Astala Vista Blogger

2006-09-25T02:46:00.000+05:30

It’s a time to say astala vista to blogger.com. I would like to thanks blogger team for such a nice tool because…

Publishing blogs with Blogger has always been like 1...2...3...
My first blog was published on Monday; October 11, 2004 on blogger.com.
I have learned to blog at blogger.

I have to think about alternative because after moving to new blogger beta, I found that, certain features which were needed and existed in the old blogger are no longer supported. Since those are necessary for me, I moved to new domain www.aamirOnline.com. My upcoming blogs will appear there. So see you at www.aamirOnline.com

Good Bye

Generics.Net

2006-08-25T11:36:00.000+05:30

With .Net 2.0 Microsoft introduced Generics; a mechanism, in .net languages
like c# and vb.net, which allows to create parameterized components (class,
function, interface, etc.). Today Generics.Net (an open source project which intend to provide templeted data structure, algorithms and other generic components, much like C++ STL library) created on CodePlex, a Microsoft's community development website. Thanks to CodePlex team. I am planning to release first pre-alpha version of Generics.Net on 10th October 2006. Till then if you have any ideas, comments, or suggestions you can share with me at Generics.Net Discussion Forum.

Understanding implicit operator overloading in C#

2006-08-15T18:03:00.000+05:30

Everyone knows that in dotnet byte, char, int, long etc are value data type and string is a reference data type. Even though being a reference type string behaves much like a value type. In other word, It can directly accepts values and doesn't require new to create an instance. For example...

string name = "M. Aamir Maniar"; //Directly accepts the value

This article explains you how to achive such kind of functionality using implicit operator overloading in C#.

Simple Encryption and Decryption with Cypher class

2006-08-03T21:01:00.000+05:30

Many times, infact i would say, in almost all our application we need to deal with data security. Whether we are dealing with querystrings, passwords, social security numbers or other secure data, we require a mechanism through which we can cipher the readable text into complex code. .Net provides many classes to achive highest levels of encryption, but how many of you are actually using them in all your application? Reason, Its complex to implement. Right?

To simplify this problem i have created a class: Cypher that help you to achive encryption and decryption in a simple manner. Following code demonstrate how to do that with Cypher class.

//To do Encryption
Cypher encryptor = new Cypher(Key);
Result = encryptor.Encrypt(MainString);

//To do Decryption
Cypher decryptor = new Cypher(Key);
Result = decryptor.Decrypt(MainString);

Encryptor is a sample application that demonstrate how to utilize Cypher class.

Documentation with .Net 2.0

2006-08-01T20:05:00.000+05:30

Becuase its ability to generate multiple kind of reference documents with a nice user friendly UI, NDoc has been a favourite documentation tool for .Net 1.0 and 1.1 applications among .Net developers. Unfortunately without being ported to .Net 2.0, NDoc project was stalled. Moreover, Visual Studio 2005, unlike earlier versions of visual studio, dosent even provide basic tool for documenting .net assemblies. This had left .net developer community hanging about creating a good documentation... To solve this state of difficulty, microsoft annonced CTP version of SandCastle, a document generating utility for .Net 2.0, which is now available for downloading from microsoft.

Please refere following links for further information...

.Net Framework 3.0

2006-07-18T22:41:00.000+05:30

July CTP of .Net version 3.0 is now available for download. What? Don't you know about .Net 3.0? Well, this is nothing but WinFx. Microsoft thought WinFx brand is not convinceing to .Net developer community, and it creates a confusion about future of .Net, so they changed the name. Version 3.0 comes with existing .Net framework 2.0 components, some additional base class library, WinFx foundation frameworks (WPF, WCF, WF and WCS) and 3rd generation .Net languages like C# 3.0 etc...

A Great Day

2006-04-04T20:19:00.000+05:30

Today established to be a great day for me. I received an award from Mr. Angelo R. Mozilo, a silver haired convinced Chairman and Founder of the Countrywide Finance Corporation, for an outstanding performance and contribution towards the organization. It was a great experience, like flying high in the sky without hot air balloons when fellow workers came forward to share good moments with me and to express greeting. Today my contribution was recognized by the organization. I received not only an award but lots of confidence in myself that I am doing best.

Making Optionals with C#

2006-03-26T00:48:00.000+05:30

As being a component or library developer one has to consider many aspects of component development. One of the such aspect is providing a feature which is not natively supported by the language in which components is being developed. For example Optional parameters feature of VB.Net. Everyone knows that optional parameters are not possible in C#. Yes, that's true, well there is a way out. Just apply OptionalAttribute defined in the System.Runtime.InteropServices to the parameter that you want to make optional. That's it, you are done...

Here is an example...

public string GetName([Optional]string param)
{
if (param == null) //Check for null.
param = "Aamir"; //Set the default value.
return param;
}

Andyes, remember C# optional parameters are not optional in C#. This is the way of creating optional parameter for vb.net.

Ways of Instantiation

2006-03-25T11:08:00.000+05:30

.Net provide many ways to instantiate an object. Here I am going to enlighten some of them.

When Type is loaded or available.
This is the most basic way of instantiating an object, To instantiate and object use new keyword, following the type’s constructor.

Object obj = new Object();

When type is not loaded or available

If you want to instantiate object dynamically when Type (class, struct, etc…) is not available or not loaded into the assembly then Activator comes at your service. You can create an instance using Activator.CreateInstance(…) and Activator.CreateInstanceFrom(…) methods. These methods provide many overloads for creating instances from various parameters. Some of examples given below.

Using Type’s object:

IObject obj = (IObject) Activator.CreateInstance( type, new object [] {"a", 10});

Here the first parameter is an object's Type, and the second parameter is an array of arguments which are supplied to the constructor of given Type.

Using Assembly and class name as string

ObjectHandle handle = Activator.CreateInstance( "AssemblyName","NamespaceName.ClassName" );
IObject obj = (IObject)handle.Unwrap();

There are other overloads also please check out MSDN document…

Back @ Blogger

2005-01-22T16:46:00.000+05:30

Hey Guys

I am back on blogger. Busy schedule at patni has kept me away from writing blogs... Even after leaving patni i could not managed to achive those enthusiasm and exitements towards the latest technologies. But these days i again exprience those same excitements. So decided to update the blog... In the coming days I will be completing Generics.Net and Software-Architect.net, my two most lovable and incomplete projects. All the best to me....

Software-Architect.net Alpha has been launched for testing...

2004-11-03T21:11:00.000+05:30

Today I am very happy because i could publish alpha version of my long awaited project www.software-architect.net . I am sure that this project will bring lots of information to the software architects... It aims to be a single stop online directory and forum for the software architects... Thought currently it is under testing, some parts still required to be developed and lots and lots of information need to be indexed... I wish that I could finish it as soon as possible so that i can make it available to public...

If your are software architect I need help, sugessions, ideas and knowledge from you to make www.software-architect.net a complete software architectural information tool....

Generics.Net

2004-10-11T17:34:00.000+05:30

I was very amazed by the new C# feature Generics.... When i heard about generic & its similarity with templates of c++ i started thinking about a library similar to STL (Standard Template Library). All those thought resulted into project called Generics.Net.

Generics.Net is a class library, which aims to provide collection of template algorithms & data structures. Currently this library in its planning stage...

So if you are interested in contributing Generics.Net please point your browser towards http://workspaces.gotdotnet.com/generics, a project workspace provided by GotDotNet.
