How to save Received Messages From Gsm Modem to your Mysql Database? - vb.net

Question

I am trying to save received sms from my modem to MySQL database, and I am using MySQL Workbench for my database.
Here's my functionalities:
1. Auto detect modem
2. Connect modem
3. Send Messages
4. Read Messages
5. Handles (SerialPort Data received)
Here's the Code:1. Auto Detect Modem
'Some Imports
Imports System.Management
Imports System.Threading
Imports System.Text.RegularExpressions
Imports MySql.Data.MySqlClient
Public Class Form1
Dim result() As String
Dim query As String
Dim rcvdata As String = ""
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
Dim ports() As String
ports = Split(ModemsConnected(), "***")
For i As Integer = 0 To ports.Length - 2
ComboBox1.Items.Add(ports(i))
Next
End Sub
Public Function ModemsConnected() As String
Dim modems As String = ""
Try
Dim searcher As New ManagementObjectSearcher("root\CIMV2", "SELECT * FROM Win32_POTSModem")
For Each queryObj As ManagementObject In searcher.Get()
If queryObj("Status") = "OK" Then
modems = modems & (queryObj("AttachedTo") & " - " & queryObj("Description") & "***")
End If
Next
Catch err As ManagementException
MessageBox.Show("An error occurred while querying for WMI data: " & err.Message)
Return ""
End Try
Return modems
End Function
'Show Detected or Available modem
Private Sub ComboBox1_SelectedValueChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedValueChanged
Label1.Text = Trim(Mid(ComboBox1.Text, 1, 5))
End Sub
2. Connect/Disconnect Modem
'button connect
Private Sub btnConnect_Click(sender As System.Object, e As System.EventArgs) Handles btnConnect.Click
Try
With SerialPort1
.PortName = Label1.Text
.BaudRate = 9600
.Parity = IO.Ports.Parity.None
.DataBits = 8
.StopBits = IO.Ports.StopBits.One
.Handshake = IO.Ports.Handshake.None
.RtsEnable = True
.ReceivedBytesThreshold = 1
.NewLine = vbCr
.ReadTimeout = 1000
.Open()
End With
If SerialPort1.IsOpen Then
Label3.Visible = True
btnDisconnect.Visible = True
Label3.Text = "Connected - Port " & Label1.Text & " is used"
Else
Label3.Text = "Got some Error, Check your connection with your Modem."
End If
Catch ex As Exception
MsgBox(ex.Message, MsgBoxStyle.Exclamation, "Text Messaging")
End Try
End Sub
'button Disconnect
Private Sub btnDisconnect_Click(sender As System.Object, e As System.EventArgs) Handles btnDisconnect.Click
Try
If SerialPort1.IsOpen Then
With SerialPort1
.Close()
.Dispose()
Label1.Visible = False
Label3.Visible = False
btnDisconnect.Visible = False
ListView1.Items.Clear()
End With
End If
Catch ex As Exception
MsgBox(ex.Message)
End Try
End Sub
3. Send Messages
Private Sub btnSend_Click(sender As System.Object, e As System.EventArgs) Handles btnSend.Click
Dim query As String
Try
Connection()
query = "INSERT INTO thesis.tblsentitems (PhoneNumber, message) VALUES('" & txtNumber.Text & "', '" & txtMessage.Text & "')"
sqlcmd = New MySqlCommand(query, conn)
sqlreader = sqlcmd.ExecuteReader
With SerialPort1
.Write("at" & vbCrLf)
Threading.Thread.Sleep(200)
.Write("at+cmgf=1" & vbCrLf)
Threading.Thread.Sleep(200)
.Write("at+cmgs=" & Chr(34) & txtNumber.Text & Chr(34) & vbCrLf)
.Write(txtMessage.Text & Chr(26))
Threading.Thread.Sleep(200)
End With
If rcvdata.ToString.Contains(">") Then
MsgBox("Message Succesfully Sent")
conn.Close()
Else
MsgBox("Got some error!")
End If
Catch ex As Exception
MsgBox(ex.Message, MsgBoxStyle.Exclamation, "Text Messaging")
End Try
End Sub
4. Read Messages
Private Sub btnReadsms_Click(sender As System.Object, e As System.EventArgs) Handles btnReadsms.Click
Try
With SerialPort1
.Write("AT" & vbCrLf)
Threading.Thread.Sleep(1000)
.Write("AT+CMGF=1" & vbCrLf)
Threading.Thread.Sleep(1000)
.Write("AT+CPMS=""SM""" & vbCrLf)
Threading.Thread.Sleep(1000)
.Write("AT+CMGL=""ALL""" & vbCrLf)
Threading.Thread.Sleep(1000)
'MsgBox(rcvdata.ToString)
readmsg()
End With
Catch ex As Exception
MsgBox(ex.Message)
End Try
End Sub
'Save Received message to ListView1
Private Sub readmsg()
Try
Dim lineoftext As String
Dim i As Integer
Dim arytextfile() As String
lineoftext = rcvdata.ToString
arytextfile = Split(lineoftext, "+CMGL", , CompareMethod.Text)
For i = 1 To UBound(arytextfile)
Dim input As String = arytextfile(i)
Dim pattern As String = "(:)|(,"")|("","")"
result = Regex.Split(input, pattern)
Dim concat() As String
With ListView1.Items.Add("null")
'for index
.SubItems.AddRange(New String() {result(2).ToString})
'for status
.SubItems.AddRange(New String() {result(4).ToString})
'for number
Dim my_string, position As String
my_string = result(6)
position = my_string.Length - 2
my_string = my_string.Remove(position, 2)
.SubItems.Add(my_string)
'for date and time
concat = New String() {result(8)}
.SubItems.AddRange(concat)
'for message
Dim lineoftexts As String
Dim arytextfiles() As String
lineoftexts = arytextfile(i)
arytextfiles = Split(lineoftexts, "+32", , CompareMethod.Text)
.SubItems.Add(arytextfiles(1))
End With
Next
Catch ex As Exception
MsgBox(ex.Message)
End Try
End Sub
5. Handles (SerialPort Data received)
Private Sub SerialPort1_datareceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort1.DataReceived
Dim datain As String = ""
Dim numbytes As Integer = SerialPort1.BytesToRead
For i As Integer = 1 To numbytes
datain &= Chr(SerialPort1.ReadChar)
Next
test(datain)
End Sub
Private Sub test(ByVal indata As String)
rcvdata &= indata
End Sub
Hope someone can Help, please... :/
