What can cause error 12007 when calling HttpSendRequest?

Question

GCC

Completely identical programs compiled in Dev-Cpp (GCC) and MS VS 2008 Express work the same in Windows 7. But for some reason, only compiled in GCC works in Windows 8.1. VS2008 + W8.1 - not downloadable.

Answer 1

Only a debugger will help here. The reason seems to be that the GCC program carries a part of the standard library with it, while the vizhakov one takes it from Windows.

Answer 2

HINTERNET hInternet, hConnect, hRequest;
    unsigned long readbytes = 0;

  char buffer[1024];

  hInternet = InternetOpen ( "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322)", INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0 );

    if ( hInternet )
    {
        hConnect = InternetConnect( hInternet, "site.com", INTERNET_DEFAULT_HTTP_PORT, NULL, NULL, INTERNET_SERVICE_HTTP, 0, 0 );
        if ( hConnect )
        {
            hRequest = HttpOpenRequest ( hConnect, "GET", url, NULL, NULL, NULL, INTERNET_FLAG_NO_COOKIES | INTERNET_FLAG_RELOAD | INTERNET_FLAG_RESYNCHRONIZE | INTERNET_FLAG_NO_UI | INTERNET_FLAG_HYPERLINK, 0 );
            if ( hRequest )
            {
                if ( HttpSendRequest( hRequest, NULL, 0, NULL, 0 ) )
                {
                    if ( InternetReadFile ( hRequest, buffer, 1024, &readbytes ) )
                    {

                        if ( readbytes )
                        {
                                   /* ....... */
                        }
                    }
        }
      }
      InternetCloseHandle ( hRequest );
    }
    InternetCloseHandle ( hConnect );
  }	
  InternetCloseHandle ( hInternet );
