Hi,

How can I get an std::string (not std::wstring) out of a BSTR? I need to
convert a BSTR to single byte encoding.

Thanks

You can convert a BSTR to a char* with WideCharToMultiByte and initialize
the std::string from there. Just keep in mind that in many environments
(including VB) a NULL BSTR and an zero length BSTR are equivalent.

If you don't mind using the COM "helpers" in VC, you can also use _bstr_t
which has a char* operator that does the conversion for you (typed in email,
so not checked):

std::string bstr2std(_bstr_t b)
{
char* c = b;
if (b)
return c;
else
return "";
}
