  • yes, it is also possible in free version
  • I have tried to create a little vb.net script that send tcp/ip command but that don't run !
    This is my code:
    Imports System.Net.Sockets
    Imports System.Net
    Imports System.Text

    Public Class Form1
        Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
            sendtonavigator()
        End Sub

        Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
            WriteData("$destination=45.72813,8.98105;navigate\n", "127.0.0.1")
        End Sub

        ''' <summary>
        ''' Send data over TCP/IP network
        ''' </summary>
        ''' <param name="data">Data string to write</param>
        ''' <param name="IP">The connected destination TcpClient</param>
        Public Sub WriteData(ByVal data As String, ByRef IP As String)
            'Console.WriteLine("Sending message """ & data & """ to " & IP)
            Dim client As TcpClient = New TcpClient()
            client.Connect(New IPEndPoint(IPAddress.Parse(IP), "4242"))
            Dim stream As NetworkStream = client.GetStream()
            Dim sendBytes As Byte() = Encoding.ASCII.GetBytes(data)
            stream.Write(sendBytes, 0, sendBytes.Length)
        End Sub

        Public Sub sendtonavigator()
            Dim host As IPAddress = Nothing
            Dim mySock As Socket = Nothing
            Try
                If Not IPAddress.TryParse("127.0.0.1", host) Then
                    MessageBox.Show("Adresse non valide")
                    Exit Sub
                End If
                Dim ep As IPEndPoint = New IPEndPoint(host, Integer.Parse(4242))
                mySock = New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)
                mySock.Connect(ep)
                If mySock.Connected Then
                    mySock.Send(Encoding.ASCII.GetBytes("$destination=45.72813,8.98105;navigate\n"))
                    'mySock.Send(Encoding.ASCII.GetBytes("$message=""message"";ask;instant\n"))
                End If
            Catch ex As Exception
                MessageBox.Show(ex.Message)
            End Try
        End Sub

    End Class
    As you can see, i have tried two differents commands that don't run !
    Thanks for your help !
  • Is your Navigator configured to accept remote commands? (settings/Remote communication device)
    The simplest test is via telnet console.
  • Yes , my settings are :
    127.0.0.1
    4242
  • I am not used to Basic, but ... can you keep the connection open? Navigator accepts only one connection. Also can you wait for Navigator response? It is possible that you terminate the connection even before Navigator reads the buffers.
  • Hoops,
    I don't know !
  • I have found a Python example on this link that i try without success (i don't know python)!
    http://forum.mapfactor.com/discussion/38#Item_7

    The run option return me:
    Traceback (most recent call last):
      File "C:\tmp\VB.NET-2010\VB.NET Pc_Navigator_TCP-IP interface\python.py", line 5, in <module>
        telnet = Telnet( IP, PORT )
    NameError: name 'Telnet' is not defined
  • Ok, i worked a little beat on my issues and found to solutions, an autoit script (thanks to the french forum) and a VB.Net module.
