Dim success As Long

' Start with an empty MIME object...
Dim mime As New ChilkatMime

' Initialize it as multipart/alternative.
success = mime.NewMultipartAlternative()

' Create a text/plain part.
Dim ptMime As New ChilkatMime
success = ptMime.SetBodyFromPlainText("This is the plain text body.")
Debug.Print ptMime.GetMime()
Debug.Print "****"

' The text/plain part looks like this:

' 	Content-Type: text/plain
' 	Content-Transfer-Encoding: 7bit
' 
' 	This is the plain text body.

' Create a text/HTML part.
Dim htmlMime As New ChilkatMime
success = htmlMime.SetBodyFromHtml("<html><body><p>This is the <b>HTML body</b></p></body></html>")
Debug.Print htmlMime.GetMime()
Debug.Print "****"

' The text/html part looks like this:

' 	Content-Type: text/html
' 	Content-Transfer-Encoding: 7bit
' 
' 	<html><body><p>This is the <b>HTML body</b></p></body></html>

' Add both parts as children of the multipart/alternative
success = mime.AppendPart(ptMime)
success = mime.AppendPart(htmlMime)
Debug.Print mime.GetMime()

' This the result.  The boundary string was automatically generaetd.

' 	Content-Type: multipart/alternative; boundary="------------080803090906030708030908"

' 	--------------080803090906030708030908
