利用directinput 模拟鼠标移动 帮我写个dll别的程序可以调用

以下是一个简单的示例代码，它使用DirectInput模拟鼠标移动。您可以将此代码编译为DLL，并将其与其他程序一起使用。

#define DIRECTINPUT_VERSION 0x0800
#include <dinput.h>

#pragma comment(lib, "dinput8.lib")
#pragma comment(lib, "dxguid.lib")

LPDIRECTINPUT8 g_pDI = NULL;
LPDIRECTINPUTDEVICE8 g_pMouse = NULL;

BOOL APIENTRY DllMain(HMODULE hModule, DWORD  ul_reason_for_call, LPVOID lpReserved)
{
    switch (ul_reason_for_call)
    {
    case DLL_PROCESS_ATTACH:
        // 初始化DirectInput
        DirectInput8Create(GetModuleHandle(NULL), DIRECTINPUT_VERSION, IID_IDirectInput8, (void**)&g_pDI, NULL);

        // 创建鼠标设备
        g_pDI->CreateDevice(GUID_SysMouse, &g_pMouse, NULL);

        // 设置鼠标数据格式
        g_pMouse->SetDataFormat(&c_dfDIMouse);

        // 设置鼠标协作级别
        g_pMouse->SetCooperativeLevel(NULL, DISCL_BACKGROUND | DISCL_NONEXCLUSIVE);

        // 设置鼠标缓冲区大小
        DIPROPDWORD dipdw;
        dipdw.diph.dwSize = sizeof(DIPROPDWORD);
        dipdw.diph.dwHeaderSize = sizeof(DIPROPHEADER);
        dipdw.diph.dwObj = 0;
        dipdw.diph.dwHow = DIPH_DEVICE;
        dipdw.dwData = 16;
        g_pMouse->SetProperty(DIPROP_BUFFERSIZE, &dipdw.diph);

        // 启动鼠标设备
        g_pMouse->Acquire();
        break;

    case DLL_PROCESS_DETACH:
        // 释放鼠标设备
        if (g_pMouse)
        {
            g_pMouse->Unacquire();
            g_pMouse->Release();
            g_pMouse = NULL;
        }

        // 释放DirectInput
        if (g_pDI)
        {
            g_pDI->Release();
            g_pDI = NULL;
        }
        break;
    }

    return TRUE;
}

// 模拟鼠标移动
void MoveMouse(int deltaX, int deltaY)
{
    DIMOUSESTATE2 dims;
    memset(&dims, 0, sizeof(dims));
    dims.lX = deltaX;
    dims.lY = deltaY;

    g_pMouse->SetDataFormat(&c_dfDIMouse);
    g_pMouse->Acquire();
    g_pMouse->GetDeviceState(sizeof(DIMOUSESTATE2), &dims);
    g_pMouse->Unacquire();
}
