VB与Surfer制作自定义控件绘制多种色斑图的方法

摘要

[目的]研究VB与Surfer制作自定义控件绘制多种色斑图的方法.[方法]以VB与Surfer制作自定义控件绘制多种色斑图的方法为例,介绍了在VB 6.0编程环境下使用自定义ActiveX控件实现数据处理、系统维护与程序编写的分离方法.[结果]在“湖南省现代农业气象业务服务综合平台”的开发过程中由于需要绘制各种不同要求的色斑图,工作量非常大,但使用了编写自定义的ActiveX控件的方法做到了绘图与数据的分离,提高了软件工作效率.[结论]该研究解决了绘制大量色斑图时如何做到减少编程工作量、提高代码利用率、统一软件界面及简化操作的问题.%[ Objective] The aim was to picture choroplethic map through VB and Surfer techniques, [Method] Taking the way to depict many kinds of choloplethic map through VB and Surfer techniques as an example, methods to realize data process, system protection and programming through ActiveX control under VB 6. 0 programming environment. [ Result] In the development of "Hunan Modern Agricultural Meteorological Business Service Comprehensive Platform" , because of different requirements, the workload was large, but picture and data was isolated by dint of ActiveX control, which improved the software efficiency. [Conclusion] The study solved the problems such as programming workload reduction, code utilization efficiency improvement and software interface.
