Get the Size of an Attachment
See more Email Object Examples
Demonstrates the Chilkat Email.GetAttachmentSize method, which returns the size in bytes of the attachment at a given zero-based index, or -1 if the index does not identify an existing attachment. This example adds an attachment and prints its size.
Background: The size reported is that of the attachment's actual (decoded) data, not its larger Base64-encoded form on the wire. Knowing per-attachment sizes is handy for enforcing limits, showing a size next to each attachment in a UI, or deciding whether to save or skip a large part. The
-1 sentinel is how the method signals an out-of-range index rather than a zero-length attachment.Chilkat Chilkat2-Python Downloads
