win32com, COM, MediaPlayer

[Markus von Ehr]

Hi,

I am new to OLE and COM and try to play Soundfiles with the 
MediaPlayer.
The MediaPlayer doesn't appear and when I try the Play command,
I receive:

File "c:\Programme\Python\win32com\client\dynamic.py", line 207, in 
 _ApplyTypes_
 result = apply(self._oleobj_.invokeTypes, (dispid, LCID, wFlags,
retType, argTypes) + args)
pywintypes.com_error: (-21468283, 'CTL_E_ILLEGALFUNCTIONCALL', (0, None,
None, None, 0, -2146828283), None)

Does anybody know why the Player doesn't appear and why the Play 
function doesn't work? (I tried w.Play=1 but that doesn't work neither)

My Code looks like this:

# Test dynamic policy

import win32com
import pythoncom
import win32com.client

w=win32com.client.Dispatch("MediaPlayer.MediaPlayer.1")


w.AutoStart=1
w.Open("c:\Programme\Python\ex1.wav")

#w.Play()

Thanks for any comments,

Markus
