i have a short script that i need to convert and it is proving pretty tricky!
Many Thanks,

Hi,
Maybe seeing the original Powershell script could help

Surround your code with <pre></pre> tags so it is readable.
I must get a clever new signature for 2011.

ok, i have done this now.

Read a line of the script, and translate/convert it to C#. It's a manual proces where you interpret what the script should do, and write some code that does the same.

Can you point out where you're stuck with translating?

the big problem is witht he casting. in PS it automatically decides what object type it needs to be but in C# it need to be specified. the code below compiles but line 11 errors saying - "Invalid parameter"
any help would be great thanks.
here is what i have so far:
InvokeMethodOptions imo = new InvokeMethodOptions();
imo.Timeout = new TimeSpan(0, 0, 0, 5);
NTAccount ID = new NTAccount(uName);
string SID = ID.Translate(typeof(SecurityIdentifier)).ToString();
string WMISDDL = "A;CI;CCWP;;;" + SID;
string WMISDDLPartialMatch = "A;\\w*;\\w+;;;" + SID;
ManagementClass security = new ManagementClass(new ManagementPath("\\\\" + server + "\\root\\Security:__SystemSecurity"));
object BinarySD = null;
ManagementBaseObject result = (ManagementBaseObject)security.InvokeMethod("GetSD", (ManagementBaseObject)BinarySD, imo);
ManagementClass converter = new ManagementClass("\\\\" + server + "\\root\\CIMV2:Win32_SecurityDescriptorHelper");
ManagementBaseObject CurrentWMISDDL = (ManagementBaseObject)converter.InvokeMethod("BinarySDToSDDL", (ManagementBaseObject) BinarySD, imo);
string NewWMISDDL;
if (CurrentWMISDDL.Properties["SDDL"].ToString() == WMISDDLPartialMatch && CurrentWMISDDL.Properties["SDDL"].ToString() != WMISDDL)
{
NewWMISDDL = CurrentWMISDDL.Properties["SDDL"].ToString().Replace(WMISDDLPartialMatch, WMISDDL);
}
else
{
NewWMISDDL = CurrentWMISDDL.Properties["SDDL"].ToString() + "(" + WMISDDL +")";
}
ManagementObject WMIBinarySD = (ManagementObject)converter.InvokeMethod("SDDLToBinarySD", new object[] { NewWMISDDL });
ManagementBaseObject WMIConvertedPerms = (ManagementBaseObject)WMIBinarySD.Properties["BinarySD"].Value;
if (CurrentWMISDDL.Properties["SDDL"].ToString().Contains(WMISDDL.ToString()))
{
Console.WriteLine("Current WMI permissions already match desired value.");
}
else
{
result = (ManagementObject)security.InvokeMethod("SetSD", new object[] { WMIConvertedPerms });
if ((Int32)result.GetPropertyValue("ReturnValue") == 0)
{
Console.WriteLine("Applied WMI security permissions.");
}
else
{
Console.WriteLine("Error applying permissions!");
}
}
}
catch (Exception exp)
{
Console.ForegroundColor = ConsoleColor.Red;
Console.WriteLine("Error: " + exp.Message.ToString());
Console.ResetColor();
}
Many Thanks,
Phil

That'd be this line;
ManagementBaseObject CurrentWMISDDL = (ManagementBaseObject)converter.InvokeMethod("BinarySDToSDDL", (ManagementBaseObject) BinarySD, imo);
Would that be the invocation of this[^] method? Seems to return an uint32 according to the documentation, taking two parameters.
Take care that you copy the correct version of all the references that the script is using.

tried that.. didn't work!
says it cant convert it, and other parts of the programme fail!

Compile-time or run-time?
Break up the statement into smaller pieces, so that you can check the assignment, the cast and the invoking of the function separately.

run-time.
i have tried what you suggested and it all looks fine!

If you look above the text box when you enter a reply, there are two "link" widgets.
If you highlight your link, and press one of the widgets, it converts the link to a clickable link: easier for people to use, and looks better!
Your original:

First "link"
An extensible math expression parser with plug-ins
Second "link[^]" (It gives a "new window/tab" option to the link)
An extensible math expression parser with plug-ins[^]
Much prettier!

