Win32环境下取消大数据量处理过程的方法研究

大数据量处理过程是应用程序开发中的常见问题，为了提高应用程序的交互性，取消处理过程的操作通常是必要的。消息队列是Ｗｉｎｄｏｗｓ的核心问题之一，在消息被处理之前，通过对消息队列的检索，可以完成消息响应过程的重定向；线程是Ｗｉｎ３２环境下操作系统级上的、区别于１６位Ｗｉｎｄｏｗｓ的全新概念，线程概念的出现在一定程度上使得编制Ｗｉｎ３２环境下的应用程序具有了更大的灵活性。本文提出两种分别基于检索消息队列和线程的方法用于Ｗｉｎ３２环境下实现大数据处理过程中的取消操作，均取得了令人满意的效果。

On Method for Canceling Mass Data Processing in Win32

The mass data processing is a common problem during the development of application, and to make application user friendly better, it usually provides the means to escape from mass data processing. Message array is one of core technology in Windows, before message being processed, application can redirect the message process by examining message array. Thread is new and operating-system-level concept in Win32, and it does not exist in 16-bits Windows environment. Thread brings some flexibility to the development of application. Two methods for canceling mass data processing which are based on message array and thread in Win32 respectively, presented in this paper, and the results of two methods are satisfied.
