Check Whether an Email Has a Plain-Text Body

Demonstrates the Chilkat Email.HasPlainTextBody method, which returns true only when a text/plain body is present in the current email object. This example sets a plain-text body and confirms its presence.

Background: The plain-text body is the fallback representation used when HTML is unavailable or unwanted — and the form usually preferred for search, indexing, and accessibility. HasPlainTextBody is the counterpart to HasHtmlBody; testing both lets a program handle every combination (text-only, HTML-only, both, or neither) gracefully.
