C# sample code showing how to read email from a POP3 mailbox with percentage completion event callbacks.

	    // This is the progress event callback for reading POP3 email
	    // It can also be used to abort the mail download while in progress.
	    public void OnReadPercentDone(object source, Chilkat.MailPercentDoneEventArgs args)
	    {
		// args.ProgressDone is an integer having a value between 1 and 100
		progressBar1.Value = args.PercentDone;
		
		// args.Abort can be set to true to force the mail download to abort.
		// This example aborts after 75% completion
		if (args.PercentDone >= 75) 
		{
		    args.Abort = true;
		}		
	    }

	    // Read email with progress monitoring.
	    private void button8_Click(object sender, System.EventArgs e)
	    {
		Chilkat.MailMan mailman = new Chilkat.MailMan();
		mailman.UnlockComponent("Anything unlocks for 30-day trial");
		    
		mailman.MailHost = "mail.chilkatsoft.com";
		mailman.PopUsername = "***";
		mailman.PopPassword = "***";
		
		// Enable events and setup a callback
		mailman.EnableEvents = true;
		mailman.OnReadPercentDone += new MailMan.ReadPercentDoneEventHandler(OnReadPercentDone);
		Chilkat.EmailBundle bundle = mailman.CopyMail();
		
		if (bundle == null)
		{
		    MessageBox.Show(mailman.LastErrorText);
		}
		else
		{	    
		    MessageBox.Show("Done!");
		    }
