Add a String Attachment to an Email

See more Email Object Examples

Demonstrates the Chilkat Email object's AddStringAttachment method, which adds an attachment directly from an in-memory string — no file needs to exist on disk. The 1st argument is the filename that is written into the MIME (it is not a path to a file that is read), and the 2nd argument is the text that becomes the attachment's body. In this example we build a simple email, attach a small CSV file named people.csv straight from a string, and then print the resulting MIME so you can see the attachment embedded in the message.
