：通过用VC编写动态链接库DLL，并在VB中调用DLL的方式，借助计算机自带网卡和企业的

内部网络实现了测量数据的网络传输。给出了具体的设计思想和整个过程，介绍了VC下的网络编程

技术和DLL编程技术，给出了在VB下加载DLL的具体方法，对工业在线测量仪器实现网络化、信息化

具有很好的借鉴作用。-: VC prepared by using the dynamic link library DLL, and call the DLL in the VB approach, using computer network card comes with the enterprise' s internal networks and the measurement data network. Given the specific design ideas and the whole process, introduced the network programming under VC and DLL programming, under the given load the DLL in the VB specific methods of measurement instruments for industrial realization of online networking, information technology has a very good reference.
