New Post: Task schedular OXFF Error

Niveditha — Tue, 21 May 2013 15:05:16 GMT

Hello,

I am also facing the similar situation where the scheduled task ends with 0Xff in the last result. When I run the script alone it is working fine. but I am facing issue only when I run with the task scheduler. And the script is not completing successfully. Can any one please help me on this.

sisir14, please see note on prefacing Action references on this page with 'Microsoft.Win32.TaskScheduler'

Updated Wiki: Examples

dahall — Mon, 20 May 2013 15:47:12 GMT

Below are some examples of how to use most of the functions of the library:

Connecting to a remove server
Using the editor
Simple example
Enumerate all tasks
Complex example
Task history example

On all these examples, if you get an error on ambiguous references for 'Action', please preface it with 'Microsoft.Win32.TaskScheduler.Action'.

You can also go to these pages for more sample code:

Connecting to a remote server

// Connect to the computer "REMOTE" using credentials
TaskService ts = new TaskService("\\REMOTE", "myusername", "MYDOMAIN", "mypassword");

Using the editor

// Get the service on the local machine
using (TaskService ts = new TaskService())
{
   // Create a new task
   const string taskName = "Test";
   Task t = ts.AddTask(taskName, 
      new TimeTrigger() { StartBoundary = DateTime.Now + TimeSpan.FromHours(1), Enabled = false },
      new ExecAction("notepad.exe", "c:\\test.log", "C:\\"));

   // Edit task and re-register if user clicks Ok
   TaskEditDialog editorForm = new TaskEditDialog();
   editorForm.Editable = true;
   editorForm.RegisterTaskOnAccept = true;
   editorForm.Initialize(t);
   // ** The four lines above can be replaced by using the full constructor -- TaskEditDialog(t, true, true)
   editorForm.ShowDialog();

   // Remove the task we just created
   ts.RootFolder.DeleteTask(taskName);
}

Simple example

// Get the service on the local machine
using (TaskService ts = new TaskService())
{
   // Create a new task definition and assign properties
   TaskDefinition td = ts.NewTask();
   td.RegistrationInfo.Description = "Does something";
   td.Principal.LogonType = TaskLogonType.InteractiveToken;

   // Add a trigger that will fire the task at this time every other day
   DailyTrigger dt = (DailyTrigger)td.Triggers.Add(new DailyTrigger { DaysInterval = 2 });
   dt.Repetition.Duration = TimeSpan.FromHours(4);
   dt.Repetition.Interval = TimeSpan.FromHours(1);

   // Add a trigger that will fire every week on Friday
   td.Triggers.Add(new WeeklyTrigger { StartBoundary = DateTime.Today + TimeSpan.FromHours(2), DaysOfWeek = DaysOfTheWeek.Friday });

   // Add an action that will launch Notepad whenever the trigger fires
   td.Actions.Add(new ExecAction("notepad.exe", "c:\\test.log", null));

   // Register the task in the root folder
   const string taskName = "Test";
   ts.RootFolder.RegisterTaskDefinition(taskName, td);

   // Retrieve the task, change the trigger and re-register it
   Task t = ts.GetTask(taskName);
   td = t.Definition;
   td.Triggers[0].StartBoundary = DateTime.Today + TimeSpan.FromDays(7);
   ts.RootFolder.RegisterTaskDefinition(taskName, td);

   // Remove the task we just created
   ts.RootFolder.DeleteTask(taskName);
}

Enumerate all tasks

void EnumAllTasks()
{
   using (TaskService ts = new TaskService())
      EnumFolderTasks(ts.RootFolder);
}

void EnumFolderTasks(TaskFolder fld)
{
   foreach (Task task in fld.Tasks)
      ActOnTask(task);
   foreach (TaskFolder sfld in fld.SubFolders)
      EnumFolderTasks(sfld);
}

void ActOnTask(Task t)
{
   // Do something interesting here
}

Complex example

string user = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
bool preWin7 = true;

// Get the service on the local machine
using (TaskService ts = new TaskService())
{
   // Display version and server state
   Version ver = ts.HighestSupportedVersion;
   bool newVer = (ver >= new Version(1, 2));
   Console.WriteLine("Highest version: " + ver);
   Console.WriteLine("Server: {0} ({1})", ts.TargetServer, ts.Connected ? "Connected" : "Disconnected");

   // Output all of the running tasks
   Console.WriteLine("Running tasks:");
   foreach (RunningTask rt in ts.GetRunningTasks(true))
   {
      if (rt != null)
      {
         Console.WriteLine("+ {0}, {1} ({2})", rt.Name, rt.Path, rt.State);
         if (ver.Minor > 0)
            Console.WriteLine("  Current Action: " + rt.CurrentAction);
      }
   }

   // Output all the tasks in the root folder with their triggers and actions
   TaskFolder tf = ts.RootFolder;
   Console.WriteLine("\nRoot folder tasks ({0}):", tf.Tasks.Count);
   foreach (Task t in tf.Tasks)
   {
      try
      {
         Console.WriteLine("+ {0}, {1} ({2})", t.Name, t.Definition.RegistrationInfo.Author, t.State);
         foreach (Trigger trg in t.Definition.Triggers)
            Console.WriteLine(" + {0}", trg);
         foreach (Action act in t.Definition.Actions)
            Console.WriteLine(" = {0}", act);
      }
      catch { }
   }

Task history example
Only works with release 1.6.2 or source code drop 66948 and later and requires the inclusion of the TaskSchedulerEditor assembly.

