Have you tried WideCharToMulti Byte() ?

well sorry it's so simple to convert it

just I used this code

USES_CONVERSION ;

lpwstr wchar = T2W(bstrvar);

;)

[weaknessforcats]

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.
