Devi impostare i privilegi di shutdown con:
codice:
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
LookupPrivilegeValue "", "SeShutdownPrivilege", tmpLuid
tkp.PrivilegeCount = 1 ' One privilege to set
tkp.TheLuid = tmpLuid
tkp.Attributes = SE_PRIVILEGE_ENABLED
AdjustTokenPrivileges hdlTokenHandle, False, tkp, Len(tkpNewButIgnored), tkpNewButIgnored, lBufferNeeded
End Sub
Le chiamate dunque sono:
codice:
AdjustToken
ExitWindowsEx EWX_FORCE Or EWX_POWEROFF, 0&
Ricordati di inserire queste dichiarazioni:
codice:
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
