Windows service gives error - System.Security.SecurityException

Question

thanks for reading my post i am programming a Windows Service, and when i try to start it i get this error on the EventViewer:

Application: SerivicioBIOHAcademico.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.Security.SecurityException
Stack:

   at System.Diagnostics.EventLog.SourceExists(System.String)
   at SerivicioBIOHAcademico.BIOHAcad..ctor()
   at SerivicioBIOHAcademico.Program.Main()

Here is some code from my Service App (C#)

public partial class BIOHAcad : ServiceBase
    {
        Timer timer1 = new Timer();
        private readonly string WDcon = ConfigurationManager.ConnectionStrings["WindowsFormsApplication2.Properties.Settings.DBGriauleConnectionString"].ConnectionString;
        private readonly string UJGH = ConfigurationManager.ConnectionStrings["HorariosConnection"].ConnectionString;

        public BIOHAcad()
        {
            InitializeComponent();
            if (!System.Diagnostics.EventLog.SourceExists("Fuentes-BIO-H-Academico"))
            {
                System.Diagnostics.EventLog.CreateEventSource(
                   "Fuentes-BIO-H-Academico", "Logs-BIO-H-Academico");
            }
            eventLog1.Source = "Fuentes-BIO-H-Academico";
            eventLog1.Log = "Logs-BIO-H-Academico";
        }

        protected override void OnStart(string[] args)
        {
            try
            {
                eventLog1.WriteEntry("Iniciando Servicio BIO-H Academico");
                timer1.Elapsed += new ElapsedEventHandler(timer1_Elapsed);
                timer1.Interval = 1000;
                timer1.Enabled = true;
                timer1.Start();
            }
            catch (Exception e)
            {
                eventLog1.WriteEntry(e.ToString());
            } 
        }

        private void timer1_Elapsed(object sender, EventArgs e)

            if (conectarse == true)
            {
                DateTime corte = fecha.AddMinutes(((-1) * Holgura_Academica()));
                string dia = Funciones.ObtenerDiaSemana2(fecha);
                string hora = Funciones.ObtenerHora(fecha);
                string cortedia = Funciones.ObtenerHora(corte);
                //Llamo la conexion SQL

            }
        }
        .
        .
        .
      }

Hope you can help me to solve this, thanks in advance.

Answer 1

I fixed it, it seems the error was because i had the same logname from another service name i had, i changed it and now it seems working (let´s say it starts)

I used this from another blog to solve the error and find what was wrong

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

namespace SerivicioBIOHAcademico
{
    static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        static void Main()
        {
            try
            {
                ServiceBase[] ServicesToRun;
                ServicesToRun = new ServiceBase[] 
                { 
                    new BIOHAcad() 
                };
                ServiceBase.Run(ServicesToRun);
            }
            catch(Exception ex)
            {
                string SourceName = "WindowsService.ExceptionLog";
                if (!EventLog.SourceExists(SourceName))
                {
                    EventLog.CreateEventSource(SourceName, "Application");
                }

                EventLog eventLog = new EventLog();
                eventLog.Source = SourceName;
                string message = string.Format("Exception: {0} \n\nStack: {1}", ex.Message, ex.StackTrace);
                eventLog.WriteEntry(message, EventLogEntryType.Error);
            }
        }
    }
}

It gave me the error i needed
