如何在Windows 7下拦截Windows密钥？

您好，

我已经实现了一个低级键盘挂钩，如此处。这在WinXP下工作得很好。问题是，在 Windows 7 下，左右 Windows 键不再被拦截。

任何有关如何在 Windows 7 下重新捕获这些密钥的建议，我们将不胜感激！

干杯，

罗尼

我构建了一个库，因为在很多情况下正常的挂钩对我来说不起作用，所以我构建了 ac 库来与底层的过滤器驱动程序进行通信，以完成设备输入拦截的工作。以下是如何使用此库捕获 Windows 密钥的示例：

#include <iostream>
#include <interception.h>
#include "utils.h" // for process priority control

const InterceptionKeyStroke windows_key_down = {91, INTERCEPTION_KEY_E0 | INTERCEPTION_KEY_DOWN};
const InterceptionKeyStroke windows_key_up = {91, INTERCEPTION_KEY_E0 | INTERCEPTION_KEY_UP};

bool operator == (const InterceptionKeyStroke &left, const InterceptionKeyStroke &right)
{
    return left.code == right.code && left.state == right.state;
}

int main()
{
    using namespace std;

    InterceptionContext context;
    InterceptionDevice device;
    InterceptionStroke stroke;

    raise_process_priority();

    context = interception_create_context();

    interception_set_filter(context, interception_is_keyboard, INTERCEPTION_FILTER_KEY_ALL);

    while(interception_receive(context, device = interception_wait(context), &stroke, 1) > 0)
    {
        InterceptionKeyStroke &keystroke = *(InterceptionKeyStroke *) &stroke;

        if(keystroke == windows_key_down)
            cout << "Windows Key Down" << endl;

        if(keystroke == windows_key_up)
            cout << "Windows Key Up" << endl;

        interception_send(context, device, &stroke, 1);
    }

    interception_destroy_context(context);

    return 0;
}

该示例捕获密钥并将其发送回操作系统，但您也可以执行其他操作。

I have built a library because normal hooking was not working for me in a number of cases, so I've built a c library to communicate with filter drivers under the hood to do the work of device input interception. Here's a sample of how to capture the Windows key using this library:

#include <iostream>
#include <interception.h>
#include "utils.h" // for process priority control

const InterceptionKeyStroke windows_key_down = {91, INTERCEPTION_KEY_E0 | INTERCEPTION_KEY_DOWN};
const InterceptionKeyStroke windows_key_up = {91, INTERCEPTION_KEY_E0 | INTERCEPTION_KEY_UP};

bool operator == (const InterceptionKeyStroke &left, const InterceptionKeyStroke &right)
{
    return left.code == right.code && left.state == right.state;
}

int main()
{
    using namespace std;

    InterceptionContext context;
    InterceptionDevice device;
    InterceptionStroke stroke;

    raise_process_priority();

    context = interception_create_context();

    interception_set_filter(context, interception_is_keyboard, INTERCEPTION_FILTER_KEY_ALL);

    while(interception_receive(context, device = interception_wait(context), &stroke, 1) > 0)
    {
        InterceptionKeyStroke &keystroke = *(InterceptionKeyStroke *) &stroke;

        if(keystroke == windows_key_down)
            cout << "Windows Key Down" << endl;

        if(keystroke == windows_key_up)
            cout << "Windows Key Up" << endl;

        interception_send(context, device, &stroke, 1);
    }

    interception_destroy_context(context);

    return 0;
}

The sample captures the key and send it back to the operating system, but you can do other things instead.
