Basic Client - Server

Beberapa hari lalu ada teman yang menulis komentar pada postingan Remote Desktop - Pengontrol Komputer Orang Lain ,dia mendapat tugas untuk membuat aplikasi Client-Server yang fungsi aplikasi tersebut adalah untuk mengontrol Sistem Registry komputer target. Untuk memenuhi pertanyaan teman tersebut serta mengupdate Blog ini maka jawabannya saya tulis dalam bentuk postingan..
Langsung saja ini screenshot dan kodenya.

 

 Langkah Pembuatan Project

1. Buat dua buah project, yaitu Project Client dan Project Server.
2. Untuk Project Client terdiri atas 3 CommandButton, 1 Text untuk menampung IP Address komputer target (server), 1 label info koneksi  dan 1 Component Microsoft Winsock Control 6.0. Lebih jelasnya lihat gambar di atas.
3. UntukProject Server cukup 1 label info dan 1 Component Microsoft Winsock Control 6.0.

Copy Paste Code dibawah ini pada form Project Client.

'panggil URL
Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long
Private Const conSwNormal = 1

Private Sub ConnectToServer()
On Error Resume Next
        WscClient.Connect Text1.Text, 2010
End Sub
Private Sub DisConnectToServer()
        WscClient.Close
End Sub
Private Sub Command1_Click()
    If Command1.Caption = "Connect" Then
        ConnectToServer
    ElseIf Command1.Caption = "Disconnect" Then
        DisConnectToServer
        Command1.Caption = "Connect"
        Command2.Enabled = False
        Command3.Enabled = False
        lblInfo.Caption = "Belum Konek Server..."
    End If
End Sub


Private Sub Command2_Click()
   WscClient.SendData "enablereg"
End Sub

Private Sub Command3_Click()
    WscClient.SendData "disablereg"
End Sub

Private Sub Form_Load()
    WscClient.Protocol = sckTCPProtocol
End Sub

Private Sub Label1_Click()
ShellExecute hwnd, "open", "Http://vbasiccode.blogspot.com", vbNullString, vbNullString, conSwNormal

End Sub

Private Sub Label2_Click()
ShellExecute hwnd, "open", "http://vbasiccode.blogspot.com/2010/04/tutorial-ptc.html", vbNullString, vbNullString, conSwNormal
End Sub

Private Sub Label3_Click()
ShellExecute hwnd, "open", "http://www.facebook.com/OutOfStack", vbNullString, vbNullString, conSwNormal

End Sub

Private Sub WscClient_Close()
        Command1.Caption = "Connect"
        Command2.Enabled = False
        Command3.Enabled = False
        lblInfo.Caption = "Aplikasi Server Ditutup..."
End Sub

Private Sub WscClient_Connect()
    lblInfo.Caption = "Terkoneksi dengan Server"
    Command2.Enabled = True
    Command3.Enabled = True
    Command1.Caption = "Disconnect"
End Sub
Private Sub WscClient_DataArrival(ByVal bytesTotal As Long)
Dim date_primite As String
Dim Vector() As String
WscClient.GetData date_primite
Vector = Split(date_primite, "|")

Select Case Vector(0)

Case "laporan"
    MsgBox Vector(1)
End Select

End Sub

Copy Paste Code dibawah ini pada form Project Server.

Private Sub Form_Load()
    WskServer.LocalPort = 2010
    WskServer.Listen
End Sub


Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)
        WskServer.Close
End Sub

Private Sub WskServer_Close()
    WskServer.Close
    WskServer.Listen
    lblInfo.Caption = "Koneksi ditutup Client..."
End Sub

Private Sub WskServer_ConnectionRequest(ByVal requestID As Long)
    WskServer.Close
    WskServer.Accept requestID
    lblInfo.Caption = "Terkoneksi dengan client..."
End Sub

Private Sub WskServer_DataArrival(ByVal bytesTotal As Long)
    Dim date_primite As String
    Dim Vector() As String
    Dim regrun
    Set regrun = CreateObject("WScript.Shell")
    WskServer.GetData date_primite
    Vector = Split(date_primite, "|")
    Select Case Vector(0)
    Case "disablereg"
        regrun.regwrite "HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System\DisableRegistryTools", 1, "REG_DWORD"
        regrun.regwrite "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System\DisableRegistryTools", 1, "REG_DWORD"
        WskServer.SendData "laporan|" + "Laporan dari Server:""Registry Server tidak dapat dibuka."""
    Case "enablereg"
        regrun.regwrite "HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System\DisableRegistryTools", 0, "REG_DWORD"
        regrun.regwrite "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System\DisableRegistryTools", 0, "REG_DWORD"
        WskServer.SendData "laporan|" + "Laporan dari Server: ""Registry Server sudah dapat dibuka kembali."""
    End Select

End Sub

Private Sub WskServer_Error(ByVal Number As Integer, Description As String, ByVal Scode As Long, ByVal Source As String, ByVal HelpFile As String, ByVal HelpContext As Long, CancelDisplay As Boolean)
    WskServer.Close
    WskServer.Listen
End Sub
