Send keys without SendMessage and PostMessage

问题:

Is it possible to send keys to a program without SendMessage and PostMessage API?

回答1:

The official way to fake input does not involve sending or posting Windows messages directly. Instead you are meant to call SendInput.

When you use SendInput it is indistinguishable from actually pressing the real keys. When you call SendInput to fake keyboard input, the system ultimately posts messages to the message queue of the foreground thread that created the window with the keyboard focus.
