Question

I need to write some code for a MFC project, but I don’t know how to get required code to work when using MFC.

I prototyped my function first just using the STL types, and boost.

STL Prototype

#include <string>
#include <boost/algorithm/string/classification.hpp>
#include <boost/algorithm/string/find.hpp>

void ProtoTest()
{
    std::string sText("123Hello4");
    boost::iterator_range<std::string::iterator> nc_result = find_token(sText, boost::algorithm::is_alpha(), boost::algorithm ::token_compress_on);
}

Result = “Hello”

I eventually managed to get it working with MFC, however I had to supply two typedefs. I would like to do it in one, however there isn’t much documentation on using the MFC port provided in boost.

#include "stdafx.h"
#include <boost\range\atl.hpp>

void Test()
{
    typedef boost::range_iterator<CString>::type CString_it;
    typedef boost::iterator_range<CString_it> CString_range;
    CString strText("123Hello4");
    CString_range r;
    r = find_token(text, boost::algorithm::is_alpha(), boost::algorithm ::token_compress_on);
}

Again Result = “Hello”

Is there a single typedef I can use to hold the result of find_token, rather than needing two typdefs to achieve it.

Answer 1

You could just combine them

typedef boost::iterator_range<boost::range_iterator<CString>::type> CString_range;

But I don’t know if that is an advantage.
