在PB数据窗口中实现数据的灵活编程

Implementation of Flexible Design Program in Datawindow of PB

PowerBuilder是Powersoft公司推出的基于客户机/服务器体系结构的强有力的数据库应用程序开发工具。为了在PowerBuilder中实现对数据窗口对象中的数据进行灵活编程处理,文中提出了三种不同的编程方案,分别是在PB提供的事件中编程方法、结合系统函数和数据窗口控件编程方法、采用自定义函数法结合数据窗口控件方法。结合一个工程实例,对三种方案各自的特点进行了分析和比较。在实际的应用过程中,结合不同的情况,灵活使用上述方法,可以提高编程效率和系统运行效率。

PowerBuilder is a powerful tool to exploit the database application based on C/S system.It is exploited by Powersoft corp..In order to achieve the flexible design program to the data in datawindow of PowerBuilder,three methods are presented in this paper .Firstly,can program in the event.Secondly,can use the function and datawindow object.Thirdly,can use the user-defined function and datawindow object.These methods are compared by examples.These methods can be used in deferent applications to improving the programming efficiency and the program running efficiency.
