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

Dim mime As New Chilkat.Mime

Dim success As Boolean = mime.SetBodyFromFile("VoiceMessage.wav")
If (success = False) Then
    Debug.WriteLine(mime.LastErrorText)
    Exit Sub
End If



' The MIME has this header:
' Content-Disposition: attachment;
' 	 filename="VoiceMessage.wav"
' Content-Transfer-Encoding: base64
' Content-Type: audio/x-wav;
' 	name="VoiceMessage.wav"

' We don't want the content-disposition to be an
' attachment -- otherwise the email object will self-correct
' and put it in a multipart/mixed format...
mime.Disposition = ""
mime.Filename = ""

Dim strMime As String
strMime = mime.GetMime()
Debug.WriteLine(strMime)

' Now load it into an email object:
Dim email As New Chilkat.Email
success = email.SetFromMimeText(strMime)
If (success = False) Then
    Debug.WriteLine(email.LastErrorText)
    Exit Sub
End If


' Add subject, TO, FROM, etc.
email.Subject = "This is a test"
email.From = "support@chilkatsoft.com"
success = email.AddTo("Matt","matt@chilkatsoft.com")

' Your email is ready to send.
' (but for this example, we'll simply save it to a file...)
success = email.SaveEml("email.eml")
If (success = False) Then
    Debug.WriteLine(email.LastErrorText)
    Exit Sub
End If


Debug.WriteLine("OK!")
