说明：  VC++编程实现网络嗅探器 简单 但是完整可运行。比较基础(VC++ programming for network sniffer)

C语言实现217卷积码的viterbi译码（软、硬判决的代码都有，运行时先在VC中分别运行软、硬判决的C程序，产生误比特率的数据并存储在.txt文件中，之后在matlab中读取数据，画出误比特率曲线，matlab程序也已给出）(C language achieve 217 viterbi decoding (including hard and soft decision,and the codes should be run in VC to generate and store the BER datas,and the to obtain BER curve in matlab))

基于跟新后的linux内核的scull驱动代码及详解(Based on post with the new linux kernel driver code and Detailed scull)

说明：  实例：消除rice.png图像中亮度不一致的背景，并使用阈值将修改后的图像转换为二值图像，使用成员标记返回图像中对象的个数以及统计特性。按照如下步骤进行： (matlab image)

用wmsdk写的asf文件异步读取的例子，可以应用与网络视频分发，接收，很好用！(Written by wmsdk asynchronous read asf file example can be applied to video and network distribution, reception, very good use!)

捕获局域网内的数据包，并从中的到数据，和相关信息，没开线程，我vc初学，欢迎朋友对它改进，别忘发我一份fecon@tom.com，用winpcap捕获.先安装winpcap3.1，注意改一下opnion里的lib路径(capture the data packets to and from the data, and related information, not open threads, I vc beginners welcome friends to improve it, do not forget that I made a fecon@tom.com with winpcap capture. Install winpcap3.1, to change it's lib opnion Path)
