Small Talk

Now as we know how to create a project and already met the containers , we can start writing our application right away. And for this we will need to have a little concept about some basics of starting up an application. So today's post is on some elementary stuffs. May seem little bit boring but yet required!!  I will not repeat the words already said in bada API doc. I put the links of API doc with each description. Please read the doc and find some additional concerns in this post. First lets look at the following state diagram of an application.  Fig: Application life cycle. Collected from bada API doc. You probably already have seen this earlier. To start with an application we need to know exactly how to handle all the methods indicated in the diagram. Lets start with the first one... OnAppInitializing: At the time of launching your application the system will call OnAppInitializing method to initialize it. Take a look at the bada API doc for this...

Hmm... "Meet the Container !" :O What will be going on today!! :) Yes, today we will be looking on to all the containers. Because whatever application you develop you must need to deal with various types of containers. After all containers are the things that will hold all our component and show those on the screen.  Lets look at the following picture.  A total black window and a button saying "OK". At first lets find out how many components are there. What do you say? Well would you say like following? A dark black window. A button. is there anything else? Ok, lets look at the following one: ( Focus on "Frame" and "Form" only ) So you identified the "Frame" and "Form", right ? ( encircled ).  Yes these two are the most common companion for any BADA app developer. As you can see, your application must have a (only one) Frame on the very base. And then you need Form . An application can have multiple forms . Say yo...

Hurrayh!! You downloaded all the required stuffs right? ( Didnt get my point :( ? Please refer to the earlier post  ;) .  Hope you already installed the IDE with language packs. If so just run the IDE. Specify your BADA workspace where all your projects are supposed be resided. And continue... So! Now we are totally ready to go for the sample applications right? Its really easy and fun at the same time. Hope the BADA IDE is running behind your web browser. Now all you need to do is follow the steps given here to run some sample applications. Playing with these applications will make you familiar with this IDE, as well as give you a brief idea over the BADA SDK. Anyway, lets stop my tattling and start working. 1. Open the window of BADA SDK samples window. Go to “Window > Show view > Other”. This will show you a dialog like following. Select Bada SDK samples from this dialog. Click OK. The window of sample application list is opened. 2. Right click on any applica...

Today I was rambling in my web world on HTML 5 . Wondering about the great features offered. I think you also would like to start working on HTML 5 right now.

Have you ever used 'try' method in Ruby on Rails ( yes it is provided by rails not ruby ). I started loving this method so much. As the method name implies you will try to do something. If anyhow it fails it doesnt get fired on you by throwing any ugly exceptions. Look at the documentation . You may have already guessed the idea. But still lets work with a simple example. User.admins.first.try(:address).try(:reset) instead of User.admins.first.address.reset Here we are finding the first admin. Then accessing his/her address and then try to reset it. But what if that admin doesnt really have any address. I mean User.admins.first.address.first.address is nil. Then a NoMethodError for nil class would be waiting for you. But with the try you are safe. WHY? Actually try does nothing but invoking the Object#send method with the function name and the passed parameters. You can even pass a block through try. And apart from this Object#try method, you will have a N...

Did you ever try Highcharts for showing any kind chart data in your web application? Its great! Recently they released a newer version with lot more performance improvement and new features. Im talking about the version 2.0.0. Find it at http://www.highcharts.com/download . By the time you are reading this article if you find more upgraded version of highcharts, then of course it will be of more fun. Share it through comments :D Courtesy by Highcharts.com Just look at the Demo page of it. You will find lots of different kind of charts over there. Choose anyone according to your need. The first reason why I like Highchart is it totally based on javascript. Earlier I used openflash chart(OFC)  which is really slow by its process of data showing. As OFC is based on flash, you will need the flash embed code first, then this flash code will request for the data to your server and then it will show the chart. Maladroit huh !! But here with the help of Highcharts you will be...
