    Shutdown Comp in XP

    sorry if this has been posted before but iahve some
    code that use to work where it check the time etc then
    when the timer fired it either shutdown reboot logoff
    depending wich option you picked

    This is the code for the EWX function in a module
    Code:
    Private Const EWX_LOGOFF = 0
    Private Const EWX_SHUTDOWN = 1
    Private Const EWX_REBOOT = 2
    Private Const EWX_FORCE = 4
    Private Const TOKEN_ADJUST_PRIVILEGES = &H20
    Private Const TOKEN_QUERY = &H8
    Private Const SE_PRIVILEGE_ENABLED = &H2
    Private Const ANYSIZE_ARRAY = 1
    Private Const VER_PLATFORM_WIN32_NT = 2
    Type OSVERSIONINFO
        dwOSVersionInfoSize As Long
        dwMajorVersion As Long
        dwMinorVersion As Long
        dwBuildNumber As Long
        dwPlatformId As Long
        szCSDVersion As String * 128
    End Type
    Type LUID
        LowPart As Long
        HighPart As Long
    End Type
    Type LUID_AND_ATTRIBUTES
        pLuid As LUID
        Attributes As Long
    End Type
    Type TOKEN_PRIVILEGES
        PrivilegeCount As Long
        Privileges(ANYSIZE_ARRAY) As LUID_AND_ATTRIBUTES
    End Type
    Private Declare Function GetCurrentProcess Lib "kernel32" () As Long
    Private Declare Function OpenProcessToken Lib "advapi32" (ByVal ProcessHandle As Long, ByVal DesiredAccess As Long, TokenHandle As Long) As Long
    Private Declare Function LookupPrivilegeValue Lib "advapi32" Alias "LookupPrivilegeValueA" (ByVal lpSystemName As String, ByVal lpName As String, lpLuid As LUID) As Long
    Private Declare Function AdjustTokenPrivileges Lib "advapi32" (ByVal TokenHandle As Long, ByVal DisableAllPrivileges As Long, NewState As TOKEN_PRIVILEGES, ByVal BufferLength As Long, PreviousState As TOKEN_PRIVILEGES, ReturnLength As Long) As Long
    Private Declare Function ExitWindowsEx Lib "user32" (ByVal uFlags As Long, ByVal dwReserved As Long) As Long
    Private Declare Function GetVersionEx Lib "kernel32" Alias "GetVersionExA" (ByRef lpVersionInformation As OSVERSIONINFO) As Long
    'Detect if the program is running under Windows NT
    Public Function IsWinNT() As Boolean
        Dim myOS As OSVERSIONINFO
        myOS.dwOSVersionInfoSize = Len(myOS)
        GetVersionEx myOS
        IsWinNT = (myOS.dwPlatformId = VER_PLATFORM_WIN32_NT)
    End Function
    'set the shut down privilege for the current application
    Private Sub EnableShutDown()
        Dim hProc As Long
        Dim hToken As Long
        Dim mLUID As LUID
        Dim mPriv As TOKEN_PRIVILEGES
        Dim mNewPriv As TOKEN_PRIVILEGES
        hProc = GetCurrentProcess()
        OpenProcessToken hProc, TOKEN_ADJUST_PRIVILEGES + TOKEN_QUERY, hToken
        LookupPrivilegeValue "", "SeShutdownPrivilege", mLUID
        mPriv.PrivilegeCount = 1
        mPriv.Privileges(0).Attributes = SE_PRIVILEGE_ENABLED
        mPriv.Privileges(0).pLuid = mLUID
        ' enable shutdown privilege for the current application
        AdjustTokenPrivileges hToken, False, mPriv, 4 + (12 * mPriv.PrivilegeCount), mNewPriv, 4 + (12 * mNewPriv.PrivilegeCount)
    End Sub
    ' Shut Down NT
    Public Sub ShutDownNT(Force As Boolean)
        Dim ret As Long
        Dim Flags As Long
        Flags = EWX_SHUTDOWN
        If Force Then Flags = Flags + EWX_FORCE
        If IsWinNT Then EnableShutDown
        ExitWindowsEx Flags, 0
    End Sub
    'Restart NT
    Public Sub RebootNT(Force As Boolean)
        Dim ret As Long
        Dim Flags As Long
        Flags = EWX_REBOOT
        If Force Then Flags = Flags + EWX_FORCE
        If IsWinNT Then EnableShutDown
        ExitWindowsEx Flags, 0
    End Sub
    'Log off the current user
    Public Sub LogOffNT(Force As Boolean)
        Dim ret As Long
        Dim Flags As Long
        Flags = EWX_LOGOFF
        If Force Then Flags = Flags + EWX_FORCE
        ExitWindowsEx Flags, 0
    End Sub
    and tis is the code that checks the time n date,
    this bit has stoped working i think as the timer
    does not seam to fire even though the start
    button enables it it doesent work
    Code:
    Private Sub Timer1_Timer()
        p = InStr(txttime, ":")
        hrs = Left$(txttime, p - 1)
        mins = Mid$(txttime, p + 1)
        mins = hrs * 60 + mins
        nowmins = Val(Mid$(Now, 10, 2)) * 60 + Val(Mid$(Now, 13, 2))
        If txtdate = Left$(Now, Len(Now) - 9) Or Check1.Value = 1 Then
            If nowmins >= mins Then
    Select Case TurnOff
        Case Is = 1
            'MsgBox "The Comp has rebooted windows"
                'Unload Form1
               ' Call ExitWindowsEx(EWX_REBOOT, 2)
               RebootNT True
        Case Is = 2
            'MsgBox "The Comp has shutdown windows"
              ' Unload Form1
             '  Call ExitWindowsEx(EWX_SHUTDOWN, 1)
             ShutDownNT True
        Case Is = 3
            'MsgBox "The Comp has logged you off"
                'Unload Form1
                'Call ExitWindowsEx(EWX_LOGOFF, 0)
                LogOffNT True
    End Select
            End If
        End If
    End Sub

    ok, Shell "Shutdown.exe -s",vbMaximizeFocus -r works great, but how you can doit with a coment?
    i know with shutdown -r -t 30 -c "good night"
    it will wait for 30 secs and will display good night.
    im using visual basic 5 and windows xp.
    i tryed:
    Shell "Shutdown.exe -r -t 79 -c powered", vbMaximizeFocus and works fine, but if i try :
    Shell "Shutdown.exe -r -t 79 -c powered by me", vbMaximizeFocus
    it doesnt works!
    any idea?¿
