Actually, the library's documentation says, "A TimeSpan value of 1 second indicates the task is set to delete when done. A value of TimeSpan.Zero indicates that the task should not be deleted."

New Post: Delete IT After- Settings Tab - Immediately
Thanks for the reply. I tried giving TimeSpan value of 1 second but the Task Created in system's task scheduler shows '1 second' instead of 'Immediately' .

New Post: About the TriggerString
I read the source code and found that is a API: GetTriggerString for V1, but not V2.
So Task Scheduler Managed Wrapper implement it.
But I found the output string of V2 is same with the windows "task scheduler".
So it is possible that is some API of V2 to getTriggerString, no need to implement it.

New Post: About the TriggerString
The native V2 library does not include the trigger string output. It is implemented inside the "Task Scheduler" tool. I implemented it as part of the wrapper.

New Post: Delete IT After- Settings Tab - Immediately
I see the problem now. When I originally wrote the library, there were not nullable types supported in either C# or VB.NET. The native library uses strings that can have the following values:
- 'null' == 'Never delete'
- 'PT0S' (or TimeSpan.Zero) == 'Immediately'
-
'PTxx' == other times
- TimeSpan.Zero == 'Never delete'
- TimeSpan.FromSeconds(1) == 'Immediately'
-
TimeSpan (other) == other times

Updated Wiki: Home
This project provides a wrapper for the Windows Task Scheduler. It aggregates the multiple versions, provides an editor and allows for localization.
NuGet
This project's assemblies are available via NuGet.
Microsoft introduced version 2.0 (internally version 1.2) with a completely new object model with Windows Vista. The managed assembly closely resembles the new object model, but allows the 1.0 (internally version 1.1) COM objects to be manipulated. It will automatically choose the most recent version of the library found on the host system (up through 1.4). Core features include:
UI Library
There is a second library that includes localized and localizable GUI editors and a wizard for tasks which mimic the ones in Vista and later and adds optional pages for new properties. Following is the list of available UI controls:
If you are writing your own custom Task Scheduler COM Handler based on the ITaskHandler interface, there is a project template available that will stub out the majority of the work to create it in C# and a sample to show a complete one. If running your own code, this model provides much better interaction, control and memory management than running an executable.
Sample Code
There is a help file included with the download that provides an overview of the various classes. There are numerous examples under the "Documentation" tab.
You can perform a number of actions in a single line of code:
For many more options, use the library classes to build a complex task. Below is a brief example of how to use the library from C#.
For extended examples on how to the use the library, look in the source code area or look at the Examples Page. The library closely follows the Task Scheduler 2.0 Scripting classes. Microsoft has some examples on MSDN around it that may further help you understand how to use this library.

- Main Library: Task Scheduler Managed Wrapper (TaskScheduler)
- UI Library: Task Scheduler Managed Wrapper UI Library (TaskSchedulerEditor)
Microsoft introduced version 2.0 (internally version 1.2) with a completely new object model with Windows Vista. The managed assembly closely resembles the new object model, but allows the 1.0 (internally version 1.1) COM objects to be manipulated. It will automatically choose the most recent version of the library found on the host system (up through 1.4). Core features include:
- Separate, functionally identical, libraries for .NET 2.0 and 4.0.
- Unlike the base library, this wrapper helps to create and view tasks up and down stream.
- Written in C#, but works with any .NET language including scripting languages.
- Supports almost all V2 native properties, even under V1 systems.
- Maintain EmailAction and ShowMessageAction under Win8 where they have been deprecated using PowerShell
- Supports all action types (not just ExecAction) on V1 systems (XP/WS2003) and earlier (if PowerShell is installed).
- Supports multiple actions on V1 systems (XP/WS2003). Native library only supports a single action.
- Supports serialization to XML for both 1.0 and 2.0 tasks (base library only supports 2.0)
- Supports task validation for targeted version.
- Supports secure task reading and maintenance.
- Fluent methods for task creation.
- Cron syntax for trigger creation.
- Supports "custom" triggers under Win8 and later.
- Numerous work-arounds and checks to compensate for base library shortcomings.

