只需使用SetTimer方法，并传递两个参数:计时器ID(任意数字)和超时(以毫秒为单位).然后编写OnTimer实现，并在BEGIN_MESSAGE_MAP...END_MESSAGE_MAP内写一个条目ON_WM_TIMER.

Just use SetTimer method, and pass two arguments: Timer ID (any number), and the timeout in milliseconds. Then write up OnTimer implementation, and an entry ON_WM_TIMER inside BEGIN_MESSAGE_MAP...END_MESSAGE_MAP.
