我想做一个虚拟键盘.是否需要将WM_KEYDOWN发送到当前活动窗口或HWND_BROADCAST? [英] I want to make a virtual keyboard. Do I need to send WM_KEYDOWN to the current active window or HWND_BROADCAST?

问题描述

我正在制作一个模拟键盘的应用程序. 我将通过将WM_KEYDOWN发送到窗口来完成此操作，但是我不确定将消息发送到何处. 到当前活动的窗口还是HWND_BROADCAST?

I am making an app that simulates a keyboard. I will do it by sending WM_KEYDOWN to a window, but I am not sure where to send the message. to the currently active window or to HWND_BROADCAST?

这是我发布的另一个与此问题相关的问题.
如果我发送WM_KEYDOWN消息(使用wndproc)，计算机会一直按住该键，直到我发送WM_KEYUP吗?

Here is an other question I posted, related to this one.
If I send a WM_KEYDOWN message (using wndproc) will the computer hold the key down until I send WM_KEYUP?

推荐答案

如果制作通用虚拟键盘而不必担心哪个窗口处于活动状态(这是窗口管理器的职责)，则可以使用SendInput:

If make a generic virtual keyboard and not worry about which window is active (which is the window manager's business), you can use SendInput: http://msdn.microsoft.com/en-us/library/ms646310(VS.85).aspx
