Problem with ManagementObject..

G

Guest

hi,
I am trying following code.

string fileObject = @"C:\Documents and Settings\myfolder\Temp.txt";
ManagementBaseObject ret = null;
ManagementPath path = new ManagementPath( );
path.Server = @"ServerName"; // Assuming that server name is server i am
trying to connect to

path.NamespacePath = @"root\cimv2";
path.RelativePath = @"Win32_LogicalFileSecuritySetting.Path=" + "'" +
fileObject + "'";
ManagementObject lfs = new ManagementObject(path);

// Get the security descriptor for this object
bool EnablePrivileges = lfs.Scope.Options.EnablePrivileges;
lfs.Scope.Options.EnablePrivileges = true;
// Dump all trustees (this includes owner)
string accountName, SID;
foreach (ManagementBaseObject b in lfs.GetRelated())
{
accountName= (string)b["AccountName"]; --I am getting error on
this line
SID = (string)b["SID"];
Console.WriteLine("Trustees {0} is {1}", b["AccountName"],
b["SID"]);
}

I am getting error on the line marked(--I am getting error on this line) in
above code. When i tried above code for local machine everything is working
fine.
Thanks in advance for help.

Error message simply says "Not Found"

This works for me (on XP and higher),

using System;
using System.Management;
using System.Collections;

class Tester {
public static void Main()
{
// Create FileObjectSecurity passing the file object (filepath) to the
ctor.
// Watch the double backslashes !!!!
string FileSystemObject = @"c:\\rssfeed.xml";

ManagementPath path = new ManagementPath( );

path.RelativePath = @"Win32_LogicalFileSecuritySetting.Path=" + "'" +
FileSystemObject + "'";
ManagementObject lfs = new ManagementObject(path);
foreach (ManagementBaseObject b in lfs.GetRelated())
{
string domainName= b["ReferencedDomainName"].ToString();
string accountName= b["AccountName"].ToString();
string SID = b["SID"].ToString();
Console.WriteLine("Trustees {0}\\{1} is {2}",
b["ReferencedDomainName"], b["AccountName"], b["SID"]);
}
}
}

if it doesn't work for you, I would suggest you try wbemtest.exe and issue
the same query and check the Win32_LogicalFileSecuritySetting object
associators to see what is returned.

Looks like you are using it for local machine only. I would like to use this
for remote machine.

No matter, your problem is not related to local or remote machines, your
fileobject path is wrong, Didn't you notice ....

// Watch the double backslashes !!!!

in my sample.

Hi.

IMO, this has to work with double back slash. Will you try the sxample that
Willy has provided to see if it works on you machine?

HI Kevin,
Thanks for replying back. I used the sample code and it works like champ as
long as i use it for local machine only. First of all how do i query remote
machine for information. I guess i have to use Path.Server property. Correct?
The moment i use that i get the error mentioned in my post.
I am using actual server name(and not the IPAddress). My managementpath
declaration looks like:

string fileObject = @"C:\Documents and Settings\myfolder\Temp.txt";
ManagementBaseObject ret = null;
ManagementPath path = new ManagementPath( );
path.Server = @"ServerName"; // Assuming that server name is server i am
trying to connect to

path.NamespacePath = @"root\cimv2";
path.RelativePath = @"Win32_LogicalFileSecuritySetting.Path=" + "'" +
fileObject + "'";
ManagementObject lfs = new ManagementObject(path);
Please let me know what i am doing wrong.

Like Kevin and I said before, you need the double back slashes in your
filepath!

string fileObject = @"C:\Documents and Settings\myfolder\Temp.txt";

should be...

string fileObject = @"C:\\Documents and Settings\\myfolder\\Temp.txt";

Willy.
