Set a MIME Body from Binary Bytes (BinData)

Demonstrates the Chilkat Mime.SetBodyBd method, which sets the decoded body bytes from a BinData, changes the transfer encoding to base64, and preserves the bytes exactly. The only argument is the BinData.

Note: The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background: This is the direct way to put arbitrary binary content into a part from memory — a generated image, a decrypted blob — without a temporary file. Chilkat base64-encodes it so the bytes survive text-based transports unchanged. Note it does not set a Content-Type or disposition, so assign those yourself to describe what the bytes are.
