' 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.
Dim mailman As 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
Dim email As New Chilkat.Email

email.Subject = "This is a vcard test"
email.Body = "This is a vcard test"
email.From = "Chilkat Admin <admin@chilkatsoft.com>"
Dim success As Boolean = 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

Dim vcard As String = "begin:vcard ..."
success = email.AddStringAttachment("admin.vcf",vcard)
If (success <> True) Then
    Debug.WriteLine(email.LastErrorText)
    Exit Sub
End If


' 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 = Await mailman.SendEmailAsync(email)
If (success <> True) Then
    Debug.WriteLine(mailman.LastErrorText)
    Exit Sub
End If


' 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 = Await mailman.CloseSmtpConnectionAsync()
If (success <> True) Then
    Debug.WriteLine("Connection to SMTP server not closed cleanly.")
End If


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