另类模拟按键，易语言源码，供易语言初学者参考。

用Qt写的例子，可以用鼠标直接在上面画画，不时会自动删除画什么的

Regression是一款进行多元线性回归分析的计量经济学软件.可以完成多元回归模型的参数估计和统计检验和计量经济学检验.可以通过Excel获取外部数据,并且能够把计算结果保存成xls文件，计算结果的差方图和平面图都可以保存成bmp文件。另外，也可以针对某一列数据进行数据处理。-A multivariate linear regression analysis of econometric software. To be completed Multiple regression model parameter estimation and statistical testing and econometric testing. Excel can access external data , and be able to calculate the results into Excel document preservation, The results of the poor and to map plans can be preserved as bmp document. In addition, it may be against a disaggregated data for data processing.

求阶乘算法（0---10000）标准C++语言控制台应用程序 可能很多人都曾经想过要实现一些比较大的数的阶乘，但是C++中提供的标准数据类型其存储空间太小，根本无法实现。我们可以通过其他方法来实现，本程序用一个很简单的算法实现数的阶乘，程序很短，也很简单，各处都有注释，相信大家很容易就可以看懂，下载源码后在VC6.0中打开编译后即可运行，程序经少许改动可以实现更大的数的阶乘，有兴趣的读者在看完本程序后可一动手试试，其乐无穷！！希望这个程序能给大家一点帮助-The arithmetic for counting factorial(0-10000) This is a standard C++ language console application, many people could want to relize the factorial of some large numbers, but the memory space of the standard data type provided by the C++ is too small, so it can not realize at all. But we can realize it by other method, the program realize the factorial of the number you give by a simple arithmetic ,this is a short and easy program, and there are remarks everywhere, I believe that everyone can easily understand it, after downloading the sound code you can open it in VC6.0, then edit and run it. you also can change something to realize the factorial of a larger number, the reader who is interesting in it can have a try, there are more happiness in it!! At last,
