一个不错的Grid组件,其中dtxfull要用到该组件(A good Grid components, including dtxfull should use the component)

Virtual虚函数用法(Virtual virtual function usage)

说明：   c primer plus课后题源程序代码

绘制图形，VC++精选编程源码，很好的参考资料。(Graphics rendering, VC++ select programming source code, a good reference.)

VC根据DirectX的截图示例源码下载,你看懂了话都能截图了。要编译此程序需DirectX SDK5.0示例中的ddutil.h与ddutil.cpp文件,请自行参加工程，VC++编程学习源码，很好的参考资料。(VC according to the DirectX screenshot example source code download, you read the words can screenshot. To compile this program requires DirectX SDK5.0 example of ddutil.h and ddutil.cpp files, please participate in the project, learning VC++ programming source code, a good reference.)

说明：  利用（μ,λ）演化策略求解Ackley函数极小化问题。主要包括种群初始化、重组、变异、（μ,λ）存活选择四个步骤来进行求解。(The evolution strategy is used to solve the minimization problem of Ackley function It mainly includes four steps 1 population initialization 2 recombination 3 mutation 4 survival selection.)

ree(void *p)函数是用来释放程序动态申请的内存。其参数是个指针类型。在C当中，只有当使用了动态内存申请函数malloc calloc realloc申请内存之后，才可以使用free来释放之。释放之后就不能再使用了。(ree (void* p) function is used to release the program dynamically allocated memory. Its argument is a pointer type. In C, only apply when using the dynamic memory functions malloc calloc realloc application memory before you can use free to release it. After release no longer use.)

说明：  调用可执行程序，C语言进行输入，得到基于GIM格网的电离层总电子含量(The total electron content of the ionosphere based on GIM grid is obtained by using executable program and C language for input)

This function generates an Additive White Gaussian Noise (AWGN) sample at every call. Its beauty lies in its simplicity! The generated sample set will have zero mean and a standard deviation of 1. Therefore, one can simply scale the output samples by a different standard deviation to generate different noise profiles. To do this scaling, simply multiply the sample with the standard deviation of your choice. This is a very versatile function that can be used in communication system simulations and random number generation in various applications. I have used it in the past while working with channel encoder and decoder simulators.
