基于PowerBuilder的一种优化Data Window研究与实践

Research and development for optimal data window based on powerbuilder

数据窗口(DataWindow)是PowerBuilder的技术核心,也可以说成是它的一项专利。如何充分发掘数据窗口的技术优势是用好PowerBuilder的关键。本文基于PowerBuilder提供的Modify函数就如何解决在一个数据窗口中进行多表更新和数据窗口的精确页面打印作了一定的研究和分析,并给出了具体的使用方法和应用实例。

Data Window is not only the kernel technology of Power Builder, and also is a patent of it. How enough to find technical quality of Data Window is the key to Power Builder. On the basis of the Modify function provided by Power Builder, this paper has researched and analysed how to solve the updating multiple tables in one DataWindow, print the exactitude page of DataWindow, at last give the exactively method of use and example of applications.
