MFC定时器 [英] MFC TIMER

问题描述

如果多次调用SetTimer会发生什么。任何资源泄漏？ 

What will happen if SetTimer is called multiple times. Any resource leak? 

    id = SetTimer（1,250，NULL）;

   id = SetTimer(1, 250, NULL);

    id = SetTimer（1,250，NULL）;

   id = SetTimer(1, 250, NULL);

推荐答案

由于CWnd :: SetTimer最终调用
SetTimer ，然后将适用该文档。

Since CWnd::SetTimer ends up calling SetTimer, then the documentation for that would apply.

正如它所述，如果您使用相同的事件ID，那么它只是用旧的计时器替换旧计时器并重置计时器。

As it states, if you use the same event id, then it just replaces the old timer with a new one and resets the timer.
