自动关机，在delphi里面可以做出来么？ (50分)

自动关机，在delphi里面可以做出来么？ 最好有代码

可以啊，用定时嚣判断时间，时间一到则关机即可。
我现在在外面上的，没有代码，回去再给你。
或者给个邮箱也行。

luckhacker：也给个例子给我吧！firedrong@163.com

用个winapi函数ExitWindowsEx就可以了。

ExitWindowsEx(EWX_SHUTDOWN, 0);

exitwindowsex(ewx_reboot,0);
exitwindowsex(ewx_shutdown,0);
不过关机命令要主板支持才能实现。

在win2000下，比较复杂。。。
查以前资料。。。

萧西风，接收！
lwzl99，找萧西风要吧！

用函数ExitWindowsEx(EWX_SHUTDOWN or EWX_POWEROFF,0);

加上一个timer，然后在它的ontimer事件中写下：
if time>strtotime ('12:00:00') then
exitwindowsex(ewx_force,0);
这样，到了十二点，就会强行关机的！

xjzdy@cnnb.net也想要一份，waitting.....

【声明】
Function ExitWindowsEx Lib "user32" Alias "ExitWindowsEx"
(ByVal uFlags As Long, ByVal dwReserved As Long) As Long

【说明】
退出windows，并用特定的选项重新启动

【返回值】
Long，非零表示成功，零表示失败。会设置GetLastError

【备注】
这个函数调用后会立刻返回，系统关闭过程是在后台进行的。注意先中止自己的应用程序，使关闭过程更显平顺。当然，您的进程必须有足够的优先权，否则也不能执行这种操作

【参数】
uFlags --------- Long，指定下述一个或多个标志（用OR运算符合并到一起）
EWX_FORCE
强迫中止没有响应的进程
EWX_LOGOFF
中止进程，然后注销
EWX_SHUTDOWN
关掉系统电源（如果可能的话，ATX电源就可以）
EWX_REBOOT
重新引导系统
EWX_SHUTDOWN
关闭系统

dwReserved ----- Long，保留，设为零

给你源码，不过我要200分：

这个肯定没有问题，我一直这么用

var
hToken: THandle;

tkpo: TTokenPrivileges;
zero: DWORD;
begin

begin
zero := 0;
if not OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES or TOKEN_QUERY, hToken) then
begin
ShowMsg('OpenProcessToken() Failed', 1);
Exit;
end;
if not LookupPrivilegeValue(nil, 'SeShutdownPrivilege', tkp.Privileges[0].Luid) then
begin
ShowMsg('LookupPrivilegeValue() Failed', 1);
Exit;
end;
tkp.PrivilegeCount := 1;
tkp.Privileges[0].Attributes := SE_PRIVILEGE_ENABLED;

AdjustTokenPrivileges(hToken, False, tkp, SizeOf(TTokenPrivileges), tkpo, zero);
if Boolean(GetLastError()) then
begin
ShowMsg('AdjustTokenPrivileges() Failed', 1);
Exit;
end
else
ExitWindowsEx(EWX_FORCE or EWX_SHUTDOWN or EWX_POWEROFF, 0);
end
else
ExitWindowsEx(EWX_FORCE or EWX_SHUTDOWN or EWX_POWEROFF, 0);

你写的东东是哪儿来的，是电子书上的吗，这样的书在什么地方有下的，
或是你发一个来给我好吗，我给你300分，怎么样！！

不好意思，借个地方问一下。

是我自己做的一个工具，讲述Win32 API的。

靠，无论是ewx_force 还是 ewx_reboot都是注销了事，马马D
