MFC dialog Box Dialog response keyboard events

1. OnKeyDown, No.

The dialog program originally did not respond directly to keyboard events, and if you use onkeydown you will find that it does not work.
So you want to press "left button", "W Key", "9 keyboard" should be how to respond?
the bool PreTranslateMessage (msg* PMSG) function of the overloaded base class
