Asp & COM

Hi,
Does anyboby know how can I get the returned string value from a component COM in my file .asp?
I´ve implemented a component interface like this:

HRESULT searchName([in] long userID, [out, retval] wchar_t *name)

The searchName interface must receive an userID and return a name. Is this correct?

My .asp file :
...
i = comp.searchName(100)
response.write "result = " &i&

...

And the result of this is a number and not a string .

Where are my mistakes? How should I implement this?

Thanks for any help!
