I don't understand this patch at all ...

     strcpy(lpfd->cAlternateFileName, "msms001.vwp");
-    return (HANDLE)-1;
+    return (HANDLE)0;
 }

I would think this means previous was HANDLE-1 as (HANDLE) is resolved to 
HANDLE.

But I don't understand the new one ...

I would think: (HANDLE) is resolved to HANDLE and then multiplicated by 0 ?!

hm, or is it resolved to HANDLE0 but what then ?

Or is it a syntax that in previous: if HANDLE is NULL -1 is returned ...

And now if HANDLE is NULL 0 is returned ? Hm, but then 0 would be superfluous 
...

I'm really confused as I haven't seen such syntax before and couldn't find an 
answer in my books ...
