利用DLL扩展Visual FoxPro硬件驱动能力

Expand the Driving Ability of Hardware for Visual FoxPro by Using DLL

在 Windows环境下利用 VC+ +编写动态链接库 ,可用于对硬件端口进行访问 ;还可用 VFP主程序调用动态链接库函数 ,实现 VFP对硬件的驱动 .

This article provides a method regarding the development of dynamic link library through visual c++ language for accessing the ports of hardware,and introduces main procedure programming by Visual FoxPro calling functions in the dynamic link library to realize the driving of hardware for Visual FoxPro.
