如何仅将击键发送到一个程序？
我一直很难找到任何有用的东西，但我发现有人问如何做到这一点，（如何将击键发送到窗口？）
如果使用代码，我可以设置记事本的文本，但我想发送按键但设置文本，我 想要发送像 keybd_event 这样的密钥，我一直在使用它，但我只想将它发送到一个程序。
keybd_event('a', NULL, NULL, NULL);
keybd_event('a', NULL, KEYEVENTF_KEYUP, NULL);
我怎么能那样做呢？

听起来您正试图在发送密钥之前使窗口获得焦点。查看
FindWindow和SetForegroundWindow。像这样的东西应该有效：
如果您正在谈论直接更改窗口的文本，请查看
GetWindow导航窗口树和SendMessage带有WM_SETTEXT参数。Sounds like you're trying to make a window have the focus before sending your keys. Look at
FindWindowandSetForegroundWindow.Something like this should work:
If instead you're talking about changing a window's text directly, look at
GetWindowto navigate the window tree andSendMessagewith aWM_SETTEXTparameter.
