Closed Unassigned: Code to check the staus of scheduled task in remote machine and fire email [11029]

dahall — Sun, 19 May 2013 04:41:00 GMT

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 System.Diagnostics;
using System.Net;
using System.Net.Mail;
using System.Data.SqlClient;
using System.Data;
using System.Devices;
//using System.Devices.RemoteDeviceManager;
//using System.Diagonistics.EventLog;

namespace TaskSchedulerRemote
{
class Program
{
//TaskService 01_server = getTaskService("\\\\123.122.222.222", "administrator", "domain1", "pwd0", true);
//TaskService 02_server = getTaskService("\\\\123.122.222.222", "administrator", "domain2", "pwd1", true);
static void Main(string[] args)
{
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;
case TaskState.Disabled:
Console.WriteLine("Disabled");
break;
case TaskState.Running:
Console.WriteLine("Running");
break;
}
Thread.Sleep(10000);
//MailMessage Msg = new MailMessage();
//MailAddress fromMail = new MailAddress("emailid");
//// Sender e-mail address.
//Msg.From = fromMail;
//// Recipient e-mail address.
//Msg.To.Add(new MailAddress("emailid"));
//Msg.Priority = MailPriority.High;
//// Subject of e-mail

//Msg.Subject = "Scheduled Task Status Report:" + System.DateTime.Now;

//Msg.Body += "<html><body><Table><tr><td>Hi All,</td></tr><tr><td>Please find below the status report of schduled task :</td></tr></Table></body></html><html><body>";
//Msg.Body += "<html><body><Table><tr><td>Regards,</td></tr><tr><td></td></tr><tr><td></td></tr>" +
//"<tr><td><b>NOTE: This is an automated mail. Please, do not reply.</b> </td></tr></table></body></html>";
//Msg.IsBodyHtml = true;
//string sSmtpServer = "";
//sSmtpServer = "mailservername";
//SmtpClient a = new SmtpClient();
//a.Host = sSmtpServer;
//a.EnableSsl = false;
//try
//{
// Console.WriteLine("Sending mail...");
// a.Send(Msg);
// Console.WriteLine("Mail was sent successfully!");
//}
//catch (Exception ep)
//{
// Console.WriteLine("failed to send mail:");
// 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.

Comments: ** Comment from web user: dahall **

There is a potential race condition when multiple instances of the COM object access the same task. I handle this exception in the library, but the native application does not. This is the error you are seeing. The only way to avoid it is to not access the same task through the library that is being viewed in the native app.

This error is not coming from this library. Are you seeing this error from the Windows Task Scheduler application? If so, then please contact Microsoft for support.

Please provide references to any code that is running, how you have created the task, how you're accessing the task, etc. The information you have provided is insufficient for me to act on.

I received the following exception when calling GetRunningTasks:

"The function attempted to use a name that is reserved for use by another transaction. (Exception from HRESULT: 0x80071A90)"

Here is the call stack:
at Microsoft.Win32.TaskScheduler.V2Interop.TaskSchedulerClass.GetRunningTasks(Int32 flags)
at Microsoft.Win32.TaskScheduler.TaskService.GetRunningTasks(Boolean includeHidden) in TaskService.cs:line 113

Section of code (line 113 is the return statement):
```
public RunningTaskCollection GetRunningTasks(bool includeHidden)
{
return v2 ? new RunningTaskCollection(this, v2TaskService.GetRunningTasks(includeHidden ? 1 : 0)) : new RunningTaskCollection(this);
}
```
The next time I called GetRunningTasks it succeeded but I'm concerned this exception is going to happen again.

Thanks,

I ran this test with MMC up and found the same error. I have traced the problem back to the Microsoft native library. I will be posting the issue as a concurrency problem to Microsoft.

