Hi Guys,

I have done so many research the whole week and tried all different codes from google, yahoo. code projects. etc.

So far i have tried major links below:

Sending SMS using .NET[^]


My Actual Code is here:

For SMSCOMMS Class

Imports System
Imports System.Threading
Imports System.ComponentModel
Imports System.IO.Ports

Public Class SMSCOMMS
    Private WithEvents SMSPort As SerialPort

    Private SMSThread As Thread
    Private ReadThread As Thread
    Shared _Continue As Boolean = False
    Shared _ContSMS As Boolean = False
    Private _Wait As Boolean = False
    Shared _ReadPort As Boolean = False
    Public Event Sending(ByVal Done As Boolean)
    Public Event DataReceived(ByVal Message As String)

    Public Sub New(ByRef COMMPORT As String)
        SMSPort = New SerialPort
        With SMSPort
            .PortName = COMMPORT
            .BaudRate = 9600
            .Parity = Parity.None
            .DataBits = 8
            .StopBits = StopBits.One
            .Handshake = Handshake.RequestToSend
            .DtrEnable = True
            .RtsEnable = True
            .NewLine = vbCrLf
        End With
        ReadThread = New Thread(AddressOf ReadPort)
    End Sub

    Public Function SendSMS(ByVal CellNumber As String,ByVal SMSMessage As String) As Boolean
        Dim MyMessage As String = Nothing
        'Check if Message Length <= 160
        If SMSMessage.Length <= 160 Then
            MyMessage = SMSMessage
        Else
            MyMessage = Mid(SMSMessage, 1, 160)
        End If
        If IsOpen = True Then
            SMSPort.WriteLine("AT+CMGS=" & CellNumber & vbCr)
            _ContSMS = False
            SMSPort.WriteLine(MyMessage & vbCrLf & Chr(26))
            _Continue = False
            RaiseEvent Sending(False)
        End If
    End Function

    Private Sub ReadPort()
        Dim SerialIn As String = Nothing
        Dim RXBuffer(SMSPort.ReadBufferSize) As Byte
        Dim SMSMessage As String = Nothing
        Dim Strpos As Integer = 0
        Dim TmpStr As String = Nothing

        While SMSPort.IsOpen = True
            If (SMSPort.BytesToRead <> 0) And (SMSPort.IsOpen = True) Then
                While SMSPort.BytesToRead <> 0
                    SMSPort.Read(RXBuffer, 0, SMSPort.ReadBufferSize)
                    SerialIn = SerialIn & System.Text.Encoding.ASCII.GetString(RXBuffer)
                    If SerialIn.Contains(">") = True Then
                        _ContSMS = True
                    End If
                    If SerialIn.Contains("+CMGS:") = True Then
                        _Continue = True
                        RaiseEvent Sending(True)
                        _Wait = False
                        SerialIn = String.Empty
                        ReDim RXBuffer(SMSPort.ReadBufferSize)
                    End If
                End While
                RaiseEvent DataReceived(SerialIn)
                SerialIn = String.Empty
                ReDim RXBuffer(SMSPort.ReadBufferSize)
            End If
        End While
    End Sub

    Public ReadOnly Property IsOpen() As Boolean
        Get
            If SMSPort.IsOpen = True Then
                IsOpen = True
            Else
                IsOpen = False
            End If
        End Get
    End Property

    Public Sub Open()
        If IsOpen = False Then
            SMSPort.Open()
            ReadThread.Start()
        End If
    End Sub

    Public Sub Close()
        If IsOpen = True Then
            SMSPort.Close()
        End If
    End Sub
End Class

For Form1

Option Explicit On
Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim SMSEngine As SMSCOMMS
        SMSEngine = New SMSCOMMS("COM5")
        SMSEngine.Open()
        SMSEngine.SendSMS("9234996080", "SMS Testing")
        SMSEngine.Close()
    End Sub
End Class

Still do not work at all. i am sure that Comp port number is 5 since i tried downloading SMS cast from smscaster.com and tried their trial API.

Also i have tried this

[^]

but this one is more complicated than i have imagine and it has a cost for license.
