原始输入是替代键盘挂钩吗？

简单的问题——

我正在阅读有关键盘挂钩的内容，有人建议使用原始输入来执行此操作，但我还没有找到任何示例。例如，我在

RAWINPUTDEVICE rid[1];
rid[0].usUsagePage = 0x01;
rid[0].usUsage = 0x06;
rid[0].hwndTarget = hWnd;
rid[0].dwFlags = 0;
RegisterRawInputDevices(rid, 1, sizeof(rid[0]));

应用程序自己的窗口中使用 And catchsign WM_INPUT 很好，但不在应用程序之外。这可以在应用程序之外实现吗？还是必须使用 WH_KEYBOARD 或 WH_KEYBOARD_LL？ MSDN 没有明确说明原始输入是否可以在全球范围内进行。

编辑：我了解 Hooks，但我想知道你是否也可以使用原始输入来做到这一点！

干杯

Quick question --

I was reading about keyboard hooks and one suggested using Raw Input to do this, yet I havn't found any example of it.
For example I am using

RAWINPUTDEVICE rid[1];
rid[0].usUsagePage = 0x01;
rid[0].usUsage = 0x06;
rid[0].hwndTarget = hWnd;
rid[0].dwFlags = 0;
RegisterRawInputDevices(rid, 1, sizeof(rid[0]));

And catchign WM_INPUT fine in the applications own window, but not outside the application. Is this possible outside the application or do you have to use WH_KEYBOARD or WH_KEYBOARD_LL? MSDN didn't make it clear if Raw Input could be made globally.

EDIT: I know about Hooks but I want to know if you can do it with Raw input too!

Cheers

查看该内容的 MSDN 文档，有一个名为 < code>RIDEV_INPUTSINK 描述为：“如果设置，即使调用者不在前台，也可以使调用者接收输入。”

我自己并没有搞乱这一点，但听起来它对于从应用程序窗口之外获取输入可能很有用。

这就是我初始化 RAW INPUT 以全局拦截鼠标和键盘事件的方式。与钩子相比，最大的优点是不需要 DLL。
您可以使用 WM_INPUT 处理窗口过程中的原始输入事件。有关详细信息：原始输入< /a>

#include <Windows.h>

const USHORT HID_MOUSE    = 2;
const USHORT HID_KEYBOARD = 6;

bool HID_RegisterDevice(HWND hTarget, USHORT usage)
{
    RAWINPUTDEVICE hid;
    hid.usUsagePage = 1;
    hid.usUsage = usage;
    hid.dwFlags = RIDEV_DEVNOTIFY | RIDEV_INPUTSINK;
    hid.hwndTarget = hTarget;

    return !!RegisterRawInputDevices(&hid, 1, sizeof(RAWINPUTDEVICE));
}

void HID_UnregisterDevice(USHORT usage)
{
    RAWINPUTDEVICE hid;
    hid.usUsagePage = 1;
    hid.usUsage = usage;
    hid.dwFlags = RIDEV_REMOVE;
    hid.hwndTarget = NULL;

    RegisterRawInputDevices(&hid, 1, sizeof(RAWINPUTDEVICE));
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE, LPSTR cmd_line, int cmd_show)
{
    WNDCLASS wc;
    ...
    RegisterClass(&wc);

    HWND hwnd = CreateWindow(...);
    ...

    HID_RegisterDevice(hwnd, HID_KEYBOARD);
    HID_RegisterDevice(hwnd, HID_MOUSE);

    MSG msg;
    while(GetMessage(&msg, NULL, 0, 0))
    {
        ...
    }

    HID_UnregisterDevice(HID_MOUSE);
    HID_UnregisterDevice(HID_KEYBOARD);

    return (int) msg.wParam;
}

This is how I initialize RAW INPUT to globally intercept mouse and keyboard events. The great advantage compared to hooks is you don't need a DLL.
You treats the raw input events in the window procedure with WM_INPUT. For further informations : RAW INPUT

#include <Windows.h>

const USHORT HID_MOUSE    = 2;
const USHORT HID_KEYBOARD = 6;

bool HID_RegisterDevice(HWND hTarget, USHORT usage)
{
    RAWINPUTDEVICE hid;
    hid.usUsagePage = 1;
    hid.usUsage = usage;
    hid.dwFlags = RIDEV_DEVNOTIFY | RIDEV_INPUTSINK;
    hid.hwndTarget = hTarget;

    return !!RegisterRawInputDevices(&hid, 1, sizeof(RAWINPUTDEVICE));
}

void HID_UnregisterDevice(USHORT usage)
{
    RAWINPUTDEVICE hid;
    hid.usUsagePage = 1;
    hid.usUsage = usage;
    hid.dwFlags = RIDEV_REMOVE;
    hid.hwndTarget = NULL;

    RegisterRawInputDevices(&hid, 1, sizeof(RAWINPUTDEVICE));
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE, LPSTR cmd_line, int cmd_show)
{
    WNDCLASS wc;
    ...
    RegisterClass(&wc);

    HWND hwnd = CreateWindow(...);
    ...

    HID_RegisterDevice(hwnd, HID_KEYBOARD);
    HID_RegisterDevice(hwnd, HID_MOUSE);

    MSG msg;
    while(GetMessage(&msg, NULL, 0, 0))
    {
        ...
    }

    HID_UnregisterDevice(HID_MOUSE);
    HID_UnregisterDevice(HID_KEYBOARD);

    return (int) msg.wParam;
}
