在句柄内进行鼠标和键盘的操作 做个类和几个函数

在句柄内进行鼠标和键盘操作通常涉及Windows API编程，特别是在C++中。你可以创建一个类，比如`MouseKeyboardController`，包含一些成员函数来控制鼠标的移动、点击以及处理键盘输入。这里是一个简单的示例：

#include <windows.h>
#include <iostream>

class MouseKeyboardController {
private:
    HANDLE mouseHandle;
    HANDLE keyboardHandle;

public:
    MouseKeyboardController() {
        if (FAILED(DirectInput8Create(GetModuleHandle(NULL), DIRECTINPUT_VERSION, IID_IDirectInput8, (void**)&directInput, NULL))) {
            std::cerr << "Failed to create DirectInput object." << std::endl;
            return;
        }

        // 获取鼠标和键盘设备句柄
        if (FAILED(directInput->CreateDevice(GUID_SysKeyboard, &keyboardHandle, NULL))) {
            std::cerr << "Failed to create keyboard device." << std::endl;
            return;
        }
        if (FAILED(directInput->CreateDevice(GUID_SysMouse, &mouseHandle, NULL))) {
            std::cerr << "Failed to create mouse device." << std::endl;
            return;
        }
    }

    ~MouseKeyboardController() {
        // 在析构函数中关闭设备和释放资源
        if (mouseHandle != INVALID_HANDLE_VALUE) {
            ReleaseCapture();
            CloseHandle(mouseHandle);
        }
        if (keyboardHandle != INVALID_HANDLE_VALUE) {
            directInput->ReleaseDevice(keyboardHandle);
            CloseHandle(keyboardHandle);
        }
        directInput->Release();
    }

    void MoveMouse(int x, int y) {
        if (mouseHandle != INVALID_HANDLE_VALUE) {
            POINT pos = {x, y};
            SetCursorPos(pos.x, pos.y);
            if (GetAsyncKeyState(VK_LBUTTON)) {
                // 左键按下时需要模拟按住事件
                while (GetAsyncKeyState(VK_LBUTTON))
                    SendInput(1, (PINPUT)&keybd_event, sizeof(INPUT));
            }
        }
    }

    void ClickMouse(bool leftButton) {
        if (mouseHandle != INVALID_HANDLE_VALUE) {
            INPUT input;
            ZeroMemory(&input, sizeof(INPUT));

            input.type = INPUT_MOUSE;
            input.mi.dwFlags = MI_LEFTDOWN | (leftButton ? MI_LEFTUP : 0);
            input.mi.dx = 0;
            input.mi.dy = 0;
            input.mi.time = 0;
            SendInput(1, &input, sizeof(INPUT));
        }
    }

private:
    static const DWORD keybd_event = 0x01; // KEYEVENTF_SCANCODE bit mask for VK_*
};

// 使用示例
int main() {
    MouseKeyboardController controller;
    controller.MoveMouse(100, 200); // 移动鼠标到 (100, 200)
    controller.ClickMouse(true); // 左键单击
    return 0;
}

在这个例子中，我们首先创建了DirectInput对象，然后获取鼠标和键盘设备句柄。之后，我们定义了一些功能函数，如`MoveMouse`用于移动鼠标，`ClickMouse`用于模拟鼠标点击。注意，这个示例仅适用于Windows平台，并假设你已经包含了必要的头文件和链接了相关的库。
