Ping VB.net List Box

Good Morning,

I'm trying to figure something out. I have this code below that will ping a system in my listbox (If its selected) . if the ping is successful then it will send me an email.

What I'm trying to do is loop through ALL the systems in the list box "continuously". Can someone please help me with this?

        Try

            If My.Computer.Network.Ping(Systems.SelectedItem) Then
          
                Try
                    Dim Smtp_Server As New SmtpClient
                    Dim e_mail As New MailMessage()
                    Smtp_Server.UseDefaultCredentials = False
                    Smtp_Server.Credentials = New Net.NetworkCredential("user@gmail.com", "Password")
                    Smtp_Server.Port = 587
                    Smtp_Server.EnableSsl = True
                    Smtp_Server.Host = "smtp.gmail.com"

                    e_mail = New MailMessage()
                    e_mail.From = New MailAddress("name@gmail.com")
                    e_mail.To.Add("name@ccp.edu")
                    e_mail.Subject = "System Status"
                    e_mail.IsBodyHtml = False
                    e_mail.Body = "The system is Online"
                    Smtp_Server.Send(e_mail)
                    MsgBox("Mail Sent")

                Catch error_t As Exception
                    MsgBox(error_t.ToString)
                End Try
            Else

            End If
        Catch ex As Exception

        End Try

you need to get the count from the list box and then loop on that.
So outside the ping do a
DO ... UNTIL this gives you the option to stop it.
inside the DO ... UNTIL use a FOR ... EACH to select each listbox item.
then inside the FOR ... EACH insert your ping & email code.
Put the ping code inside a background worker thread otherwise it'll seem like it's locked up.
