Re: Problem in Cimage

Hi,
I m trying to download and display image.My code works fine for some
time.After that i gives debug assertion error after CImage m_image;
at line 504 ATLASSERT( hBitmap != NULL );,1572 ATLASSERT( nBytes ==
sizeof( BITMAP ) );,630ATLASSUME( m_hBitmap != NULL ); on
altimage.h.

I try to debug but unable to finderror. m_picturecontrol is picture
control from
http://www.codeproject.com/KB/graphics/CPictureControl.aspx?display=Print

void CScreenclientDlg::Downloadfile()
{
CString strHeaders = _T("Content-Type: image/gif");
CInternetSession pSession;

CString strQueryTemp, strQuery;
//CString strResponse;
strQueryTemp.LoadString(IDS_DOWNLOADFILE);
strQuery.Format(strQueryTemp,accountno,sessid,sno);
strQuery=L"http://www.mydomain.com/"+strQuery;

pFile=pSession.OpenURL
(strQuery);//,NULL,INTERNET_FLAG_DONT_CACHE,NULL,NULL);
if (pFile)
{
IStream* pStream;
CImage m_image;

if(CreateStreamOnHGlobal(NULL, TRUE, &pStream) == S_OK)
{
BYTE pBuffer[1024];
UINT uiRead = 0;
ULONG ulWrittencount=0;

while((uiRead = pFile->Read(pBuffer, sizeof(pBuffer))) != 0)
{
ULONG ulWritten = 0;
pStream->Write(pBuffer, uiRead, &ulWritten);

}

lock=TRUE;

HRESULT hr=m_image.Load(pStream);

{m_CtrlHeight=m_image.GetHeight();
m_CtrlWidth=m_image.GetWidth();
RedrawWindow();
}
m_picturecontrol.FreeData();

m_picturecontrol.SetWindowPos(NULL,0,0,m_image.GetWidth
(),m_image.GetHeight(),SWP_NOMOVE | SWP_NOZORDER);
Invalidate();
RedrawWindow();

BOOL bResult= m_picturecontrol.Load(pStream);
pSession.Close();

m_image.Detach();
m_image.Destroy();
lock=FALSE;
         }oldsno=sno;
while(pStream->Release());

}
delete pFile;

}
catch(CException *e)
{

AfxBeginThread(threading, this);

return;
}

AfxBeginThread(threading, this);

}
}

UINT CScreenclientDlg::threading1(LPVOID p)
{ CScreensharingclientDlg * me = (CScreensharingclientDlg *)p;

    me->showimage(me->count);

    return 0 ;
}
