关于DXINPUT的鼠标编程问题

winchestrele

最近一直在学习DirectX9 User Interfaces Design and Implementation 这本书，看到鼠标编程那一块，有点不明白，我按着书上的代码做了一遍，发现运行程序时鼠标不见了，我把SetCooperativeLevel(hwnd,DISCL_FOREGROUND);独占模式去掉可以显示鼠标，但是还是看不到自己载入的光标图案，我在网上也搜索了很久，还是找不到解决方法，求哪位大神帮帮忙，下面是我的源码，两个函数，一个是初始化，一个是消息处理
bool Init_Dinpute(HINSTANCE hInst)
{
//载入自定义光标
D3DXGetImageInfoFromFile("../image/111.bmp",&Info);
        Device->CreateOffscreenPlainSurface(Info.Width,Info.Height,D3DFMT_A8R8G8B8,
                D3DPOOL_SYSTEMMEM,&g_MouseCursor,NULL);
        if(g_MouseCursor==NULL)
                MessageBox(NULL,"g_MouseCursor is empty","error",NULL);
        D3DXLoadSurfaceFromFile(g_MouseCursor,NULL,NULL,"../image/111.bmp",NULL,D3DX_FILTER_NONE,0xFF000000,NULL);

        DirectInput8Create(hInst, DIRECTINPUT_VERSION,IID_IDirectInput8, (void**)&g_lpDI, NULL);
        if(g_lpDI!=NULL)
        {
               


                g_lpDI->CreateDevice(GUID_SysMouse, &g_Mouse, NULL);//创建鼠标
                g_Mouse->SetCooperativeLevel(hwnd,DISCL_NONEXCLUSIVE|DISCL_FOREGROUND);//设置协作模式
                g_Mouse->SetDataFormat(&c_dfDIMouse );//设置数据格式
                hMouseEvent = CreateEvent(NULL, FALSE, FALSE, NULL);
                if(!hMouseEvent)
                        MessageBoxA(NULL,"hMouseEvent is NULL","",NULL);
            g_Mouse->SetEventNotification(hMouseEvent);
                DIPROPDWORD     property;
                property.diph.dwSize = sizeof(DIPROPDWORD);
                property.diph.dwHeaderSize = sizeof(DIPROPHEADER);
                property.diph.dwObj = 0;
                property.diph.dwHow = DIPH_DEVICE;
                property.dwData = 16;
        g_Mouse->SetProperty(DIPROP_BUFFERSIZE, &property.diph);
               
                Device->SetCursorProperties(0,0,g_MouseCursor);//设置光标
                Device->SetCursorPosition(0,0,D3DCURSOR_IMMEDIATE_UPDATE);
                Device->ShowCursor(true);
                return true;
        }
        return false;
}

void UpdateInpute()
{
       
        if(SUCCEEDED(g_Mouse->Acquire()))//获得鼠标设备
        {
                DIMOUSESTATE State;
                g_Mouse->GetDeviceState(sizeof(State),(LPVOID)&State);
                g_MouseX += State.lX;
                g_MouseY += State.lY;
                Device->SetCursorPosition(g_MouseX,g_MouseY,D3DCURSOR_IMMEDIATE_UPDATE);
                if(KEYDOWN(State.rgbButtons,1))
                        MessageBox(hwnd,"You pressed the right button","",MB_OK);
                if(KEYDOWN(State.rgbButtons,0))
                        MessageBox(hwnd,"You pressed the left button","",MB_OK);
        }
        g_Mouse->Unacquire();
       
}
