Ruby scripting -- missing members

[djlewis]

I'm trying this in Ruby, which is new in two ways -- Ruby is new to me, and I can't find anybody else who's discussed connecting Ruby to dMC publicly.

It seems to go OK for dMCScripting.Converter, but the other subobjects
come up empty -- they are there, but I can't see or use any of the
members. Here's code to show the problem (should be able to grok it without knowing Ruby)...

require 'win32ole'

cnv = WIN32OLE::new("dMCScripting.Converter")
mp3 = WIN32OLE::new("dMCScripting.Mp3Settings")
ogg = WIN32OLE::new("dMCScripting.OggSettings")
wav = WIN32OLE::new("dMCScripting.WaveSettings")
wma = WIN32OLE::new("dMCScripting.WMASettings")

p = Hash.new
p[ :cnv] = cnv.ole_get_methods
p[ :mp3] = mp3.ole_get_methods
p[ :ogg] = ogg.ole_get_methods
p[ :wav] = wav.ole_get_methods
p[ :wma] = wma.ole_get_methods

p.each do |k, v|
printf( "%s, %d members\n", k, v.size)
v.each {|x| printf( " %s\n", x.to_s)}
end

printf( "dMCScripting.Converters.VolumeNormalize = %d\n", cnv.VolumeNormalize)
printf( "dMCScripting.Mp3Settings.Frequency = %d\n", mp3.Frequency)

------------------

wav, 0 members
wma, 0 members
cnv, 7 members
VolumeNormalize
PreserveTags
DeleteSourceFiles
ConvertToFolder
ToFolder
GetCompressions
WasConvError
mp3, 0 members
ogg, 0 members
dMCScripting.Converters.VolumeNormalize = 0

dbPowerAmp2.rb:24:in `method_missing': unknown property or method
`Frequency' (WIN32OLERuntimeError)
HRESULT error code:0x80020006
Unknown name. from dbPowerAmp2.rb:24

--------------------
Could this could be a subtle problem with the dMC dll? A Ruby bug? Lots of people are using a variety of automation hosts with the WIN32OLE library.

I can't see what I could be doing wrong, since it works for one sub-object but not for others. Changing the order of things does not help, BTW -- dMCScripting.Conversion always works and the others come up without their members. Also, note that sticking a totally non-existent sub-object in there generates an error on the call to WIN32OLE::new. The fact that it works for the others means that WIN32OLE is indeed finding them, but they are appearing as empty.
