Count the Messages in a multipart/digest Email
See more Email Object Examples
Demonstrates the read-only Chilkat Email.NumDigests property, which is the number of message/rfc822 parts contained within a multipart/digest enclosure. If no such enclosure exists, the value is 0. Digest indexes are zero-based; use GetDigestEmail to retrieve an individual bundled message as its own Email object. This example loads a digest email and lists each message's subject.
Background: A
multipart/digest is a way to package many separate emails inside one carrier message — historically used by mailing lists to send a single daily "digest" containing all of that day's posts. Each bundled item is a complete message/rfc822 email with its own headers and body. This differs from NumAttachedMessages, which counts nested messages attached to an ordinary email rather than the members of a digest enclosure.Chilkat Visual Basic 6.0 Downloads
