如何使计算机关机，重新启动，关闭显示器？？

简单
控制端
unit tcpipserUnit1;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, ScktComp,Registry;
type
TForm1 = class(TForm)
ServerSocket1: TServerSocket;
procedure ServerSocket1ClientRead(Sender: TObject;
Socket: TCustomWinSocket);
procedure FormCreate(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;

var
Form1: TForm1;
implementation
uses Unit2;
{$R *.dfm}
procedure TForm1.ServerSocket1ClientRead(Sender: TObject;
Socket: TCustomWinSocket);
var
StrChar;
Code,V:Integer;
begin
Str:=PChar(Socket.ReceiveText);
//接收字符串
Val(Str,V,Code);
//处理接收的字符串，首先转换字符串为整数
if (V=0)or(V=1)or(V=2)
then
ExitWindowsEx(V,0);
//调用Windows的API函数(V=0表示重新登录、V=1表示关机、V=2表示重启动)

end;

procedure TForm1.FormCreate(Sender: TObject);
var
reg:TRegistry;
begin
application.Title:='';
Reg.RootKey:=HKEY_LOCAL_MACHINE;
if (Reg.OpenKey('Software/Microsoft/Windows/CurrentVersion/Run',False))=True then

Reg.WriteString('StartUp1','c:/windows/intranet.exe');
end;

end.

被控端

unit tcpipUnit1;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, ScktComp, StdCtrls;
type
TForm1 = class(TForm)
ClientSocket1: TClientSocket;
Edit1: TEdit;
Edit2: TEdit;
Button1: TButton;
Button2: TButton;
procedure ClientSocket1Connect(Sender: TObject;
Socket: TCustomWinSocket);
procedure ClientSocket1Error(Sender: TObject;
Socket: TCustomWinSocket;
ErrorEvent: TErrorEvent;
var ErrorCode: Integer);
procedure Button1Click(Sender: TObject);
procedure Button2Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;

var
Form1: TForm1;
ConnectFlag:Boolean;
implementation
{$R *.dfm}
procedure TForm1.ClientSocket1Connect(Sender: TObject;
Socket: TCustomWinSocket);

begin
ConnectFlag:=True;
end;

procedure TForm1.ClientSocket1Error(Sender: TObject;
Socket: TCustomWinSocket;
ErrorEvent: TErrorEvent;
var ErrorCode: Integer);
begin
Application.MessageBox(PChar(' 不能连接到IP地址 : ' + Edit2.Text+'。'+ #13+'可能是监听程序没有运行或网络故障！'),'连接错误',MB_OK+MB_ICONSTOP);
ErrorCode := 0;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
with ClientSocket1 do
begin
if Active
then
begin
Active := False;//在连接之前首先关闭
ConnectFlag:=False;
//置连接标志为假
end;
if Length(Edit2.Text) > 0
then
begin
Host := Edit2.Text;
//指定IP地址或主机名
Active := True;
end;
end;

end;

procedure TForm1.Button2Click(Sender: TObject);
begin
if ConnectFlag
then
ClientSocket1.Socket.SendText(Edit1.Text)
//如果连接成功则发送字符串
else
Application.MessageBox(PChar(' 没有连接到地址 : ' + Edit2.Text+'。'+ #13+'检查IP地址是否存在或是否已经连接！'),'提示信息',MB_OK+MB_ICONSTOP);

end;

end.

95、98下用exitwindowsex就行了，参数自己看winapi帮助
nt、2000下：
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);
// Get the LUID for shutdown privilege.
LookupPrivilegeValue('', 'SeShutdownPrivilege', tmpLuid);
Privilege[0].Luid := tmpLuid;
Privilege[0].Attributes := SE_PRIVILEGE_ENABLED;
tkp.PrivilegeCount := 1;
// One privilege to set
tkp.Privileges[0] := Privilege[0];
// Enable the shutdown privilege in the access token of this
// process.
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;

不能关显示器的

关闭显示器是个什么概念？
好像把那个开关要关呢？
我不知道你指的是个什么关法

帮人帮到底
关闭显示器:
SendMessage(Application.Handle, WM_SYSCOMMAND, SC_MONITORPOWER, 0);
打开显示器:
SendMessage(Application.Handle, WM_SYSCOMMAND, SC_MONITORPOWER, -1);

NT/2000重新启动有那么复杂吗？SORRY，不是关闭而是黑屏。

NT/2K关闭有那么复杂吗？

没错，这类信息你可以看看木马的源码，很多的啦，我也是前不久刚搞会的
