They Said It Best

So we went to Atari and said, 'Hey, we've got this amazing thing, even built with some of your parts, and what do you think about funding us? Or we'll give it to you. We just want to do it. Pay our salary, we'll come work for you.' And they said, 'No.' So then we went to Hewlett-Packard, and they said, 'Hey, we don't need you. You haven't got through college yet.'
Steve Jobs, cofounder of Apple Computer

Web Forms Codebehind Example

This page builds on our exmple webform contact.aspx page we created in Step 1 ASP.Net Server Controls. When you created contact.aspx using Visual Studio or Visual Web Developer you should have a codebehind page called contact.aspx.cs.

Step 3. Web Form Sending Email Using System.Net.Mail

We had a working "contact us" page in Step 2. Code Behind. Now we want to email the results to the visitor as a confirmation and to the website owner or webmaster. Using the .Net's versatile system.net.mail add the follow subroutine to contact.aspx.cs.

void SendEmail(string status)
{
    try
    {
        MailMessage oMsg = new MailMessage();
        oMsg.BodyFormat = MailFormat.Html;
        oMsg.Subject = "Really Cool Web Design Request";
        oMsg.Body = "<html><body>";

        if (status == "GUEST") {
            oMsg.To = email.Text;
            oMsg.From = "info@website-designguide.com";

            oMsg.Body += "<p> This is an automatic email ";
            oMsg.Body += "indicating that we have received your request for ";
            oMsg.Body += "more information about really cool web designs.</p>";
            oMsg.Body += "Someone will be contacting you shortly.</p>";              
            
        }
        else
        {
            oMsg.Headers.Add("Reply-To", email.Text);
            oMsg.To = "info@website-designguide.com";
            oMsg.From = "webmaster@webmaster-designguide.com";
            oMsg.Body +="You have received an information request from the person ";
            oMsg.Body +="listed below.</p>;

            oMsg.Body += "<p>Full Name: " + FName.Text + " " + LName.Text;
            oMsg.Body += "<br>Address:   " + Street.Text;
            oMsg.Body += "<br>City:      " + City.Text;
            oMsg.Body += "<br>State:     " + State.Text;
            oMsg.Body += "<br>Zipcode:   " + Zip.Text;
            oMsg.Body += "<br>Email:     " + email.Text;
            oMsg.Body += "<br>Phone:     " + Telephone.Text;
            oMsg.Body += "<br>Contact Me:     " + Contactme.Text;

            if (Question.Text != null){
                oMsg.Body += "<br><b>Question(s):</b>";
                oMsg.Body+=<br><br>" + Server.HtmlEncode(Question.Text);}

            oMsg.Body += "</p>";
        }

        oMsg.Body += "<p>&nbsp;";
        oMsg.Body += "<p>Website Design Guide<br>";
        oMsg.Body += "http://www.website-designguide.com<br>";
        oMsg.Body += "<p>&nbsp;";
        oMsg.Body += "</body></html>";

        // ADD AN ATTACHMENT.
        // TODO: Replace with path to attachment.
        //String sFile = @"D:\FTP\username\Htdocs\Hello.txt"; 
        //MailAttachment oAttch = new MailAttachment(sFile, MailEncoding.Base64);
        //oMsg.Attachments.Add(oAttch);

        // TODO: Replace with the name of your remote SMTP server.
        SmtpMail.SmtpServer = "mail.yourserver.com";
        SmtpMail.Send(oMsg);

        oMsg = null;
        //oAttch = null;
    }
    catch (Exception e)
    {
        Console.WriteLine("{0} Exception caught.", e);
    }
}

Now in the onclick subroutine for frmValidate we include 2 calls to the SendEmail() subroutine. One call is for the guest and once to the webmaster or site owner:
SendEmail("GUEST");
SendEmail("POC");
