ArcGIS Engine开发的ArcGIS 版本管理的功能
来源：互联网 发布：七号淘宝外设店 编辑：程序博客网 时间：2024/05/16 08:39
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：
------------------------------------------------------------------
系统环境：
VS2010、ArcGIS Engine10、DevExpress721（第三方控件，比较常用易于下载）
------------------------------------------------------------------
我跟大家分享了存在#百度网盘#上的文件，“DXperienceEval-7.2.1.exe”，点击链接进行查看和下载。 http://t.cn/zWsdZRY （分享自 @百度网盘官方微博）------------------------------------------------------------------
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！
