Add an Attachment from a BinData Object

See more Email Object Examples

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.

// Demonstrates using the Chilkat Pascal wrapper via the C bridge DLL.