TaskEventLog log = new TaskEventLog(task.Path);
List<ListViewItem> c = new List<ListViewItem>(100);
foreach (TaskEvent item in log)
   c.Add(new ListViewItem(new string[] { item.Level, item.TimeCreated.ToString(), item.EventId.ToString(),
      item.TaskCategory, item.OpCode, item.ActivityId.ToString() }));

When i did tried to run the code getting error: Error 3 'Action' is an ambiguous reference between 'System.Action' and 'Microsoft.Win32.TaskScheduler.Action' Believe some reference is missing.Could you please let me know how to add that reference as i am not getting it neither .NET or in COM list. Thanks, Sisir

Hi Folks,

I do have a requirement:

1.Need to get the status of all scheduled tasks schduled in a remote machine
2.Based on status need to send an alert email

This is my sample code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Win32.TaskScheduler;
using System.Threading;

{
using (TaskService task = new TaskService())
{
TaskDefinition td = task.NewTask();
td.RegistrationInfo.Description = "RF Report";
td.Actions.Add(new ExecAction("notepad.exe", "c:\test.log", null));
while (true)
{
Task taskdDef = task.FindTask("RF Report");
//string registeredTask;
//string[] taskCollection = { "", "", "" };
//foreach (string str in taskCollection)
//{

//For Each registeredTask In taskCollection

switch (taskdDef.State)
{
case TaskState.Queued:
Console.WriteLine("Queued");
break;
case TaskState.Ready:
Console.WriteLine("Ready");
break;
case TaskState.Unknown:
Console.WriteLine("Unknown");
break;

// Console.WriteLine("Mail was sent successfully!");
//}
//catch (Exception ep)

// Console.WriteLine(ep.Message);
//}

//}
}

string sSource = "MyCustom Group";
string sLog = "Application";
string sEvent = "";

if (!EventLog.SourceExists(sSource))
EventLog.CreateEventSource(sSource, sLog);

EventLog.WriteEntry(sSource, sEvent, EventLogEntryType.Error, 234);

}
}
}
}

Not sure how to connect to the remote server/machine and read and get the task status details and also need to amend that status details in email.

Could anyone please look into my code and suggest.

Many Thanks,
Sisir

I'm not clear what you are trying to accomplish. However, you can find examples of how to connect to a remote server and how to retrieve information about tasks in the Documentation on the [Examples page](https://taskscheduler.codeplex.com/wikipage?title=Examples). I don't believe this is an issue with the library so I will be closing this issue.

New Post: Hung Scheduled Task Won't Stop

mattbbpl — Thu, 16 May 2013 15:29:50 GMT

Hello,

We've been using this API to manage scheduled tasks (mostly by enabling them and disabling them) on a number of remote servers during software deployments, and it works quite well the majority of the time.

Occasionally, however, we run into a situation where a scheduled task gets "hung" (remains in a "Running" state perpetually, even though it's not actually doing any work). This happens most often on servers with slower connections, although it happens on faster servers as well with a decreased regularity.

I've been able to recreate the situation relatively easily by creating the conditions outlined here:
http://blogs.technet.com/b/rspitz/archive/2010/11/07/scheduled-tasks-appear-hung-in-the-running-state-on-windows-server-2003-based-systems.aspx

While in this state, we can't stop the task (either through the Task.Stop() API call or through the Windows Scheduled Task interface) and are forced to restart the Task Scheduler service to free it up.

Since the Windows interface doesn't seem to allow us to stop tasks in this condition I don't have much hope for the API, but I have to ask: Has anyone here encountered this before and found a way to deal with it and/or avoid it when using this API?

I was using the GetTasks method.
Thanks, don't know why I missed that :) I have now all tasks and I can toggle if I wanna see the ones that are hidden.

I now will try to see if I can search for a task by name and list that.

You must be trying to use the GetTasks method. There is an easier way. Please see the "Enumerate all tasks" sample code on the Examples page.

Hi,

This is very cool. I am trying to setup an example console app that will list all tasks from root and subfolders. I have come so far that is has displayed the first tasks, but I can see it excludes the hidden. It requires regex it said. ? can some please help me in getting all tasks also the hidden and maybe how to retrive all tasks beneth layers of subfolders recursively.

Thanks in advance.

New Post: Cannot have windows with handles (eg NativeWindow) when running at boot in system account???

I don't know if this will work, but I would try registering the task using the System or Local Service account and then assigning the EventTrigger or SessionStateChangeTrigger to call whatever action you need to take place. Make sure your action does not require access to resources (networking, files, etc.) that may not be available to the account under which you registered the task.

New Post: COMException connecting to Windows 2012 Task Scheduler remotely

As I mentioned, I don't have a system to test this on, but I have an idea for someone to try. Instead of trying to get the Definition, will someone try getting the Xml and see if an exception is ever thrown? For example,

var ts = new TaskService(IP address, userId, domain, password);
foreach (Task task in ts.RootFolder.Tasks)
{
  Console.Writeline(task.Xml);
}

My theory is that the 1.3 library chokes on parsing the 1.4 XML. While Microsoft may not chose to fix this, I may be able to work around it in my code. I'm also curious if there are XML results that have the 1.3 version (or earlier) as then the library could just exclude those it can't understand and work with those it can.
