1. RE: System Ping (to resolve DNS)
So Kat, I'm curious...
How do <i>you</i> resolve names to numeric IP's?

2. RE: System Ping (to resolve DNS)
Hi Mark,
Just to fill you in on euLibnet and euTCP4u ...
neither have what your looking for :(
euLibnet has "net_getpeer()" which returns the address of an open
connection, and
Tcp4u has "TcpGetRemoteID()" does the same thing (but I could never get
it to work :(.
Both of these assume you have already connected.
There was a contribution by Alexander Karpeev called
"Ping and Trace-Route" which used euTcp4u for Pings and Traces ...
it looks great ... but the include was shrouded :(
I'd personally love to see the source ... but never contacted
Alexander.

Actually, if you go to http://pages.prodigy.net/mirwalds/ you will find
tcp.ew on the page. It includes heaps.e and structs.e (both by Chris
Bensler) to handle the memory operations, but it wraps the Async versions of
both gethostbyname() and gethostbyaddr().
It does handle alot of the painfull stuff for Async lookups, and I believe
that the libs are all compatable with win32lib.
The zip file itself is here: http://pages.prodigy.net/mirwalds/tcp.zip

Can you get past this msg?:
D:\Euphoria\tcp-e\tcp_demo.exw:26
setHandler has not been declared
setHandler(getHost,w32HClick,routine_id("onClick_getHost"))
^
Warning: parameter id in onClick_getHost() is not used
Warning: parameter event in onClick_getHost() is not used
Press Enter...

dns.ew
Umm,, or dns.e , depending on where you read... but it's PatRat's (Thomas
Parslow). It's this easy:
include D:\Euphoria\DNS\dns.ew
include get.e
object junk
puts(1,dns_DNSToIP("kechara.sorcery.net"))
junk = wait_key()

Looks like you need a new version of Win32Lib. According to the list of
Win32Lib changes, it was introduced in version 0.57+. It is definetaly
faster then onClick[] and others. You can also specify multiple handlers per
event.
