I'm also trying to figure this out. The best I have so far is:

OFN_EXPLORER  = 0x00080000
OFN_ALLOWMULTISELECT = 0x00000200
#(...)lots of other constants

require 'swin'

filetype_filter = [['Ruby files (*.rb)','*.rb'],
['All files (*.*)', '*.*']]
paths = SWin::CommonDialog::openFilename(
nil,
filetype_filter,
OFN_ALLOWMULTISELECT,
'Choose one or more files.')
puts paths

Which looks like a horrible blast from the past: windows 3.1!
It works, but the result looks like this:
"D:\\projects\\test\\ autoit_test.rb binomial.rb"

And what if the filename contains a space? Ah yes, of course, short 
filenames.
"D:\\projects\\test\\ blum_blum_shub.rb BOYGIR~1.RB"
Another try:


paths = SWin::CommonDialog::openFilename(
nil,
filetype_filter,
OFN_EXPLORER| #<--let's try this one
OFN_ALLOWMULTISELECT,
'Choose one or more files.')
puts paths

This looks better, but it doesn't work. When multiple files are selected 
I only get the directory back, none of the files.
Help appreciated,

Siep
