1. Get IP Address with tcp.ew? Today?!
Please, for the love of all that's good and holy...
can somebody provide a routine whereby I can get the
PC's IP address? I don't understand Robert Szalay's
example MyIPAddr.exw, although it does what I need! :)
Thanks.

Have you tried using the tcp_gethostbyname function? It seems that you
might want to call as:
sequence wrk_seq
wrk_seq = tcp_gethostbyname(mywindow, "localhost")
Or am I missing something?

Doing that, wrk_seq is set to 1.

Yep, that's right.
You'll either get a number > 0 or a -1 (-1 being an error). In your
Win app you'll need to have an event handler to catch the WM_HOSTINFO
message. Once you get that message you'll call tcp_host_info()
passing the returned valued from tcp_gethostbyname. You'll get back
(if everything works) a sequence of two elements, the first being the
ip address and the second being the host name.
You can cancel the host name lookup by calling tcp_cancel_lookup passing
the value returned from tcp_gethostbyname. Take a look at the example.txt
that comes with the tcp.ew .zip.

Jonas, thanks for the help! I don't want to have to
do the event handler for WM_HOSTINFO. I don't get that. How
will it fit into my program? I think I'll just run "ipconfig"
and parse the output! :)

You could use TCP4U as below.. (works for me..)
sequence ip, Actual_Addr
ip = tcp4u_get_local_id()
Actual_Addr = sprintf( "%s", {ip[tcp4u_host_id]} )
