No, there aren't an infinite loop on accept. And yeah, it just sits in the accept call.

Then it is working as written.

I'm guessing you need that to be asynchronous instead of halting the thread, correct?
If so, you can do one of these:
1) Leave the listener socket in blocking mode and put the accept call in a different thread.
2) Use WSAAsyncSelect() to place the socket in non-blocking mode and get a window message when
a connection attempt is received. Then call accept() in response.
3) Use WSAEventSelect() to place the socket in non-blocking mode and have an event signalled when
a connection attempt is received. Then call accept() in response (also requires a separate thread
to be effective).
4) Use an IO Completion Port (advanced).

*edit* Fixed some typnig.

How do you TRACE() a BSTR??

Where Name is a BSTR:
TRACE("\nFIELD[%d]: %s",j,(LPCTSTR)Name);
or
TRACE("\nFIELD[%d]: %s",j,Name);

Both just print the first char??

a BSTR is a UTF-16 (or is it UCS2? can't remember) encoded string. This means that each character is a 2 byte word. The ASCII character set fits within a single byte of each word. As such, from a char* point of view, a BSTR is basically a string with a \0 character between every character. Hence you get only the first character.

%S will work as long as you are calling an ANSI trace function. %S means "a string in the character set opposite of the current TCHAR character set". To make it work in all cases, use %ls instead.

NOTE: I am posting this message here because i dont have access to suggestion forum as i lost my email account password and for that you need to be able to log on to your mail id. So kindly accept this letter and try not to go against my appeal. If you are not agree with whatever i said and you want me to change my opinion then please email me at crook_martin2000@yahoo.co.uk and do not reply to this post here.
I apologise for any inconvenience caused to other users of this mind blowing site.
Thanks for your support.

Dear Author,
I appreciate all the efforts you took to get this site up and running but i dont like the way you have developed the forum section.
when anyone who replies to any post, then that post should come up on the top whereas new messages keep on adding and the old message goes back to 3-4 pages and most of us dont even care to look more then 2-3 pages back.
For instance look at this forum site,
http://www.nabble.com/port-xen-f12400.html
How beautifully they have managed it without making it a mess, whereas this site forum just looks a big mess.
Please take steps to change the design of this forum as we all need this great forum but would appreciate its proper use.

Thanks and Regards
Programmer
