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

' Start with an empty MIME object...
set mime = CreateObject("Chilkat.Mime")

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

' Create a text/plain part.
set ptMime = CreateObject("Chilkat.Mime")
success = ptMime.SetBodyFromPlainText("This is the plain text body.")
outFile.WriteLine(ptMime.GetMime())
outFile.WriteLine("****")

' 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.
set htmlMime = CreateObject("Chilkat.Mime")
success = htmlMime.SetBodyFromHtml("<html><body><p>This is the <b>HTML body</b></p></body></html>")
outFile.WriteLine(htmlMime.GetMime())
outFile.WriteLine("****")

' 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)
outFile.WriteLine(mime.GetMime())

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

' 	Content-Type: multipart/alternative; boundary="------------080803090906030708030908"
' 
' 	--------------080803090906030708030908
' 	Content-Type: text/plain
' 	Content-Transfer-Encoding: 7bit

' 	This is the plain text body.
