Visual Basic 6.0

Embed a Message as message/rfc822

Demonstrates the Chilkat Mime.NewMessageRfc822 method, which clears the object and initializes it as a message/rfc822 entity whose body is a serialized copy of another Mime. The only argument is the message to embed.

Background: message/rfc822 wraps a whole email as the body of another — the mechanism behind forwarding a message "as attachment" or bundling one message inside another. The inner message is copied at the time of the call, so later edits to the source do not change the embedded copy. The result is a self-contained part a mail client will present as a nested message.
