write protection mode will not change

I use this following code to remove the write protection folder so that I can delete that. But It won't work.
File.SetAttributes(#"F:\File", FileAttributes.Normal);
File.Delete(#"F:\File");
How can I remove the write protection?
If I can remove file protection from the disk, so give some codes to do that.
Any help will be appreciated
Thanks in advance

There is a difference between Folder and File. With this you will remove the readonly atribute and delete the folder.
var di = new DirectoryInfo(#"F:\File");
di.Attributes &= ~FileAttributes.ReadOnly;
di.Delete(true);
EDIT:
Formating USB drive. You can read the article.
public static bool FormatDrive(string driveLetter,
string fileSystem = "NTFS", bool quickFormat=true,
int clusterSize = 8192, string label = "", bool enableCompression = false )
{
if (driveLetter.Length != 2 || driveLetter[1] != ':'|| !char.IsLetter(driveLetter[0]))
return false;
//query and format given drive
ManagementObjectSearcher searcher = new ManagementObjectSearcher
(#"select * from Win32_Volume WHERE DriveLetter = '" + driveLetter + "'");
foreach (ManagementObject vi in searcher.Get())
{
vi.InvokeMethod("Format", new object[]
{ fileSystem, quickFormat,clusterSize, label, enableCompression });
}
return true;
}
You should put the driveLetter like this: "F:"

Lenovo BIOS WMI - InvalidQuery

I'm about to create a tool which gets some system information.
Only the Lenovo BIOS (WakeOnLAN) request isn't doing what I want.
The debugger always stops with a "invalid request" error message.
I tried the following...
ManagementObjectSearcher searcher = new ManagementObjectSearcher("\\\\" + textBox1.Text + "\\root\\wmi", "SELECT * FROM Lenovo_BiosSetting WHERE InstanceName='ACPI\\PNP0C14\\1_0'");
ManagementObjectSearcher searcher = new ManagementObjectSearcher("\\\\" + textBox1.Text + "\\root\\wmi:Lenovo_BiosSetting.InstanceName='ACPI\\PNP0C14\\1_0'");
Code:
//LenovoWOL
public string GetLenovoWOL()
{
ManagementObjectSearcher searcher = new ManagementObjectSearcher("\\\\" + textBox1.Text + "\\root\\wmi:Lenovo_BiosSetting", "SELECT * FROM ACPI\\PNP0C14\\1_0");
foreach (ManagementObject wmi in searcher.Get())
{
try
{
return Environment.NewLine + wmi.GetPropertyValue("CurrentSetting").ToString();
}
catch { }
}
return "Unknown";
}
Only if I remove the InstanceName part, the code works.
Could someone if you tell me, what I'm doing wrong.
Thanks for your help

I found a solution.
Here my code. It's not pretty but it works.
ManagementPath path = new ManagementPath()
{
NamespacePath = #"root\wmi",
Server = textBox1.Text
};
ManagementScope scope = new ManagementScope(path);
SelectQuery Sq = new SelectQuery("Lenovo_BiosSetting");
ManagementObjectSearcher objOSDetails = new ManagementObjectSearcher(scope, Sq);
ManagementObjectCollection osDetailsCollection = objOSDetails.Get();
foreach (ManagementObject MO in osDetailsCollection)
{
if (MO["CurrentSetting"].ToString().Contains("WakeOnLAN"))
{
string[] arr = new string[3];
ListViewItem itm;
//add items to ListView
arr[0] = "";
arr[1] = "WakeOnLAN";
arr[2] = MO["CurrentSetting"].ToString();
itm = new ListViewItem(arr);
listView200.Items.Add(itm);
}
}

Document printed or not in C#

I used following code to print a pdf :
var fileName = filepath;
ProcessStartInfo psInfo = new ProcessStartInfo();
psInfo.Arguments = ConfigurationManager.AppSettings["printer_name"];
psInfo.FileName = fileName;
psInfo.WindowStyle = ProcessWindowStyle.Hidden;
psInfo.Verb = "print";
psInfo.CreateNoWindow = false;
psInfo.UseShellExecute = true;
process = Process.Start(psInfo);
following to get status of printer :
string query = string.Format("SELECT * from Win32_Printer "+ "WHERE Name LIKE '% {0}'",printerName);
ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);
ManagementObjectCollection coll = searcher.Get();
foreach (ManagementObject printer in coll)
{
foreach (PropertyData property in printer.Properties)
{
Logger.LogInfo(""+property.Name, "" +property.Value);
}
}
and also tried following to monitor Print queue :
LocalPrintServer server = new LocalPrintServer();
PrintQueueCollection queueCollection = server.GetPrintQueues();
PrintQueue printQueue = null;
foreach (PrintQueue pq in queueCollection)
{
if (pq.FullName == "HP LaserJet P1505n")
printQueue = pq;
}
int numberOfJobs = 0;
if (printQueue != null)
numberOfJobs = printQueue.NumberOfJobs;
All i want to do is to know is wether the document i did print using (1) is printed succesfully or not!! (2)nd code Snippet just shows same property anme and values always.So cannot notify print status.(3)rd code Snippet always monitors queue once and says '0' numberofjobs.
So what is the actual way to getback the print status?

