Validation to Check for Comma separated EmailIDs

Regular Exp Description:

List of Email ids separated with [,] Email ID may contain character set as [._-']

Regular Expression

^((\w+([-_.']\w+)*@\w+([-_.']\w+)*\.\w+([-_.']\w+)*)*([,])*)*$

Regular expression Rules:

Finite automata rule Values should proceed with email Ids with Comma Separated. No comma will precede the email IDs.

Matches:

abc.xyz@anonymous.com
abc.xyz@anonymous.com,abc-xyz@anonymous.com,abc_xyz@anonymous.com
abc.xyz@anonymous.com,com,D'Souza@anonymous.com

Non-Matches:

abc.xyz
,abc.xyz@anonymous.com
abc.xyz@anonymous.com,
abc

Javascript
function CheckForCommaSeperatedEmailIDs( fieldValue )  
       {      
     
         var regex = /^((\w+([-_.']\w+)*@\w+([-_.]\w+)*\.\w+([-_.]\w+)*)*([,])*)*$/;      
         if( !fieldValue.match( regex ) )      
           {         
             alert('The Email IDs Invalid');
            
                     return false;      
                       
            }     
               return true; 
         }



Validation to check UserID with Period/Dot seperated

Regular Expression Rules:

Finite automata rule, Values should precede with characters of set [A-Za-z] and followed with period(.) and character set [A-Za-z]

Regular Expression:

^[a-zA-Z]+(\.[a-zA-Z]+)+$

Matches

1) Ratan.Tata
2) Anil.Dhiru.Ambhani

Non-Matches

Ratan.
1) .Mukesh.
2) Amir.khan.

Regular Expression Logic in Javasctipt

function CheckForPeriodSeperatedUserID( fieldValue ) { var regex = /^[a-zA-Z]+(\.[a-zA-Z]+)+$/; if( !fieldValue.match( regex ) ) { alert('The UserID is not desired format,XXX.YYYY XXX.YYYY.ZZZZ'); return false; } return true; }

Real Time Use Of Static Constructor if you look at above class it is an Utility class and it is consume by Business entity class instance say object Date that has minute component in it. If we have 10 screens that requires minutes to be displayed in dropdownlist in such cases rather then calling 10 calls to database or constructing this collection we prefer calling one instance at the very load of the application which in turns consume by all the pages and across all the users. In the process we have one instance available for all users and across pages. If one see in normal constructor ,one can notice it is invoked after instance is created whereas static constructor is invoked always first and when it is referenced. use System.collection.generics; public class Utility { public static IDictionary m_Minute = null; static Utility() { m_Minute=new IDictionary(); m_Minute.Add(1,"00"); m_Minute.Add(2,"15"); m_Minute.Add(3,"30"); m_Minute.Add(3,"45"); } public static IDictionary GetMinute() { return m_Minute; } } Validation to Check for special Character Description : Below javascript code function returns false for entered special character and true for non special character. function CheckForSpecialCharacter( controlValue ) { var regex = /^[a-zA-Z0-9\s]+$/; if( !controlValue.match( regex ) ) { alert('Special Character is not allowed due potential security threat.'); return false; } Problem Statement: We have scenario where we have data stored in arraylist collection and want to pass this as data as input to Webservice method in string array format. Convert ArrayList() Collection to String [] Array Namespace: System.collections Solution: private string[] ConvertArrayListToStringArray(ArrayList arrList) { for (int iIter=0;iIter<5 br="" iiter=""> { arrList.Add("StringValue"+iIter); } return string[]arrList.ToArray(typeof(string)); }   Iterator,Delegate,Predicates,Anonymous method and Generics C#2.0 A perfect blend of Iterator,Delegate,Predicates,Anonymous method and Generics C#2.0. One can make use of these in real world scenario to save memory and increase performance of an application. Delegates defines signature of any method that takes one input parameter and returns a single object of another type. public delegate Tout Action(Tin element); protected void Page_Load(object sender, EventArgs e) { foreach (string str in GetFormatedCustomerName()) Response.Write(str); } public IEnumerable GetFormatedCustomerName() { List customerList=new List(); customerList.Add(new Customer("001", "Santosh",3552)); customerList.Add(new Customer("002", "Poojari", 42424)); customerList.Add(new Customer("005", "Arjun", 42424)); return BuildFormattedName(customerList, delegate(Customer objCustomer) { return string.Format("{0} - {1} ", objCustomer.CustomerId, objCustomer.CustomerName); }); } public IEnumerable BuildFormattedName(IEnumerable list, Action handler) { foreach (Tin entry in list) yield return handler(entry); }

