    win32com.client.GetActiveObject()

    Hi,

    I have been successfully using iTunes' COM interface with Python
    using either of the following lines successfully:

    iTunes = win32com.client .gencache.Ensur eDispatch("iTun es.Application" )
    iTunes = win32com.client .Dispatch("iTun es.Application" )

    The only problem is that it will launch iTunes if it is not running
    by instantiating the object here. There are some reasons why I have
    not attempted to use more COM to check if iTunes is an active
    process, I tried either of the following lines to only form a
    connection if iTunes is running.

    iTunes = win32com.client .GetActiveObjec t("iTunes.Appli cation")
    iTunes = win32com.client .GetObject(Clas s = "iTunes.Applica tion")

    Both lines result in a pythoncom.com_e rror with 'Operation
    unavailable' in the second element of the tuple. Has anyone been able
    to successfully do this with iTunes' COM server? I have seen other
    'Operation unavailable' messages in a few other mailing lists but was
    unable to find any solutions to this problem.

    Regards,
    David

      Re: win32com.client .GetActiveObjec t()

      Basically, this means the application doesn't register itself
      with the Running Object Table. There's not much you can
      do about it, except maybe petition whoever makes ITunes.
