Cast _TCHAR* to BSTR

I'm very new to this. I have a parameter coming into the command line arguments of a console application that is defined as "_TCHAR* argv[]". I want to convert the value to a "BSTR". I've tried "BSTR _Temp = SysAllocString(argv[1])". This does not work. I know I'm missing a lot, so any help would be appreciated

Thanks.
 
Hi,

If you use BSTR , why don't you choose CComBSTR. It's a wrapper on BSTR and
provides much more functionaliltiy.

And I think one of the constructor takes TCHAR, which I assume you
understand, in MBCS, it means char, and in UNICODE, it means WCHAR.

J.W.

Hi Marius,

SysAllocString(argv[1])".

If your main(...) function is not a wmain(...) type, how about use the
following conversion directly:
BSTR _Temp = SysAllocString((OLECHAR *)argv[1]);


Thanks!
