Have you tried WideCharToMultiByte() ?

well sorry it's so simple to convert it

just I used this code

USES_CONVERSION;

lpwstr wchar = T2W(bstrvar);

;)

lpwstr wchar = T2W(bstrvar);
That's an ATL macro.

Here's a quote from Microsoft:
Note The recommended way of converting to and from BSTR strings is to use the CComBSTR class. To convert to a BSTR, pass the existing string to the constructor of CComBSTR. To convert from a BSTR, use COLE2[C]DestinationType[EX], such as COLE2T.
That is, do not use the macros.
