    Hi all, i have written a code to download a webpage using WinInet api's. My code is as follows

    InternetCanonicalizeUrl(site,sCompareURL.GetBufferSetLength(MAX_BUFFER_SIZE),&dwLen,ICU_BROWSER_MODE);
    HINTERNET Ihandle = InternetOpen("Internet Explorer6.0.2900.2180", INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, NULL);
    HINTERNET hFile = InternetOpenUrl(Ihandle,site,NULL,0,0,0);
    BOOL bRet = InternetReadFile(hFile, szBuffer, MAX_BUFFER_SIZE, &nSize);
    if(!bRet || nSize <= 0)
    break;
    szBuffer[nSize] = '\0';
    m_sHtml += szBuffer;

    This code is working fine, but i want to implement time out in this, i.e i the specified page is not download in specified time then time out shold be displayed. How can i implement this? Thanks in advance

      You may try to set an option via InternetSetOption[^] (the INTERNET_OPTION_RECEIVE_TIMEOUT flag looks promising, but I never made a test). :)
