Chapter 9/10 problem

Nick Makin · January 5th, 2012, 09:15 AM

Ever since the exercises on chapter 9 where you have to send emails my code has had a few problems. Now in my ContactForm when I try and submit it wont work, it used to give the error message "Could not find a part of the path 'C:\BegASPNET\Site\App_Data\ContactForm.txt" and said there was a problem in the line of code:

Code:

string mailBody = File.ReadAllText(fileName);

The line in my code

Code:

FormTable.Visible = false;

doesent compile, says that it doesent exist in current context so ive had to comment it out.

Ive tried to move on but all exercises go back to this contact form, so feel I need to fix these two problems before I deal with any others.

Any help would be apprieciated,

Nick

Did you notice the line before you posted. it is something like this

Code:

string fileName = Server.MapPath("~/App_Data/ContactForm.txt");

may be you have not created ContactForm.txt file in App_Data folder of your application or you must check for permissions to the App_Data folder (atleast read write)

If this:

Code:

FormTable.Visible = false;

doesn't compile, check the markup of the page. Did you add Id and Runat attributes to the table?

You may want to look at the code for the book that you can download from this site, and see if you can spot the differences. Otherwise, please post the full code for the control.

Cheers,

Thanks for the reply, no luck with the FormTable, still doesent compile for some reason.

Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.IO;
using System.Net.Mail;

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

    }
    protected void CustomValidator1_ServerValidate(object source, ServerValidateEventArgs args)
    {
        if (!string.IsNullOrEmpty(PhoneHome.Text) ||
               !string.IsNullOrEmpty(PhoneBusiness.Text))
        {
            args.IsValid = true;
        }
        else
        {
            args.IsValid = false;
        }

    }
    protected void SendButton_Click(object sender, EventArgs e)
    {
        if (Page.IsValid)
        {
            string fileName = Server.MapPath("~/App_Code/ContactForm.txt");
            string mailBody = File.ReadAllText(fileName);

            mailBody = mailBody.Replace("##Name##", Name.Text);
            mailBody = mailBody.Replace("##Email##", EmailAddress.Text);
            mailBody = mailBody.Replace("##HomePhone##", PhoneHome.Text);
            mailBody = mailBody.Replace("##BusinessPhone##", PhoneBusiness.Text);
            mailBody = mailBody.Replace("##Comments##", Comments.Text);

            MailMessage myMessage = new MailMessage();
            myMessage.Subject = "Response from web site";
            myMessage.Body = mailBody;

            myMessage.From = new MailAddress("[email protected]", "Sender Name");
            myMessage.To.Add(new MailAddress("[email protected]", "Receiver Name"));

            SmtpClient mySmtpClient = new SmtpClient();
            mySmtpClient.Send(myMessage);

            Message.Visible = true;
            FormTable.Visible = false;
        }
    }
}

And here is the markup for the table

Code:

<ContentTemplate>
<table id="ContactForm1" class="style1" runat="server">
    <tr>
        <td colspan="3" 
            style="font-weight: 700; text-decoration: underline; font-size: medium">
            <span class="style5">Get in touch with us!<br />
            </span>
            <br />
            Please complete this contact form in order for us to contact you.</td>
    </tr>
    <tr>
        <td class="style8">
            Name.</td>
        <td class="style3">

Your table has an ID of ContactForm1, not FormTable....

Hope this helps,
