    <p>I know this question has been asked but I don't see anything that helps me. What I have is a ticket application that records trouble tickets then sends an email to the right person. When I run this on my machine it works, but on my server I get a <strong>Null object reference</strong> error.</p> <pre><code>using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Collections; using System.Configuration; using System.Data; using System.Web.Security; using System.Web.UI.HtmlControls; using System.Web.UI.WebControls.WebParts; using System.Xml.Linq; using Oracle.DataAccess.Client; using System.Text; using System.Data.OleDb; using System.Windows.Forms; using System.IO; using System.Diagnostics; using System.Net.Mail; namespace Ticketing { public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { "201157"; } protected void btn_submit_Click(object sender, EventArgs e) { DateTime dtnow = DateTime.Now; OracleConnection conn = new OracleConnection(Global.oracle); conn.Open(); StringBuilder sqls = new StringBuilder("Insert statment") OracleCommand cmd = new OracleCommand(sqls.ToString(), conn); cmd.CommandType = CommandType.Text; cmd.Parameters.Add(":REASON", txt_reason.Text); cmd.ExecuteNonQuery(); cmd.Dispose(); conn.Close(); // end insert System.Threading.Thread.Sleep(2000); btn_refresh_Click(null, null); btn_email_Click(null, null); //send email MailMessage mail = new MailMessage(); mail.From = new MailAddress("email@email.com"); if (dd_urgency.SelectedValue.ToString() == "Critical") { mail.To.Add("email@email.com"); mail.To.Add("email@email.com"); mail.To.Add("email@email.com"); mail.To.Add(lbl_email.Text); } else if (dd_urgency.SelectedValue.ToString() == "Urgent") { mail.To.Add("email@email.com"); mail.To.Add("email@email.com"); mail.To.Add("email@email.com"); mail.To.Add(lbl_email.Text); } else if (dd_urgency.SelectedValue.ToString() == "Normal") { mail.To.Add("email@email.com"); mail.To.Add(lbl_email.Text); if (dd_location.SelectedValue.ToString() == "XL") { mail.To.Add("email@email.com"); } } else if (dd_urgency.SelectedValue.ToString() == "None") { mail.To.Add("email@email.com"); mail.To.Add(lbl_email.Text); if (dd_location.SelectedValue.ToString() == "XL") { mail.To.Add("email@email.com"); } } mail.IsBodyHtml = true; mail.Subject = ("Ticket Id " + (label_id.Text) +" Urgency: " + dd_urgency.SelectedValue.ToString()) + " At " + (dd_location.SelectedValue.ToString()); mail.Body = txt_reason.Text; SmtpClient smtp = new SmtpClient("basic.smtp.ttu.edu"); try { smtp.Send(mail); } catch (SmtpException ex) { Response.Write("&lt;script&gt;alert('There has been an error please call Travis Jorge at ')&lt;/script&gt;"); } // this.Session.Abandon(); Response.Write("&lt;script&gt;alert('You have submitted your trouble ticket we will be right with you.

Any help would be appreciated. Also I know that all the values requested for the objects are available to the page.</p>

    3. COPlease don't format your code as a blockquote, format it as code. Hit the `{}` button beside the `""`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
