var Vs dynamic - Difference [C#] [ASP.NET]

2014-04-09T00:24:00.001-07:00

Here's an important interview question asked mostly in interviews of top companies like TCS, Infosys, Capgemini, Cognizant, JP Morgan, Nomura, etc

var	dynamic
Introduced in C# 3.0	Introduced in C# 4.0
Statically typed – This means the type of variable declared is decided by the compiler at compile time.	Dynamically typed - This means the type of variable declared is decided by the compiler at runtime time.
Need to initialize at the time of declaration. e.g., `var str=”I am a string”;` Looking at the value assigned to the variable `str`, the compiler will treat the variable `str` as string.	No need to initialize at the time of declaration. e.g., `dynamic str;` `str=”I am a string”;` //Works fine and compiles `str=2;` //Works fine and compiles
Errors are caught at compile time. Since the compiler knows about the type and the methods and properties of the type at the compile time itself	Errors are caught at runtime Since the compiler comes to about the type and the methods and properties of the type at the run time.
Visual Studio shows intellisense since the type of variable assigned is known to compiler.	Intellisense is not available since the type and its related methods and properties can be known at run time only
e.g., `var obj1;` will throw a compile error since the variable is not initialized. The compiler needs that this variable should be initialized so that it can infer a type from the value.	e.g., `dynamic obj1;` will compile;
e.g. `var obj1=1;` will compile `var obj1=” I am a string”;` will throw error since the compiler has already decided that the type of obj1 is System.Int32 when the value 1 was assigned to it. Now assigning a string value to it violates the type safety.	e.g. `dynamic obj1=1;` will compile and run `dynamic obj1=” I am a string”;` will compile and run since the compiler creates the type for obj1 as System.Int32 and then recreates the type as string when the value “I am a string” was assigned to it. This code will work fine.

Travel Without Printout of E-Tickets

Travel Without Printout of E-Tickets - Travel with Electronic Tickets

Good News for all train passengers

An Appeal to passengers

Carry your tickets in electronic mode on
-Laptop
-Mobile
-IpadEnvironment Friendly

Must carry a valid ID

Save Paper

We can almost save 3 lakh A4 size paper every day.

This is a great initiative by the Indian Railways to allow the passengers to not carry the e-ticket & simply take a screen-shot of the e-ticket & display it through laptops/palmtops/ Mobile phone which will be referred as Virtual Reservation Message (VRM).

As we all know about the Electronic Reservation Slip (ERS) - The printout in standard specified Performa containing reservation particulars, and instructions for use which can be used by the passenger along with the relevant authorizedIdentification, as travel authority for performing the journey.

So from onwards if you are traveling by train, then ERS/VRM along with any one of the eight prescribed ID proofs in original and the indication of the passenger(s)' name(s) in the Reservation Chart will authorize the passenger to travel.

VRM combined with valid photo-id in original will be treated as an instrument on par with the ERS.

ERS/VRM along with one of the eight prescribed proofs of identity in original will also authorize the passenger to enter the platform on the day of journey and he/she will not be required to purchase platform ticket. ERS/VRM along with original id proof will be required to be produced on demand of Ticket Checking Staff on the platform.

Hope this information will be helpful.

What's New in .NET 4.5

What's New in .NET 4.5

Body onload function in content page in asp.net

2011-09-15T01:17:00.000-07:00

Body onload function in content page in asp.net

While working on one of the application, I had a master page & on one of the content page's body onload, I had to run a JS function.

To do this first you need to add an ID & runat attribute to the master page's body control. Like this:

In master page:

--code <body id="body" runat="server"> </body>

Now in content page, in the page load event, add this code:

protected void Page_Load(object sender, EventArgs e)
{
HtmlGenericControl body = this.Master.FindControl("body") as HtmlGenericControl;
body.Attributes.Add("onLoad", "alert('Hello World');");
}

I hope this simple tip will be helpful...

NET framework 2.0:

It brings a lot of evolution in class of the framework and refactor control including the support of

Generics
Anonymous methods
Partial class
Nullable type
The new API gives a fine grain control on the behavior of the runtime with regards to multithreading, memory allocation, assembly loading and more
Full 64-bit support for both the x64 and the IA64 hardware platforms
New personalization features for ASP.NET, such as support for themes, skins and webparts.
.NET Micro Framework

.NET framework 3.0:

Also called WinFX,includes a new set of managed code APIs that are an integral part of Windows Vista and Windows Server 2008 operating systems and provides

Windows Communication Foundation (WCF), formerly called Indigo; a service-oriented messaging system which allows programs to interoperate locally or remotely similar to web services.
Windows Presentation Foundation (WPF), formerly called Avalon; a new user interface subsystem and API based on XML and vector graphics, which uses 3D computer graphics hardware and Direct3D technologies.
Windows Workflow Foundation (WF) allows for building of task automation and integrated transactions using workflows.
Windows CardSpace, formerly called InfoCard; a software component which securely stores a person's digital identities and provides a unified interface for choosing the identity for a particular transaction, such as logging in to a website

.NET framework 3.5:

It implement Linq evolution in language. So we have the folowing evolution in class:

Linq for SQL, XML, Dataset, Object
Addin system
p2p base class
Active directory
ASP.NET Ajax
