可是始终觉得在数据库里写触发器会使得程序不够灵活，不方便配置等，就百度搜如何用c++来实现。后来确实搜到不少资料，但大多都是在控制台下的程序。后来王广同学再次发挥了不怕苦，不怕累的精神，把其转为MFC下的了，写了个小类，用起来非常方便，具体如下：

HzToPy.h

#pragma once

class CHzToPy
{
public:
 CHzToPy(void);
 ~CHzToPy(void);
 char convert(wchar_t n);
 bool In(wchar_t start, wchar_t end, wchar_t code);
 CString HzToPinYin(CString str);
 CString PinYin;
};

HzToPy.cpp

#include “StdAfx.h”
#include “HzToPy.h”
#include <string>

CHzToPy::CHzToPy(void)
: PinYin(_T(“”))
{
}

CHzToPy::~CHzToPy(void)
{
}

char CHzToPy::convert(wchar_t n)
{
 if   (In(0xB0A1,0xB0C4,n))   return   ‘a’;
 if   (In(0XB0C5,0XB2C0,n))   return   ‘b’;
 if   (In(0xB2C1,0xB4ED,n))   return   ‘c’;
 if   (In(0xB4EE,0xB6E9,n))   return   ‘d’;
 if   (In(0xB6EA,0xB7A1,n))   return   ‘e’;
 if   (In(0xB7A2,0xB8c0,n))   return   ‘f’;
 if   (In(0xB8C1,0xB9FD,n))   return   ‘g’;
 if   (In(0xB9FE,0xBBF6,n))   return   ‘h’;
 if   (In(0xBBF7,0xBFA5,n))   return   ‘j’;
 if   (In(0xBFA6,0xC0AB,n))   return   ‘k’;
 if   (In(0xC0AC,0xC2E7,n))   return   ‘l’;
 if   (In(0xC2E8,0xC4C2,n))   return   ‘m’;
 if   (In(0xC4C3,0xC5B5,n))   return   ‘n’;
 if   (In(0xC5B6,0xC5BD,n))   return   ‘o’;
 if   (In(0xC5BE,0xC6D9,n))   return   ‘p’;
 if   (In(0xC6DA,0xC8BA,n))   return   ‘q’;
 if   (In(0xC8BB,0xC8F5,n))   return   ‘r’;
 if   (In(0xC8F6,0xCBF0,n))   return   ’s’;
 if   (In(0xCBFA,0xCDD9,n))   return   ‘t’;
 if   (In(0xCDDA,0xCEF3,n))   return   ‘w’;
 if   (In(0xCEF4,0xD188,n))   return   ‘x’;
 if   (In(0xD1B9,0xD4D0,n))   return   ‘y’;
 if   (In(0xD4D1,0xD7F9,n))   return   ‘z’;
 return   ‘\0′;
}

bool CHzToPy::In(wchar_t start, wchar_t end, wchar_t code)
{
 if   (code   >=   start   &&   code   <=   end)
 {
  return   true;
 }
 return   false;
}

CString CHzToPy::HzToPinYin(CString str)
{
 //std::string   sChinese   =   “张三丰”;   //   输入的字符串
#ifdef UNICODE
 DWORD dwNum = WideCharToMultiByte(CP_OEMCP, NULL, str.GetBuffer(0), -1, NULL, 0, NULL, FALSE);
 char *psText;
 psText = new char[dwNum];
 if (!psText)
  delete []psText;
 WideCharToMultiByte(CP_OEMCP, NULL, str.GetBuffer(0), -1, psText, dwNum, NULL, FALSE);
#endif
std::string   sChinese=psText;
 char c;
 char   chr[3];
 wchar_t   wchr   =   0;
 int len=sChinese.length()/2;
 char*   buff   =   new   char[len];
 memset(buff,   0×00,   sizeof(char)*sChinese.length()/2+1);

 for   (int   i   =   0,   j   =   0;   i   <   (sChinese.length()/2);   ++i)
 {
  memset(chr,   0×00,   sizeof(chr));
  chr[0]   =   sChinese[j++];
  chr[1]   =   sChinese[j++];
  chr[2]   =   ‘\0′;

  //   单个字符的编码   如：’我’   =   0xced2
  wchr   =   0;
  wchr   =   (chr[0]   &   0xff)   <<   8;
  wchr   |=   (chr[1]   &   0xff);

  buff[i]   =   convert(wchr);
 }
 PinYin=buff;
 return  PinYin;
}

 然后在MFC中使用到该类的文件中，首先写上include “hztopy.h”,然后如下：

CHzToPy test;
CString abc=_T(“刘德华”);
CString msg=test.HzToPinYin(abc);
MessageBox(msg);
