Hi Christopher,
Thanks for responding. Forgot to mention that I did test this with
FILE_GENERIC_WRITE also but the result is the same. If this
is applied on a folder it leaves the folder unopenable. If it's applied on
a file(say a.txt file), Notepad shows warning informing "Access Denied" but
can be edited and can be saved in a different location.
FYI I'm using Python 3.2 with Pywin32 ver 219.
Thanks,
Jeba
