  In MFC application (Dialog based or Cform view), if i load bitmap image in the background, its taking more memory.. here is my coding..
  
  void CDlg_Splash::OnPaint()
  {
  CPaintDC dc(this); // device context for painting
  
  HBITMAP m_Bmap;
  CRect rect;
  HDC memdc;
  
  CString m_ifilename1;
  
  m_ifilename1 = "C:\\test.bmp";
  
  GetClientRect(&rect);
  
  m_Bmap=(HBITMAP)::LoadImage(NULL,m_ifilename1,IMAGE_BITMAP,0,0,LR_LOADFROMFILE);
  memdc=::CreateCompatibleDC(dc.m_hDC);
  ::SelectObject(memdc,m_Bmap);
  
  BitBlt(dc.m_hDC,0,0,rect.right,rect.bottom,memdc,0,0,SRCCOPY);
  DeleteObject(m_Bmap);
  DeleteObject(memdc);
  }
  
  is it correct ? and also let me know is there any memory leakage?
  is it possible to load jpeg image in MFC dialog? (to avoid more memory usage)
  
  Thanks in Advance...
