Hi all,

Windows XP, SP2
Ruby 1.8.2 and 1.8.4

Why does this fail?

irb(main):001:0> require "win32ole"
=> true
irb(main):002:0> sound = WIN32OLE.new("MCI.MMControl")
WIN32OLERuntimeError: unknown OLE server: `MCI.MMControl'
HRESULT error code:0x800401f3
Invalid class string
from (irb):2:in `initialize'
from (irb):2

Thanks,

Dan

I don't see it.

Nope. Closest thing I've got is mciole32.dll. Where do you get it?
I'm on Windows XP Pro, SP2 with the MS SDK and .NET stuff (cl 13).

Thanks,
