事情是这样的，我们这里有一台机器可以通过MODEM上网。现在我们要在程序中让系统定时段
线。
假设我现在作个隐藏的程序，在系统启动时运行。假设系统启动后，有人通过MODEM拨号163
上网，而程序要做的是在晚上10：00让机器自动断线(不重新启动)。
这个有办法吗？是通过API还是系统设置呢？
 
有现成的软件 MyHelper(我的助手)
http://www.helperstudio.com/Software/Myhelper/Index.asp
可以定时做很多事，比如提醒、执行程序(任意指定)、关闭程序(任意指定)、上网、下网、
关机、待机、开关光驱等等，占用系统资源不大，还有很多别的实用功能，真的能成为你的
好助手。我一直在用它。
 
我是通过用程序来做,我知道用API函数可以的,我的系统市WINDOWS 98.
有谁知道吗
 
放在WINDOWS的计划任务里不就OK 了？
 
我是通过用程序来做,我想知道怎样用API函数让系统下线,我的系统市WINDOWS 98.

打开拨号连接

调用拨号网络里的拨号程序来连接：其中'连接Internet'为你创建的拨号程序名称
winexec('rundll32.exe rnaui.dll,RnaDial '+'连接Internet',9);

 
上面的没有试过
下面的用的是RasAPI
挂断拨号连接的RasAPI函数为RasHangUp，其函数原型为：
function RasHangUp(
hRasConn : DWORD//要挂断的拨号连接的句柄
) : DWORD; stdcall;
function RasHangUp;external RasApiDll name 'RasHangUpA';
函数返回值为0表示执行成功；否则为错误代码．
下面是一个应用例子，挂断由RasDial建立的拨号连接．

//挂断由RasDial建立的拨号连接
dwResult := RasHangUp( RasCon );
if dwResult <> 0 then //挂断失败
memo1.lines.add( '挂断失败：' + GetRasError( dwResult ))
else
memo1.lines.add( '挂断成功！');
 
这是我做的一个远程断网的程序：
服务器端：

上面的程序在2000、Isdn上通过。在98、Modem的情况下是一样的。

像你的应用写成NT服务就更好了，如果你是用2000的话。

 
TO 远帆:
你的例子是完整的吗，首先你的程序里面引用的两个文件(SafeSockU, RasApi)就找不到，提示
错误,我在所有硬盘上找都没有找到，你的程序你通过了？
 
Sorry。
RasApi是ras的接口单元。
SafeSockU是我自已写的利用UDP协议传送数据的DLL的接口单元。

RasApi我贴在下面

to 远帆兄:
我把你的程序已经考过来调通了,目前逻辑上面已经没有错误.
我拨号上线,在程序运行的时候,跟踪查看发现:RasEnumConnections(@entries[1], bufsize, numEntries)
的结果为0,证明是成功执行了,但是numEntries的值也为0,也就是没有检测到活动的连接,
也不能让程序断线,怎么回事呢?
 
这样？我也不太清楚了。
