Trigger that runs every hour forever

[dpra]

Hi there,

I need a trigger that fires every hour forever, which I'm going to use in a Windows Service. From http://quartznet.sourceforge.net/migration_guide.html
I got the following

ITrigger trigger = TriggerBuilder.Create()
                        .WithIdentity("trigger1", "group1")
                        .StartAt(DateBuilder.FutureDate(1, IntervalUnit.HOURS))
                        .WithSimpleSchedule(x => x.RepeatHourlyForever())
                        .ModifiedByCalendar("holidays")
                        .Build();


What is 'x' here? It doesn't resolve. I'm not a c# pro and I hadn't come across a declaration using '=>' 
Is there a way to declare the trigger without using 'x'
and where is the documentation for 2.0 located apart form http://quartznet.sourceforge.net/apidoc/2.0/html/webframe.html
as I couldn't find 'WithSimpleSchedule' there.

Thank in advance!

Hi

Have you tried with a cron job?

I'm quite new to this but i think something like this would do it:

ICronTrigger trigger = (ICronTrigger)TriggerBuilder.Create()

                                                .WithIdentity("trigger1", "group1")

                                                .WithCronSchedule("* * 0/1 * * ?")

                                                .Build();

Thanks John, what interval is WithCronSchedule("* * 0/1 * * ?") scheduling the job?

I ran the program and it is running almost every second. I need it to run once an hour. Is there is a place where I can get documentation for the API?

Thanks!

Hi,

    The following link explains CRON trigger "http://quartz-scheduler.org/documentation/quartz-2.x/tutorials/tutorial-lesson-06" and following link helps us to build cron trigger "http://www.cronmaker.com/"

I found the following in the 2.0 doc. Thanks for letting me know ICronTrigger John!

==========================

For those unfamiliar with "cron", this means being able to create a firing schedule such as: "At 8:00am every Monday through Friday" or "At 1:30am every last Friday of the month".

The format of a "Cron-Expression" string is documented on the CronExpression class.

Here are some full examples:

Expression		Meaning
"0 0 12 * * ?"" />		Fire at 12pm (noon) every day" />
"0 15 10 ? * *"" />		Fire at 10:15am every day" />
"0 15 10 * * ?"" />		Fire at 10:15am every day" />
"0 15 10 * * ? *"" />		Fire at 10:15am every day" />
"0 15 10 * * ? 2005"" />		Fire at 10:15am every day during the year 2005" />
"0 * 14 * * ?"" />		Fire every minute starting at 2pm and ending at 2:59pm, every day" />
"0 0/5 14 * * ?"" />		Fire every 5 minutes starting at 2pm and ending at 2:55pm, every day" />
"0 0/5 14,18 * * ?"" />		Fire every 5 minutes starting at 2pm and ending at 2:55pm, AND fire every 5 minutes starting at 6pm and ending at 6:55pm, every day" />
"0 0-5 14 * * ?"" />		Fire every minute starting at 2pm and ending at 2:05pm, every day" />
"0 10,44 14 ? 3 WED"" />		Fire at 2:10pm and at 2:44pm every Wednesday in the month of March." />
"0 15 10 ? * MON-FRI"" />		Fire at 10:15am every Monday, Tuesday, Wednesday, Thursday and Friday" />
"0 15 10 15 * ?"" />		Fire at 10:15am on the 15th day of every month" />
"0 15 10 L * ?"" />		Fire at 10:15am on the last day of every month" />
"0 15 10 ? * 6L"" />		Fire at 10:15am on the last Friday of every month" />
"0 15 10 ? * 6L"" />		Fire at 10:15am on the last Friday of every month" />
"0 15 10 ? * 6L 2002-2005"" />		Fire at 10:15am on every last Friday of every month during the years 2002, 2003, 2004 and 2005" />
"0 15 10 ? * 6#3"" />		Fire at 10:15am on the third Friday of every month" />

Pay attention to the effects of '?' and '*' in the day-of-week and day-of-month fields!

Hi Drpa

I Just wanted to answer the question about what the 'x' is .

the 'x' statement is called a lambda expression, for more information about that you can check out this link:

Lambda Expressions C#

The Lambda expressions is mostly used for Linq To SQL/Objects/Entities for filtering ect.

I hope this helps
