如何使用全局键盘挂钩发送键? [英] How do i send keys using a global keyboard hook?

问题描述

我正在尝试将密钥发送到一个应用程序，该应用程序不响应我到目前为止使用的任何API(SendInput()，PostMessage()，SendMessage()等).但是，我测试了Windows的屏幕键盘实用程序"，然后按了所需的键，应用程序很容易收到了这些键.

I'm trying to send keys to an application which does not respond to any of the API's that I have so far used (SendInput(), PostMessage(), SendMessage() and others). However, i tested Windows' On-Screen Keyboard Utility and pressed the keys i needed and the application received these keys easily.

如果我正确理解键盘实用程序使用全局键盘钩子来发送键的话，那么我很感兴趣如何实现这一点.我曾尝试找到如何在Google上完成此操作的示例，但没有结果.

If i understand correctly the keyboard utility uses global keyboard hooks to send the keys, so I'm interested i how i could do so as well. I have tried finding examples of how this can be done on google but have come up with no results.

谢谢.

推荐答案

我解决了.我正在将密钥发送到DirectX应用程序.原来我不得不发送DirectX扫描代码，而不是常规的VK_KEY.

I solved it. I was sending keys to a DirectX application. Turns out i had to send DirectX scan codes instead of regular VK_KEY's.

可以在以下位置找到扫描代码列表: http://www.gamespp.com/directx/directInputKeyboardScanCodes.html

A list of scan codes can be found at: http://www.gamespp.com/directx/directInputKeyboardScanCodes.html

将它们与SendInput()结合使用，一切都很好.

Using these with SendInput() and everything worked great.

也感谢您的帮助.

干杯.
