        HINTERNET hFile = InternetOpenUrl(hInternet, pUrl, 0, 0, INTERNET_FLAG_RELOAD, 0);

        if (hFile)

        {

            int code = 0;

            DWORD length = sizeof(int);

            HttpQueryInfo(hFile, HTTP_QUERY_STATUS_CODE | HTTP_QUERY_FLAG_NUMBER, &code, &length, 0);

            bValid = code == HTTP_STATUS_OK || code == HTTP_STATUS_REDIRECT;

            InternetCloseHandle(hFile);

        }

        InternetCloseHandle(hInternet);

    }

    return bValid;

}

int main()

Since you can't seem to form a question, The above useragent and open type could be giving you issues.

This may or may not fix it, Just a heads up the original code is not a dll.

well it's not fixed and how u mean it's not a dll ? :/

It's obviously not a DLL because the signature for a DLL is much different.

Why don't you read up on how to make a DLL rather than just begging for a solution. It should be obvious that this is not a DLL
