New Post: Unhandled Exception in Wizard

Hi dahall, I'm having the same problem and seems the posted code doesn't work.

Here is my code using taskscheduler-78172 running on Windows XP Professional 2002 SP3.

            using(TaskService ts = new TaskService())
            {
                TaskDefinition td = ts.NewTask();
                TaskSchedulerWizard wizard = new TaskSchedulerWizard();
                wizard.Initialize(ts, td);
                wizard.RegisterTaskOnFinish = true;
                wizard.ShowDialog();
            }

When I come to Security Options page, user account is automatically displayed, and I click Next button, popup dialog shows to input user name and password.

After I input them, I got this exception:

System.NullReferenceException was unhandled
