MFC编程中与编码方式有关的宏定义的使用

1

多字节字符集:char *strcpy(char *strDestination, const char *strSource);

Unicode字符集:wchar_t *wcscpy(wchar_t *strDestination, const wchar_t *strSource);

通用:_tcscpy

#ifdef  UNICODE   
    #define _tcscpy       wcscpy  
#else  
    #define _tcscpy       strcpy  
#endif

2

CString String2CString(std::string str)
{

CString cstr;
cstr = CA2T(str.c_str());//CA2T是与编码方式有关的宏定义
return cstr;
}

std::string CString2String(CString cstr)
{
std::string str;
str = CT2A(cstr.GetString());//CT2A是与编码方式有关的宏定义
return str;
}

3

#ifdef  UNICODE   
    #define _ttoi       _wtoi
#else  
    #define _ttoi       atoi
#endif

4
#ifdef  UNICODE   
    #define _stprintf       _swprintf
#else  
    #define _stprintf       sprintf
#endif

5

#ifdef  UNICODE   
    #define _tcslen       wcslen
#else  
    #define _tcslen       strlen
#endif
