Question

I’m a new programmer trying to understand someone else’s code. The program’s purpose is to put MySQL data into a word file template using bookmarks. AR and ICN are 2 types of reports, thus they each have their own template. The code was originally containing only AR’s, I have now added ICN. The console application works well, I have problems with the Web page. I don’t understand why the if (int.TryParse(ticketId, out currentTicket)) in my code is FALSE which generates a default.aspx .

Trying to view in broswer this code

using System;
using System.Web;
using TicketExtractionLibrary;

namespace TicketExtractionWeb
{
    public partial class GetAR : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            string ticketId = Request.QueryString["TicketId"];
            int currentTicket;

            string applicationPath = Request.PhysicalApplicationPath;
            ARExtractionController ARController = new ARExtractionController();

            string arTemplateLocation = HttpContext.Current.Server.MapPath("~/AR.dot");
            string mappingLocation = HttpContext.Current.Server.MapPath("~/ARmapping.xml");

            if (int.TryParse(ticketId, out currentTicket))
            {
                ARController.Extract(currentTicket, applicationPath + "LastTickets", arTemplateLocation, mappingLocation);

                Response.Clear();
                Response.Buffer = true;
                Response.ContentType = "application/msword";
                Response.AddHeader("content-transfer-encoding", "binary");
                Response.AddHeader("content-disposition", "attachment;filename=AR" + ticketId + ".docx");

                Response.ContentEncoding = System.Text.Encoding.GetEncoding(1251);

                string path = Server.MapPath(@"\LastTickets\AR" + ticketId + ".docx");
                System.IO.FileInfo file = new System.IO.FileInfo(path);

                Response.WriteFile(path);

                Response.End();
            }
            else
            {
                Response.Redirect("Default.aspx");
            }
        }
    }
}

Answer 1

It is saying, if the TicketID passed via the querystring is not an integer, then there is no report or Word document to generate, therefore redirect the user to the default.aspx page.
