汇编教程：启动画面

核心提示：在这个例子中我们要使用第一种方法.当你设定的时间到了, 与定时器相连的窗口会收到 WM_TIMER 消息.例如,你指定 uElapse 的值为 1000, 你的窗口每过一秒都会收到 WM_TIMER 消息.等到你再也不需要这个定时器了,就用 KillTimer 来去除定时器.KillTimer proto hWnd:D

在这个例子中我们要使用第一种方法.

当你设定的时间到了, 与定时器相连的窗口会收到 WM_TIMER 消息.例如,你指定 uElapse 的值为 1000, 你的窗口每过一秒都会收到 WM_TIMER 消息.

等到你再也不需要这个定时器了,就用 KillTimer 来去除定时器.

KillTimer proto hWnd:DWORD, TimerID:DWORD
