No application crash,
the only changes is in
std::string stmp = "PORT (127,0,0,1,6,56)\r"; this works with
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",
out 127.0.0.1
to
std::string stmp = "PORT 127,0,0,1,6,56\r"; this not.
out PORT (127,0,0,1,6,56)
if i change to
boost::regex regex_ip(".+\([0-9]{1,}),([0-9]{1,}),([0-9]{1,}),([0-9]{1,}),([0-9]{1,}),([0-9]{1,})\.*");
the out is
7.0.0.1

I must change something in the regex_ip but i cant figure it out.

  I am not an expert in Regex but try to substitute the commas between the parenthesis by \. (backslash dot), escaping the dot.

  regex_ip(".+\\(([0-9]{1,})\.([0-9]{1,})\.([0-9]{1,})\.([0-9]{1,})\.([0-9]{1,})\.([0-9]{1,})\\).*");

  Note: I have not tested it.

  Hope this helps,
  Mau.

    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
