[ Windows | MFC ] easy way to convert string between UNICODE <-> ANSI

easy way to convert between UNICODE <-> ANSI (wchar_t* <-> char*);

simply use CStringA & CStringW;

>>

char* char_ansi="ansi";

CStringA cs_ansi(char_ansi);

wchar_t* char_unicode=_T("unicode");

CStringW cs_unicode(char_unicode);

than run function below.

CStringA Utility::convertCStringW2A(CStringW wString)

{

     CStringA aString = CW2A(wString);

     return aString;

}

CStringW Utility::convertCStringA2W(CStringA aString)

{

     return wString;
