    // The mailman object is used for sending and receiving email.
    CkMailManW mailman;

    // Set the SMTP server.
    mailman.put_SmtpHost(L"smtp.chilkatsoft.com");

    // Set the SMTP login/password (if required)
    mailman.put_SmtpUsername(L"myUsername");

    // Create a new email object
    CkEmailW email;

    email.put_Subject(L"This is a vcard test");

    email.put_From(L"Chilkat Admin <admin@chilkatsoft.com>");
    bool success = email.AddTo(L"Chilkat Support",L"support@chilkatsoft.com");
    // To add more recipients, call AddTo, AddCC, or AddBcc once per recipient.

    // A vCard is an email attachment having a Content-Type = "text/x-vcard".
    // Call AddStringAttachment to add a vcard from an in-memory string.
    // The filename should have a ".vcf" file extension.  Chilkat will automatically
    // recognize it and set the content-type to "text/x-vcard";

    // Your application is responsible for providing the vcard formatted string.  For example:
    // See http://en.wikipedia.org/wiki/VCard
    // 
    // begin:vcard
    // fn:Matt Smith
    // n:Smith;Matt
    // org:Chilkat Software, Inc.
    // tel;work:630-784-9670
    // url:http://www.chilkatsoft.com
    // version:2.1
    // end:vcard

    const wchar_t *vcard = L"begin:vcard ...";
    success = email.AddStringAttachment(L"admin.vcf",vcard);
    if (success != true) {
        wprintf(L"%s\n",email.lastErrorText());
        return;
    }

    // Call SendEmail to connect to the SMTP server and send.
    // The connection (i.e. session) to the SMTP server remains
    // open so that subsequent SendEmail calls may use the
    // same connection.  
    success = mailman.SendEmail(email);
    if (success != true) {
        wprintf(L"%s\n",mailman.lastErrorText());
        return;
    }

    // Some SMTP servers do not actually send the email until 
    // the connection is closed.  In these cases, it is necessary to
    // call CloseSmtpConnection for the mail to be  sent.  
    // Most SMTP servers send the email immediately, and it is 
    // not required to close the connection.  We'll close it here
    // for the example:
    success = mailman.CloseSmtpConnection();
    if (success != true) {
        wprintf(L"Connection to SMTP server not closed cleanly.\n");
    }

    wprintf(L"Mail with vCard Sent!\n");
