8bit_echo

禁用USB，光驱，注册表，组策略..等，，(Disable USB, CD-ROM drive, registry, group policy .. and so on,)

this is the code on c++ 2005 The program code, which maintains a database. Created two documents, of which is read / write. Function menu, all functions: adding records, search, replace, delete, check availability. Full inheritance. Additional function is Creation a Report to the calculation

用VC编的一个计算器，有界面，适合研究生VC编程初期学习使用(VC series a calculator interface, suitable for graduate student VC program initially learning to use)

Factory 模式的两个最重要的功能： 1）定义创建对象的接口，封装了对象的建； 2）使得具体化类的工作延迟到了子类中。 (Factory mode two most important functions: 1) the definition of an object to create an interface that encapsulates the construction objects 2) makes specific class work delayed to subclasses.)

这是自己编写的一个简易计算器，用于加减乘除计算，还有百分比和平方。(I have written a simple calculator for arithmetic calculations, as well as percentages and square.)

说明：  用c语言实现电机仿真－基于恒定磁链的转子磁链控制。(Using c language realize electrical simulation- based on a constant flux of the rotor flux control.)

VB获取当前日期时间的一个范例程序,有需要的就下载吧。(VB to get the current date and time a sample program, there is a need to download it.)

读取文件。给出一个txt文件（水准数据）利用openfile 语句读取每一行的文件，再读入数据库。(Read the file. Gives a txt file (level data) to utilize openfile statement reads each line of the file, and read it into the database.)

k在VC中对话框程序中实现切分窗口的控件类,不错的源码(K in VC dialog box procedure of segmentation window in the control class, a good source)

说明：  构造最小生成树的常用方法是Prim算法与Kruskal算法，二者都是基于贪心算法设计侧略。(Construction of the commonly used minimum spanning tree algorithm is Prim and Kruskal algorithms, both are based on the design side of a little greedy algorithm.)
