Add an Attachment from a BinData Object

Demonstrates the Chilkat Email.AddAttachmentBd method, which adds an attachment using the contents of a BinData object. The first argument is the attachment filename, the second is the BinData, and the third is the content type — if empty, it is inferred from the filename extension. This example loads a PDF into a BinData and attaches it.

Background: BinData is Chilkat's container for raw binary data. Attaching from a BinData is the right approach when the file's bytes are already in memory — generated on the fly, downloaded, or read from a database — rather than sitting on disk (which would use AddFileAttachment). Chilkat Base64-encodes the bytes into the message automatically.
