权限获得问题

[haley_hj]

请问在NT/XP/2K下如何使应用程序拥有SE_SHUTDOWN_NAME Privilege(关机权限)﹐因为在NT/2K/XP下﹐仅使用ExitWindowsEx()无法达到关机目标。

[stdcall]

//2000关机
unit Unit1;

interface

uses
Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
StdCtrls;

type
TForm1 = class(TForm)
Button1: TButton;
procedure Button1Click(Sender: TObject);

private
{ Private declarations }
procedure AdjustToken;
public
{ Public declarations }
end;

var
Form1: TForm1;

implementation

{$R *.DFM}

procedure TForm1.AdjustToken();
var
hdlProcessHandle : Cardinal;
hdlTokenHandle : Cardinal;
tmpLuid : Int64;
tkpPrivilegeCount : Int64;
tkp : TOKEN_PRIVILEGES;
tkpNewButIgnored : TOKEN_PRIVILEGES;
lBufferNeeded : Cardinal;
Privilege : array[0..0] of _LUID_AND_ATTRIBUTES;
begin
hdlProcessHandle := GetCurrentProcess;
OpenProcessToken(hdlProcessHandle,
(TOKEN_ADJUST_PRIVILEGES Or TOKEN_QUERY),
hdlTokenHandle);

LookupPrivilegeValue('', 'SeShutdownPrivilege', tmpLuid);
Privilege[0].Luid := tmpLuid;
Privilege[0].Attributes := SE_PRIVILEGE_ENABLED;
tkp.PrivilegeCount := 1;
tkp.Privileges[0] := Privilege[0];
AdjustTokenPrivileges(hdlTokenHandle,
False,
tkp,
Sizeof(tkpNewButIgnored),
tkpNewButIgnored,
lBufferNeeded);

end;
procedure TForm1.Button1Click(Sender: TObject);
begin
AdjustToken;
ExitWindowsEx((EWX_SHUTDOWN Or EWX_FORCE Or EWX_REBOOT), $FFFF);
end;

end.
