Using COM library

[ldarrambide]

Hi Gintaras, hi all

I have a program name dbPoweramp that registers a COM library named DMCSCRIPTINGLib (found in COM librairies menu)

In right pane, i find this

--- Coclasses ---
Converter
WaveSettings
Mp3Settings
OggSettings
WMASettings

--- Interfaces ---
IConverter
IWaveSettings
IMp3Settings
IOggSettings
IWMASettings


I registered it, got this line

typelib DMCSCRIPTINGLib {E0F7789A-88C0-450B-AD6C-A7EB6D227127} 1.0

i try to use it::

DMCSCRIPTINGLib.IConverter k._create

at runtime, i have an error message


0x80040154, Unregistered class

How to use it???
