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

//  The mailman object is used for sending and receiving email.
Chilkat.MailMan mailman = new Chilkat.MailMan();

//  Set the SMTP server.
mailman.SmtpHost = "smtp.chilkatsoft.com";

//  Set the SMTP login/password (if required)
mailman.SmtpUsername = "myUsername";
mailman.SmtpPassword = "myPassword";

//  Create a new email object
Chilkat.Email email = new Chilkat.Email();

email.Subject = "This is a vcard test";
email.Body = "This is a vcard test";
email.From = "Chilkat Admin <admin@chilkatsoft.com>";
success = email.AddTo("Chilkat Support","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

string vcard = "begin:vcard ...";
success = email.AddStringAttachment("admin.vcf",vcard);
if (success != true) {
    Debug.WriteLine(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) {
    Debug.WriteLine(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) {
    Debug.WriteLine("Connection to SMTP server not closed cleanly.");
}

Debug.WriteLine("Mail with vCard Sent!");
