It's a request from a customer. I think this
is Mac thing that for this application should
work on Windows, too.

To stick to the analogy I used, this would
be as if at run-time MS Word would create an
icon on the desktop which, when .doc files
are dumped on it, spell-checks them in the
language specified when the user ordered
Word to create the icon.
It is important that the user can create
these droplets at run-time of the app, from
a dialog within the app that specifies the
settings (language) to be used.

Yes, but Word would just open any files
dumped onto it.

No. At run-time. :)

OK, I see. Thanks.

The problem is, that instead of just a string
(language), there is fairly large settings to
be passed. Also, this settings should not be
somehwere else, because they are supposed to
be copied when the icon is copied (like to
another machine).
But I suppose I could create a small .exe file
that has the settings in its resources. Those
can be changed at run-time.
So what I would do at run-time is to take the
template .exe file, copy it to the desktop,
give it a user-supllied name, and modify its
resources with the settings given.

Well, I guess its me who has to thank you! :)
You got me started on this.
