NNTP Question

[Bishop]

I'm using VB.NET with Sockets to read newsgroup content. I seem to have
everything working good but when I read the messages in the newsgroup I
don't seem to get the most recent messages. I issue the "Group" command
which gives me the oldes and newest message number and I'm able to loop
through and retrieve all of them but my in Outlook Express I can find new
messages that my application didn't download. Any thoughts on what I might
be missing?

Hi,

As long as you have not issued any next or last commands you shoud get the
most recently posted messages in reverse order. Another command you might
want to try is newnews

Thanks for the info and link. Looking at this closer, I think that the
MessageNumber (not Message ID) may not always be consistant. For example
when I query with the group command, it would respond with the start and
finish MessageNumbers such as:
First 419520
Last 439948

When I loop through using the Article command, it don't always get a
response for every message (more so on the larger groups with lots of
messages) so I continue to loop through until I've retireved all of them.
It seems that MessageNumber 419640 (for example) may get a different message
when I query the server for it at different times.

OK, my bad, I had set a timeout and I think what was happening is I was
reading data from a previous write. Seems to be working good now.
