These constants are defined in the 'commctrl' module:

Type "help", "copyright", "credits" or "license" for more information.
>>> import commctrl
>>> commctrl
<module 'commctrl' from 'C:\Python23\lib\site-packages\win32\lib\commctrl.pyc'>
>>> commctrl.LVM_GETITEMCOUNT
4100
>>> commctrl.TCM_GETITEMCOUNT
