Subject: Drag and Drop in Windows with Explorer

I need to make a Windows program with RXRuby that batch processes audio
files, after the user drags them from Explorer to the program's window.

This works easily in Linux, I just accept "text/uri-list".  I was trying
to find the Windows equivalent, so I wrote some code to list the offered
types, which also works great in Linux.  But in Windows (I tried XP and
98SE), when dragging files from Explorer, I don't even get a
SEL_DND_MOTION.  My code is attached.

Is it possible to get dropped files in Windows, and if so, how?

Thanks,
