Winsock Control in VB6

Code Sample:

 tcpClient.RemotePort = 110

 tcpClient.Protocol = sckTCPProtocol

 tcpClient.RemoteHost = txtPop.Text  <-- can be an IP address

 tcpClient.Connect

 tcpClient.GetData strStream

 txtOut.Text = txtOut.Text & strStream

 If tcpClient.State = 7 Then

 Sub tcpClient_DataArrival(ByVal bytesTotal As Long)
     Dim strData As String, strText As String
     tcpClient.GetData strData: Debug.Print "->" & strData
 End Sub

 Dim strOut As String
 strOut = tcpClient.State
