[VB.NET] โค้ดโปรแกรมการเชื่อมต่อกับ MikroTik และการสั่งรัน Command

thongkorn · โพสต์ 2020-1-13 12:55:49

ปฐมบทชุดแรกที่แอดมินก็พึ่งได้เคยทำการเขียนโค้ดโปรแกรมด้วย VB.NET เพื่อทำการเชื่อมต่อเข้ากับ MikroTik และทำการรันทดสอบคอมมานด์ เพื่อดูคุณสมบัติต่างๆภายในตัว MikroTik

มาดูโค้ดกันเถอะ ...

Public Class frmConnectMikroTik
Private Sub frmConnectMikroTik_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
txtIPAddress.Text = "IP ADDRESS"
txtPort.Text = "8728"
txtUsername.Text = "admin"
txtPassword.Text = "PASSWORD"
Call OnOff(False)
End Sub
Sub OnOff(ByVal blnState As Boolean)
If blnState Then
GroupBox1.Text = " Connect to MikroTik ... "
txtIPAddress.Enabled = False
txtPort.Enabled = False
txtUsername.Enabled = False
txtPassword.Enabled = False
btnConnect.Enabled = False
btnClear.Enabled = True
btnSend.Enabled = True
txtCmd.Enabled = True
Else
GroupBox1.Text = " Log in "
txtIPAddress.Enabled = True
txtPort.Enabled = True
txtUsername.Enabled = True
txtPassword.Enabled = True
btnConnect.Enabled = True
btnClear.Enabled = False
btnSend.Enabled = False
txtCmd.Enabled = False
End If
End Sub
Function LoginMikrotik(ByVal IP As String, ByVal UN As String, ByVal PW As String) As Boolean
Dim IPAddress As System.Net.IPAddress = System.Net.IPAddress.Parse(IP)
Dim mk = New Mikrotik(IPAddress, 8728)
If Not mk.Login(Trim(txtUsername.Text), Trim(txtPassword.Text)) Then
Return False
Else
Return True
End If
End Function
Private Sub btnConnect_Click(sender As System.Object, e As System.EventArgs) Handles btnConnect.Click
If Not LoginMikrotik(txtIPAddress.Text.Trim, (txtUsername.Text), Trim(txtPassword.Text)) Then
OnOff(False)
MessageBox.Show("Sorry !!! You can't log in.", "Report Status", MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
Return
Else
'MessageBox.Show("Welcome to Mikrotik system.", "Report Status", MessageBoxButtons.OK, MessageBoxIcon.Information)
OnOff(True)
txtCmd.Focus()
'// SAMPLE
' /interface/print
'/ip/arp/print
'/system/resource/getall
txtCmd.Text = "/system/resource/print"
End If
End Sub
Private Sub txtData_KeyPress(sender As Object, e As System.Windows.Forms.KeyPressEventArgs) Handles txtResult.KeyPress
e.Handled = True
End Sub
Private Sub btnSend_Click(sender As System.Object, e As System.EventArgs) Handles btnSend.Click
If txtCmd.Text.Trim.Length = 0 Then Return
'//
Dim IPAddress As System.Net.IPAddress = System.Net.IPAddress.Parse(Trim(txtIPAddress.Text))
Dim mk = New Mikrotik(IPAddress, 8728)
Try
If mk.Login(Trim(txtUsername.Text), Trim(txtPassword.Text)) Then
txtResult.Clear()
mk.Send(Trim(txtCmd.Text), True)
Dim strLog As String = String.Empty
For Each row In mk.Read
strLog = strLog & row & vbCrLf
Next
txtResult.Text = strLog
End If
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
End Sub
Private Sub btnClear_Click(sender As System.Object, e As System.EventArgs) Handles btnClear.Click
OnOff(False)
txtResult.Clear()
End Sub
End Class
