组态软件绘图系统的VC设计与实现

Design and Implementation of Drawing System for Configuration Software by VC Programming

组态软件主要面向工程监控与数据采集,绘图系统是组态软件的重要组成部分,为用户提供组态软件使用的图形界面。讨论了运用VC编程与数据库技术设计和实现组态软件绘图系统的过程,其中主要涉及到VC中MFC编程与SQL Server数据库的配置与使用。整个图形系统以5种基本图形元素的绘制为设计基础,并以此开发建立相应的数据源,取得了较好的实用效果。

Configuration software mainly contributes to the engineering supervisory control and data acquisition, drawing system is one of its important parts and is uesed to offer visual interfaces for users. This paper tries to develop such system by applying techniques about VC programming and SQL Server database application. The design method incorporates MFC concepts and drawing data usage in database tightly. Five types of graphical elements consist of the basic drawing components throughout the process, and the relative source data are developed. The current results are promising and provides sufficient functions for practical research and application.
