computers. Could you please help me with it?
Thank in advance.

Welcome to VBForums.
So you're saying you can ping certain computers but not all? Could you show us how you are pinging them?

Here you are

string address;
                address = textBox1.Text;
                Ping p = new Ping();
                PingReply reply = p.Send(address);
                if (reply.Status == IPStatus.Success)
                {
                    textBox2.Text = System.Net.Dns.GetHostByAddress(address).HostName.ToString();
                    MessageBox.Show("");
                }
                else
                    MessageBox.Show("Nooooooooo!");

Your code seems to work fine, apart from the second line. You're using a variable 'adres' while you've declared 'address'.

There are a lot of reasons why a ping request isn't answered.
It could be send to a router that blocks ping requests.
Firewalls (either hardware or software) can also block ping requests.
