Re: Vista won't show file version

The files in question are actually DLLs, with different extensions. In XP,
Windows interpreted the file version fine, but Vista doesn't want to. Do we
need to write a DLL that knows how to open that filetype and read the
properties? Can you give me any useful links explaining this?

Thanks.

I would think that investigating IPropertyStore on MSDN would lead you in
the right direction. Additionally, Ben --
http://blogs.msdn.com/benkaras/ -- has written a fair amount about property
handlers for "custom" file types.

As re: reusing existing PropertyHandlers for your own private type -- I'm
not aware of the internals of that code, so couldn't speak to it.

This is definitely not an area of my expertise, but -- hopefully this
propels you along in the right direction.
