Is a process running on a remote machine?

Question

I have three remote PC's to which I remotely connect. I am trying to write a simple Windows application that would display in a single window whether a particular process is running on either of the machines, e.g.

Server1: Chrome not running

Server2: Chrome IS running

Server3: Chrome IS running

I used WMI and C#. So far I've got this much:

            ConnectionOptions connectoptions = new ConnectionOptions();

            connectoptions.Username = @"domain\username";
            connectoptions.Password = "password";

            //IP Address of the remote machine
            string ipAddress = "192.168.0.217";
            ManagementScope scope = new ManagementScope(@"\\" + ipAddress + @"\root\cimv2");
            scope.Options = connectoptions;
            //Define the WMI query to be executed on the remote machine
            SelectQuery query = new SelectQuery("select * from Win32_Process");

            using (ManagementObjectSearcher searcher = new
                        ManagementObjectSearcher(scope, query))
            {

                ManagementObjectCollection collection = searcher.Get();
                foreach (ManagementObject process in collection)
                {
                    // dwarfs stole the code!! :'(                        
                }
            }

I think it is all set up correctly, but if I MessageBox.Show(process.ToString()) inside the foreach loop, I get a whole bunch of message boxes with the following text:

\\username\root\cimv2:W32_Process.Handle="XXX"

I am kind of stuck. Is there any way I can "translate" that XXX to a process name? Or else, how can actually get the names of the processes so I can use an if statement to check whether it is a "chrome" process?

Or...is my implementation an overkill? Is there an easier way to accomplish this?

Thanks a lot!

Answer 1

In your foreach, try this:

Console.WriteLine(process["Name"]);

Answer 2

You can filter the name of the process to watch in the WQL sentence, so you can write something like this

 SelectQuery query = new SelectQuery("select * from Win32_Process Where Name='Chrome.exe'");

Try this sample app

using System;
using System.Collections.Generic;
using System.Management;
using System.Text;

namespace GetWMI_Info
{
    class Program
    {

        static void Main(string[] args)
        {
            try
            {
                string ComputerName = "localhost";
                ManagementScope Scope;                

                if (!ComputerName.Equals("localhost", StringComparison.OrdinalIgnoreCase)) 
                {
                    ConnectionOptions Conn = new ConnectionOptions();
                    Conn.Username  = "";
                    Conn.Password  = "";
                    Conn.Authority = "ntlmdomain:DOMAIN";
                    Scope = new ManagementScope(String.Format("\\\\{0}\\root\\CIMV2", ComputerName), Conn);
                }
                else
                    Scope = new ManagementScope(String.Format("\\\\{0}\\root\\CIMV2", ComputerName), null);

                Scope.Connect();
                ObjectQuery Query = new ObjectQuery("SELECT * FROM Win32_Process Where Name='Chrome.exe'");
                ManagementObjectSearcher Searcher = new ManagementObjectSearcher(Scope, Query);


                foreach (ManagementObject WmiObject in Searcher.Get())
                {
                  //for each instance found, do something  
                  Console.WriteLine("{0,-35} {1,-40}","Name",WmiObject["Name"]);

                }
            }
            catch (Exception e)
            {
                Console.WriteLine(String.Format("Exception {0} Trace {1}",e.Message,e.StackTrace));
            }
            Console.WriteLine("Press Enter to exit");
            Console.Read();
        }
    }
}