Javascript Basics Tutorial Part 6 : Nested Function

Nested Function---> Outer Inner function.

Semantics
function Outer(n)
{
      function Inner()
      {
          do something with (n);
          return n;
      }
      return Inner// Call Inner function;

Javascript Basics Tutprial Part 5: Self Calling Or Immediate function.

Lets look at syntax representation of Self calling or Immediate function call.

Method 1
(
        function ()
       {
             something;
       }
)
( ) ;//This is self fn call

Method 2

(
      function ()
     {
          something;
      }

      ( )
) ;

Method 3
(
function  Anything()
{
something;
}

( )
) ;

The only difference is ( ) is inside or outside in the example above.

Javascript Basics Tutorial : Part 4 Var obj={};

Part 4 : var obj={};
Remember this semantics var X= {};

This chapter we will discuss how we can defined multiple methods and variable in OBJECT. The sample code describes the methods scope within OBJECTS and its declaration and semantics.
Understand diff between semantics and Syntax.

Key notes here direct call to f1(), f2() and f() are INVALID. This is concepts of data encapsulation. Its implementations are hidden to outer world. Like we know how to drive car without knowing how it is internally deviced and operated.

Javascript Basics Tutorial Part 3: Anonymous Methods

Anonymous Method Like C#.
Important Key notes:

1. All Methods are funtions but funtions are not method.
2. Methods can not be called before it is being defined. Unlike FUNCTIONS.
3. Methods is represented as variable and function is assigned to it.
4. Methods is variable and any var declaration must ends with semicolon.
5. Methods can be declared as Anonymous with no name and can be declared with Named Expression.

var obj= function(){somthing;} ;

Javascript Basics Tutorial Part 2: Simple Function.

:In part 2 we are going to look into details of simple function declaration and its defination. We also look into function scope. Refer Part 1 for Objects and Array.

Function Scoping: Function can be called before it is defined. Look at below example.

Function : By default every function is like default constructor with inbuilt arguments.
We can also put debugger; to put a breakpoint and debug to step-in, step-out, step-over in vs 2010.

In short we can defined function with NO Input Argument but we can pass multiple input parameter values of any type while calling a function.
 
f2(17, 0.1, "Ninja", [], {});

function f2()
{
//Fn Responsibilty & Operations.
}
Interesting facts: Inside a function we can fetch the inputs values to the function through a array called arguments[].Internally it is stored in arguments[] array placeholder where we can reference and use the input values for the operations.

Javascript Basic Tutorial Part 1:Objects & Array

Here is the quick series of javascript begineer kit.
To make learning easy, below are the code demos with screenshot.
So lets get started

Objects & Array

All I have done is taken one default.aspx with all javascript references and one div tag to display results. We also have JQuery online reference just to have ready() function and few Jquery selector to create showresults() display panel.

Common Utility.JS

In order to simplify this kits, I have replaced alerts with ShowResults code snippet. There is a global array and global Method to display outputs. I'll be using ShowResults() Method to display output for each javascript demo.

