如何模拟多媒体键preSS（C语言）？ [英] How to simulate multimedia key press (in C)?

问题描述

现代的键盘有特殊的多媒体键，如暂停/播放或打开Web浏览器。是否可以编写一个程序，presses这些钥匙？

Modern keyboards have special multimedia keys, e.g. 'Pause/Play' or 'Open Web Browser'. Is it possible to write a program that "presses" these keys?

我想美元P c ^ $ PFER解决办法，但我会接受的语言无关的解决方案了。

I would prefer solution in C, but I would accept a language agnostic solution, too.

推荐答案

使用的SendInput的Windows API，如果你谈论的是在Win32下编程。

Use the SendInput Windows API, if you are talking about programming under Win32.

您需要建立输入结构，设置型部件INPUT_KEYBOARD。在文员（KEYBDINPUT型），可以设置VK（虚拟键）到您想要的VK code（例如，VK_MEDIA_NEXT_TRACK，VK_MEDIA_STOP）。

You need to build INPUT structures, setting the type member to INPUT_KEYBOARD. In the ki member (KEYBDINPUT type), you can set vk (virtual key) to your desired VK code (for example, VK_MEDIA_NEXT_TRACK, VK_MEDIA_STOP).

我没有测试以下，但应该是这样的：

I've not tested the following, but should be like this:

KEYBDINPUT kbi;
kbi.wVk = VK_MEDIA_STOP; // Provide your own
kbi.wScan = 0;
kbi.dwFlags = 0;  // See docs for flags (mm keys may need Extended key flag)
kbi.time = 0;
kbi.dwExtraInfo = (ULONG_PTR) GetMessageExtraInfo();

INPUT input;
input.type = INPUT_KEYBOARD;
input.ki   = kbi;

SendInput(1, &input, sizeof(INPUT));
