quartz.net simple example as per the time given - quartz-scheduler

Question

I am new to quartz.net. I want to build a simple window based application which scheduled the task. Suppose I have 4 task ans it start and end time
Example
Breakfast ; 8:00;8:30
Lunch;13:00;13:30
dinner;19:30;20:00
Now I want when I click on button at 8:00 AM a message box should appear with a text "breakfast started!!!" at 8:30 AM again a message box should appear with a text as "Breakfast end!!!" and so on.
I had gone through tutorial. But confuse how to proceed. Can any one help me out?
EDIT
Is it possible to use one job and one triggers for this?
IScheduler scheduler = StdSchedulerFactory.GetDefaultScheduler();
for (int i = 0; i < listBox1.Items.Count; i++)
{
string[] strArr = Regex.Split(listBox1.Items[i].ToString(), #";", RegexOptions.Multiline);
// define the job and tie it to our HelloJob class
IJobDetail jobStart = JobBuilder.Create<HelloJob>()
.WithIdentity("job" + i, "group1") // name "myJob", group "group1"
.StoreDurably()
.UsingJobData("jobSays", strArr[0].ToUpper().Trim() + " " + "starts")
.Build();
string[] ArrStart = strArr[1].Trim().Split(':');
ITrigger triggerstart = TriggerBuilder.Create()
.WithIdentity("trigger" + i, "group1")
.WithSchedule(CronScheduleBuilder.DailyAtHourAndMinute(Convert.ToInt32(ArrStart[0]), Convert.ToInt32(ArrStart[1])))
// .WithSimpleSchedule(x => x.WithMisfireHandlingInstructionIgnoreMisfires()
.ForJob(jobStart)
.Build();
// .WithSchedule(CronScheduleBuilder.CronSchedule("0 4 06 1/1 * ? *"))
// Tell quartz to schedule the job using our trigger
scheduler.ScheduleJob(jobStart, triggerstart);
scheduler.Start();
string[] Arrend = strArr[2].Trim().Split(':');
IJobDetail jobend = JobBuilder.Create<HelloJob>()
.WithIdentity("job1" + i, "group1")
.StoreDurably()
.UsingJobData("jobSays", strArr[0].ToUpper().Trim() + " " + "end")
.Build();
ITrigger triggerend = TriggerBuilder.Create()
.WithIdentity("trigger1" + i, "group1")
.WithSchedule(CronScheduleBuilder.DailyAtHourAndMinute(Convert.ToInt32(Arrend[0]), Convert.ToInt32(Arrend[1])))
// .WithSimpleSchedule(x => x.WithMisfireHandlingInstructionIgnoreMisfires()
.ForJob(jobend)
.Build();
scheduler.ScheduleJob(jobend, triggerend);
scheduler.Start();
}
}
catch (SchedulerException se)
{
Console.WriteLine("Scheduler Exception : " + se);
}
}
public class HelloJob : IJob
{
public void Execute(IJobExecutionContext context)
{
JobKey key = context.JobDetail.Key;
JobDataMap dataMap = context.JobDetail.JobDataMap;
string jobSays = dataMap.GetString("jobSays");
MessageBox.Show(jobSays);
}
}

You can schedule a job as follows and use this simple example:
IScheduler scheduler = StdSchedulerFactory.GetDefaultScheduler();
IJobDetail job = JobBuilder.Create<MealAlertJob>()
.WithIdentity("mealJob", "mealJobGroup")
.Build();
ITrigger trigger = TriggerBuilder.Create()
.WithIdentity("breakfastStartTrigger", "mealTriggerGroup")
.WithSchedule(CronScheduleBuilder.DailyAtHourAndMinute(8, 0))
.ForJob(job)
.Build();
ITrigger trigger1 = TriggerBuilder.Create()
.WithIdentity("breakfastEndTrigger", "mealTriggerGroup")
.WithSchedule(CronScheduleBuilder.DailyAtHourAndMinute(8, 30))
.ForJob(job)
.Build();
scheduler.ScheduleJob(job, trigger);
scheduler.ScheduleJob(trigger1);
scheduler.Start();
You should implement your logic (let's say showing a message box) in your job class's "Execute" method.
Defining multiple triggers for your job results in multiple execution. In the job class for example "MealAlertJob" you may check the time and show an alert based on it.
In the above example you can add more triggers for the other four times (lunch start/end and dinner start/end).
public class MealAlertJob : IJob
{
public void Execute(IJobExecutionContext context)
{
var now = DateTime.Now;
var hour = now.Hour;
var minute = now.Minute;
if (hour == 8 && minute == 0)
System.Windows.Forms.MessageBox.Show("Breakfast started!!!");
//and so on....
}
}
or something like this.
