这是一个基于CUDA的光线追踪Demo演示，运行后按回车可以看到结果。(This is a demo based on CUDA for ray tracing. After running the program, please press the enter key to see the results.)

这个源码是运用ado方式连接数据库的例子其中实现方式是利用ado类中的方法。运用C++实现(Examples of this source is to use ADO to connect to the database using C++ achieve)

进行加法运算的实例程序，是照着别人的做的，如果有初学者可以看看。(An example program for adding operations is based on what others do, if you have a beginner.)

说明：  新安江模型，应用遗传算法用于参数的自动率定(The Xin'An river model with genetic algorithm)

电机内电磁场分析计算程序，适合于旋转永磁同步电机或直线电机(Motor electromagnetic field analysis and calculation procedures )

nRF24L01示例程序，官方的，试验通过。(nRF24L01 sample program, the official trial through.)

删除指定目录下某种类型的文件，VC++精选编程源码，很好的参考资料。(Delete the specified file is a type of directory, VC++ select programming source code, a good reference.)

COM组件的聚合，其中有两个组件，A为内部组件，B为外部组件(COM components aggregate)

说明：  呼叫阻塞率的计算和仿真：在时间轴上考虑。无论阻塞与否，下一呼叫到达时刻为当前呼叫到达时刻加上服从参数为1/λ的指数分布的呼叫间隔时间。一个呼叫到达时只需要判断呼叫的到达时刻和各个信道服务完成时刻的先后：如果前者比后者中任意一个大，说明至少有一个信道服务完成时刻比此呼叫到达时刻早，即此信道空闲，此时呼叫成功，应该先把此信道下一个服务完成时刻置为当前呼叫到达时刻，再加上服从参数为μ的指数分布的服务时间；反之，如果前者比后者中全部都小，说明所有信道在此呼叫到达后才会结束服务，即当前忙，此呼叫被阻塞掉了(call blocking probability calculation and simulation : the time frame to consider. Whether or not blocked, the next call arrived at the present moment to call time arrived with a subordinate parameters/ index distribution of the call interval. A call arrived only judgment call and the arrival time each channel service has completed a moment : If the former than the latter an arbitrary, and at least one channel is completed service calls than this moment arrived moments earlier, that this channel is idle, call this success, should first get here Channel a moment of complete services for the current call home arrival time, coupled with the parameters obey the exponential distribution services; Conversely, if the former than the latter, all small, with all the Channel call arrived only aft)

一个网络后门程序。演示了通过Http通道的功能穿透安全级别非常高的防火墙，甚至硬件防火墙。()
