Build your own Forms Authentication

The authentication ticked is created with the FormsAuthenticationTicket class. Its constructor accepts the following parameters:

version : The version of the authentication ticket[this value will be one]
name : The user name associated with the authentication ticket
issueDate : The date that the authentication ticket was issued
expiration : The date that the authentication ticket should expire
isPersistent: A boolean value indicating whether to allow the ticket to persist
after the user closes the browser
userData : A string value of any data that you would like to store. For eg.,
say your email ID.

Add an asp.net form, with a button 'Create Ticket'. On click on this button invoke the 'Login' method.

void Login(Object s, EventArgs e)
{
if (txtUsername.Text == "xxx" && txtPassword.Text == "xxx")
{
FormsAuthenticationTicket objTicket;
HttpCookie objCookie;
objTicket = new FormsAuthenticationTicket(1, txtUsername.Text,
DateTime.Now, DateTime.Now.AddMinutes(60), true,
"tt@server.com");
objCookie = new HttpCookie(".ASPXAUTH");
objCookie.Value = FormsAuthentication.Encrypt(objTicket);
Response.Cookies.Add(objCookie);

Response.Redirect("Default.aspx");
}
}

In the default.aspx Page_Load event add the following code..

void Page_Load() {
FormsIdentity objTicket;

objTicket = (FormsIdentity)User.Identity;
lblName.Text = objTicket.Ticket.Name;
lblIssueDate.Text = objTicket.Ticket.IssueDate.ToString();
lblExpiration.Text = objTicket.Ticket.Expiration.ToString();
lblIsPersistent.Text = objTicket.Ticket.IsPersistent.ToString();
lblVersion.Text = objTicket.Ticket.Version.ToString();
lblUserData.Text = objTicket.Ticket.UserData;
}

Enjoy coding..

JavaScript Scope

In this blog post we will dig deeper into various aspects of JavaScript scope.  This is a pretty interesting topic  and also a topic which confuses many beginning JavaScript programmers. Understanding JavaScript scope helps you write bug free programs (hmm.. atleast helps your troubleshoot things easily) Scope control the visibility and lifetimes of variables and parameters.  This is important from the perspective of avoiding naming collisions and provides memory management service. Unlike other languages, JavaScript does not have block level scope.  For e.g. take for instance the following piece of c# code. public void Main () { int a = 5; if (true) { int b = 10; } // This will throw compile time error as b is not defined // and not within the scope of function Main(); Console.WriteLine(b); } If you write the same code in JavaScript, then the value of 'b' will be available outside the 'if' block. The reason for this is JavaScript does no

These are just my thoughts, but some you may find something interesting in it. Please think over it. We may know many things, but still we always keeps procrastinating it.

JavaScript for Web and Library Developers

This is my first blog post on my home domain and in this series of posts I will explore various facets of JavaScript language that will help us become better programmers.  The idea is tear apart the language and understand how to use the features and build libraries like jquery, knockoutjs, backbonejs. The idea is not to replicate this libraries, but understand the inner workings using better JavaScript coding practices, design principles and thereby make the web a better place to visit.. We will be covering the following topics, though not in order and there may be addition to this list. Foundations Patterns Closure this keyword Hoisting Anonymous function Currying Server side JavaScript Canvas etc. Hope you will enjoy this journey with me!
