How to create Custom Installers?

Hi,

This video tutorial will show you how to create custom installers. This example uses topic from Logging Application State, if you haven't seen its example.Check out the below link:

Logging and System Management

I have divided the tutorial in two part. The links are below:
1. How to create Custom Installers Part 1
2. How to create Custom Installers Part 2

How to create Custom Installers Part 2

Code for MyInstaller.cs class is as given below :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Configuration.Install;
using System.ComponentModel;
using System.Collections;
using System.Diagnostics;

namespace SimpleApplication
{
    [RunInstaller(true)]
    public class MyInstallerClass : Installer
    {

        public MyInstallerClass()
            : base()
        { }

        public override void Commit(IDictionary savedState)
        {
            base.Commit(savedState);
        }

        public override void Install(IDictionary stateSaver)
        {
            base.Install(stateSaver);
            CreateEventLog();
        }
        public override void Rollback(IDictionary savedState)
        {
            base.Rollback(savedState);
            DeleteEventLog();
        }
        public override void Uninstall(IDictionary savedState)
        {
            base.Uninstall(savedState);
            DeleteEventLog();
        }

        public void CreateEventLog()
        {
            if (!EventLog.Exists("SimpleApplication Log"))
            {
                EventLog.CreateEventSource("SimpleApplication", "SimpleApplication Log");
            }
        }

        public void DeleteEventLog()
        {
            if (EventLog.Exists("SimpleApplication Log"))
            {
                EventLog.DeleteEventSource("SimpleApplication");
                EventLog.Delete("SimpleApplication Log");
               
            }
        }
    }
}

Code for program.cs is as given below :

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

namespace SimpleApplication
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("This is my simple application");
            Console.ReadKey();
        }
    }
}

}

EventLog mylog = new EventLog("My Log");
mylog.Source = "Sam Application";
mylog.WriteEntry("Could not connect", EventLogEntryType.Error, 1001, 1);

Console.WriteLine("Event log written now trying to read from event log");
Console.ReadKey();
Console.Clear();
foreach (EventLogEntry entry in mylog.Entries)
Console.WriteLine(entry.Message);
Console.WriteLine("Press any key to exit!!!");
Console.ReadKey();

}
}

How to use back references to match the patterns?

Hi,
I have provided a sample example of how to retrieve matched data from a text file using backreferences. This tutorial will help us in understanding how to create a regular expression for matching the repeating patterns from a source.I will explain in the video tutorial about how to match repeating letters and how to match repeating words from a given source. We will also see how to construct a regular expression for the above scenarios.After we do that we will see how to extract matched data from the source and use it for our purpose.
