在进行软件开发的过程中，如何在不同的编程工具之间进行数据交换和通讯，需要进行不断的探索和总结。我们在开发机械CAD仿真软件的过程中，遇到了在VC++中读取和修改Visual Foxpro中数据的问题。经过许多次的试验，我们通过采用自动服务器（ActiveX Automation）的方法圆满解决了这个问题。-During the software development process, how different programming tools for data exchange between and telecommunications, the need for continued exploration and summary. We are in the development of mechanical CAD simulation software encountered in the course of the VC++ Read and modify data in Visual Foxpro problems. After many times of trial, we adopted the use of auto-server (ActiveX Automation) approach a satisfactory solution to this problem.
