using System;
using System.Collections.Generic;

using System.Web;
using System.Data;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.Security;
using System.Data.SqlClient;

public partial class odgl : System.Web.UI.UserControl
{
    protected void Page_Load(object sender, EventArgs e)
    {

        string connectionString =
  @"SANATIZEDSTRING!!!!";


        using (SqlConnection cn = new SqlConnection(connectionString))
        {


    using (SqlCommand dohvati = new SqlCommand("dbo.get_answers",cn)) {


        dohvati.CommandType = CommandType.StoredProcedure;
        SqlParameter izracun = new SqlParameter("@count", SqlDbType.Int);
        izracun.Direction = ParameterDirection.Output;

        dohvati.Parameters.Add(izracun);

        cn.Open();


        dohvati.ExecuteNonQuery();
        int count = Int32.Parse(dohvati.Parameters["@count"].Value.ToString());

        Response.Write(count.ToString());
