利用VB通信控件实现GRE4与计算机间数据通信

Carrying out the communication between GRE4 and computer by using VB communication control component

介绍了利用 ＶＢ５． ０中的 ＭＳＣｃｏｍｍ通信控件编程，实现ＧＲＥ４电子手簿与计算机间的数据通信。该程序以 Ｗｉｎ９８为平台，采用图形用户界面，使用简单，操作方便，对子发挥ＧＲＥ４在数字化测图方面的作用有一定的现实意义。

This paper introduces a program by using VB5. 0 in MSCcomm communications control component so as to realize the data communications between GRE electronic field book7 and computer. The program tables the Win98 as its platform and adopts graphy user interface. It is simple in use and convenient in operation. The program has an important practical significance to bring the GRE4 into full play in digitalized mapping.
