1.字符转换

1、将单字节Char转化为双字节的wchar_t的转换函数

 

wchar_t* c2w(const char *str)
{
     int length = strlen(str)+1;
     wchar_t *t = (wchar_t*)malloc(sizeof(wchar_t)*length);
     memset(t,0,length*sizeof(wchar_t));
     MultiByteToWideChar(CP_ACP,0,str,strlen(str),t,length);
     return t;
}

 

//将单字节char*转化为宽字节wchar_t*
wchar_t* AnsiToUnicode( const char* szStr )
{
        int nLen = MultiByteToWideChar( CP_ACP, MB_PRECOMPOSED, szStr, -1, NULL, 0 );
        if (nLen == 0)
        {
             return NULL;
        }
        wchar_t* pResult = new wchar_t[nLen];
        MultiByteToWideChar( CP_ACP, MB_PRECOMPOSED, szStr, -1, pResult, nLen );
        return pResult;
}

//将宽字节wchar_t*转化为单字节char*
inline char* UnicodeToAnsi( const wchar_t* szStr )
{
       int nLen = WideCharToMultiByte( CP_ACP, 0, szStr, -1, NULL, 0, NULL, NULL );
       if (nLen == 0)
       { 
            return NULL;
       }
       char* pResult = new char[nLen];
       WideCharToMultiByte( CP_ACP, 0, szStr, -1, pResult, nLen, NULL, NULL );
       return pResult;
}

 

2、char[] 转换为 LPWSTR

   解决方案:

   思路一:
 使用CA2W字符转换宏(ATL and MFC String Conversion Macros)。
        根据MSDN描述,这个宏用于将ANSI转换为Wide Character(UNICODE)

     代码如下:
        LPWSTR   aaa   =   CA2W(text);
        item.pszText = aaa;

   思路二:
 使用int MultiByteToWideChar()函数。根据MSDN描述,这个方法:This
 function maps a character string to a wide-character (Unicode)
 string。

     代码如下:

        TCHAR aaa[31];
        MultiByteToWideChar(0,0,text,31,aaa,62);
