Moin, ich hatte mir für Win98 mal son Proggie geschrieben, dass den Rechner zu einer bestimmten Uhrzeit runterfährt. Hatte dazu ExitWindowsEx benutzt. Unter Win2000 krieg ich immer die Meldung "ungültiger Eigenschaftswert" ich kriegs einfach nicht hin. Hat jemand ne Idee? Gruß hepna

In Win 2000 müssen für Dein Programm erst Berechtigungen angefordert werden um herunterfahren zu lassen, und das ist eine Sache für sich.
Allerdings sollte das ExitWindowsEx ohne Fehler funktionieren, nur geht da der Rechner maximal in Standby.

Code zum Runterfahren in 2000:
in ein Modul

Private Const EWX_LOGOFF = 0
Private Const EWX_SHUTDOWN = 1
Private Const EWX_REBOOT = 2
Private Const EWX_FORCE = 4
Private Const TOKEN_ADJUST_PRIVILEGES = &H20
Private Const TOKEN_QUERY = &H8
Private Const SE_PRIVILEGE_ENABLED = &H2
Private Const ANYSIZE_ARRAY = 1
Private Const VER_PLATFORM_WIN32_NT = 2
Type OSVERSIONINFO
dwOSVersionInfoSize As Long
dwMajorVersion As Long

End Type
Type LUID

End Type
Type LUID_AND_ATTRIBUTES
pLuid As LUID

End Type

End Type
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 Function ExitWindowsEx Lib "user32" (ByVal uFlags As Long, ByVal dwReserved As Long) As Long
Private Declare Function GetVersionEx Lib "kernel32" Alias "GetVersionExA" (ByRef lpVersionInformation As OSVERSIONINFO) As Long
Detect if the program is running under Windows NT
Public Function IsWinNT() As Boolean
Dim myOS As OSVERSIONINFO
myOS.dwOSVersionInfoSize = Len(myOS)
GetVersionEx myOS
IsWinNT = (myOS.dwPlatformId = VER_PLATFORM_WIN32_NT)
End Function
set the shut down privilege for the current application
Private Sub EnableShutDown()
Dim hProc As Long
Dim hToken As Long
Dim mLUID As LUID
Dim mPriv As TOKEN_PRIVILEGES
Dim mNewPriv 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)
End Sub
Shut Down NT
Public Sub ShutDownNT(Force As Boolean)
Dim ret As Long
Dim Flags As Long
Flags = EWX_SHUTDOWN
If Force Then Flags = Flags + EWX_FORCE
If IsWinNT Then EnableShutDown
ExitWindowsEx Flags, 0
End Sub
Restart NT
Public Sub RebootNT(Force As Boolean)
Dim ret As Long
Dim Flags As Long
Flags = EWX_REBOOT
If Force Then Flags = Flags + EWX_FORCE
If IsWinNT Then EnableShutDown
ExitWindowsEx Flags, 0
End Sub
Log off the current user
Public Sub LogOffNT(Force As Boolean)
Dim ret As Long
Dim Flags As Long
Flags = EWX_LOGOFF
If Force Then Flags = Flags + EWX_FORCE
ExitWindowsEx Flags, 0
End Sub

In eine Form mit 3 Command-Buttons

Private Sub Command1_Click()
LogOffNT True
End Sub
Private Sub Command2_Click()
RebootNT True
End Sub
Private Sub Command3_Click()
ShutDownNT True
End Sub
Private Sub Form_Load()
Command1.Caption = "Log Off NT"
Command2.Caption = "Reboot NT"
Command3.Caption = "Shutdown NT"
End Sub

Leider geht hier die formatierung etwas verloren
