MIME Component [IP*Works! V8]

Properties Methods Events Configuration Settings

The MIME component allows for easy implementation of the Multipurpose Internet Mail Extensions or MIME as defined in RFC 1521 and updated in RFCs 2045-2049. Those standards provide for formating of messages containing non-text, multipart or non 'US' formated text.

NOTE: What follows is a very short description of the component interfaces. For more information, please consult the help files that come with the respective package.

Remarks

The component may be used for decoding or encoding of messages. Message holds the content of the encoded message or the filename which holds the encoded data. The decoded data is provided in Parts properties .

To decode a MIME message you should first assign either the whole message (headers and body) to Message or put the message headers into the MessageHeaders property and the message body or the filename holding it into the Message property. Calling DecodeFromFile or DecodeFromString directs the component to start parsing the message: it will fill out the ContentType, ContentTypeAttr properties with message content type information, and enter information about message parts into the Parts properties , which includes: part sizes, part content types, part content type attributes, part content disposition, part content disposition attributes, part encoding, part name, part filename, part headers, or part content (part decoded string or part decoded file) for each decoded part.

Calling the DecodeFromString or DecodeFromFile to decode doesn't actually decode the message but only parses it. The real decoding is done when the part content in the Parts properties is first accessed.

To encode data into a MIME message you should first assign values for each part to either part decoded string or part decoded file in the Parts properties property, and optionally assign values to the other part attributes in the Parts properties . Assigning a value to the part decoded string or part decoded file through the Parts properties , fills out automatically the part headers into the Parts properties for the respective part. Calling EncodeToFile or EncodeToString directs the component to fill out the Message with the message body and the MessageHeaders with the headers.

The Progress event is fired as the message is parsed and the data is decoded/encoded.
