success := False;

// 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.
mailman := CkMailMan_Create();

// Set the SMTP server.
CkMailMan_putSmtpHost(mailman,'smtp.chilkatsoft.com');

// Set the SMTP login/password (if required)
CkMailMan_putSmtpUsername(mailman,'myUsername');
CkMailMan_putSmtpPassword(mailman,'myPassword');

// Create a new email object
email := CkEmail_Create();

CkEmail_putSubject(email,'This is a vcard test');

CkEmail_putFrom(email,'Chilkat Admin <admin@chilkatsoft.com>');
success := CkEmail_AddTo(email,'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

vcard := 'begin:vcard ...';
success := CkEmail_AddStringAttachment(email,'admin.vcf',vcard);
if (success <> True) then
  begin
    Memo1.Lines.Add(CkEmail__lastErrorText(email));
    Exit;
  end;

// 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 := CkMailMan_SendEmail(mailman,email);
if (success <> True) then
  begin
    Memo1.Lines.Add(CkMailMan__lastErrorText(mailman));
    Exit;
  end;

// 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 := CkMailMan_CloseSmtpConnection(mailman);
if (success <> True) then
  begin
    Memo1.Lines.Add('Connection to SMTP server not closed cleanly.');
  end;

Memo1.Lines.Add('Mail with vCard Sent!');
