If you're doing managed programming (ie, using C++/CLI and the .NET
framework), there is regular expression support in the framework.

If you're doing native coding, there is a regex engine in ATL server :
see http://msdn2.microsoft.com/en-us/library/wzck77h4(VS.80).aspx
Anyway, I would rather recommend to use boost...

Try http://www.pcre.org/ -- Perl Compatible Regular
Expressions. It's available with full source code, and has a BSD
license (making it quite easy to distribute with any of your apps).
It's been used in a lot of well-known software projects. It'd probably
be easier to integrate than boost.

Hi Cholo Lennon!

i found these line of code for using regular expression in VC, please
guide me, Is this right to use it or use some other API for the
regular expression??

Code is:

#include <atlrx.h>

CAtlRegExp<> re;
re.Parse(TEXT("\\w+([-+.']\\w+)*@\\w+([-.]\\w+)*\\.\\w+([-.]\\w+)*"));
CAtlREMatchContext<> mc;
if(!re.Match(singleEmail, &mc))
{
retStatus = FALSE;
break;
}

Those lines use ATL server library (check Arnaud response). In general all regex libraries use the same concepts so it's easy to
port those code to other libraries.
ATL server is part of VC 7 (or above) so it's fine to use it. If you want portability to other plattforms you can use boost
libraries (http://www.boost.org/libs/regex/doc/index.html) or like Nathan Mates said, Perl Compatible Regular Expressions.
