Dataset JSON Serialization

There definitely seems to be some problem serializing dataset in the latest 'RELEASE' version of ASP.NET

It keeps on giving some 'Circular Reference Error' while deserializing a ASP.NET dataset.

After lot of researching on the web , this is how I solved it

1. Downloaded ASP.NET ATLAS JAN CTP from here:

2. Added reference to Microsoft.Web.Preview.dll

3.Added following lines to web.config

<add name="DataSetConverter" type="Microsoft.Web.Preview.Script.Serialization.Converters.DataSetConverter, Microsoft.Web.Preview"/>
<add name="DataRowConverter" type="Microsoft.Web.Preview.Script.Serialization.Converters.DataRowConverter, Microsoft.Web.Preview"/>
<add name="DataTableConverter" type="Microsoft.Web.Preview.Script.Serialization.Converters.DataTableConverter, Microsoft.Web.Preview"/>

4. My web service returns a typed dataset with ID and Name columns.

Now these javascript lines work:

Planning to write a game!

Couldn’t think of better way of learning a new language. I am seriously thinking of writing a game using Ruby and SDL. I know ruby is not the best language to do this, but
I just want to get exposed to the field.

Here is the list of things I need to learn for making my first game:

1] SDL (Simple Device Layer)
2] Sprites (I find the concept very interesting)
3] Collision detection (I guess will be complex)
4] Free music and sounds (Yes! They are very important)
5] Game loop (Is that what is it called?)

Right now I am desperate to find more information on above stuff. My first game would be very simple, maybe car racing or shooting.

Hmmmm ....some real interesting time ahead.
My 'First Game'!!

AJAX Bar Graph with ASP.NET

Just posted script, demos and article for creating AJAX Bar Graph with ASP.NET(2.0). Using my script you can create AJAX Bar Graphs using only HTML and ASP.NET. They can be used to show real time information like cricket scores, stock quotes, temperature or any numeric data streaming form a web server.

Download the code and run it from your local machine. Here is the link

I am also working on page that demonstrates how to use the script with any server side programing language. Once it is ready , you will find it on my website !

Started Learning Ruby!

'But why?' Is the first question people ask.

I heard of Ruby long ago. That time I only knew that it was invented and pretty popular in Japan. But then came ‘Ruby On Rails’. Being a web developer, I couldn’t overlook its popularity.

So one fine day, I decided to try ‘Rails’ myself. But I soon realized, I needed to learn ‘Ruby’ first. Seemed logical. (You need to learn C++, before you can do anything with MFC).

So, I am learning Ruby. I would have preferred learning Python, but I found learning Ruby (and Ruby on Rails) could be more beneficial to my professional. That doesn’t mean I am giving up ASP.NET.

This is a common problem, which I see with people. When they see someone learning something not ‘directly’ related to his/her work, they think he/she is looking for a switch. Many of us (at least here in India) grow up learning ‘C’ like languages. Our (including myself) conception of a programming language is something very close to ‘C’. This is the reason I am very comfortable with languages like C\C++\Java\C#\Javascript etc. Anything different becomes hard to digest as a programming language. It is in no way a reason to worry because I can solve the problem which I am supposed to!

This is not a question of ‘my language is better than yours’. Learning new languages teaches valuable lessons on programming style, concepts and elegance. Performance and utility are entirely different topics. Every language has its strong points and ways of writing elegant code. There can be no single language that can have all the best features.

I am reading the book ‘Programming Ruby’ by Dave Thomas and Andy Hunt, and believe me just skimming thorough the book has exposed me to scores of different programming concepts, constructs and strategies. Imagine how much will I gain when I actually start working on Rails!!

So next time when I code at work, I’ll probably ask myself ‘why I can’t do something like that in this language’ and the answer will surely help me understand the language and programming better.
