一些matlab的程序，初学数字信号处理时的联系用，是经典书籍的答案(small)

可实现对进程的模拟管理,用VC编的,结果可间隔一秒显示(can be simulated in the process of management, VC series, the results can be shown at one-second intervals)

说明：  用MFC做的一个小的绘图软件，简单实用，适合初学者参考使用。(MFC to do with a small graphics software that is simple and practical reference for beginners.)

基于51单片机的步进电机的控制设计 一圈360度,需要20个脉 冲完成. 3,步进电机具有瞬间启动和急速停止的优越特性. 4,改变脉冲的顺序,可以方便的改变转动的方向(51 step motor control designs around 360 degrees, requires 20 pulses to complete. 3, stepper motor with instant start and stop the rapid superior characteristics based on 4, change the order of the pulse, you can easily change the direction of rotation)

使用Visual C++ 或Visual Studio集成开发环境与Socket API,使用C++编程语言,设计并实现了一个简单的点对点的多线程网络聊天软件,使用多线程实现数据的收发(Using Visual c++ or Visual Studio integrated development environment and the Socket API, using c++ programming language, designed and implemented a simple point-to-point multi-threaded network chat software, using multi-threaded send and receive data )

可以实现无线通信，代码简单便于理解，是基于wince平台的(Wireless communications can be achieved, the code simple and easy to understand, is based on the wince platform)

该源代码是我精心为朋友准备的，涵盖了各种调用方式和编译方式，花了半个月的业余时间，很高贵啊(The source code is for a friend I painstakingly prepared, covering a variety of ways and the compiler calls the way of spare time to spend half a month, a high贵啊)

VC TreeView树控件的应用(拖放、删除、添加、重命名)，精选学习源码，很好的参考资料。(Application of VC TreeView tree controls (drag and drop, add, delete, rename), select learning source code, a good reference.)

题目：取一个整数a从右端开始的4～7位。 程序分析：可以这样考虑： (1)先使a右移4位。 (2)设置一个低4位全为1,其余全为0的数。可用~(~0<<4) (3)将上面二者进行&运算。 2.程序源代码：(Topic: take an integer a from the right end of the four to seven began. Program analysis: it can be to consider: (1) to make a move to the right four. (2) sets a low four total for the 1, all the rest for 0 of the number. Can be used to (~ 0 < < 4) (3) will above the difference and operations. 2. The source code:)
