// First, for the purpose of understanding the structure of the MIME,
// let's load the MIME into a Chilkat MIME object and examine the MIME structure.

success := mime.LoadMimeFile('qa_data/eml/TMobileTextMsg.eml');
// Show the MIME structure in text format (as opposed to XML format).
Memo1.Lines.Add(mime.GetStructure('text'));

// The MIME structure for our test email looks like this:
// multipart/related
//     text/html
//     text/plain
//     image/gif
//     image/gif
//     image/gif

// The HTML part is not considered a "related item" because the related items
// are defined as being related to the HTML part.  Therefore, we should always
// expect to find a text/html part under a multipart/related.  The HTML parts
// is simply the HTML body, and the other parts are the related items.
// If the text/plain part was to be considered as an alternative body,
// then a properly structured email would include a multipart/alternative structure.

email := TChilkatEmail.Create(Self);

success := email.LoadEml('qa_data/eml/TMobileTextMsg.eml');

// We should see 4 related items.
Memo1.Lines.Add('Num Related Items = ' + IntToStr(email.NumRelatedItems));
