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

# Create a text/plain part.
$ptMime = New-Object Chilkat.Mime
$ptMime.SetBodyFromPlainText("This is the plain text body")
$($ptMime.GetMime())
$("****")

# The ptMime contains:
# ---------------------------------------
# 	Content-Type: text/plain
# 	Content-Transfer-Encoding: 7bit
# 
# 	This is the plain text body
# ---------------------------------------

# Start with an empty MIME object...
$topLevelMime = New-Object Chilkat.Mime

# Initialize it to a multipart Content-Type.  We'll use multipart/mixed.
$topLevelMime.NewMultipartMixed()

# Append the ptMime as a child.
$topLevelMime.AppendPart($ptMime)
$($topLevelMime.GetMime())
$("****")

# The topLevelMime contains:
# --------------------------
# 	Content-Type: multipart/mixed; boundary="------------010907090104040508040404"
# 
# 	--------------010907090104040508040404
# 	Content-Type: text/plain
# 	Content-Transfer-Encoding: 7bit
# 
# 	This is the plain text body
# 	--------------010907090104040508040404--
# 

# IMPORTANT: A copy of the MIME passed in AppendPart is appended.
# Therefore, in this case, changing ptMime does not change the text/plain sub-part in topLevelMime.
# For example:
$ptMime.SetBody("this is the new plain text body.")
# topLevelMime is unchanged.
$($topLevelMime.GetMime())
$("****")

# To change the content in topLevelMime, we must get the text/plain part.
# For example:
$ptMime2 = $topLevelMime.GetPart(0)
$ptMime2.SetBody("this is the new plain text body.")

# Now topLevelMime is changed.
$($topLevelMime.GetMime())
