求素数是用C写的#素数球窗口应用。

获取 Windows 外壳窗口的句柄-access to the Windows shell window handle

一个奇怪的代码，SDK时就不会使实参变空，如果是MFC则同样的代码就会使实参变为空，可能值得大家研究研究。-a strange code, the SDK will not do so when it parametric space, If MFC is the same code will enable it to participate in the air, it may be worthwhile for everyone studies.

类似于windows的画图板，基于MFC框架，能够实现文件的保存和读取，画点线圆矩形等，可设置线宽，线形和颜色-Similar to the windows of the drawing board, based on the MFC framework, can be achieved to save the file and read, draw points and lines circle rectangle and so on, you can set line width, linear and color

一个关于模拟火燃烧的例子，用到了最简单的模糊算法。-A fire on the simulation example, using the most simple fuzzy algorithm.

This sample shows how floating-point exceptions may be captured and handled in an MFC application.

这是一个字符串处理函数集，包括： IsNumeric――检查串是否为数字串 Upcase――变成大写串 Lowercase――变成小写串 Trim――截掉串尾的空格 RTrim――截掉串开始处的空格 LTrim――截掉串尾的空格 right――从右到左截掉字符 left―― 从左到右截掉字符 mid――截掉从某个起始位置到右边位置的字符 zip文件中包含StringFunctins.h和StringFunctins.cpp是字符串处理函数的头文件和实现文件，main.cpp和main.h是一个控制台应用程序的头和实现，示范字符串处理函数的使用方法。-this a string functions,include:IsNumeric-check_up if the string is Numeric,Upcase-change to capital string,Lowercase-change to small string,Trim-cut blank of string tail,right-cut character from right to left,left-cut character from left to right,mid-cut character from mid to right,the zip file include StringFunctions.h and StringFunctions.cpp,which is using for string functions,main.cpp and main.h are head and implement of a console program,it demonstate the way of using string functions.
