New Post: Exception thrown in case of Trigger type "TimeTrigger"

Hi,

I am trying to set task to be scheduled only once. Thus, I am using TimeTrigger , but I get the exception at

ts.RootFolder.RegisterTaskDefinition(Curr_Task.Name, Curr_Task.Definition, TaskCreation.CreateOrUpdate, str_username, str_password, TaskLogonType.Password);

Exception Details :-

Stack Trace :
