[python-win32] Python win32com and iTunes

[Test Drive]

Hi All,

I am trying to use win32com with iTunes (version 7.0.1.8). However it seems
like I am missing something and I am clueless about that.

<code>
import win32com.client as wc
import pythoncom,sys

app=wc.Dispatch('iTunes.Application')
mainPl=app.LibraryPlaylist

print ">>>>>>>>>>>>>> Dir <<<<<<<<<<<<<<<<<<"
print dir(mainPl)

print ">>>>>>>>>>>>> Help On PlayFirstTrack <<<<<<<<<<<<<"
print help(mainPl.PlayFirstTrack)

mainPl.PlayFirstTrack()
sys.exit(-1)
</code>

<output>
C:\Python24\MyScripts>python iTunesmin.py

I am clueless about the error. Same thing happens when I use the code posted
here (http://www.brunningonline.net/simon/blog/archives/001627.html) under
the title "Driving iTunes from Python on Windows".

Any help is appriciated.
