上篇我们说到了如何实现登陆，但是腾讯对某一个IP在某一段时间的登陆行为存在检测，对于存在异常的IP会出现验证码，但是腾讯的验证码比较难识别，或许是我对图形识别(匹配)的技术还认识的不够深刻。C#/Java技术交流群：96020642，传送门：Rolends
噪线，倾斜，字符连接，镂空，噪线字符同色.这些都是识别的难点，具体的算法我试过，识别成功率很低，技术不够没办法，好了偏题了，还是说ADSL拨号的实现ADSL拨号需要调用windows api来实现。
调用RASAPI32.DLL
（三）C# QQ讨论组广告群发工具——ADSL 拨号实现（附源码）
ADSL的所有操作都要调用这个dll，详细的调用方法和参数，大家可以查询MSDN
不过对于我这种懒人，明白了原理，能使用拿来主义就拿哦
在codeplex上有个叫dotras的项目http://dotras.codeplex.com/这个项目封装了rasapi dll的操作，大家可以下载下来使用，不用自己在封装了，关于操作方法可以参见实例，下载过来后有示例的：
