Check Whether an Email Has an HTML Body

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

Background: Because a message may contain a plain-text body, an HTML body, both, or neither, it is good practice to test before extracting. HasHtmlBody lets you decide whether to call GetHtmlBody or fall back to GetPlainTextBody — avoiding surprises when a sender provides only one representation.
