Writing to Serial Port in Windows Mobile 5.0

SerialNET.Port
--------------------------------------------------------------------------------

Can anybody tell me how to use SerialNET.Port in Visual Studio 2005.

I am currently developing a project in vb.net for Windows Mobile 5.0 Compact Framework 2.0. When I use the following syntax:-

Dim objport as New SerialNET.Port I get an error saying that SerialNET.Port is not defined.

I am using imports for System.Net, System.IO and System.IO.Ports.

Am I missing something ??

Windows Mobile or Windows CE?

And the object is called SerialPort (System.IO.Ports.SerialPort) not SerialNet.Port (at least in my version of CF2.0)

hi! i'm trying to communicate a ipaq hp hx2700 with windows mobile 5.0 with my pc via serial port.

i'm having some troubles to send data from the pc to the pda....it says the mistake is because im not using control.invoke method.

i dont know how to use it and i dont understand the visual studio 2005 help.

here's my code:

 Imports System
Imports System.IO.Ports
Imports System.Windows.Forms.Control
 
Public Class Form1
 
    Dim WithEvents control As Control = New _
     System.Windows.Forms.Control(CheckForIllegalCrossThreadCalls.False)
 
    Dim WithEvents port As SerialPort = New _
     System.IO.Ports.SerialPort("COM1", 9600, Parity.None, 8, StopBits.One)
 
    Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
 
        If port.IsOpen = False Then
            port.Open()
        End If
 
    End Sub
 
    Private Sub port_DataReceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles port.DataReceived
        TextBox1.Text = (port.ReadTo("!%"))
        If port.ReadExisting.Length = 0 Then
            ListBox1.Items.Add(TextBox1.Text)
            TextBox1.Text = ""
        End If
    End Sub
 
    Private Sub Form1_Close(ByVal sender As Object, ByVal e As _
                           System.EventArgs) Handles Me.Load
        If port.IsOpen = True Then port.Close()
    End Sub
 
    Private Sub MenuItem1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MenuItem1.Click
        Application.Exit()
    End Sub
End Class

Using Invoke usually means you are trying to avoid erros caused by interacting with a GUI component on a thread that it was not created on.
If an event handler for an object that runs with it's own thread is going to modify a GUI component you will have implement some thread-safe accessing methods.
I recomend you familarize yourself with the msdn library/help, it can be very usefull once you get the hang of using it.
