    Question How to prevent windows for shutdown/reboot/logoff?

    Hi, i'm in project to make i-cafe software (i use microsoft access 2003). Any one can help me how to prevent user to shutdown the computer while my application still running even in windows vista/7? I can do that in windows xp without any problem. Here my code:

    Option Explicit
    Option Compare Database
    Dim exittes As Boolean, cekexit As Boolean

    Private Sub Form_Load()
    exittes = False
    cekexit = False
    End Sub

    Private Sub Form_Timer()
    Dim WsShell
    Set WsShell = CreateObject("WScript.Shell")
    If (Kosong(txt)) And (Kosong(GetFileName(GetHwndEXE(GetForegroundWindow())))) Then
    Me.SetFocus
    WsShell.SendKeys "{ESC}"
    End If
    If cekexit = True Then
    Me.SetFocus
    WsShell.SendKeys "{ESC}"
    cekexit = False
    End If
    End Sub

    Private Sub Form_Unload(Cancel As Integer)
    cekexit = True
    If exittes = False Then
    Cancel = 1
    End If
    End Sub

    The code in Form_Timer event i use for windows vista/7 to close the screen dialog for force close open application.

    I wouldn't use a program that didn't let me control my own PC. Why prevent shutdown, if the user wants to. What happens if YOUR APP CRASHES?