To Know about print job status..! Try this,
SelectQuery qry = new SelectQuery("PrintJob");
using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(qry))
using (ManagementObjectCollection printJobs = searcher.Get())
foreach (ManagementObject printJob in printJobs)
{
string name = (string) product["Name"];
string[] nameParts = name.Split(',');
string printerName = nameParts[0];
string jobNumber = nameParts[1];
string document = (string) product["Document"];
string jobStatus = (string) product["JobStatus"];
}
I hope this helps.

I'm using WMI in C# to get all the installed softwares but it doesn't show all the softwares only Microsoft ones

public ManagementScope GetScope()
{
try
{
//string classScope="winmgmts:" + "{impersonationLevel=impersonate}!\\" + strComputer + "\\root\\cimv2";
string serverString = #"root\cimv2";
ManagementScope scope = new ManagementScope(serverString);
ConnectionOptions options = new ConnectionOptions
{
Impersonation = ImpersonationLevel.Impersonate,
Authentication = AuthenticationLevel.Connect,
EnablePrivileges = true
};
scope.Options = options;
return scope;
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
throw;
}
}
public void InvokeMethodsFunctions1()
{
ManagementScope mScope = GetScope();
mScope.Connect();
if (mScope.IsConnected)
{
ManagementClass processClass =
new ManagementClass(mScope.Path);
ManagementObjectSearcher mos = new ManagementObjectSearcher(mScope, new ObjectQuery("SELECT * FROM Win32_Product"));
//get collection of WMI objects
ManagementObjectCollection queryCollection = mos.Get();
using (System.IO.StreamWriter file = new System.IO.StreamWriter(#"Result.txt"))
{
textBox1.Text = "";
//enumerate the collection.
foreach (ManagementObject m in queryCollection)
{
// access properties of the WMI object
string line = " " + m["Name"] + " , InstallDate : " + m["InstallDate"] + " LocalPackage : " + m["LocalPackage"];
Console.WriteLine(line);
file.WriteLine(line);
textBox1.Text += line + "\n";
}
}
}
}
So whats wrong in my Code ?

There is nothing wrong , the Win32_Product WMI class only list the products installed by the Windows Installer (MSI).

I just tested the following, simplified version of your code and I see everything installed on my pc, even services I wrote and installed myself:
var products = new ManagementObjectSearcher(new ObjectQuery("SELECT * FROM Win32_Product"));
var result = products.Get();
foreach (var product in result)
{
Console.WriteLine(product.GetPropertyValue("Name").ToString());
}
Console.ReadLine();
It looks like you are narrowing your query by scope, which is possibly why you aren't seeing everything, try the above and see if you have more luck.

How to get the description of a running process on a remote machine?

I have tried two ways to accomplish this so far.
The first way, I used System.Diagnostics, but I get a NotSupportedException of "Feature is not supported for remote machines" on the MainModule.
foreach (Process runningProcess in Process.GetProcesses(server.Name))
{
Console.WriteLine(runningProcess.MainModule.FileVersionInfo.FileDescription);
}
The second way, I attempted using System.Management but it seems that the Description of the ManagementObject is the she same as the Name.
string scope = #"\\" + server.Name + #"\root\cimv2";
string query = "select * from Win32_Process";
ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);
ManagementObjectCollection collection = searcher.Get();
foreach (ManagementObject obj in collection)
{
Console.WriteLine(obj["Name"].ToString());
Console.WriteLine(obj["Description"].ToString());
}
Would anyone happen to know of a better way to go about getting the descriptions of a running process on a remote machine?

Well I think I've got a method of doing this that will work well enough for my purposes. I'm basically getting the file path off of the ManagementObject and getting the description from the actual file.
ConnectionOptions connection = new ConnectionOptions();
connection.Username = "username";
connection.Password = "password";
connection.Authority = "ntlmdomain:DOMAIN";
ManagementScope scope = new ManagementScope(#"\\" + serverName + #"\root\cimv2", connection);
scope.Connect();
ObjectQuery query = new ObjectQuery("select * from Win32_Process");
ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);
ManagementObjectCollection collection = searcher.Get();
foreach (ManagementObject obj in collection)
{
if (obj["ExecutablePath"] != null)
{
string processPath = obj["ExecutablePath"].ToString().Replace(":", "$");
processPath = #"\\" + serverName + #"\" + processPath;
FileVersionInfo info = FileVersionInfo.GetVersionInfo(processPath);
string processDesc = info.FileDescription;
}
}
