Download and upload file without storing to PC

Hi,
I have to Upload and download image to server

////////////////////////////For UPLOADING
file//////////////////////////////////////////////////////////////////////////////////////////////////////
CString sFName;
CDC ScreenDC;
ScreenDC.Attach(::GetDC(NULL));

CBitmap Capture;
CSize Dimensions(GetSystemMetrics(SM_CXSCREEN), GetSystemMetrics
(SM_CYSCREEN));
Capture.CreateCompatibleBitmap(&ScreenDC, Dimensions.cx,
Dimensions.cy);

CDC MemDC;
MemDC.CreateCompatibleDC(&ScreenDC);

CBitmap *OldBitmap = MemDC.SelectObject(&Capture);

MemDC.BitBlt(0, 0, Dimensions.cx, Dimensions.cy, &ScreenDC, 0, 0,
SRCCOPY);
CImage m2;
m2.Attach(Capture);
//m2.Save(fd.GetPathName());
m2.Save(_T("Image1.jpg"),Gdiplus::ImageFormatJPEG);//ImageFormatJPEG
m2.Detach();
MemDC.SelectObject(Capture);
Capture.Detach();
Is it possible to to MemDC to byte so that its directly uploaded to
server without storage in disk

CFile::modeWrite|CFile::typeBinary );
        int numBytes;
          char httpBuff[10000];

        try
        {
          while (numBytes = pFile->Read(httpBuff, 10000))
        {
            localFile->Write(httpBuff, numBytes);
