code for load Logo Image:
 
 
Bool :: OnInitDialog()
{
VERIFY(m_bmpLogo.LoadBitmap(IDB_LOGO));
 BITMAP bm;
 m_bmpLogo.GetBitmap(&bm);
 m_imgLogo.Create(NULL, WS_CHILD|WS_VISIBLE|SS_BITMAP|SS_CENTERIMAGE, CRect(0, 0, 0, bm.bmHeight), this); 
 if(!m_wndReBar.Create(this, 0)
   || !m_wndReBar.AddBar(&m_imgLogo, NULL, NULL, RBBS_NOGRIPPER | RBBS_FIXEDBMP | RBBS_FIXEDSIZE)) {
   return -1;
 }
 UpdateLogoImage();
}
 
/////////
void ::OnPaint()
{
 CPaintDC dc(this); 
 UpdateLogoImage();
}
////////
 
void ::UpdateLogoImage()
{
 RepositionBars( AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, 0 );
 if(m_imgLogo.GetSafeHwnd()) {
  RECT r;
  GetClientRect(&r);
  m_imgLogo.SetBitmap(NULL);
  BITMAP bmLogo;
  m_bmpLogo.GetBitmap(&bmLogo);
  int nWidth = r.right - r.left;
  int nHeight = bmLogo.bmHeight;
  CBitmap bmpNew;
  bmpNew.CreateCompatibleBitmap(GetDC(), nWidth, nHeight);
  CDC dcBmpSrc;
  if(dcBmpSrc.CreateCompatibleDC(NULL)) {
   dcBmpSrc.SelectObject(m_bmpLogo);
   CDC dcBmpNew;
   if(dcBmpNew.CreateCompatibleDC(NULL)) {
    dcBmpNew.SelectObject(bmpNew);
    BITMAP bmSrc;
    m_bmpLogo.GetBitmap(&bmSrc);
    dcBmpNew.FillRect(CRect(0, 0, nWidth, nHeight), &CBrush((COLORREF)0xffffff));
    dcBmpNew.BitBlt(nWidth - bmSrc.bmWidth, 0, bmSrc.bmWidth, bmSrc.bmHeight, &dcBmpSrc, 0, 0, SRCCOPY);
    dcBmpNew.DeleteDC();
    m_imgLogo.SetBitmap(bmpNew);    }
   dcBmpSrc.DeleteDC();
  }
 }
}

Hi,
You call GetDC but not ReleaseDC, you call GetDC in OnPaint handler.
 
Comment this call in OnPaint. better move it to OnSize. and dont' forget add ReleaseDC.

hi Oleg,

add ReleaseDC in OnPaint: but not display logo
 
void ::OnPaint()
{
 CPaintDC dc(this);
 HDC hdc=dc.GetSafeHdc();
 UpdateLogoImage();
 ::ReleaseDC(GetSafeHwnd(),hdc);
}
 
if I comment GetDC call in OnPaint is not display logo.
 
 
call UpdateLogoImage() int Onsize();
 
void ::OnSize(UINT nType, int cx, int cy)
{ 
 CXTPDialogBase<CXTResizeDialog>::OnSize(nType, cx, cy);
 UpdateLogoImage(); 
}

Hi;

as Oleg explained, you call GetDC() in UpdateLogoImage() but never call ReleaseDC():

void ::UpdateLogoImage()
{
 RepositionBars( AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, 0 );
 if(m_imgLogo.GetSafeHwnd()) {
  RECT r;
  GetClientRect(&r);
  m_imgLogo.SetBitmap(NULL);
  BITMAP bmLogo;
  m_bmpLogo.GetBitmap(&bmLogo);
  int nWidth = r.right - r.left;
  int nHeight = bmLogo.bmHeight;
  CBitmap bmpNew;
  bmpNew.CreateCompatibleBitmap(GetDC(), nWidth, nHeight);
  CDC dcBmpSrc;
  if(dcBmpSrc.CreateCompatibleDC(NULL)) {
   dcBmpSrc.SelectObject(m_bmpLogo);
   CDC dcBmpNew;
   if(dcBmpNew.CreateCompatibleDC(NULL)) {
    dcBmpNew.SelectObject(bmpNew);
    BITMAP bmSrc;
    m_bmpLogo.GetBitmap(&bmSrc);
    dcBmpNew.FillRect(CRect(0, 0, nWidth, nHeight), &CBrush((COLORREF)0xffffff));
    dcBmpNew.BitBlt(nWidth - bmSrc.bmWidth, 0, bmSrc.bmWidth, bmSrc.bmHeight, &dcBmpSrc, 0, 0, SRCCOPY);
    dcBmpNew.DeleteDC();
    m_imgLogo.SetBitmap(bmpNew);    }
   dcBmpSrc.DeleteDC();
  }
 }
}
