JIF(m_pGB->AddSourceFilter(wFile, L"UrlFilter", &m_UrlSource));
IPin * pOut=NULL;
hr = g_OpenPrg->QueryProgress(<otal, &lreceive);
Why hr is failed??? I can not get the total length and download length of the file, the file url is like "mms://18.104.22.168/test.wmv" or "http://22.214.171.124/test.wmv"
