I've been asking a question about this key word on every interview. Most of them think that this is used only to reference the base class, apart of that, there is also a great usage with this key word. This key word, USING, can be used to destroy the objects (automatically) when they are no longer required in the memory. At times, the developer will forget to write the code to destroy the created objects. These objects pile up on system memory and wait for the GC to collect and clean them. How it would be if they are cleanned as soon they finish their requirement? That would be great coding and you are reducing the work for GC during the collection process. Here is how to accomplish the same. First, implement the IDisposable interface on the object that you are planning to implement automatic collection and allow CLR to release the allocated memory as soon this object is no longer required. class SmpCls: IDisposable { void IDisposable.Dispose() { Console.WriteLine("Disposing t

I've been trying to chakout the ACID , from quite a long time.. and postponing the same, every time i think of it... today, i decided to draft what i mean for ACID As every one know, ACID means A tomicity C onsistent I solated D urability This is common from high level understanding, what about in detail? In this post, i'm trying to post all my understanding about these 4 buzz words, correct me if i'm mistaken (or) miss spelled Atomicity : this is in general talks about the changes or activities that are supposed to be happen in the given transaction. Inother words, all the changes that influence on the resource must happen on a single process or thread or operation , means on any kind of exception, the enitre thread has to be aborted. I recollect some statement from some of MSDN Magazine, " Every thing in the universe stops, the changes are made, and then every thing resumes " Consistent : means the transaction should be on a crystal clear state of Yes or No, in

We all know that an object is the instatnce of any given class, are we really sure that every class code can be instantiated as Object ?!#$%^* Is there any thing that is hidden behind the screen of "CLASS". Is any piece of code that is embedded with in "{" and "}" can be considered as "Class"? During my study with W3C.com, i come to a conclusion that, the following features are must for any piece of code to be instantiate as an object. 0) Type 1) Only one Distructor allowed per class 2) Indexer facility should be provided 3) Default Constructor 4) Parameterised Constructor 5) Constant 6) Fields 7) Properties 8) Methods 9) Events If any given code / class that supports all these features, that can be considered for instantiating as an Object. What do you say ?

Now-a-days i'm writing SQL Server Triggers and StoredProcedures while working with the current project. During the process of recollecting my database knowledge, it took me a little time but finally with much difficulty completed the first task. My past experience handling Database is with Oracle 7x/8.1.5 and 8.1.6, while developing the triggers / cursors / stored procedures / for that matter on every moment i recollect the Oracle Syntax and get confuse with the SQL Server Syntax. Just as an example, Oracle Supports SEQUENCE where as SQL SERVER supports the same facility as IDENTITY column as auto number. Similar such, many-a-things, but thank god for giving me a great ability to learn technology with a great pace. During this process i visited sqlteam.com sqlknowledge.com devarticles.com/c/b/sql-server/ extremeexperts.com sqlteam.com sqlservercentral.com Did you visit these?

What's WiMo ... ?!@#$% ^&* WiMo is the the Windows Mobile Robot.

It is really quite long time to post the new happenings in my life and learning ... As the title says, I’m currently working with XYKA as Project Lead. The interesting part working here is the current project. Xyka owns a travel product and is now integrating with different partners across the globe towards reservation related issues. My interest is not to disclose the internals of the product, but to throw light on what I’m working. The UI of this product is common for different partners that are integrated with this product. As the UI is in-place working fine and with out errors, now it is the time to develop an interface to integrate the same UI with one of their other partner. The partner results data in XML Format and this product expects data in a Class objects. Now it is my turn to work on XML DataIlands to convert these pieces of data from the partner WebXMLInterface to the product’s class objects. A picture is worth of 1000 words, here comes the picture.. The partner system e

This article throws light on all the ways that you can check for the performance for the application designed using .NET.   Most of them, though exists prior to .NET, but I guess people are not given importance to them.
