Hi,
I'm a newbie on boost.
I've downloaded and used some features.
I couldn't find how to cast uuid into string.
#include "boost/date_time/gregorian/gregorian.hpp"
#include 
#include 
#include 
#include 
...
date GeneratorUtils::getRandomDate() {
int year, month ,day;
day = rand() % 30;
month = rand() % 12;
year = 1980 + rand() % 25;
string str_date = "" + day + month + year ;
date d(from_simple_string(str_date));
return d;
string GeneratorUtils::getRandomID(){
random_generator gen;
uuid u = gen();
return u.uuid_to_string(); // ERROR
}
It does not accept any to_string() function. Is there a way to convert
from uuid to string in C++?
(by the way, I can use the other things such as date d, uuid u etc.)
see
http://www.boost.org/doc/libs/1_43_0/libs/uuid/uuid.html#boost/uuid/uuid_io....
one can also use lexical_cast eg:
uuid u;
string s = lexical_cast<string>(u);
I'll update the documentation to include this example.
By the way. Andy, do you plan to implement to_string() member-function 
or standalone function? AFAIK lexical_cast has a lot of overhead :(
