摘要
针对通用电子装备仿真系统的高效性要求,分析了当前基于Windows操作系统程序的消息循环机制及使用MFC开发的应用程序执行效率不高的主要原因.通过重载IsIdleMessage函数和直接发送WM_KICKIDLE消息,优化了操作系统内部对闲置处理的控制,避免了系统因频繁执行闲置处理而造成消息阻塞,降低了系统资源的占用,提高了通用电子装备仿真系统的运行效率.
The paper analyses mechanism of message loop based on the Windows operation system and the reasons of low efficiency in execution of a program which is developed by using MFC. By overlapping the function of IsIdleMessage and posting the message of WM_KICKDLE to optimize the controlling of management in idle time, avoided the message blocking, decreased the occupation of system resource, and increased the efficiency in execution of the simulation system.
