Hello,
How can I show the Microsoft Shut Down dialog box on a NT4 SP6
with VB 6 ?
I tryed it with this (see code)
But it only show the logon screen. When using
EWX_LogOff, EWX_SHUTDOWN, EWX_REBOOT, EWX_POWEROFF
in ExitWindowsEx, it retreives 0
Code:
--------
Public glngWhichWindows32 As Long
Private Const EWX_LogOff As Long = 0
Private Const EWX_SHUTDOWN As Long = 1
Private Const EWX_REBOOT As Long = 2
Private Const EWX_FORCE As Long = 4
Private Const EWX_POWEROFF As Long = 8
Private Const mlngWindows95 = 0
Private Const mlngWindowsNT = 1
Private Declare Function ExitWindowsEx Lib "user32" (ByVal dwOptions As Long, ByVal dwReserved As Long) As Long
Private Declare Function GetLastError Lib "kernel32" () As Long
Private Declare Function GetVersion Lib "kernel32" () 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
Private Declare Sub SetLastError Lib "kernel32" (ByVal dwErrCode As Long)
Private Type LUID
UsedPart As Long
IgnoredForNowHigh32BitPart As Long
End Type
Private Type LUID_AND_ATTRIBUTES
TheLuid As LUID
Attributes As Long
End Type
Private Type TOKEN_PRIVILEGES
PrivilegeCount As Long
TheLuid As LUID
Attributes As Long
End Type
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
SetLastError 0
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
Public Sub Shutdown()
If glngWhichWindows32 = mlngWindowsNT Then
AdjustToken
End If
ExitWindowsEx EWX_FORCE, &HFFFF
End Sub
Thanks
