基于VC++6.0的工业监控软件中历史曲线控件的开发

The Development of the History Curve Control of Industrial Monitor Software Based on VC++ 6.0

文章阐述了运用VC+6.0对监控系统软件中非标准历史曲线控件的开发方法及思路,并介绍了历史数据库的设计。控件采用Activex技术,能同时显示8根曲线,并能根据需要隐藏任何一根曲线;使用时,只需将其注册,拖到界面程序中去即可,而不需要再次编写任何源代码。该方法具有广泛的适用性,可应用于各种监控软件的数据存储和进线的动态显示。

The paper expounds the development method and the train of thought in the application of VC ＋ ＋ 6.0 to non - standard history curve control of monitor system software and introduces the design of history database. By means of Activex technology, the control can show 8 curves and hide any curve. When one uses the control, he simply registers and drags it to the software interface. It is unnecessary to compose the original code. This method has a wide application and it can be used in the data storage of various monitor software and the dynamic display of curves.
