[python-win32] How to set value with PyIPropertyStore

[Peng Chen]

Hi Tim,
 Thanks for the reply. Sorry for the late. I just found your email today.
Yes I tried with this code:

from win32comext.propsys import propsys, pscon
VIDEO_DATE_ENCODED = pscon.PKEY_Media_DateEncoded
properties = propsys.SHGetPropertyStoreFromParsingName(file_name)
mDate = properties.GetValue(VIDEO_DATE_ENCODED).GetValue() # got the
datetime object
dateShifted = mDate + shift_time.timedelta_obj # shift date
properties.SetValue(VIDEO_DATE_ENCODED, dateShifted) # set value
properties.Commit()

and I got error message when executing to
properties.SetValue(VIDEO_DATE_ENCODED, dateShifted)

it reports:
Object must be a PyPROPVARIANT
