0. Thanks !
1. Try nSize *= 2 before its passing.
2. Please provide the returned value of wcstombs()

I am not sure, why you want to include chinese character in one byte char !

Are you doing everything correctly according to the description of the function[^]? Please show your code and any results that you get.

Here is my code: BSTR key = _T("インフォメーション"); char *szDataIn; CString str = key ; int nSize = str.GetLength(); szDataIn = new char[nSize+1]; memset(szDataIn,0,nSize+1); wcstombs(szDataIn, str, nSize+1); Here szDataIn consists of empty value

Looking at your code I would suggest that your output buffer (szDataIn) is not long enough for the converted string. Take a look at the MSDN link I gave you and use the function to find the required size of your resulting MBCS buffer.

Here I used variable nSize which is the length of the string and it is 9.So i gave the third parameter as nSize+1

Please read again the link I gave you, particularly the section on how to find the required length of your output buffer.
