Dim hhkLowLevelKybd As Long
Private Sub chkDisable_Click()
If chkDisable = vbChecked Then
      hhkLowLevelKybd = SetWindowsHookEx(WH_KEYBOARD_LL, AddressOf LowLevelKeyboardProc, App.hInstance, 0)
Else
      UnhookWindowsHookEx hhkLowLevelKybd
      hhkLowLevelKybd = 0
End If
End Sub
Private Sub Form_Unload(Cancel As Integer)
If hhkLowLevelKybd <> 0 Then UnhookWindowsHookEx hhkLowLevelKybd
End Sub
in new module named modDisableLowLevelKeys.bas
