I have a simple code used in printing bmp in my app.:
OnPrint(CDC* pDC, CPrintInfo* pInfo)
{
      CBitmap bitmap;
      CDC memdc;
      bitmap.LoadBitmap("barcd.bmp");
      memdc.CreateCompatibleDC(pDC);
      pDC->BitBlt(0, 0, 100, 100, &memdc, 0, 0, SRCCOPY);
}
This code won't print the bmp "barcd.bmp". pls. help me work out this proble....or can you modify this simple code to work.... thanks

You have to add:
Memdc.SelectObject(&bitmap);

before the BitBlt.

You're proposed code seems as follows:
void OnPrint(CDC* pDC, CPrintInfo* pInfo)
{
      CBitmap (bitmap);
      CDC memdc;
      bitmap.LoadBitmap("barcd.bmp");
      memdc.CreateCompatibleDC(pDC);
      memdc.SelectObject(&bitmap);
      pDC->BitBlt(0, 0,100,100, &memdc, 0, 0, SRCCOPY);
}

but i'm afraid, the same problem occured......
the barcd.bmp exists in the proj directory to be sure...............

well I would atleast change

pDC->BitBlt( 0, 0, 100, 100, &memdc, 0, 0, SRCCOPY );

to

pDC->BitBlt( 0, 0, bitmap.Width(), bitmap.Height(), &memdc, 0, 0, SRCCOPY );

ALSO,

The "barcd.bmp" must be a RESOURCE withing the EXECUTABLE file, not a separate file within the (current) working directory! Thus, you will need to add the bitmap to the project as a RESOURCE, name it (you could keep 'barcd.bmp') and then call your code. If I am understanding your problem correctly, this should work!

Let us say you are going to load the bitmap file and not the resource.
Add this code
              HBITMAP m_hBitmap;
      m_hBitmap=(HBITMAP)::LoadImage(
            NULL,"barcd.bmp",IMAGE_BITMAP,
            0,0,LR_LOADFROMFILE|LR_DEFAULTSIZE);
      CBitmap *mbmp=CBitmap::FromHandle(m_hBitmap);
              CDC *memDC=new CDC;
      memDC->CreateCompatibleDC(pDC);
      memDC->SelectObject(mbmp);
              pDC->BitBlt(10,10,500,500,memDC,0,0,SRCCOPY);
              delete memDC;
