Windows task scheduler to execute tasks in seconds

Question

I\'m looking for an open source/free task scheduler for Windows 7 (development machine) that will allow me to schedule tasks (HTTP requests to a web service) to run every x

Answer 1

Short explanation: Main program starts a service process that will stay active in memory and will periodically activate a job – do something.

1. Create a class that extends System.ServiceProcess.ServiceBase class
2. Implement at least methods OnStart and OnStop
3. Start and use Quartz.NET scheduler in OnStart to run tasks periodically

Here is my template C# solution for a Windows service and a Linux demon in .NET/Mono https://github.com/mchudinov/ServiceDemon And a short blogpost about it

    class Program
    {
        public static void Main(string[] args)
        {
            ServiceBase[] ServicesToRun;
            ServicesToRun = new ServiceBase[] { new ServiceDemon.Service() };
            ServiceBase.Run(ServicesToRun);
        }
    }

    public class Service : ServiceBase
    {
        static IScheduler Scheduler { get; set; }

        protected override void OnStart(string[] args)
        {
            StartScheduler();
            StartMyJob();
        }

        protected override void OnStop()
        {
            Scheduler.Shutdown();
        }

        void StartScheduler()
        {
            ISchedulerFactory schedFact = new StdSchedulerFactory();
            Scheduler = schedFact.GetScheduler();
            Scheduler.Start();
        }

        void StartMyJob()
        {
            var seconds = Int16.Parse(ConfigurationManager.AppSettings["MyJobSeconds"]);
            IJobDetail job = JobBuilder.Create()
                .WithIdentity("MyJob", "group1")
                .UsingJobData("Param1", "Hello MyJob!")
                .Build();

            ITrigger trigger = TriggerBuilder.Create()
                .WithIdentity("MyJobTrigger", "group1")
                .StartNow()
                .WithSimpleSchedule(x => x.WithIntervalInSeconds(seconds).RepeatForever())
                .Build();

            Scheduler.ScheduleJob(job, trigger);
        }
    }

    public class MyJob : IJob
    {
        public void Execute(IJobExecutionContext context)
        {
            JobDataMap dataMap = context.JobDetail.JobDataMap;
            log.Info(dataMap["Param1"]);
        }
    }
