Thanks for the reply.
Here's a little background. I am building a VB.NET News Reader and can
successfully list news groups, and messages in each newsgroup. A response
from the server for a posted message will look like below.
I am trying to display the posts in a thread, much like you see in outlook
or any other news reader. There References Header seems to be the only
thing that relates the post to one another. I was trying to use the check
command which requires authentication, to look up the corresponding
crossposts. It seems that the only way I can cross reference the post is to
do this:
Query the news server for a list of posts in a group, and then use the HXDR
command to gets the message-id for every post. Once I have the headers, I
need to loop through all the headers and match the reference ID to the
Article ID. Once I have the Article ID for each referenced post I can then
lookup each post listed in the references header. This seems like a pain
with lots of uneccesary communication between the client and the server.
Does anyone know of an easier way to do this?

The microsoft news server does not require a password to be sent to login to
it.
Why don't you login directly to the Microsoft news server (
msnews.microsoft.com ) ?
Just create an account for msnews.microsoft.com in Outlook Express...and
login.
I wouldn't include a real email address, though.
Either garble it a bit...or use a fake one.

Shortened for brevity, this will get the last one hundred headers, in
actuality you may have to query thousands of headers.

Now that I have the message-id of the last 100 posts, loolp through each
until I find the reference id's
Dim References() as string = new string()
{"<
[email protected]>",
"<
[email protected]>"}
for I as integer = 0 to ubound(split(XHDR, vbnewline))
for j as integer = 0 to ubound(references)
if split(XHDR, vbnewline)(i).split(" ")(1) = referenences(j) then
References(j) = split(XHDR, vbnewline)(i).split(" ")(0)
next
next
return references
Now There references *should* contain the corrersponding articleID
' References(0) = 483074 References(1) = 483075
For I as integer =0 to ubound(references)
Dim article as string = GetArticle(references(i)
next
Function GetArticle(byval ArticleID as integer)
NNTP.Query("Article " & articleID & environment.newline)
End function
Client: Article 483075
Server: ----- Returns Articles similar to that above.
As you can see, there seems to be a lot of overhead head here going back and
forth. Is this how it needs to be done or is there a simpler way?
