The Delphi6\Demos\Indy\NewsReader often freeze up after download the
discussion groups. Does anyone know a better news reader program?

I prefer Agent (from www.forte-inc.com) but if it's unavailable, I use
Outlook express ...

Duh, that should have been www.forteinc.com ;-)

There's a free newsreader available on my website.  It's written in
Delphi 6, uses Indy, and comes with source code.

It's not feature complete yet, but it works, and it's better than the
Demos\Indy\NewsReader one!

My brother undertook the design of a newsreader a few years ago, but said he
was baffled when he tried to locate standards for attachments. Since you
have handled at least some of the issues there, can you point to a reference
or references for the attachment mechanisms?

Thanks,

Bill

You need to do a Google search for 'nntp attachment rfc' and you get a bunch
of stuff, but you also need to test everything in the 'real world', because de
facto standards seem to have evolved.

Basically there seem to be two sorts of attachments, UU Encoded attachments
(usually a single picture) - and MIME attachments.  The UUEncoded attachments
have a message body, follwed by a blank line, followed by
begin nnn filename.ext, the UU Encoded data, and terminated by 'end'

Mime messages can be hugely complicated, they can contain ,multiple sections
and multiple attachments, with instructions to display images inline or simply
present them as an attachment, HTML sections, etc. etc.  It's (sort of)
described in RFC 1521.

I'm not very good at decoding, and I'm sure Indy is better.  The reason I use
my own code for this is I need to display images so that they build up as they
arrive - rather than wait for the entire image once I've received the whole
thing.  That doesn't seem to be possible with Indy.
