推荐答案

这是一个问题吗?只需在此方法中设置一个断点，您将看到按热键并相应地使用其他消息参数会发生什么.邮件结构记录在这里: http://msdn.microsoft.com/zh-cn/library/ms646279(v = vs.85).aspx [

Is it a problem at all or not? Simply put a break point in this method and you will see what happens if you press a hot key, use other message parameters accordingly. The message structure is documented here: http://msdn.microsoft.com/en-us/library/ms646279(v=vs.85).aspx[^].
