    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    var imap = new chilkat.Imap();

    // Turn on session logging:
    imap.KeepSessionLog = true;

    // Connect to an IMAP server.
    // Use TLS
    imap.Ssl = true;
    imap.Port = 993;
    success = imap.Connect("imap.example.com");
    if (success == false) {
        console.log(imap.LastErrorText);
        return;
    }

    // Login
    success = imap.Login("myLogin","myPassword");
    if (success == false) {
        console.log(imap.LastErrorText);
        return;
    }

    // Select an IMAP mailbox
    success = imap.SelectMailbox("Inbox.RubyMail");
    if (success == false) {
        console.log(imap.LastErrorText);
        return;
    }

    // Get the complete set of Uids for email in the selected mailbox.
    var messageSet = new chilkat.MessageSet();
    success = imap.QueryMbx("ALL",true,messageSet);
    if (success == false) {
        console.log(imap.LastErrorText);
        return;
    }

    // Set the Deleted flag for each message.
    // (ExpungeAndClose must be called to finalize the delete.)
    success = imap.SetFlags(messageSet,"Deleted",1);
    if (success == false) {
        console.log(imap.LastErrorText);
        return;
    }

    // Alternatively, the Deleted flag may be set for each UID
    // individiually, but this is less efficient:
    var i = 0;
    var n = messageSet.Count;
    while (i < n) {
        success = imap.SetFlag(messageSet.GetId(i),messageSet.HasUids,"Deleted",1);
        if (success == false) {
            console.log(imap.LastErrorText);
            return;
        }

        i = i+1;
    }

    // Expunge and close the mailbox.
    success = imap.ExpungeAndClose();
    if (success == false) {
        console.log(imap.LastErrorText);
        return;
    }

    // Display the session log.
    console.log(imap.SessionLog);

    // Disconnect from the IMAP server.
    success = imap.Disconnect();
