Daily task with SessionStateChangeTrigger is giving COMException: '(11,27):Duration:PT15M'

[kondareddy]

I want to create app update scheduled task which run daily once when system is locked. I have attempted with below code but I am getting "System.Runtime.InteropServices.COMException: '(11,27):Duration:PT15M'"

What I am doing wrong here? Any help please?

// Create a new task definition for the local machine and assign properties TaskDefinition td = TaskService.Instance.NewTask(); td.RegistrationInfo.Description = "This keeps app upto date with latest updates.";

// Add a trigger that, that runs every day at 5 AM var todayDate = DateTime.Now.ToString("yyyy-MM-dd") + " 05"; var startDate = DateTime.ParseExact(todayDate, "yyyy-MM-dd HH", System.Globalization.CultureInfo.InvariantCulture); //// session locked SessionStateChangeTrigger st = new SessionStateChangeTrigger { StateChange = TaskSessionStateChangeType.SessionLock }; st.Delay = TimeSpan.FromMinutes(5); st.StartBoundary = startDate.AddDays(1);
st.Repetition.Interval = TimeSpan.FromDays(1); st.Repetition.Duration = TimeSpan.FromMinutes(15); st.Repetition.StopAtDurationEnd = true; td.Triggers.Add(st); //td.Principal.RunLevel = TaskRunLevel.Highest;

//Create an action that will launch Notepad whenever the trigger fires td.Actions.Add(new ExecAction(@"c:\program data\app\app.exe", "/SilentInstall")); td.Settings.WakeToRun = true; td.Settings.DisallowStartIfOnBatteries = false; TaskService.Instance.RootFolder.RegisterTaskDefinition("appUpdate", td);

The value for Interval must be less than or equal to the value for Duration when registering the task. I think you have the meaning of the two switched.

Also, to make the system work less for the StartBoundary, use st.StartBoundary = DateTime.Today.AddDays(1).AddHours(5);. Then you can ignore all the work parsing for startDate.

To be more brief, you could construct st as follows:

td.Triggers.Add(new SessionStateChangeTrigger(TaskSessionStateChangeType.SessionLock) { Delay = TimeSpan.FromMinutes(5),
   StartBoundary = DateTime.Today.AddDays(1).AddHours(5), Repetition = new RepetitionPattern(TimeSpan.FromMinutes(15),
   TimeSpan.FromDays(1), true) });

Thanks for reply. I have attempted like below but - got below exception "(46,4):UserId:" - Any Idea what's the mistake here?

var st = new SessionStateChangeTrigger(TaskSessionStateChangeType.SessionLock) { Delay = TimeSpan.FromMinutes(5), StartBoundary = DateTime.Today.AddDays(1).AddHours(5), Repetition = new RepetitionPattern(TimeSpan.FromMinutes(15), TimeSpan.FromDays(1), true) }; // Register the task in the root folder of the local machine const string taskName = "AppUpdate"; Task td = TaskService.Instance.AddTask(taskName, st, new ExecAction(@"c:\program data\jmb\app.exe", "/SilentInstall"), "This keeps app upto date with latest updates.");

Hm. Try using String.Empty as the second parameter to the SessionStateChangeTrigger constructor.

Thanks for reply. Can I run only once task with below code? even though system got locked multiple time - want to run only once? is that possible?

var st = new SessionStateChangeTrigger(TaskSessionStateChangeType.SessionLock) { Delay = TimeSpan.FromMinutes(5), StartBoundary = DateTime.Today.AddDays(1).AddHours(5), Repetition = new RepetitionPattern(TimeSpan.FromDays(1), TimeSpan.FromDays(1), true) };

This will run starting the next day at 5:00 a.m., 5 minutes after the system is locked, and then will repeat one time, 24 hours later. Is that what you were expecting?

[kondareddy]

No - happening multiple times - for each unlock // Add a trigger that starts from every day at 5 AM var st = new SessionStateChangeTrigger(TaskSessionStateChangeType.SessionLock) { Delay = TimeSpan.FromMinutes(5), StartBoundary = DateTime.Today.AddDays(1).AddHours(5), Repetition = new RepetitionPattern(TimeSpan.FromDays(1), TimeSpan.FromDays(1), true) };

st.UserId = Environment.UserName; td.Triggers.Add(st); td.Settings.RunOnlyIfNetworkAvailable = true; td.Settings.StartWhenAvailable = true;

Just to be clear, there are 5 system events for each task run (129,100,200,201,102). From the screenshot, it appears that the system was locked at 5:25:22 and 5:38:19. Is that the case? Let me rephrase what I said earlier: The task will run 5 minutes after each time the system is locked after the next day at 5:00 a.m. and then will repeat one time, 24 hours later. Please clarify or provide more of the system log with details about when the system was actually locked.

Also, save a line of code and provide the user in the constructor: new SessionStateChangeTrigger(TaskSessionStateChangeType.SessionLock, Environment.UserName).

[kondareddy]

Thanks for prompt replies. The task will run 5 minutes after each time the system is locked after the next day at 5:00 a.m. and then will repeat one time, 24 hours later. How can make it run only once per day - starting from tomorrow Please clarify or provide more of the system log with details about when the system was actually locked. Do you want event viewer as logs?

[dahall]

If you just need a task to run every day at 5 a.m. starting tomorrow, then just use:

td.Triggers.Add(new DailyTrigger(1) { StartBoundary = DateTime.Today.AddHours(24 + 5) });

[kondareddy]

So with below code with/with-out repetitions - task will run every time system is locked? Please confirm?

var st = new SessionStateChangeTrigger(TaskSessionStateChangeType.SessionLock) { Delay = TimeSpan.FromMinutes(5), StartBoundary = DateTime.Today.AddMinutes(1), };

[dahall]

Yes, 5 minutes after every lock.

Thanks - we are good to close
