Posting the code would help a lot.

No idea on what you are talking of! Just in case you don't know, we are not magicians and mind readers.

That isn't C code. Please change the question tag.

Solution 2

This Regular Expression matched almost everything (if limits the matches at all). Hard to say what was your idea, but URL validation usually looks simpler.

This is a collection of Regular Expressions on the URL validations topics: http://regexlib.com/Search.aspx?k=URL[^].

Do any of them do what you need?

Thanks im just trying to get the url from thhe current packet

Sergey Alexandrovich Kryukov 10-Apr-11 20:56pm

This is a different problem; it does not require validation.
How about URL validation using Regex, is your problem solved?

Helpful link with lots of variations, 5'd

Sergey Alexandrovich Kryukov 10-Apr-11 15:40pm

Thank you, Wika.
May be, too many variations, but for OP it would be good to understand the ideas people have on this topic.

I'm not looking to validate an URL, I justwant to get the URL from a packet that is urrentl downlowding as well as thepacket ID. I'm sorry I'm new to this, so excuse me if I'm grabbing at straws.
Thank You. DS

Sergey Alexandrovich Kryukov 11-Apr-11 14:09pm

I already say, it's in your code. Why would you do Regex at all then?
You should have asked a different question. You code is an attempt to do validation and nothing else. How could you expect any help on completely different question, by reading your mind?

Member 7766180 11-Apr-11 14:30pm

Like I said I'm new. Any help or guidance is appreciated. You said it's in my code. Could you kindly explain where. Thank you.
DS

Sergey Alexandrovich Kryukov 11-Apr-11 14:40pm

Sorry, I don't see you question: what can I explain?

Member 7766180 11-Apr-11 15:18pm

What I'm trying to do is grab the URL from a packet and save the URL and packet ID as a variable. Thank you, I appreciate the help.
