Create C# webform for email submission using SMTP

Thank you for your response. I am more clueless than I realized. I'm going to start posting the entire aspx.cs page.

I made the changes suggested above and now have new build errors. . .

1.Make sure that the class defined in this code file matches the 'inherits' attribute, and that it extends the correct base class (e.g. Page or UserControl).   //*this causes Default2 to be underlined*

2.'ASP.submitform_aspx.GetTypeHashCode()': no suitable method found to override

3.'ASP.submitform_aspx.ProcessRequest(System.Web.HttpContext)': no suitable method found to override      
      
4.'ASP.submitform_aspx' does not implement interface member 'System.Web.IHttpHandler.IsReusable'      

Code is now:

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Net;
using System.Net.Mail;
using System.Net.Mime;
using System.Threading;
using System.ComponentModel;
namespace Examples.SmptExamples.Async
{

    public partial class Default2 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
        }

        protected void TextBox2_TextChanged(object sender, EventArgs e)
        {

        }
        protected void Button1_Click(object sender, EventArgs e)
        {
            try
            {
                System.Net.Mail.MailMessage mailObj = new System.Net.Mail.MailMessage();

                //set user authentication
                mailObj.UserName = "LogonServerAccountName";
                mailObj.Password = "pleasehelp";

                //specifies the authentication mechanism.
                mailObj.AuthType = SmtpAuthType.AuthAuto;

                //set SSL connection
                mailObj.ConnectType = SmtpConnectType.ConnectSSLAuto;

                //set smtp server port (Port 25 blocked by my isp so using alternate one)
                mailObj.Port = ###;

                //set helo domain
                mailObj.HeloDomain = "myURL.com";

                //set delivery-report address
                mailObj.MailFrom = "you@myURL.com";

                mailObj.From = "me@myURL.com";
                mailObj.To.Add = "DoNotRespond@myURL.com";

                mailObj.Subject = " Submission Form";
                mailObj.Body = "This is sample text";
                mailObj.BodyFormat = MailFormat.Text;
                mailObj.SmtpServer = "myURL.com";
                mailObj.Send(mailObj);
                System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient("myURL.com");
                Response.Write("Mail sent successfully");
            }
            catch (Exception x)
            {
                Response.Write("Your message was not sent: " + x.Message);
            }

        }
        protected void FirstNameTxt_TextChanged(object sender, EventArgs e)
        {

        }
        protected void LastNameTxt_TextChanged(object sender, EventArgs e)
        {

        }
        protected void TitleTxt_TextChanged(object sender, EventArgs e)
        {

        }
    }
}

I'm glad you said that. I'd love to talk about the concepts so I can learn more. I was afraid that if the discussion got too long or there were too many time gaps in the conversation, you would lose interest.

I'm having problems with the automatic code generated by Visual Studio. I have tried several ways to code this form. The previous ways I coded things created automatic code I need to change, but I don't know the right way to do it.

I have discovered commenting out this code leads to either more errors or new automatically generated code that recreates the same errors. Deletion of sections of code and deletion of the file the code is in also lead to more errors.

When I had this problem previously, I would create a new file and start over.  I would leave the old file (and it's automatically generated code) in the project. However, I have finally gotten the page to look how I want it to look and am reluctant to start over for the 3rd time.

Any suggestions?
