Boost库被称为C++的准标准库，功能非常强大，最近准备学习这个库。下面是一个示例程序

// ProtocolBufferTEST.cpp 
//
#include "stdafx.h"
#include <iostream>
#include <boost\lexical_cast.hpp>
#include <boost\asio.hpp>

//test type cast with boost
void TEST_LeCast()
{
	using boost::lexical_cast;

	int a = lexical_cast<int>("123");
	double b = lexical_cast<double>("123.0123456789");
	std::string s0 = lexical_cast<std::string>(a);
	std::string s1 = lexical_cast<std::string>(b);
	std::cout << "number: " << a << "  " << b << std::endl;
	std::cout << "string: " << s0 << "  " << s1 << std::endl;
	int c = 0;
	try{
		c = lexical_cast<int>("abcd");
	}
	catch (boost::bad_lexical_cast& e){
		std::cout << e.what() << std::endl;
	}
}

#include <boost/date_time/posix_time/posix_time.hpp>
using namespace std;
using namespace boost;
using namespace boost::
