Get the Entire MIME Header Section

Demonstrates the Chilkat Mime.GetEntireHead method, which returns the complete serialized header section of the current entity. It takes no arguments; the body and any multipart child content are not included.

Note: The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background: This gives you just the headers of the current entity as text — the block above the blank line that separates headers from body. It is convenient for logging or displaying a message's metadata, or for examining the headers without the potentially large body. Its complement is GetEntireBody.