Closed Issue: Unsetting a trigger's end boundary in UI does not reset the trigger's EndBoundary property [10778]

dahall — Mon, 04 Feb 2013 20:20:40 GMT

using Microsoft.Win32.TaskScheduler.dll v1.9.2

Let's assume I configure a scheduled task this way, with an end boundary set on the trigger.
I get the following output :

```
Name : test
Enabled : True
LastRunTime : 01/01/0001 00:00:00
LastTaskResult : 0
State : Unknown
IsActive : False
NextRunTime : 01/01/0001 00:00:00
Should have run : 22/01/2013 09:00:00
Trigger #1:
Start boundary : 15/01/2013 09:00:00
End boundary : 22/01/2013 00:00:00
```

notice that IsActive and NextRunTime are correct as the trigger is deactivated because of the passed end boundary date

now when I unset this end boundary date from Trigger#1 :

```
Name : test
Enabled : True
LastRunTime : 01/01/0001 00:00:00
LastTaskResult : 0
State : Unknown
IsActive : False
NextRunTime : 30/01/2013 09:00:00
Should have run : 22/01/2013 09:00:00
Trigger #1: à 09:00 tous les jours, début : 15/01/2013
Start boundary : 15/01/2013 09:00:00
End boundary : 22/01/2013 00:00:00
```

IsActive still returns False, EndBoundary still returns the same date (and it shouldn't)
but NextRunTime is correct !

Hope this helps

Hi, thanks for answering
Indeed when using your task editor API, things work fine.
I am using Windows XP standard scheduled tasks UI.

Check the attached screenshot (sorry, in French) : I unchecked "expires" in the Win XP UI and it's still set in TaskDialog (which is "normal" as the expiration date is still set)

Guess the problem lies in Win (XP at least, I have no other version to test)...

I just put together a very simple test for your issue and cannot repeat your results. Here's the code:
```
const string taskName = "Test";
TaskDefinition td = ts.NewTask();
td.Triggers.Add(new DailyTrigger() { StartBoundary = new DateTime(2013, 1, 15, 9, 0, 0), EndBoundary = new DateTime(2013, 1, 22, 9, 0, 0) });
td.Actions.Add(new ExecAction("notepad.exe"));
Task t = ts.RootFolder.RegisterTaskDefinition(taskName, td, TaskCreation.CreateOrUpdate, null, null, TaskLogonType.InteractiveToken);
output.Write("***********************\r\nName: {0}\r\nEnabled: {1}\r\nLastRunTime: {2}\r\nState: {3}\r\nIsActive: {4}\r\nNextRunTime: {5}\r\nShouldHaveRun: {6}\r\nTriggerStart: {7}\r\nTriggerEnd: {8}\r\n",
t.Name, t.Enabled, t.LastRunTime, t.State, t.IsActive, t.NextRunTime, t.LastRunTime, t.Definition.Triggers[0].StartBoundary, t.Definition.Triggers[0].EndBoundary);
TaskEditDialog dlg = new TaskEditDialog(t);
if (dlg.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
t = dlg.Task;
output.Write("***********************\r\nName: {0}\r\nEnabled: {1}\r\nLastRunTime: {2}\r\nState: {3}\r\nIsActive: {4}\r\nNextRunTime: {5}\r\nShouldHaveRun: {6}\r\nTriggerStart: {7}\r\nTriggerEnd: {8}\r\n",
t.Name, t.Enabled, t.LastRunTime, t.State, t.IsActive, t.NextRunTime, t.LastRunTime, t.Definition.Triggers[0].StartBoundary, t.Definition.Triggers[0].EndBoundary);
}
```
When I run it the first time, I get:
```
Name: Test
Enabled: True
LastRunTime: 1/1/0001 12:00:00 AM
State: Ready
IsActive: False
NextRunTime: 1/1/0001 12:00:00 AM
ShouldHaveRun: 1/1/0001 12:00:00 AM
TriggerStart: 1/15/2013 9:00:00 AM
TriggerEnd: 1/22/2013 9:00:00 AM
```
When I open the dialog, uncheck the checkbox for the trigger's "Expires" item and click OK, I get:
```
Name: Test
Enabled: True
LastRunTime: 1/1/0001 12:00:00 AM
State: Ready
IsActive: True
NextRunTime: 1/30/2013 9:00:00 AM
ShouldHaveRun: 1/1/0001 12:00:00 AM
TriggerStart: 1/15/2013 9:00:00 AM
TriggerEnd: 12/31/9999 11:59:59 PM
```
