How can I modify the user rigths on a xml file?

[Rainer Queck]

Hello NG,

How can I modify the user rigths on a xml file?
Can this be done by code as well?

I could only find the possibillity to modify user rights on folders, not on
files and this onyl manual.

Hi Michael,

thanks for the link! That should make it fairly easy :-)

Don't use this method if you have access to V2 of the framework, use the
System.Security.AccessControl
namespace classes instead.
Also keep in mind that changing the security settings on Filesystem objects
(and others) requires administrative privileges, your applications don't
require to run as administrator do they?

Hi Rainer,

Thank you for the feedback.

Is your code using .Net1.1 or 2.0?

The code snippet link provided by "Michael Nemtsev" leverages the
gotdotnet code sample. The gotdotnet code sample is provided to address the
lack of file security support in .Net1.1. In .Net2.0, we have added the
build-in support for configuring the security setting for directories and
files. That's why Willy suggested you to use the build-in
System.Security.AccessControl namespace for your task if you are using
Net2.0.

In .Net2.0, setting the user rights on a file is pretty straightforward.
You may use File.GetAccessControl() to obtain the current security setting
of the file as a FileSecurity object. Then, you may use
FileSecurity.AddAccessRule() and FileSecurity.RemoveAccessRule() methods to
add or remove rules from the FileSecurity object. Finally, you can use
File.SetAccessControl() method to assign the new FileSecurity to the file.

There is sample code snippet in the link below:

Hope this helps.

Thank you very much for the additional information and link!
I think this makes it very easy now, to implement to my project, what I am
looking for. I am currently thinking to add functionallity, that allows a
user of my app (if he knows the admin access passwords) to readjust the user
rights of the xml-file in question. This might become necessary, because it
is possible, that this file can be moved around different systems since it
holds setup data to a external teststand.

;-)
No they don't...
....but currently I am thinking about adding a feature that would allow the
user in a case like this to readjust the file rights if necessary.
