在Win2000下比较难用，你还要获得系统权限的 你须要引用下面的API 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 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 Declare Function GetCurrentProcess Lib "kernel32" () As Long Declare Function LookupPrivilegeValue Lib "advapi32.dll" Alias "LookupPrivilegeValueA" (ByVal lpSystemName As String, ByVal lpName As String, lpLuid As LUID) As Long 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 Declare Function OpenProcessToken Lib "advapi32.dll" (ByVal ProcessHandle As Long, ByVal DesiredAccess As Long, TokenHandle As Long) As Long Sub AdjustTokenPrivilegesForNT() 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 tkp.Privileges(0).pLuid = tmpLuid tkp.Privileges(0).Attributes = SE_PRIVILEGE_ENABLED AdjustTokenPrivileges hdlTokenHandle, False, tkp, _ Len(tkpNewButIgnored), tkpNewButIgnored, _ lBufferNeeded End Sub 关机时用下面的代码 AdjustTokenPrivilegesForNT ExitWindowsEx uFlags, 0 |
