推荐答案

看看 ^ ]或 GetKeyState [^ ]

该组合永远不会存储在您的MSG结构中.因此，如果以上内容不适合您，您将不得不查找两条消息，一条消息传递给A，一条消息传递给1.

Have a look at GetAsyncKeyState[^] or GetKeyState[^]

The combination is never stored in your MSG struct. So if the above doesn''t cut it for you, you will have to look for two messages, one for A and one for 1.
