如果我发送WM_KEYDOWN消息(使用wndproc)，计算机会一直按住该键，直到发送WM_KEYUP吗? [英] If I send a WM_KEYDOWN message (using wndproc) will the computer hold the key down until I send WM_KEYUP?

问题描述

我正在寻找一种解决方案，以编程方式在某个时间(不知道多少时间)内按下键盘键.

I am looking for a solution to programmatically hold a keyboard key down during some time (I don't know how many time).

我认为，如果我发送WM_KEYDOWN消息，则在发送WM_KEYUP之前，该密钥将一直处于按住状态，但是我不确定.

I think that if I send a WM_KEYDOWN message the key will be held down until WM_KEYUP is send, but I am not sure.

我会测试一下.但是我需要走了，我没有很多时间.我想看看是否有人已经对此进行了测试.

I would test it. But I need to go and I don't have much time. I want to see if someone already tested this.

这是我发布的另一个与此问题相关的问题.

Here is an other question I posted, related to this one.
I want to make a virtual keyboard. Do I need to send WM_KEYDOWN to the current active window or HWND_BROADCAST?

推荐答案

否，因为如果检查使用键盘时发送的消息，则会看到以下消息:

No, because If you examine the messages sent when using the keyboard, you'll see that the message are as follow:

WM_KEYDOWN
WM_KEYPRESS
WM_KEYUP

WM_KEYPRESS消息每隔两次滴答发送一次(取决于键盘配置).

The WM_KEYPRESS message is sent every couple of ticks (depending on the keyboard configuration).
