Get a Header Attribute of an Attachment
See more Email Object Examples
Demonstrates the Chilkat Email.GetAttachmentAttr method, which returns a header-field attribute value from a header field of the Nth attachment. The first argument is the zero-based attachment index, the second names a header field, and the third names an attribute within it. This example reads the filename attribute of the attachment's Content-Disposition header.
Background: A MIME header can have named parameters after its main value, such as
Content-Type: text/plain; charset="utf-8"; name="notes.txt". Here charset and name are attributes. GetAttachmentAttr pulls out one named attribute from a chosen header of a specific attachment, sparing you from parsing the raw header string and dealing with quoting or ordering.Chilkat VB.NET Downloads
