How to programmatically modify the users full control

Dear,

Forgive me, if I have posted in wrong forum. Please point me to the correct forum for my enquiry below.

As we are updating our program and installer to support Vista, we need to programmatically modify the windows folder's Users rights. For example:

- We created a folder under "C:\ProgramData\Test\" and store some files which our program need to update when it runs.
- Works fine in Administrator mode.
- In Standard user mode it does not work as the folder does not have the full rights.

If we go to administrator account, select the above folder, right click to select Properties, Security tab, select Users and apply 'Full control' then works fine in standard user.

Can we set the Users full controls programmatically? Is there any other approach?

Thanks in advance.

Dear,

I am trying to give full rights to a folder in Vista so my program can modify the files in the folder in Admin/Standard user mode.

The folder I am creating is under "C:\ProgramData" folder. The code below execute without any error but the "Users" account don't get the full rights.

Thanks in advance for looking at my post and your expert advice.

==============================================================
using System.IO;
using System.Security.Principal;
using System.Security.AccessControl;


static void Main(string[] args)
{
string folderPath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData), "Test_folder");

if (!Directory.Exists(folderPath))
Directory.CreateDirectory(folderPath);

UpdateAccountRightrs(folderPath);

Console.ReadLine();
}



/// <summary>
/// Iterate each account and update rights
/// </summary>
/// <param name="folderPath"></param>
private static void UpdateAccountRightrs(string folderPath)
{
Console.WriteLine("-> UpdateAccountRightrs() folderPath: " + folderPath);

FileSecurity security = File.GetAccessControl(folderPath);
AuthorizationRuleCollection acl = security.GetAccessRules(true, true,
typeof(System.Security.Principal.NTAccount));

foreach (FileSystemAccessRule ace in acl)
{
string accountName = ace.IdentityReference.Value;
Console.WriteLine("-> UpdateAccountRightrs() Account: " + accountName);
Console.WriteLine("-> UpdateAccountRightrs() Rights: " + ace.FileSystemRights);
Console.WriteLine("-> UpdateAccountRightrs() Account: " + accountName);

if (ace.FileSystemRights != FileSystemRights.FullControl)
ProvideFullRights(folderPath, accountName);
}

Console.WriteLine("<- UpdateAccountRightrs()");
}




/// <summary>
/// Provide the full rights to the account
/// </summary>
/// <param name="filePath"></param>
/// <param name="accountName"></param>
private static void ProvideFullRights(string folderPath, string accountName)
{
Console.WriteLine("-> ProvideFullRights() accountName: " + accountName);

if ((folderPath.Length == 0) || (accountName.Length == 0))
return;

FileSecurity fs = File.GetAccessControl(folderPath);
fs.AddAccessRule(new FileSystemAccessRule(accountName,
FileSystemRights.FullControl, AccessControlType.Allow));
File.SetAccessControl(folderPath, fs);

Console.WriteLine("<- ProvideFullRights()");
}

Have you tried the Visual Studio group in case someone has already
figured this out? You could post the same question again to both groups
(thus seeing all answers in both places) or if you post separately you
might let the folks in both groups know if you got an answer.

I can't help personally but have a feeling that the system is designed
to not allow you to do what you wish to do.

You need to set the ACLs during the install. The install needs to run with
Administrator privileges. Don't give Users Full Control. Figure out exactly
what is needed and give them the needed permissions. At most they need
Modify. This is the way secure OS' are supposed to work. Users can change
user settings. Administrators can change system settings.

use the ATL security classes as they seem to provide the easiet interface to
use for C++ programmers to adjust ACLs.

You may wish to take a step back though and examine whether you application
truly needs to set ACLs. If the data is user-based rather than program-wide
data that should be shared by all users, you will need to rethink your
strategy and start storing data in the recommended locations.
