Ruby
1

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:ininitialize’
from (irb):2

Thanks,

Dan

do you have OLE/COM Object Viewer installed (I think it comes with
Visual C++).
if not, you can get it at,
http://www.microsoft.com/windows2000/techinfo/reskit/tools/existing/oleview-o.asp
http://www.microsoft.com/downloads/details.aspx?FamilyID=9d467a69-57ff-4ae7-96ee-b18c4790cffd&displaylang=en

Is “Microsoft MCI Control” listed under “Controls” or “Automation
Objects” in the
OLE/COM Object Viewer?

do you have mci32.ocx installed in System32 dir?
is mci32.ocx in your path?
is MCI.MMControl in your registry?

i think the ocx is automatically installed with Visual C++, Visual
Basic, and
other Visual Studio programs, or you can find just the control here:

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,

Dan
