Abstract: Aimed at the condition that it is difficult to develop monitoring applications based on databases using PowerBuilder because of its insufficient support for multithread applications, this paper introduces a method implementing concurrent processing using the timer, which makes it rather simple to achieve concurrency requirement of monitoring applications.

摘要： 针对ＰｏｗｅｒＢｕｉｌｄｅｒ缺乏对多线程应用程序的支持且开发基于数据库的监控程序比较困难的情况，提出了一种用定时器实现并发处理的方法，以比较简单的方式实现了监控程序的并发性要求。
