c# - Get an instance of the scheduler that is being run on a Windows service

Question

Let us say I have prepared my Quartz.NET as a Windows service and it is currently being run (with an ADOJobStore running on Sqlite). I need to take control of this service on my Windows application so I can stop it, start it, add and remove jobs from it, etc. How can I get an instance of this scheduler?

Sorry if it sounds like a simple question for you, but the documentation on Quartz.NET seems nowhere near enough. There are only a few people who know about it and they already have their lives to live.

Update: quartz.config file of my service

# You can configure your scheduler in either <quartz> configuration section
# or in quartz properties file
# Configuration section has precedence

quartz.threadPool.type = Quartz.Simpl.SimpleThreadPool, Quartz
quartz.threadPool.threadCount = 10
quartz.threadPool.threadPriority = Normal

# job initialization plugin handles our xml reading, without it defaults are used
quartz.plugin.xml.type = Quartz.Plugin.Xml.XMLSchedulingDataProcessorPlugin, Quartz
quartz.plugin.xml.fileNames = ~/quartz_jobs.xml

quartz.scheduler.exporter.type = Quartz.Simpl.RemotingSchedulerExporter, Quartz
quartz.scheduler.exporter.port = 555
quartz.scheduler.exporter.bindName = QuartzScheduler
quartz.scheduler.exporter.channelType = tcp
quartz.scheduler.exporter.channelName = httpQuartz

The code I am using on my program to get the scheduler:

NameValueCollection properties = new NameValueCollection();
properties["quartz.scheduler.instanceName"] = "RemoteClient";

// set thread pool info
properties["quartz.threadPool.type"] = "Quartz.Simpl.SimpleThreadPool, Quartz";
properties["quartz.threadPool.threadCount"] = "10";
properties["quartz.threadPool.threadPriority"] = "Normal";

// set remoting expoter
properties["quartz.scheduler.proxy"] = "true";
properties["quartz.scheduler.proxy.address"] = "tcp://127.0.0.1:555/QuartzScheduler";

ISchedulerFactory sf = new StdSchedulerFactory(properties);
IScheduler sched = sf.GetScheduler();

My service is installed and is in Started state and it is log on as a "Local System Account" and it is able interact with the desktop.

Your service can expose the scheduler by modifying the config file:

<add key="quartz.scheduler.exporter.type" value="Quartz.Simpl.RemotingSchedulerExporter, Quartz" />
<add key="quartz.scheduler.exporter.port" value="555" />
<add key="quartz.scheduler.exporter.bindName" value="QuartzScheduler" />
<add key="quartz.scheduler.exporter.channelType" value="tcp" />
<add key="quartz.scheduler.exporter.channelName" value="httpQuartz" />

Your Windows app can then accesss it with the appropriate settings:

        //you can put these in a config file too.
        NameValueCollection properties = new NameValueCollection();
        properties["quartz.scheduler.instanceName"] = "RemoteClient";

        // set thread pool info
        properties["quartz.threadPool.type"] = "Quartz.Simpl.SimpleThreadPool, Quartz";
        properties["quartz.threadPool.threadCount"] = "5";
        properties["quartz.threadPool.threadPriority"] = "Normal";

        // set remoting expoter
        properties["quartz.scheduler.proxy"] = "true";
        properties["quartz.scheduler.proxy.address"] = "tcp://127.0.0.1:555/QuartzScheduler";

        ISchedulerFactory sf = new StdSchedulerFactory(properties);
        IScheduler sched = sf.GetScheduler();

The quartz.net master contains really good examples that you won't find in the documentation.
