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();
  }
}
}

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::OnSize(nType, cx, cy);
UpdateLogoImage();

}

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.
