Here's how I do it:

Put this stuff in the Declarations:

'******************************
' ReBoot Function definitions:
'******************************

Private Type LUID
    UsedPart As Long
    IgnoredForNowHigh32BitPart As Long
End Type
 
Private Type TOKEN_PRIVILEGES
    PrivilegeCount As Long
    TheLuid As LUID
    Attributes As Long
End Type
 
Private Const EWX_SHUTDOWN As Long = 1
Private Const EWX_FORCE As Long = 4
Private Const EWX_REBOOT = 2
Private Const EWX_LOGOFF = 0

Private Declare Function ExitWindowsEx Lib "user32" (ByVal dwOptions As Long, ByVal dwReserved As Long) As Long
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
 

Now add these procedures:

Private Sub AdjustToken()
Const TOKEN_ADJUST_PRIVILEGES = &H20
Const TOKEN_QUERY = &H8
Const SE_PRIVILEGE_ENABLED = &H2
Dim hdlProcessHandle As Long
Dim hdlTokenHandle As Long
Dim tmpLuid As LUID
Dim tkp As TOKEN_PRIVILEGES
Dim tkpNewButIgnored As TOKEN_PRIVILEGES
Dim lBufferNeeded As Long
 
    hdlProcessHandle = GetCurrentProcess()
    OpenProcessToken hdlProcessHandle, (TOKEN_ADJUST_PRIVILEGES Or TOKEN_QUERY), hdlTokenHandle
 
    ' Get the LUID for shutdown privilege
    LookupPrivilegeValue "", "SeShutdownPrivilege", tmpLuid
 
    tkp.PrivilegeCount = 1    ' One privilege to set
    tkp.TheLuid = tmpLuid
    tkp.Attributes = SE_PRIVILEGE_ENABLED
 
    ' Enable the shutdown privilege in the access token of this process
    AdjustTokenPrivileges hdlTokenHandle, False, tkp, Len(tkpNewButIgnored), tkpNewButIgnored, lBufferNeeded
 
End Sub
 


Public Sub ExitWindows()
    AdjustToken
    ExitWindowsEx (EWX_SHUTDOWN Or EWX_FORCE), &HFFFF
End Sub

Public Sub LogOff()
    AdjustToken
    ExitWindowsEx (EWX_LOGOFF Or EWX_FORCE), &HFFFF
End Sub

Public Sub ReBoot()
    AdjustToken
    ExitWindowsEx (EWX_REBOOT Or EWX_FORCE), &HFFFF
End Sub


Now you have a choice!

I dunno...works for me!
