I want to use c# and WMI to start a process remotely in another computer. I've made some initial research and found out that i ultimately have to use a processclass. The "Win32_Process" was the first thing that seemed obvious to be used, however, it seems it is limited to represent only local processes. What other Windows process classes can I use?
Here is what the code when using Win32_ScheduledJob class:
static public String RemoteConnect()
{
try
{
ConnectionOptions conn = new ConnectionOptions();
conn.Username = @"JV";
conn.Password = @"Nazpal6180";
conn.EnablePrivileges = true;
conn.Impersonation = System.Management.ImpersonationLevel.Impersonate;
ManagementScope scope = new ManagementScope("\\\\phsd194-JV\\root\\cimv2", conn);
//scope.Options.Impersonation = System.Management.ImpersonationLevel.Impersonate;
//scope.Options.EnablePrivileges = true;
scope.Connect();
ManagementPath managementPath = new ManagementPath("Win32_ScheduledJob");
ObjectGetOptions objectGetOptions = new ObjectGetOptions();
ManagementClass classInstance = new ManagementClass(scope, managementPath, objectGetOptions);
object[] objectsIn = new object[7];
objectsIn[0] = "calc.exe";
objectsIn[1] = "********140000.000000+480";
objectsIn[5] = true;
object outParams = classInstance.InvokeMethod("Create", objectsIn);
String response = "Creation of the process returned: " + outParams;
return response;
}
catch (ManagementException err)
{
String response = "An error occurred while trying to execute the WMI method: " + err.Message;
//Console.WriteLine("An error occurred while trying to execute the WMI method: " + err.Message);
return response;
}
}
As you point in your comments, the Win32_Process.Create
method cannot be used to start an interactive process remotely, so as workaround you can use the Win32_ScheduledJob
class with the Create method
.
Check this sample app, which start the notepad in a remote machine in one minute , (Assuming which the time of the remote machine is the same of the local machine, if not you can get the local time using Win32_LocalTime
or Win32_UtcTime
from the remote machine and then convert to UTC).
using System;
using System.Collections.Generic;
using System.Text;
using System.Management;
namespace ConsoleApplication11
{
class Program
{
private static string DateTimetoUTC(DateTime dateParam)
{
string buffer = dateParam.ToString("********HHmmss.ffffff");
TimeSpan tickOffset = TimeZone.CurrentTimeZone.GetUtcOffset(dateParam);
buffer += (tickOffset.Ticks >= 0) ? '+' : '-';
buffer += (Math.Abs(tickOffset.Ticks) / System.TimeSpan.TicksPerMinute).ToString("d3");
return buffer;
}
static void Main(string[] args)
{
try
{
ConnectionOptions conn = new ConnectionOptions();
conn.Username = "theusername";
conn.Password = "password";
//connectoptions.Authority = "ntlmdomain:";
conn.EnablePrivileges = true;
ManagementScope scope = new ManagementScope(@"\\192.168.52.128\root\cimv2", conn);
scope.Connect();
Console.WriteLine("Connected");
ObjectGetOptions objectGetOptions = new ObjectGetOptions();
ManagementPath managementPath = new ManagementPath("Win32_ScheduledJob");
ManagementClass classInstance = new ManagementClass(scope, managementPath, objectGetOptions);
ManagementBaseObject inParams = classInstance.GetMethodParameters("Create");
inParams["Command"] = @"notepad.exe";
//the itme must be in UTC format
string StartTime = DateTimetoUTC(DateTime.Now.AddMinutes(1));
Console.WriteLine(StartTime);
inParams["StartTime"] = StartTime;
ManagementBaseObject outParams = classInstance.InvokeMethod("Create", inParams, null);
Console.WriteLine("JobId: " + outParams["JobId"]);
Console.ReadKey();
}
catch(ManagementException err)
{
Console.WriteLine("An error occurred while trying to execute the WMI method: " + err.Message);
Console.ReadKey();
}
}
}
}
I believe C# has just a Process
class. I've used it for starting remote processes before.
I'd go for a server/client architecture where the server can start processes based on some kind of network call.
