电信拨号器

　　公司用的是电信的网络，前段时间公司的电脑总是拨不上去号，自己写了一个基于Java的电信拨号程序，感兴趣的朋友可以下载下看看。

　　下面是拨号程序的原代码，大家可以看看，有什么不合理的地方请指出来。

你也可以自己运行一下代码，不过请确定你的网络是电信的。

基本看完了lz的代码，觉得想法是好的，顶一个。当然代码也不错。

晕，兄弟对不住呀，刚把代码给发上过，不好意思啦。

基于Windows的rasdial吧?

貌似你程序还写错了

p = Runtime.getRuntime().exec((new StringBuilder("rasdial.exe ")).append(user).append(" ").append(conNum).append(" ").append(password).toString());

        rasdial.exe entryname [username [password|*]] [/DOMAIN:domain]
                [/PHONE:phonenumber] [/CALLBACK:callbacknumber]
                [/PHONEBOOK:phonebookfile] [/PREFIXSUFFIX]

        rasdial.exe [entryname] /DISCONNECT

        rasdial.exe

或者说 你变量名取的比较变态

你还不如写一个批处理呢

你还不如写一个批处理呢

批处理，我也写的有呀，不过是兴趣所致，写一个玩玩，让大家共享下。

没什么出彩的地方，以前用asm写过一个，因为学校的用户名经过md5的。。。
