Add a Custom Header to an Email Attachment
See more Email Object Examples
Demonstrates the Chilkat Email.AddAttachmentHeader method, which adds a custom MIME header field to an existing attachment identified by its zero-based index. This example adds an attachment (which becomes index 0), then attaches an extra header field to it and prints the resulting MIME.
Background: In MIME, every attachment is itself a mini-message with its own small block of headers — things like
Content-Type, Content-Disposition, and Content-Transfer-Encoding that describe that specific part. AddAttachmentHeader lets you insert additional fields into that per-part header block, which is occasionally needed for interoperability with systems that look for custom X- headers or content identifiers on individual attachments.Chilkat Visual FoxPro Downloads

* Add an attachment; it becomes attachment index 0.
loEmail.AddStringAttachment("data.txt","Attachment body.")
* Add a custom header field to the first attachment (index 0).
loEmail.AddAttachmentHeader(0,"X-Custom-Attachment-Header","some value")
* The custom header now appears in the attachment's MIME part.
