前段时间，朋友送了一个无线网卡，本想用无线网卡做一个WIFI热点，但是发现学校的Netkeeper禁止了网络共享，加上对学校外网收费不满，所以自己用Qt和Rasapi32.dll写了一个拨号程序，完全实现了Netkeeper，破除了无线共享的限制。 如果需要源码的请邮件[email protected]

编程珠玑，内容不做介绍了，程序员你懂的！没有读过，没有考虑过，算程序员吗？

结构之法算法之道最新全部锦集，数据结构程序的基础，算法程序的灵魂。程序员必读的精彩博文汇总。

应聘面试互联网商的同学们注意了，从事互联网必须具备这些知识背景呀！前几天面试腾讯实习生发现很多问题都是大数据处理的。早做准备是必须的

C++实现数据结构中各种算法。链表操作，各种树、图、排序等经典算法！

当运行程序或者游戏时，系统弹出错误提示“ 找不到 msvcrtd.dll”,或者“ 没有找到 msvcrtd.dll”时，说明您系统中缺失这个dll文件或者该dll文件没有被注册，您需要下载该文件将其解压到相应目录并注册它。 dll文件如何安装？ 通常是将 dll文件复制到“ X:\Windows\system32 ” (X代表您系统所在目录盘符，如：C:\Windows\system32 ) 目录下。

当运行程序或者游戏时，系统弹出错误提示“ 找不到 mfco42d.dll”,或者“ 没有找到 mfco42d.dll”时，说明您系统中缺失这个dll文件或者该dll文件没有被注册，您需要下载该文件将其解压到相应目录并注册它。 dll文件如何安装？ 通常是将 dll文件复制到“ X:\Windows\system32 ” (X代表您系统所在目录盘符，如：C:\Windows\system32 ) 目录下。