UI Library
There is a second library that includes localized and localizable GUI editors and a wizard for tasks which mimic the ones in Vista and later and adds optional pages for new properties. Following is the list of available UI controls:
- A DropDownCheckList control that is very useful for selecting flag type enumerations.
- A FullDateTimePicker control which allows both date and time selection in a single control.
- A CredentialsDialog class for prompting for a password which wraps the Windows API.
- Simplified classes for pulling events from the system event log.
- Action editor dialog
- Trigger editor dialog
- Task editor dialog and tabbed control
- Event viewer dialog
- Task / task folder selection dialog
- Task history viewer
- Task run-times viewer
- Task creation wizard
- Task service connection dialog
If you are writing your own custom Task Scheduler COM Handler based on the ITaskHandler interface, there is a project template available that will stub out the majority of the work to create it in C# and a sample to show a complete one. If running your own code, this model provides much better interaction, control and memory management than running an executable.
Sample Code
There is a help file included with the download that provides an overview of the various classes. There are numerous examples under the "Documentation" tab.
You can perform a number of actions in a single line of code:
// Run a program every day on the local machine TaskService.Instance.AddTask("Test", QuickTriggerType.Daily, "myprogram.exe", "-a arg"); // Run a custom COM handler on the last day of every month TaskService.Instance.AddTask("Test", new MonthlyTrigger { RunOnLastDayOfMonth = true }, new ComHandlerAction(new Guid("{CE7D4428-8A77-4c5d-8A13-5CAB5D1EC734}")));
For many more options, use the library classes to build a complex task. Below is a brief example of how to use the library from C#.
using System; using Microsoft.Win32.TaskScheduler; class Program { staticvoid Main(string[] args) { // Get the service on the local machineusing (TaskService ts = new TaskService()) { // Create a new task definition and assign properties TaskDefinition td = ts.NewTask(); td.RegistrationInfo.Description = "Does something"; // Create a trigger that will fire the task at this time every other day td.Triggers.Add(new DailyTrigger { DaysInterval = 2 }); // Create 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 ts.RootFolder.RegisterTaskDefinition(@"Test", td); // Remove the task we just created ts.RootFolder.DeleteTask("Test"); } } }

Examples Home Page
You can go to these pages for more sample code:Below are some examples of how to use most of the functions of the library:
- Using the editor
- Simple example
- Enumerate all tasks
- Complex example
- XML example
- Fluent example
- Task history example
Using the editor
// Get the service on the local machineusing (TaskService ts = new TaskService()) { // Create a new taskconststring 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 editorForm = new TaskEditDialog(t, true, true); editorForm.ShowDialog(); // Remove the task we just created ts.RootFolder.DeleteTask(taskName); }
Simple example
// Get the service on the local machineusing (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(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 folderconststring 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

XML example
Tasks can be saved or created from scratch in XML and then registered directly as an alternative to setting individual properties.
// Save a Task's XML to a filestring xml = TaskService.Instance.GetTask("\\Temp").Xml; System.IO.File.WriteAllText("localfile.xml", td.XmlText, System.Text.Encoding.Unicode); // Create a Task using XML with user information TaskService.Instance.RootFolder.RegisterTask("NewTask1", xml, TaskCreation.Create, "SYSTEM", null, TaskLogonType.SystemAccount); // Create a Task directly from a file TaskService.Instance.RootFolder.ImportTask("NewTask2", "localfile.xml"); // Load an XML file for editing, change a property, and register TaskDefintion td = TaskService.Instance.NewTask(); td.XmlText = System.IO.File.ReadAllText("localfile.xml"); td.Settings.AllowDemandStart = true; TaskService.Instance.RootFolder.RegisterTaskDefinition("NewTask3", td);
Fluent example
The library also exposes a Fluent syntax for accomplishing most functions. Below are a number of examples.
using (TaskService ts = new TaskService()) { ts.Execute("notepad.exe").WithArguments(@"c:\temp\music.txt").Once().Starting(2013, 11, 11, 11, 0, 0).RepeatingEvery(TimeSpan.FromMinutes(5)).AsTask("Test"); ts.Execute("notepad.exe").Every(2).Days().Starting("12/25/2013 7:00pm").AsTask("Test"); ts.Execute("notepad.exe").Every(3).Weeks().AsTask("Test"); ts.Execute("notepad.exe").OnAll(DaysOfTheWeek.Monday).In(WhichWeek.FirstWeek).Of(MonthsOfTheYear.January).AsTask("Test"); ts.Execute("notepad.exe").InTheMonthOf(MonthsOfTheYear.January).OnTheDays(1, 3, 5).AsTask("Test"); ts.Execute("notepad.exe").OnBoot().AsTask("Test"); ts.Execute("notepad.exe").OnIdle().AsTask("Test"); ts.Execute("notepad.exe").OnStateChange(TaskSessionStateChangeType.ConsoleConnect).AsTask("Test"); ts.Execute("notepad.exe").AtLogonOf("AMERICAS\\dahall").AsTask("Test"); ts.Execute("notepad.exe").AtTaskRegistration().AsTask("Test"); }
Task history example
If you use the TaskEventLog constructor which specifies a remote machine, you will need to use impersonation to logon to an account with privileges to the remote machine before instantiating the TaskEventLog.
TaskEventLog log = new TaskEventLog(task.Path); List<ListViewItem> c = new List<ListViewItem>(100); foreach (TaskEvent item in log) c.Add(new ListViewItem(newstring[] { item.Level, item.TimeCreated.ToString(), item.EventId.ToString(), item.TaskCategory, item.OpCode, item.ActivityId.ToString() }));