Chapter 1. Objects & Array

1. var obj={} represents objects
2. var arr=[] represents array

The skeleton to define object are as given below. There are two ways to do it.

var dog={};

dog.breed='abc';

dog.bark= function(){

//some operations;

}

This defination involves comma separated property and method. The important note here is dog object is notated as a var defined as class with property and method. Always remember closure always ends with semicolon as it is assigned to var . Like

var animal= { something;};

var dog ={
breed:'abc', bark=function(){
}

}
};

Output

Object Oriented, functional and closure view of Jquery

Jquery =$

Well, I have been too much into Jquery. Being C# developer by nature its always been hard to adopt the style of programming in Jquery. What differentiate more is the style and modularization we have in C#. Apparently I like Jquery and try to code it as modular as I can.

Here is quick reference of MSDN magazine issue, Script Junkies....
http://msdn.microsoft.com/en-us/magazine/gg476048.aspx

Here you will understand following few important things.

1.  Functional way of programming Jquery
2.  Jquery Plugins
3.  Objects in Jquery
4.  Object-orientation through Closures
5.  Object-orientation through Prototypes
6.  Inheritance In Jquery

Functional Jquery:

1. // Function to calculate a total
2. var CalcTotal = function(x, y) {
3. return x + y;
4. };
6. // Function to add taxes
7. var AddTaxes = function(x) {
8. return x * 1.2;
9. };
11. // Function that pipelines the other two
12. var CalcTotalPlusTaxes = function (fnCalcTotal, fnAddTaxes, x, y) {
13. return fnAddTaxes(fnCalcTotal(x, y));
14. };
16. // Execution
17. var result = CalcTotalPlusTaxes(CalcTotal, AddTaxes, 40, 60);
18. alert(result);

How to write Jquery plugins

1. jQuery.fn = jQuery.prototype = {
2. init: function( selector, context ) { ... },
3. size: function() { return this.length; },
4. each: function( callback, args ) {
5. return jQuery.each( this, callback, args ); },
6. ready: function( fn ) { ... }
7. :
8. }

Objects in Jquery

1. var person = new Object();
2. person.Name = "Dino";
3. person.LastName = "Esposito";
4. person.BirthDate = new Date(1979,10,17)
5. person.getAge = function() {
6. var today = new Date();
7. var thisDay = today.getDate();
8. var thisMonth = today.getMonth();
9. var thisYear = today.getFullYear();
10. var age = thisYear-this.BirthDate.getFullYear()-1;
11. if (thisMonth > this.BirthDate.getMonth())
12. age = age +1;
13. else
14. if (thisMonth == this.BirthDate.getMonth() &&
15. thisDay >= this.BirthDate.getDate())
16. age = age +1;
17. return age;
18. }

Object-orientation through Closures

1. var Person = function(name, lastname, birthdate)
2. {
3. this.Name = name;
4. this.LastName = lastname;
5. this.BirthDate = birthdate;
7. this.getAge = function() {
8. var today = new Date();
9. var thisDay = today.getDate();
10. var thisMonth = today.getMonth();
11. var thisYear = today.getFullYear();
12. var age = thisYear-this.BirthDate.getFullYear()-1;
13. if (thisMonth > this.BirthDate.getMonth())
14. age = age +1;
15. else
16. if (thisMonth == this.BirthDate.getMonth() &&
17. thisDay >= this.BirthDate.getDate())
18. age = age +1;
19. return age;
20. }
21. }

Object-orientation through Prototypes

1. // Pseudo constructor
2. var Person = function(name, lastname, birthdate)
3. {
4. this.initialize(name, lastname, birthdate);
5. }
7. // Members
8. Person.prototype.initialize(name, lastname, birthdate)
9. {
10. this.Name = name;
11. this.LastName = lastname;
12. this.BirthDate = birthdate;
13. }
14. Person.prototype.getAge = function()
15. {
16. var today = new Date();
17. var thisDay = today.getDate();
18. var thisMonth = today.getMonth();
19. var thisYear = today.getFullYear();
20. var age = thisYear-this.BirthDate.getFullYear()-1;
21. if (thisMonth > this.BirthDate.getMonth())
22. age = age +1;
23. else
24. if (thisMonth == this.BirthDate.getMonth() &&
25. thisDay >= this.BirthDate.getDate())
26. age = age +1;
27. return age;
28. }

Inheritance In Jquery
By using the prototype feature you can achieve inheritance by simply setting the prototype of a derived object to an instance of the “parent” object.

