Hi

I have a problem with the following
    std::string stmp = "PORT (127,0,0,1,6,56)\r";
    cout << stmp << endl;
    boost::regex 
regex_ip(".+\\(([0-9]{1,}),([0-9]{1,}),([0-9]{1,}),([0-9]{1,}),([0-9]{1,}),([0-9]{1,})\\).*");

    std::string sip = boost::regex_replace(stmp, regex_ip, "$1.$2.$3.$4", 
boost::format_all);

    output is 127.0.0.1
    if I change to this stmp = "PORT 127,0,0,1,6,56\r";// remove the '(' 
and' )'
    the output is 127,0,0,1
what do I have to change in the boost::regex regex_ip to get 127.0.0.1 dots 
instead of comma

appreciate any help
Christer
