I have the following code:
Dim IP, domainName As String
domainName = "yahoo.com"
Try
IP = System.Net.Dns. GetHostByName(d omainName).Addr essList(0).ToSt ring()
Catch ex As Exception
IP = "Not Valid"
End Try
Console.WriteLi ne(IP)
System.Threadin g.Thread.Sleep( 2000)
When it has a resolvable domain, like yahoo.com it responds back instantly
with the ip address. However, if there is a domain in there that does not
exist, like blue2343.com, it takes upwards of 5 seconds to print "Not Valid"
to the screen. Why is that? and is there a way around it?
Thanks,
Scott

Scot,
Not the first time I've seen something like this. I've actually had code
that would throw exceptions when just running through it, but when I stepped
through it, would work just fine! It stinks to say it, but rebooting often
helped that problem (not that it actually occurred on a regular basis). I'm
afraid I have no more advice on the subject, and I hate to leave you with
"Maybe you'll have to live with it", so hopefully someone else will have a
good suggestion.
Sorry I couldn't be of more help,

Nothing seems to take the 5 seconds, even when I rapidly go through it

line and click set breakpoint). When you run the app it will stop there, and
then hit F11 to step into the code line by line and you will see where
the hic-cup is occurring.
No problem, Raymond. I'll figure something out. Thanks for trying.

Hi,
I'm trying to write the function below and have it working, but I
benchmarked it against strcmp() and its much slower. My test is to compare 2
strings that are identitical 100,000,000 times. Yeah, thats a lot, but I
needed to scale up the test to get a real timing on the function. The weird
thing is, even when I comment out almost the entire function, its still much
slower then strcmp()... at full implementation, strcmp() takes 5...
