Mengunci Windows

Untuk Membuat program pengunci windows, tidaklah perlu susah, Pada kesempatan ini saya
mencoba memberikan contoh program tersebut.

Di Sini saya menggunakan VB 6.
Yang di perlukan adalah :

1 buah form
2 buah label
1 text
2 timer


ketikan/copas kode di bawah ini ;


-------------code---------------------------

Option Explicit
Private Declare Function SetCursorPos Lib "user32" (ByVal X As Long, ByVal Y As Long) As Long
Dim hPos As Long
Dim ShowObj As Boolean
Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
ShowObj = True
hPos = 0
End Sub
Private Sub Form_Load()
On Error Resume Next
EnumWindows AddressOf MinimizeAllWindows, ByVal 0&
SetCursorPos Text2.Left + 150, Text2.Top + 11
Me.Hide
ShowObj = True
tunggu 1
PrintScreen Me
tunggu 1
Me.Show

Timer1.Enabled = True
Timer2.Enabled = True
End Sub
Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
'If Button <> 0 Then
ShowObj = True
hPos = 0
'End If
End Sub
Private Sub Text2_KeyPress(KeyAscii As Integer)
On Error Resume Next
If KeyAscii = 13 Then
If (Text2.Text = GlobalAdminPwd) Then
Timer1.Enabled = False
Timer2.Enabled = False
LetShowWindow
Unload Me
MsgBox "Windows Berhasil Di Buka", 64
Else
Text2.Text = ""
End If
KeyAscii = 0
End If
End Sub

Private Sub Timer1_Timer()
LetHideWindow Me.HWND
BringWindowToTop Me.HWND
End Sub
Private Sub Timer2_Timer()
On Error Resume Next
If ShowObj Then
If Text2.Visible = False Then
Text2.Visible = True
Shape1.Visible = True
Shape2.Visible = True
Label1.Visible = True
Label2.Visible = True
Image1.Visible = True
SetCursorPos Text2.Left + 150, Text2.Top + 10
End If
Else
If Text2.Visible = True Then
Text2.Visible = False
Shape1.Visible = False
Shape2.Visible = False
Label1.Visible = False
Label2.Visible = False
Image1.Visible = False
End If

End If
If hPos < 10 Then
hPos = hPos + 1
Else
ShowObj = False
End If
End Sub
Sub tunggu(miliSecond As Single)
Dim pos As Single
Dim H
pos = 0.00001
H = miliSecond
While pos < H
DoEvents
If pos < H Then
pos = pos + 0.00001
End If
Wend
End Sub


dan untuk Modulenya adalah :
