VB6中的DoEvents [英] DoEvents in VB6

问题描述

我的程序通过MSComm1将命令发送到相当慢的硬件.它使用Do循环中的DoEvents等待在Wait/Pause类型的子项中的答复，当MSComm1返回了预期数量的字符时退出.一切正常，但在Core2 Duo笔记本电脑上占用大约50％的CPU时间，在Celeron PC上占用98％的CPU时间.有更好的方法吗?

My program sends a command via MSComm1 to a fairly slow piece of hardware. It waits for a reply in a Wait/Pause type sub using DoEvents in a Do Loop, exiting when an expected number of characters have been returned by MSComm1. It all works fine but takes up about 50% of CPU time on a Core2 Duo laptop and 98% on a Celeron PC. Is there a better way?
