Attach a File to an Email

Demonstrates the Chilkat Email.AddFileAttachment method, which attaches a file read from the filesystem. It returns the content type Chilkat assigned to the attachment (inferred from the file extension). This example attaches a PDF and prints its detected content type.

Background: Each attachment carries a Content-Type (MIME type) such as application/pdf or image/png that tells the receiving client how to handle it. Chilkat gets this from the file's extension. Because attachment bytes are binary, they are Base64-encoded for transport, which is handled automatically — you simply point AddFileAttachment at a path and the file is read, encoded, and packaged into the message.

#  Demonstrates the AddFileAttachment method, which attaches a file read from the
#  filesystem.  It returns the content type Chilkat assigned to the attachment (based on
#  the file extension), or returns failure if the file could not be read.

email = Chilkat::CkEmail.new()
email.put_Subject("Email with a file attachment")
email.put_Body("Please see the attached file.")

#  Attach a file.  The return value is the auto-detected content type.
contentType = email.addFileAttachment("qa_data/attachments/report.pdf")
if (email.get_LastMethodSuccess() == false)
    print email.lastErrorText() + "\n";
    exit
end

print "Attached content type = " + contentType + "\n";
print "NumAttachments = " + email.get_NumAttachments().to_s() + "\n";

#  Note: The path "qa_data/attachments/report.pdf" is a relative local filesystem path,
#  relative to the current working directory of the running application.