Developer = function Developer(name, lastname, birthdate) 
{ 
   this.initialize(name, lastname, birthdate);
}
Developer.prototype = new Person();

Beginner MVC4 Web API : Learning 1

It’s been long time since I have not been writing much here. Finally I got time to write something on technology. I installed VS2012 professional and I took a first look of MVC4 framework web API. I don’t know how much application architect will see this framework to work as per business need. It depends upon the requirement in all aspects such performance, scalability, usability, availability, maintainability etc. All these factors play a crucial role in deciding the adoption of any architectural model or framework. Same goes with data architect and so on. Well my take is always a model view presenter as I’ve been developing all my application from my career start in MVP. Now it’s time to change and change is always good. Everyone wants you to know and use MVC.

I followed the tutorial online which helped me understand the basic.

Why MVC?

·         Clean URL

·         Loosely Coupled-Separation of concerns

·         Restful Service

·         Make use of Web API.Json, Jquery and Javascript and lot

·         Mobile platform

·         Best for Unit testing

·         Flexible GUI/UI design.

·         Efficient Search engine Optimization

Some known characters in MVC framework..I will not spend time talking much about the underlined definitions of MVC and all . I would rather like one to know few important key things that are must.

1)      MVC 4 framework development using Razor and Scalfold templates.

2)      MVC4 Web API using JQuery, Json and JavaScript.

3)      MVC4 Filters, Routing, bundles and Web API configuration.

If one tries to understand above construct in much better form then it’s much easier to grasp the overall learning of MVC 4 framework. Thanks GOD I started now as many revolutionary changes have been done from MVC1 to MVC4. Hopefully I neither want to go in past nor want to understand the flaws or round way of doing things.

Recommendation is to try below references to self start.

Performance Unrivaled: Quick heal solution to asp.net website performance

For me the performance of any web application can be assessed by only two important factors. One is processing of code in server and then carrying those processed output though network & wires to end users. If you processed your code faster than output transmittal through wire is another parameter that makes lot of difference. Its thumb rule, less weight faster it traverse through wire and get downloaded at browser much less time. My intention is to bring some light on these two things. There are different aspects of scale out and scale in approach to support huge user base but that is not my objective. My first level to assess any application is to probe these areas, what time it takes for any code to get processed and give output and next more interesting; how fast I can pass that output to end users browsers window?

1) Time to process input and give output
2) Time to transmit the processed output to end users

This is first level approach to improve performance of any system according to me. Then what comes next is, system capacity thereafter all planning to scale in or scale out servers to support concurrent/user base count. Not to waste much time out here understanding those nitty-gritty’s. My focus areas are,
Part 1
1) Code review. Reduce Warnings. Apply best practices Common e.g make use of string.builder , string.empty, string.IsnullOrEmpty()==true, Remove unwanted references.
2) Check cyclomatic complexity. Terminate unnecessary looping ,apply break if possible
3) Always keep tracing and bebug false
4) Use Server.transfert wherever possible
5) Make use of datareader wherever possible. Reduce use of dataset
6) Open and close the connection in the method.
7) Explicitly close connections in case of data reader.
8) When using DataReaders, specify CommandBehavior.CloseConnection.
9) Do not explicitly open a connection if you use Fill(SQL dataadapter or Update for a single operation.
10) Avoid checking the State property of OleDbConnection.
11) Connection Pooling.