Closed Issue: The task has been configured with an unsupported combination of account settings and run time options. [12293]
Hi,
Since I've updated to the latest stable release(2.5.4) I'm getting the following error:
_The task has been configured with an unsupported combination of account settings and run time options. (Exception from HRESULT: 0x80041314)_
This did not happen with version 2.4.2 and lower (doublechecked it)
What happens is:
I'm contacting a Win7 machine but i specify the taskservice to use 1.1 version.
Then i register a task with the serviceaccount.
I've been able to reproduce this error several times
Can you confirm this as a bug?
Code (C#):
```
using (TaskService ts = new TaskService(hostname, null, null, null, true))
{
TaskDefinition tduser = ts.NewTask();
bool newVer = (ts.HighestSupportedVersion >= new Version(1, 2));
tduser.Actions.Add(new ExecAction("cmd", "Do something", null));
tduser.Settings.DisallowStartIfOnBatteries = false;
tduser.Settings.StopIfGoingOnBatteries = false;
tduser.RegistrationInfo.Description = "My Task";
if (newVer) //v2.0
{
tduser.Principal.RunLevel = TaskRunLevel.Highest;
tduser.Settings.AllowDemandStart = true;
}
ts.RootFolder.RegisterTaskDefinition("My Task", tduser, TaskCreation.CreateOrUpdate,

Hi,
After some changes library cannot get data from remote server.
Details: I use win7 and try to get state of task on win2003. TaskService is used with forceV1=true.
Code to reproduce:
```
using (TaskService ts = new TaskService(targetServer2003, user, domain, pwd, true ))
{
List<TaskState> taskList = new List<TaskState>();
foreach (Task task in ts.RootFolder.Tasks)
taskList.Add(task.State);// error occurs here
}
```
Error:
```
The system cannot find the path specified. (Exception from HRESULT: 0x80070003)

For status reading that can be fixed in Task.cs if we use Name instead of path:
```
internal void V1Reactivate()
{
V1Interop.ITask iTask = TaskService.GetTask(TaskService.v1TaskScheduler, Name);
if (iTask != null)
v1Task = iTask;
}

New Post: A password must be supplied
Hi,
New build works fine when you add a new task but does not work with an old task when you try to edit it.
For this case UserId always is not empty and check at Task.cs does not work:

Thank you for doing better testing than me. I have corrected and it will be in the next release.

New Post: A password must be supplied
I have tested again and found a new issue) Sometime unnecessary dialog appears for current user. I don't know how but right now I have two tasks with current user as runner but its name has different cases.
I guess string.Compare(UserId, System.Security.Principal.WindowsIdentity.GetCurrent().Name) should compare with ignore case (StringComparison.OrdinalIgnoreCase).
Thank you.
