如何通过套接字发送gdi plus数据？

问：

我正在构建一个远程帮助软件，例如团队查看器，我需要在我的服务器上接收客户端的屏幕。 我用来获取丝网打印并将其保存到：gdi plusjpeg

    int GetEncoderClsid(const WCHAR* format, CLSID* pClsid) {
        using namespace Gdiplus;
        UINT  num = 0;
        UINT  size = 0;
    
        ImageCodecInfo* pImageCodecInfo = NULL;
    
        GetImageEncodersSize(&num, &size);
        if(size == 0)
            return -1;
    
        pImageCodecInfo = (ImageCodecInfo*)(malloc(size));
        if(pImageCodecInfo == NULL)
            return -1;
    
        GetImageEncoders(num, size, pImageCodecInfo);
        for(UINT j = 0; j < num; ++j)
        {
            if( wcscmp(pImageCodecInfo[j].MimeType, format) == 0 )
            {
                *pClsid = pImageCodecInfo[j].Clsid;
                free(pImageCodecInfo);
                return j;
            }
        }
        free(pImageCodecInfo);
        return 0;
    }
    
    class frame_catcher
    {
    public:
       int frame_catcher_func(){
    
        using namespace Gdiplus;
        IStream* istream;
        HRESULT res = CreateStreamOnHGlobal(NULL, true, &istream);
        GdiplusStartupInput gdiplusStartupInput;
        ULONG_PTR gdiplusToken;
        GdiplusStartup(&gdiplusToken, &gdiplusStartupInput, NULL);
        {
            HDC scrdc, memdc;
            HBITMAP membit;
            scrdc = ::GetDC(0);
            int Height = GetSystemMetrics(SM_CYSCREEN);
            int Width = GetSystemMetrics(SM_CXSCREEN);
            memdc = CreateCompatibleDC(scrdc);
            membit = CreateCompatibleBitmap(scrdc, Width, Height);
            HBITMAP hOldBitmap =(HBITMAP) SelectObject(memdc, membit);
            BitBlt(memdc, 0, 0, Width, Height, scrdc, 0, 0, SRCCOPY);
    
            Gdiplus::Bitmap bitmap(membit, NULL);
            CLSID clsid;
            GetEncoderClsid(L"image/jpeg", &clsid); 
            bitmap.Save(L"print.jpeg", &clsid, NULL); 
            bitmap.Save(istream, &clsid, NULL);
    
            delete &clsid;
            DeleteObject(memdc);
            DeleteObject(membit);
            ::ReleaseDC(0,scrdc);
        }
        GdiplusShutdown(gdiplusToken);
        istream->Release();
        return 0;
    std::cout << "Print done" << std::endl;
    }
};

我可以在代码中从哪里获得，idk，图像的“”，将其放入 a 并通过 发送？ 顺便说一句，我是新手 - 对不起糟糕的编程 - 但我需要继续这样做;我正在制作我的毕业作品，无法改变它。谢谢大家。binariesstd::stringsocketc++
