arcgis engine开发的arcgis 版本管理的效能

更新时间: 2014-01-05 02:04:00 责任编辑: Author_N1

 

ArcGIS Engine开发的ArcGIS 版本管理的功能
这是以前的ArcGIS Engine开发成果,主要是Geodatabase方面的,模仿ArcGIS版本的流程
系统环境:

VS2010、ArcGIS Engine10、DevExpress721(第三方控件,比较常用易于下载)

系统的连接参数都写在代码里面了,如果有问题,跟踪一下代码即可解决

相关功能:

1:打开ArcSDE版本数据

2:切换版本

3:创建新版本

4:查看版本信息

5:协调版本

6:冲突解决

7:提交版本

8:历史归档管理


因为这是很早的东西了,是自己兴趣开发的,会有相关bug,如果有一定基础肯定可以顺利的进行参考!希望能给大家带来帮助!


仅供参考!
