ما هو كود اغلاق ويندوز XP من الفيجوال بيسك

this code in module and then just call the shutdown function from the form

اشكرك يا اخ احمد على اهتمامك و لكن هذا الكود لم يعمل و عند الضغط على الزر Run تظهر رسالة خطأ مكتوب فيها User-defined type not defined

ارجو ان تتاكد من صحة الكود

و شكرا......

جرب هذا :

'IN THE FORM
Public Function ShutDownSystem(Force As Boolean) As String
   On Error GoTo Failed
   Dim Flags As Long
   Flags = EWX_SHUTDOWN
   If Force Then Flags = Flags + EWX_FORCE
   If IsWinNT Then
       If EnableShutDown = True Then
           If ExitWindowsEx(Flags, 0) <> 0 Then
               ShutDownNT = "T"
           End If
       End If
   Else
       If ExitWindowsEx(EWX_FORCE Or EWX_SHUTDOWN, 0) <> 0 Then
               ShutDownNT = "T"
       End If
   End If
   Exit Function
Failed:
   ShutDownNT = "F" & Err.Description
End Function
Private Function EnableShutDown() As String
'Set the shut down privilege for the current application
On Error GoTo Failed
   Dim hProc As Long
   Dim hToken As Long
   Dim mLUID As LUID
   Dim mPriv 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)
   EnableShutDown = True
   Exit Function
Failed:
   EnableShutDown = False
End Function
Private Function IsWinNT() As Boolean
   If OSversion = WINNT_XP_SERVER Then
       IsWinNT = True
   End If
End Function

وهذا فى Module

Public Declare Function GetCurrentProcess Lib "kernel32" () As Long
Public Declare Function OpenProcessToken Lib "advapi32" (ByVal ProcessHandle As Long, ByVal DesiredAccess As Long, TokenHandle As Long) As Long
Public Declare Function LookupPrivilegeValue Lib "advapi32" Alias "LookupPrivilegeValueA" (ByVal lpSystemName As String, ByVal lpName As String, lpLuid As LUID) As Long
Public 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
Public Declare Function ExitWindowsEx Lib "user32" (ByVal uFlags As Long, ByVal dwReserved As Long) As Long



Public Const EWX_LOGOFF = 0
Public Const EWX_SHUTDOWN = 1
Public Const EWX_REBOOT = 2
Public Const EWX_FORCE = 4
Public Const TOKEN_ADJUST_PRIVILEGES = &H20
Public Const TOKEN_QUERY = &H8
Public Const SE_PRIVILEGE_ENABLED = &H2
Public Const ANYSIZE_ARRAY = 1
Public Const VER_PLATFORM_WIN32_NT = 2
Public Const WM_DRAWCLIPBOARD = &H308
Public Const GWL_WNDPROC = (-4)
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

سيعمل هذا إن شاء الله
