只需使用 SetTimer
方法,并传递两个参数:Timer ID(任意数字)和超时时间(以毫秒为单位).然后编写 OnTimer
实现,以及 BEGIN_MESSAGE_MAP...END_MESSAGE_MAP
中的条目 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
.
CWnd::SetTimer需要 3 个参数,但只需要 2 个.将第三个参数作为 NULL 传递.
CWnd::SetTimer takes 3 parameters, but only 2 are required. Pass third argument as NULL.
CWnd::OnTimer
