Server
Private Sub Form_Load()
Winsock1.LocalPort = 15778
Winsock2.LocalPort = 15779
Winsock1.Listen
Winsock2.Listen
End Sub

Private Sub Winsock1_ConnectionRequest(ByVal requestID As Long)
Winsock1.Accept requestID
End Sub
Private Sub Winsock2_ConnectionRequest(ByVal requestID As Long)
Winsock2.Accept requestID
End Sub

Private Sub Winsock2_DataArrival(ByVal bytesTotal As Long)
Dim data As String
Winsock2.GetData data
Label1.Caption = data
End Sub
Private Sub Winsock1_DataArrival(ByVal bytesTotal As Long)
Dim data As String
Winsock1.GetData data
Label2.Caption = data
End Sub

Client

Private Sub Form_Load()
Dim data As String
data = "testowe dane"
Winsock1.Connect
