.NET Windows Service Scheduler

Introduction

This program lets you schedule your Windows service to run at user configured intervals. It's inspired by this article by Andy Brummer.

The scheduler lets you schedule your Windows service code in one of the following three ways:

1. Once a day
2. Once a week
3. Once a month

If you want to schedule multiple times, instantiate as many Scheduler objects you want.

It mails any exceptions to the user supplied email addresses. If the user chooses not to email, exceptions will be logged to the event log under "Service Scheduler".

Usage

Add a reference to the Scheduler.dll:

using Sathish.ServiceScheduler;
Scheduler sch = new Scheduler("MyServiceName");
MailConfiguration mailConfig = new MailConfiguration(yourmail@gmail.com, 
    "admin@yourcompany.com", "Service Down", "localhost", "MyServiceName");

//If you don't do this, all your exceptions will be logged to the event log 
//under "Service Scheduler"
sch.MailComponent = mailConfig; 

//Subscribe to the schedulerFired event.
//I used EventHandler because it was straightforward. 
//You can write your own delegate signature.
sch.SchedulerFired += new EventHandler(YourServiceMethod); 

//Schedule weekly or monthly or daily
sch.ScheduleWeekly(DayOfWeek.Friday, "3:00 AM");

//sch.ScheduleMonthly(4, "6:20 PM"); //4 is 4th day of the month.
//sch.ScheduleDaily("4:00 AM");

The program checks if your mail infrastructure is in place. If not, it throws an exception.

And yes, it also takes care of 30/31/28/29 day months. So if you said...

sch.ScheduleMonthly(31, "4:00 AM") 

... and the month had only 30 days, the program adjusts the difference and the scheduler fires on the last day (in this case 30^th) of the month.

I haven't had the time to test it thoroughly. I will do it in the coming days and update any revisions. If any of you find anything amiss, please let me know at mailsash@gmail.com.

If you make enhancements, do send me a copy/link.
