 Posted: Mon Aug 25, 2003 8:28 am Post subject: Retrieving access rights to a directory. |
 |
|
I've been twisting my mind to figure out a good way to get the access rights
to a directory.
I need to find out if:
1. The directory given can be read (ie. read access)
2. The directory given can be written to (ie. write access).
I guess 1 is trivial, just try to list it's contents. I guess this will work
with populated directories but what if the directory is empty?
# 2 could be solved by trying to create an empty file and then delete it
(catching any IO errors in the progress). However, this will be a problem if
you have write access but not delete access.
Any tips/pointers will be greatly appreciated.
Best regards,
Tom Reiertsen,
Reiertsen Software Systems.

The Platform SDK documentation has some sample code for this. It's written
in C, but should be translatable:
ms-help://MS.PSDK.1033/security/security/searching_for_a_sid_in_an_access_token.htm

There are free classes available on my website that will do this. Go
for the 'NT Low Level Utilities' package. They work on NT4, W2K & XP...
