Windows Service App

To Create a Windows Service App,

1.Start Visual C# (Express)

2.Create New Project (Empty Project) + Add Reference (System.ServiceProcess, System.Configuration, System.Configuration.Install)

3.Create a Service Class

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Diagnostics;
using System.ServiceProcess;

namespace ServiceApp
{
    class MyService : ServiceBase
    {
        public MyService(string[] args)
        {
            this.ServiceName = "MyService.Application";
            this.EventLog.Log = "Application";

            this.CanHandlePowerEvent = true;
            this.CanHandleSessionChangeEvent = true;
            this.CanPauseAndContinue = true;
            this.CanShutdown = true;
            this.CanStop = true;
        }

        static void Main(string[] args)
        {
            ServiceBase.Run(new GBLibService(args));
        }
        protected override void Dispose(bool disposing)
        {
            base.Dispose(disposing);
        }

        protected override void OnStart(string[] args)
        {
            base.OnStart(args);
            this.EventLog.WriteEntry(string.Format("OnStart"));
        }

        protected override void OnStop()
        {
            base.OnStop();
            this.EventLog.WriteEntry("OnStop");
        }

        protected override void OnPause()
        {
            base.OnPause();
            this.EventLog.WriteEntry("OnPause");
        }

        protected override void OnContinue()
        {
            base.OnContinue();
            this.EventLog.WriteEntry("OnContinue");
        }

        protected override void OnShutdown()
        {
            base.OnShutdown();
            this.EventLog.WriteEntry("OnShutdown");
        }

        protected override void OnCustomCommand(int command)
        {
            base.OnCustomCommand(command);
            this.EventLog.WriteEntry(string.Format("OnCustomCommand: Command={0}",command));
        }

        protected override bool OnPowerEvent(PowerBroadcastStatus powerStatus)
        {
            this.EventLog.WriteEntry(string.Format("OnPowerEvent: powerStatus={0}", powerStatus));
            return base.OnPowerEvent(powerStatus);
        }
    }
}

4. Create ServiceInstaller Class

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ComponentModel;
using System.Configuration.Install;
using System.ServiceProcess;

namespace ServiceApp
{
    [RunInstaller(true)]
    public class MyServiceInstaller : Installer
    {
        public MyServiceInstaller ()
        {
            ServiceProcessInstaller serviceProcessInstaller = new ServiceProcessInstaller();
            ServiceInstaller serviceInstaller = new ServiceInstaller();

            serviceProcessInstaller.Account = ServiceAccount.LocalSystem;
            serviceProcessInstaller.Username = null;
            serviceProcessInstaller.Password = null;

            serviceInstaller.ServiceName = "MyService.Application";
            serviceInstaller.DisplayName = "Server Windows Service";
            serviceInstaller.Description = "Server Windows Service";
            serviceInstaller.StartType = ServiceStartMode.Automatic;

            this.Installers.Add(serviceProcessInstaller);
            this.Installers.Add(serviceInstaller);

        }
    }
}

5.Create a batch file to install/uninstall the service

@ECHO OFF
SETLOCAL
cls
echo Press Enter to Install the service
pause >NUL
echo Installing Service
sc create [ServiceName] start= auto DisplayName= "Service Display Name" binPath= "%CD%\Exefile.exe [/param /param /param...]" 
echo Done
echo Press Enter to Uninstall the service
pause >NUL
echo Uninstalling Service
sc delete [ServiceName]
echo Done
Pause
endlocal
