FileGDBAPI学习

环境：vs2010 win7_64

首先可以在官网上下载对应版本的源码及例子
这里贴出官网下载地址http://appsforms.esri.com/products/download/#File_Geodatabase_API_1.3（下载速度比较慢）
这里我贴出我的环境对应的（点击下载）（密码：e4wl）
熟悉并编译例子
下载的压缩包解压后，可以看到如下文件链接：

其中 /bin目录下主要包含我们调用API函数需要的.dll文件 /bin64 64位程序使用
/doc目录下包含完整的api介绍文档，建议详读
/include目录下包含所需的头文件，我们的项目中需要添加引用
/lib目录下主要包含需要使用的库文件
/samples目录下是C++调用API的例子
/samplesC#目录下是C#调用API的例子
OpenTK.dll和OpenTK.GLControl.dll是C#例子中要添加引用的dll（我自己下载源码编译得到的，顺便就放过来了）
用VS2010打开C++解决方案，解决方案如下图：

然后打开项目属性，确认包含目录和库目录是否正确：对应的include目录和lib目录

查看项目输出目录：

确保上面的提到的dll放入到该输出目录。
然后就可以点击生成并运行：
如果生成成功但运行时报以下错误：

是因为缺少vs2008运行时环境（点击下载），将其放在生成目录下，或者windows下的System32中
运行成功后得到如下结果：
利用API开发拷贝功能
这里主要编写了一些简单的Copy功能，可能实现不够完善，希望能够有大神指导。
拷贝整个FileGDB数据库，分两种方式
1.通过文件夹拷贝方式，详情参见
2.通过调用FileGDBAPI所提供的API：
实现比较简单，大致想法是细化问题，先实现拷贝要素函数、利用该函数实现拷贝要素数据集函数，然后利用上述两个函数实现整个数据库的拷贝。
这里贴出源码：

这里记得将FileGDBAPID.dll(Debug版)放到工程输出目录下，并且在引用目录中加入需要加入的.h文件，以及添加工程库目录并在输入中加入FileGDBAPID.lib（Debug版）。
4. 封装成类库项目并编写demo调用

这里要用到C++类库项目开发的一些知识，详情见我的另一篇博客：
