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Visual Basic 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.
