VB调用WebService源码

VB采用最小二乘法演示如何在VB中实现线性拟合和二次拟合，编译时候需要TeeChart5.ocx，已将此文件打包，你无需再下载。新建 Microsoft Excel 工作表.xls里是测试数据，程序会自动读龋这里要说的是： 　　1.1 线性拟合：给定一组数据（xi，yi），i=1，2，…，m，做拟合直线。 　　1.2 二次拟合：给定数据系列（xi，yi），i=1，2，…，m，用二次多项式函数拟合这组数据。作出拟合函数与数据序列的均方误差最校 (VB using the method of least squares linear fit and demonstrates how to implement a quadratic fit in VB compiler when needed TeeChart5.ocx, has packed this file, you do not need to download. Newly built in Microsoft Excel worksheet xls test data, the program will automatically read caries say here is: 1.1 linear fit: Given a set of data (xi, yi), i = 1,2, ..., m, do fitting a straight line. 1.2 quadratic fit: given data series (xi, yi), i = 1,2, ..., m, with a quadratic polynomial function fitting this set of data. Fitting function to the data sequence with the best mean square error correction)

这是一个很基础的小系统，里面有一些添加成绩，删除成绩，和查询成绩功能，但不适合实用，只是了解如何运用控件和参数还有MFC(This is a very basic systems, there are some achievements to add, delete results, performance and query functions, but not for practical, just learn how to use the controls and parameters as well as MFC)

说明：  Diffie-Hellman:一种确保共享KEY安全穿越不安全网络的方法，它是OAKLEY的一个组成部分。Whitefield与Martin Hellman在1976年提出了一个奇妙的密钥交换协议，称为Diffie-Hellman密钥交换协议/算法(Diffie-Hellman Key Exchange/Agreement Algorithm).这个机制的巧妙在于需要安全通信的双方可以用这个方法确定对称密钥。然后可以用这个密钥进行加密和解密。但是注意，这个密钥交换协议/算法只能用于密钥的交换，而不能进行消息的加密和解密。双方确定要用的密钥后，要使用其他对称密钥操作加密算法实际加密和解密消息。(DH Protocol source code)
