MIME Multipart Boundary and Preamble Properties

See more MIME Examples

Demonstrates the Boundary property, which gets or sets the raw boundary token of a multipart entity (without surrounding quotation marks), and UseMmDescription, which controls whether the conventional preamble text is emitted when serializing a multipart entity.

#  Boundary is the raw boundary token, without surrounding quotation marks.  Chilkat quotes it
#  automatically in the serialized header when required.

#  UseMmDescription controls whether the conventional preamble text
#  "This is a multi-part message in MIME format." is emitted.  The default is 0.

#  Add a simple part so the multipart has content.
