用MFC来编写的动态链接库，演示了三种形式的链接(To write with MFC dynamic link library that demonstrates three forms of links)

一个禁用U盘的程序,通过修改注册表键值实现禁用USB(A disabled U disk program)

设置列表控件的显示方式，VC++精选编程源码，很好的参考资料。(Set display mode list control, VC++ programming source code, a good reference.)

说明：  关于mapx的表现非常好，请放心使用Tracing not turned on. Tns error struct: nr err code: 0 ns main err code: 12541 TNS-12541: TNS：无监听器 ns secondary err code: 12560 nt main err code: 511 TNS-00511: 无监听器 nt secondary err code: 61 nt OS err code: 0 (on MapX done very well, please rest assured that the use of Tracing not turned on. Tns error struct : nr err code : 0 ns main err code : 12541 TNS-12541 : TNS : None sniffers ns secondary err code : 12560 nt main err code : 511 TNS-00511 : no sniffers nt secondary err code : 61 nt OS err code : 0)

Unicode编码转换器，输入Unicode字符，可以转换成相应的汉字，使用VC6.0编写，有MFC界面，代码测试绝对可以正确运行。(Unicode encoding converter, input Unicode characters can be converted into the corresponding Chinese characters, using VC6.0 prepared with MFC interface, code testing can definitely run correctly.)

可以参考直接使用S7协议连接西门子plc(You can refer to the direct use of the S7 protocol to connect SIEMENS PLC)

VB多光驱智能检测的CD播放机,有需要的就下载吧。(VB drive more intelligent detection of CD player, has the need to download it.)

串口调试助手VB.zip 我想大家都用过 串口调试助手， 也都期望自己能够制作出同样的通信界面； 那么这里的工具，让你如愿…… 采用VB编程，超级简单实用。(Serial debugging assistant VB.zip I would like that we have used serial debugging assistant, also expect to be able to produce the same communication interface where the tool that allows you to do so ... using VB programming, super simple and practical.)

zoj094 Matrix multiplication problem is a typical example of dynamical programming. Suppose you have to evaluate an expression like A*B*C*D*E where A,B,C,D and E are matrices. Since matrix multiplication is associative, the order in which multiplications are performed is arbitrary. However, the number of elementary multiplications needed strongly depends on the evaluation order you choose. For example, let A be a 50*10 matrix, B a 10*20 matrix and C a 20*5 matrix. There are two different strategies to compute A*B*C, namely (A*B)*C and A*(B*C). The first one takes 15000 elementary multiplications, but the second one only 3500. Your job is to write a program that determines the number of elementary multiplications needed for a given evaluation strategy.
