动态链接库：LB_DES 项目概述

========================================================================

应用程序向导已为您创建了此 LB_DES DLL。

本文件概要介绍组成 LB_DES 应用程序的

的每个文件的内容。

LB_DES.vcproj

这是使用应用程序向导生成的 VC++ 项目的主项目文件，

其中包含生成该文件的 Visual C++ 的版本信息，以及有关使用应用程序向导选择的平台、配置和项目功能的信息。

LB_DES.cpp

这是主 DLL 源文件。

此 DLL 在创建时不导出任何符号。因此，在生成此 DLL 时

将不会产生 .lib 文件。如果希望此项目

成为其他某个项目的项目依赖项，则需要

添加代码以从 DLL 导出某些符号，

以便产生一个导出库，或者，也可以在项目“属性页”对话框中的

“链接器”文件夹中，将“常规”属性页上的

“忽略输入库”属性设置为“是”。

/////////////////////////////////////////////////////////////////////////////

其他标准文件：

StdAfx.h, StdAfx.cpp

这些文件用于生成名为 LB_DES.pch 的预编译头 (PCH) 文件和名为 StdAfx.obj 的预编译类型文件。

/////////////////////////////////////////////////////////////////////////////

其他注释：

应用程序向导使用“TODO:”注释来指示应添加或自定义的源代码部分。

/////////////////////////////////////////////////////////////////////////////

下面发布每一个文件代码

把以上代码编译成功后会产生DLL文件，先用反编译工具查看是否先函数编译成功并且导出，正确导出如图所示：

至此算法函数完成，只要在相关应用中调用即可；

另附加源码包；