http://msdn.microsoft.com/en-us/library/ff647768.aspx
12) Check for number of tier database calls. Say for example –if one page makes 20 database calls then this is of concerns. Reduce number of database call. Keep tier less chatty. Identify this bottleneck using VS2010 Tool.http://blogs.msdn.com/b/habibh/archive/2009/06/30/walkthrough-using-the-tier-interaction-profiler-in-visual-studio-team-system-2010.aspx

Part 2
1) Reduce Viewstate size. Tool Enable page trace=true at page level
2) Use JQuery +Jason for low weight data display. Popup etc.
3) Ajax
4) http://msdn.microsoft.com/en-us/library/ff647768.aspx
5) Remove Favicon.ico if not required .Use http://haacked.com/archive/2008/07/14/make-routing-ignore-requests-for-a-file-extension.aspx

Reduce javascript file size .use Minify JS tool
Reduce CSS fie size .Use Minify CSS tool
Smush and optimizes image. Use All Smush.it tool. Check this out http://www.smushit.com/ysmush.it/

. Select file such image folder , css and javascript..
2.Click the HTTP Headers tab.
Select the Enable content expiration check box.
Click Expire immediately, Expire after, or Expire on, and type the appropriate expiration information in the corresponding boxes.Click OK.

IIS 7.5 Architecture Insights

Recently I started migration of applications from win 2003 OS platform to Win 2008. With this I decided to move to .net 4.0 and of course the IIS 7.5 What really surprise me the changes that has evolved in these technology, platform and environment in totally. The IIS and .net has matured lot and becoming stronger in each version releases Microsoft does.

IIS 6.0 vs 7.5 Architecture Insight
IIS6.0 -Web service Extension:We used to have web Server Extension. In IIS 6.0 is enabled only to support client static content and in order to enabled server side aspx, asp,.asmx, .svc, webdav, front page server extensions etc we have to make use of Web server Extension options in IIS( Inetmgr).
ALLOW and Prohibit Options Available.

IIS 7.5 -ISAPI & CGI this is exist in server extension in win server 2008 R2 or in Program On and Off feature in Control Panel. Once they are enabled it is available in IIS root.

IIS7.5 Integrated & Classic (6.0) mode of operatability.

IIS6.0- IIS and ASP.net has its own authorization/authentication model.
IIS7.5 Integrated Mode combines IIS & ASP.net Authentication/Authorization
IIS 6.0 Architecture
Architecture
Lsass.exe: Security and SSL
Inetinfo.exe: hosts the non-HTTP services and the IIS Admin Service, including the Metabase.E.g SMTP, FTP
SvcHost.exe: host operating system services; in the case of IIS, it hosts the Web (HTTP) service. www services, asmx, WAS – Window activation services for WCF binding –TCP and MSMQ

It has W3SVC.exe is user mode component that bridge communication between user mode and kernel mode. http listener handles request for kernel http stack through http.sys protocol stack
W3wp.exe: multiple W3wp.exe processes, one for each application pool.
ASPnet_ISAPI.dll
ISAPI Filter
ISAPI Extension
APP Domain
In Web-garden one application is divided into separate processes, -multiple instances of the same worker process.

IIS 7.5 Architecture
Additional Listener Adapter
Listener Adapter
World Wide Web Publishing Service (hosting the listener adapter)
NET.TCP listener adapter
NET.PIPE listener adapter
NET.MSMQ listener adapter

Protocol-specific listener adapters support all four WCF transports, instead of only HTTP in IIS 6.0. In addition, a new operating system service is available called Windows Activation Services (WAS). Both W3svc.exe and WAS are running inside an operating system host called SvcHost.exe
WAS is the new process activation service that is a generalization of Internet Information Services (IIS) features that work with non-HTTP transport protocols. WCF uses the listener adapter interface to communicate activation requests that are received over the non-HTTP protocols supported by WCF, such as TCP, named pipes, and Message Queuing.
WAS activation is not supported if the web server’s request processing pipeline is set to Classic mode. The web server’s request processing pipeline must be set to Integrated mode if WAS activation is to be used.
