            strConnString = "Server=localhost;User Id=root; Password=root; Database=mydatabase; Pooling=false;";
            objConn.ConnectionString = strConnString;
            objConn.Open();

            //*** DataTable ***'
            MySqlDataAdapter dtAdapter = default(MySqlDataAdapter);
            DataTable dt = new DataTable();
            strSQL = "SELECT * FROM files WHERE FilesID = ?sFilesID ";
            dtAdapter = new MySqlDataAdapter(strSQL, objConn);
            objCmd = dtAdapter.SelectCommand;
            objCmd.Parameters.Add("?sFilesID", MySqlDbType.Int32).Value = Request.QueryString["FilesID"].ToString();
            dtAdapter.Fill(dt);

            if (dt.Rows.Count > 0)
            {
                Response.ContentType = dt.Rows[0]["FilesType"].ToString();
                Response.BinaryWrite((byte[])dt.Rows[0]["FilesName"]);
            }

            dt = null;
