Can Someone Help me figure this out? Not only finding multiparts

P: n/a
Here is the code I have so far. It connects to a db and grabs headers.
It then sorts them into groups and then puts all the complete ones
into another table. Problem I am having is that for some reason now it
is not finding ones that are single posts. Here is an example of a
header for a single.

You've posted a lot of code. Which bit is failing - the SQL, the
regular expression? If you could change your code into a *short* but
complete example, that would really help.

See http://www.pobox.com/~skeet/csharp/complete.html for details of
what I mean by that.

sorry about that. But I did happen to just find the problem. I was
adding them to the group and checking for it to be complete when it
added one to an existing group but not checking for completion when it
made a new group.
