Demonstrates how to send email with progress monitoring event callbacks.

        // This is the callback to monitor the percentage completion.
        public void OnSendPercentDone(object source, Chilkat.MailPercentDoneEventArgs args)
        {
            progressBar1.Value = args.PercentDone;
            
            // To abort the mail sending before it is complete,
            // set args.Abort = true
            // For example, to abort after 50% completion:
            if (args.PercentDone >= 50)
            {
                args.Abort = true;
            }
        }

        // Send email with progress monitoring.
        private void button5_Click(object sender, EventArgs e)
        {
            Chilkat.MailMan mailman = new Chilkat.MailMan();
            mailman.UnlockComponent("anything for 30-day trial");

            mailman.SmtpHost = "smtp.comcast.net";

            Chilkat.Email email = new Chilkat.Email();
            email.Subject = "this is a test";
            email.Body = "this is the body";
            email.From = "admin@chilkatsoft.com";
            email.AddTo("TagTooga Admin", "admin@tagtooga.com");

            mailman.EnableEvents = true;
            mailman.OnSendPercentDone += new Chilkat.MailMan.SendPercentDoneEventHandler(OnSendPercentDone);

            bool success = mailman.SendEmail(email);
            if (!success)
            {
                MessageBox.Show(mailman.LastErrorText);
            }
            else
            {
                MessageBox.Show("Send Complete!");
            }
        }
