I have to schedule an Apex class, using a custom schedule page. I have to write the CRON EXPRESSION based on the requirements like :
It should be scheduled between specific days (like, we would have a start date and an end date) along with on specific days of the week (like, on Saturday or Sunday); i.e. something like Schedule an apex class on Sundays between 12/05/2016 to 12/06/2016.
Please help.Thanks in advance.
Hi Souravmoy Gorai, /* for your above requirment execute this code in your class or where you want to execute scheduled. */ //Bind your Start Date and End Date Date StartDate = System.today(); Date EndDate = System.today().addDays(30); //Set Week Name which is you received from page String weekName = 'Sunday'; //Caculating the differnece between days. Integer daysBetween = startDate.daysBetween(endDate); startDate = startDate.addDays(-1); //Schedule class Name which you want to be execute ScheduleClass c = new ScheduleClass(); for(Integer i = 0 ;i < daysBetween ;i++){ Date newDate = startDate.addDays(i); Datetime dt = datetime.newInstance(newDate.year(), newDate.month(),newDate.day()); String dayOfWeek= dt.format('EEEE'); if(dayOfWeek.toLowerCase() == weekName.toLowerCase()){ System.debug('Inside Day --->' + dayOfWeek); String sch = '0 0 0 '+ newDate.day() + ' ' + newDate.month() + ' ? ' + newDate.year(); System.schedule('Visit unique' + i + newDate, sch, c); i = i + 6; } }If this post solves your problem kindly mark it as solution.Thanks.
