如何使用MFC CString與提升字符串算法庫

Question

備註：string_algo工作得很好std::wstring，當然我可以（並且）將CString對象轉換爲std :: wstring first if當我需要一個來自string_algo的算法。這將是非常好的，但如果我可以放入CString對象 - 與現有代碼的集成將會更容易！

我想做什麼：

CString in = ...; 
const CString out = boost::replace_last_copy(in, L"SEARCH", L"REPLACE"); 

由於suggested here我想還包括boost/range/mfc.hpp有Boost.Range adapted to MFC。 （雖然我不完全得到this header因爲看它似乎並不爲CString的做任何事情，只爲集合類。）

升壓1.44.0與Visual Studio 2005

測試代碼如下像這樣：

#include "stdafx.h" 
#include <iostream> 
#include <boost/range/mfc.hpp> 
#include <boost/algorithm/string.hpp> 

void f(CString const& input) { 
    CString out = boost::replace_last_copy(input, L"FROM", L"TO"); 
    std::wcout << out << "\n"; 
} 

我得到看起來像這樣的錯誤：

Answer 1

嘗試用CStringW更換CString，在C映射到CStringA。

確切的錯誤代碼，標題中的哪一行呢？你可以嘗試在本地代碼中替換相同的錯誤嗎？
