跨平台集成开发方法在河道信息系统中的应用

Application of integrated cross-platform development method in River Across Information System

为开发出功能强、使用方便、界面友好的GIS应用软件 ,采用了跨平台集成方法 ,即用进程间的通讯技术 ,通过可视化软件开发工具VisualBasic 6 .0开发前台可执行应用程序 ,用对象链接嵌入自动化方式启动后台地理信息系统软件 ,以实现应用程序中的地理信息系统功能。同时结合河道信息系统应用实例 ,给出了实现MapInfo功能的程序。

For developing a GIS application software with strong functions, convenience use and friendly interfaces, an integrated cross platform method was employed, i.e.,a communication across processes technology by which two or over two Windows application programs can simultaneously receive and transmit informations.By means of visual software development tool(Visual Basic 6.0 )to develop practicable application program in front platform,using OLE Automation way to start geographic information system software in back platform,the functions of geographic information system in the application program can be realized. In combination with an illustration on a river information system, a program to accomplish MapInfo functions is given.
