apro una nuova discussione perchè in quelle che ho trovato c'è una confusione incredibile. in particolare non c'è risposta alla domanda "perchè mi compare la schermata ORA SI PUO' SPEGNERE IL COMPUTER"??

io ho provato questo codice

codice:
Option Explicit

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 As Long = 2
Private Const EWX_POWEROFF As Long = 8

Private Declare Function ExitWindowsEx Lib "User32.dll" (ByVal dwOptions As Long, ByVal dwReserved As Long) As Long

Private Declare Function GetCurrentProcess Lib "Kernel32.dll" () As Long

Private Declare Function LookupPrivilegeValue Lib "Advapi32.dll" Alias "LookupPrivilegeValueA" (ByVal lpSystemName As String, ByVal lpName As String, lpLuid As LUID) As Long
Private Declare Function AdjustTokenPrivileges Lib "Advapi32.dll" (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 Sub AdjustToken()
    Const TOKEN_ADJUST_PRIVILEGES = &H20
    Const TOKEN_QUERY = &H8
    Const SE_PRIVILEGE_ENABLED = &H2
    Dim hdlProcessHandle As Long, hdlTokenHandle As Long
    Dim tmpLuid As LUID
    Dim tkp As TOKEN_PRIVILEGES, 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

    With tkp
        tkp.PrivilegeCount = 1    ' One privilege to set
        tkp.TheLuid = tmpLuid
        tkp.Attributes = SE_PRIVILEGE_ENABLED
    End With

    'Enable the shutdown privilege in the access token of this process.
    AdjustTokenPrivileges hdlTokenHandle, False, tkp, Len(tkpNewButIgnored), tkpNewButIgnored, lBufferNeeded

End Sub
Private Sub Command1_Click()
    'Acquisisce i diritti.
    AdjustToken
    'Arresta il sistema.
    ExitWindowsEx (EWX_SHUTDOWN Or EWX_FORCE Or EWX_POWEROFF), &HFFFF
End Sub
il pc si spegna ma mi compare la schermata "ora si può spegnere il computer"

come lo evito??
