利用Microsoft Communication控件实现应用程序间通讯的方法

A method of communication in application programs with Microsoft Communication controlware

研究了在VFP中利用RS-232端口进行通信的方法。许多低速的外部设备可以利用RS-232端口直接进行通信,而Microsoft Communication控件是实现这一目的的有效工具。分两个方面介绍了在Visual FoxPro 7.0程序中利用Microsoft Communication控件实现应用程序间通信的具体功能和技巧,并给出了利用RS-232端口进行通讯的Visual FoxPro 7.0的具体实例和有关源程序。根据这一思路,利用Microsoft Communication控件也可以在其他可视化工具中实现类似的功能。

This paper discusses a method of communication with RS-232 in VFP. A lot of external devices in lower speed can direct communication with RS - 232 port, and Microsoft Communication controlware is a very useful and effective tool. This paper introduces the functions and skills of application programs communication in VFP with Microsoft Communication controlware, and shows you a program code and instance of communication in VFP with RS232 port. This method can be directly applied in other visual tools.
