Create and Control Windows services--not a Slap Shot, but almost as fast[rank: advanced]

Services|window| Advanced Not a Slap Shot, but almost as Fast
Creating the service using. NET is fairly straightforward. Use the. NET Framework ' s system.serviceprocess namespace and four classes within It:servicebase, ServiceInstaller, Se Rviceprocessinstaller, and ServiceController. These classes provide most of the functionality your need to create a service (for the Figure 1).

The ServiceBase class defines methods a derived class can override so the Service control Manager can control a service-in Cluding OnStart (), OnStop (), OnPause (), and OnContinue (). Furthermore, a service can override the Oncustomcommand () function to carry out specific operations to it sent Cally by a external service controller (more in this later). Implementing these functions in your derived class gives your necessary of a service:

protected override void OnStart (string[) args)
{
}
protected override void OnStop ()
{
}
protected override void OnPause ()
{
}
protected override void OnContinue ()
{
}
Allow your service to begin execution by defining a entry point into your executable, as and would with a regular ble. Within the Main () function, create a instance of your class and call the Run () method defined by the ServiceBase base CLA Ss. If you are want your executable to support multiple services, create a array of ServiceBase objects with each element CORRESP Onding to one of your defined services:

static void Main ()
{
System.serviceprocess.servicebase[] myservices;

MyServices = new system.serviceprocess.servicebase[] {new Service1, New Service2 ()};

System.ServiceProcess.ServiceBase.Run (myservices);
}
Note this Run () does not start your service. In the "other words", you won ' t receive a OnStart () call from the Run () method itself. As I mentioned before, the service control Manager controls the service by calling the necessary controlling.
