Get a Header Field of a Related Item
See more Email Object Examples
Demonstrates the Chilkat Email.GetRelatedHeader method, which returns the value of a named header field of a related item. The first argument is the zero-based related-item index and the second is the MIME header-field name. This example reads the Content-Type header of a related style sheet.
Background: Each related item is a MIME part with its own header block. Where
GetRelatedAttr extracts a single named parameter from a header, GetRelatedHeader returns the entire value of a header field — for example the full Content-Type or Content-Location line — which is handy for inspecting exactly how an embedded resource is described.Chilkat VB.NET Downloads
