CPaintDC dc(this); // device context for painting

// TODO: Add your message handler code here

CBitmap BmpLady;

CDC MemDCLady;

// Load the bitmap from the resource

BmpLady.LoadBitmap(IDB_LADY);

// Create a memory device compatible with the above CPaintDC variable

MemDCLady.CreateCompatibleDC(&dc);

// Select the new bitmap

CBitmap *BmpPrevious = MemDCLady.SelectObject(&BmpLady);

// Copy the bits from the memory DC into the current dc

dc.BitBlt(20, 10, 436, 364, &MemDCLady, 0, 0, SRCCOPY);

// Restore the old bitmap

dc.SelectObject(BmpPrevious);

// Do not call CView::OnPaint() for painting messages
