Hello,
im hoping to get some help on my problem.
im trying to make something that will change the password of a task if it has defined a username/password
if possible i would like to do if task has username admin in it then change password to xx
i already found the way how to update the task, only i need to find a way to list all tasks and see under what user they are running
i hope i was able to explain myself well enough.
Regards,
Reinier van Dijk
Try source code version 78863.
Update, in source code version 78863 and soon in release 1.8.3, XML input and output are supported for V1 instances.

Use the Enumerate all task example (http://taskscheduler.codeplex.com/wikipage?title=Examples#enum) and then use the Task.TaskDefinition.Principal.UserId property to get the username. Once you have that, you can use TaskFolder.RegisterTaskDefinition method to re-register the task with a different set of credentials.
Thanks David! Problems fixed, both in Win 7 and Win XP. Really appreciate it.
Thanks for the reply, this was exactly what i needed!
Hi,
I'm getting errors when trying to create or delete a tasks for the current user. I have not been able to repo this on my machine at all. However, I can repo this on any test machine (i.e. no VS installed and user is not running with admin permissions).
System.UnauthorizedAccessException: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)) at Microsoft.Win32.TaskScheduler.V2Interop.ITaskFolder.RegisterTaskDefinition(String Path, ITaskDefinition pDefinition, Int32 flags, Object UserId, Object password, TaskLogonType LogonType, Object sddl) at Microsoft.Win32.TaskScheduler.TaskFolder.RegisterTaskDefinition(String Path, TaskDefinition definition, TaskCreation createType, String UserId, String password, TaskLogonType LogonType, String sddl) at Microsoft.Win32.TaskScheduler.TaskFolder.RegisterTaskDefinition(String Path, TaskDefinition definition)
Here's my code:
using (var ts = new TaskService()) { var taskDef = ts.NewTask(); taskDef.RegistrationInfo.Description = string.Format( Resources.Scheduled_Task_Desc_Format, this.TargetEntity.FriendlyName ); taskDef.Triggers.Add(GetTrigger(_interval)); taskDef.Actions.Add( new ExecAction( Assembly.GetEntryAssembly().Location, "-s " + GetSyncFlowName(this.TargetEntity) ) ); ts.RootFolder.RegisterTaskDefinition(taskName, taskDef); }
for deletes
var taskFilter = new Regex( string.Concat("^", taskName, "$"), RegexOptions.Singleline | RegexOptions.Compiled ); // Find the existing instance of the task.. var olTask = ts.RootFolder.GetTasks(taskFilter).FirstOrDefault(); if (olTask != null) { ts.RootFolder.DeleteTask(taskName); }
Hi,
I want to create a report which will contain task start time and task end time of all the tasks. Can any body help in this regard.
Thanks

Hi
I am using Windows Server 2003 from where I want to connect Window Server 2008 task scheduler in my web application. I tried to do following but wont work. I work for locally (2003) but wont for remote server (2008)
e.g.
TaskService m_TaskService = new TaskService(@"\\testServer2008", "testUser", "testDomain", "testPassword", true);
Logon failure: unknown user name or bad password
We tried different combination, but it wont work for remote server. Does I missing something? Please provide guide lines to me.
Regards
Ajay
Following works for me in Window Server 2003 and Windows Server 2008
TaskService ts = new TaskService();
Version ver = ts.HighestSupportedVersion;
bool newVer = (ver >= new Version(1, 2));
TaskFolder tf = ts.RootFolder;
Hope it will help full?
Best Regards
Ajay
Hi
TaskService ts = new TaskService();
Version ver = ts.HighestSupportedVersion;
bool newVer = (ver >= new Version(1, 2));
TaskFolder tf = ts.RootFolder;
This might works?
Ajay
Check these two links for information about rights required on systems to register and delete tasks:
You likely will need to review each task's event history for that information. Look at using the TaskEventLog class in the TaskSchdulerEditor assembly.
Windows Server 2003 only has the 1.0 library locally. It will only connect to other Windows 2000 and 2003 servers. Windows Server 2003 R2 and later have the 2.0 libraries and can connect to either 1.0 or 2.0 capable servers.
Thanks Dahall.
Does this mean that a application opened by a standard user would not be able to even schedule a taks that does not require elevated permissions?
I've verified that the standard user can schedule and delete tasks by going to Scheduled Tasks in Control Panel. The task needs to execute only for the current user and in the current user's context.
