Coloque os comandos abaixo em um módulo:

Private Const EWX_LOGOFF = 0
Private Const EWX_SHUTDOWN = 1
Private Const EWX_REBOOT = 2
Private Const EWX_FORCE = 4
Private Const EWX_POWEROFF = &H8

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

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" (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
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
AdjustTokenPrivileges hToken, False, mPriv, 4 + (12 * mPriv.PrivilegeCount), mNewPriv, 4 + (12 * mNewPriv.PrivilegeCount)
End Sub
Public Sub ShutDown2000(Force As Boolean)
Dim ret As Long
Dim Flags As Long
Flags = EWX_POWEROFF
If Force Then Flags = Flags + EWX_FORCE
If IsWinNT Then EnableShutDown
ExitWindowsEx Flags, 0
End Sub
Public Sub Reboot2000(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
Public Sub LogOff2000(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

Depois é só utilizar em algum controle do seu form (Button, etc) as seguintes chamadas:


LogOff2000 False 'Para Logoff, ou

Reboot2000 False 'Para Reboot, ou

ShutDown2000 False' 'Para Shutdown

Obs.: O false depois da chamada é para fazer o Logoff/Reboot/Shutdown controlados (fechar os programas). Caso voce queira desligar "na paulada", mude para True (não recomendo)

Funciona para todos os sistemas (98, Me, NT, 2000 e XP)