Hi,
I am trying to delete some nodes from an xml document. I am using LINQ to xml and want to stick to this approach. Here is my XML document:
<?xml version="1.0" encoding="utf-8"?>
<Project>
<Clips>
<Clip ID="1" Sequence="1">
<Name></Name>
<Description></Description>
<Location></Location>
<Duration></Duration>
<Images>
<Image ID="1">
<Name></Name>
<Description></Description>
<Location></Location>
<StartTime></StartTime>
<EndTime></EndTime>
</Image>
</Images>
</Clip>
<Clip ID="2" Sequence="1">
<Name>Bazingaaa</Name>
<Description>Masdljaslda</Description>
<Location>C:\Videos</Location>
<Duration>00:00:30</Duration>
<Images>
<Image ID="1">
<Name>Faheem</Name>
<Description>MyImage</Description>
<Location>C:\Images</Location>
<StartTime>00:00:00</StartTime>
<EndTime>00:00:10</EndTime>
</Image>
<Image ID="2">
<Name>Fawaz</Name>
<Description>MyImage</Description>
<Location>C:\Images</Location>
<StartTime>00:00:00</StartTime>
<EndTime>00:00:10</EndTime>
</Image>
</Images>
</Clip>
</Clips>
</Project>
I have to perform two cases. 1. Delete clip node based on ID. 2. Clear whole project root tag.
I am using the following code to delete nodes.
IEnumerable<XElement> clip = (from c in this.oProjectDoc.Element("Project").Element("Clips").Elements("Clip")
where c.Attribute("ID").Value.Equals(ID)
select c);
foreach (XElement xe in clip)
xe.Remove();
this.oProjectDoc.Save(this.oProjectPath.FullName);
Have tried this as well.
var q = from node in oProjectDoc.Root.DescendantsAndSelf("Clips")
let attr = node.Attribute("ID")
where attr != null && attr.Value == clipId
select node;
q.ToList().ForEach(x => x.Remove());
oProjectDoc.Save(this.oProjectPath.FullName);
Problem happens when i try to delete the last clip node or the clear the whole root "Project" tag. I get a lingering end node tag. Like:
</Clip>
Any solutions to that. Kindly please also tell me how can clear all my nodes from xml document. i.e. totally empty my xml document and start afresh without deleting the xml file.
Thanks in advance
Regards...

Instead of this:
var q = from node in oProjectDoc.Root.DescendantsAndSelf("Clips")
let attr = node.Attribute("ID")
where attr != null && attr.Value == clipId
select node;
q.ToList().ForEach(x => x.Remove());
Why can't you do this:
var q = (from node in oProjectDoc.Root.DescendantsAndSelf("Clips")
let attr = node.Attribute("ID")
where attr != null && attr.Value != clipId
select node);
oProjectDoc.Root.RemoveAll();
foreach(XElement element in q)
{
oProjectDoc.Root.Add(element);
}

Hi,
will u tell me, how can i display an warning message to the user if the file he/she is uploading is open in his machine..
In my Application, i can upload only a file of type *.txt or *.csv,
so could u tell me how can i display a message to the user, when he is uploading a file of (.txt or .csv)type only when that particular file is open in his machine..
As of now in my application, it makes the application crash if that uploading file is open in user machine..
please check my code here..
private void BtnBrowseClick(object sender, RoutedEventArgs e)
{
OpenFileDialog file1 = new OpenFileDialog { Multiselect = false, Filter = "All Supported Files |*.txt;*.csv|Text|*.txt|CSV |*.csv"};
if (file1.ShowDialog() == true)
{
new FileInfo(file1.FileName);
try
{
using (Stream str = file1.OpenFile())
{
TextReader reader = new StreamReader(str);
reader.ReadToEnd();
txtFileName.Text = file1.FileName;
txtFileName.IsEnabled = false;
}
}
catch
{
txtFileName.Text = file1.FileName;
txtFileName.IsEnabled = false;
MessageBox.Show("Please check the file has been Closed before you upload", "Manual File Upload");
}
}
}
It is showing warning message if i change the permission of that file(.txt or .csv) or if i dint changed the permission, it is not showing any warning message, could u tell me how can i do it in a right way..
If possible tell me with a sample code, so i change my code or alter it...
Thanks

There is a hack using a Try Catch Block and catching an IOException . In your case you could do something like this,
private void BtnBrowse_Click(object sender, RoutedEventArgs e)
{
OpenFileDialog file1 = new OpenFileDialog { Multiselect = false, Filter = "All Supported Files |*.txt;*.csv|Text|*.txt|CSV |*.csv" };
if (file1.ShowDialog() == true)
{
new FileInfo(file1.FileName);
using (Stream str = file1.OpenFile())
{
try
{
System.IO.FileStream fs = System.IO.File.OpenWrite(file1.FileName);
fs.Close();
}
catch (IOException)
{
MessageBox.Show("Please check the file has been Closed before you upload", "Manual File Upload");
return;
}
TextReader reader = new StreamReader(str);
reader.ReadToEnd();
textBox1.Text = file1.FileName;
textBox1.IsEnabled = false;
}
}
}
This solution is not very elegant but it works  .The only other way I know would be to use the proper Win32 API's, which is tiresome.
Happy Coding

I used the above code in my application,
In both the condition like if the uploading file is open and close it is executing the catch statement,
try block is not executing if the uploading file is closed in user machine...
and also the code below the catch block is not executing...
only catch block is executing in this case,
So can u tell me how can i alter it to make it run successfully...

Sorry for that, but in your case this won't work as the OpenFileDialog Locks the file itself, so the IOException will always be caught. I created a function like this
private bool FileInUse(string fileName)
{
try
{
System.IO.FileStream fs = System.IO.File.OpenWrite(fileName);
fs.Close();
return true;
}
catch (IOException ex)
{
return false;
}
}
and then calling it like this
OpenFileDialog file1 = new OpenFileDialog();
if (file1.ShowDialog() == true)
{
if (!FileInUse(file1.FileName))
{
MessageBox.Show("Already Open");
}
else
{
using (Stream str = file1.OpenFile())
{
TextReader reader = new StreamReader(str);
reader.ReadToEnd();
textBox1.Text = file1.FileName;
textBox1.IsEnabled = false;
}
}
}
but this only works if the file is locked by the application that opens it (such as Word), otherwise if the file is open in an application that doesn't lock the file (such as NotePad), this always returns true.
