How to eject CD using WMI and Python?

Question

Using Windows\' WMI library, how can I eject CD rom mounted in a specific CD/DVD drive?

I am asking for sources from WMI docs or examples since I am using wmi.py library

Answer 1

You can use ctypes.

import ctypes

ctypes.windll.WINMM.mciSendStringW(u"set cdaudio door open", None, 0, None)

UPDATE:

If you have more that one drive, you can use to open command to initialize a specific device before calling the function above. For example (not tested).

ctypes.windll.WINMM.mciSendStringW(u"open D: type cdaudio alias d_drive", None, 0, None)
ctypes.windll.WINMM.mciSendStringW(u"set d_drive door open", None, 0, None)

Also, see the documentation on how to check return values
