ViewBag v/s ViewData

Hi Friends,

If you go through ASP.NET MVC 3.0 framework then you will find  two frequently  used collection of data object which  used to pass data between control and views  and partial views. as both are doing similar functionality but has  some difference in that , so today , I would like to  put some difference of those and interoperability of that .

     V/s 

ViewData	ViewBag
It is dictionary of name/value pair  collection	It is dynamic  type object
This features exist since 1st release of ASP.NET MVC	This features available from ASP.NET MVC 3.0
This will work  in ASP.NET with .net 3.5 framework and above	This will work well with ASP.NET 4.0  with .net 4.0 framework and above
ViewData is faster compare to ViewBag	ViewBag is slower than ViewData
While retrieving  data from viewData in to view pages , one need to do proper type casting	While retrieving  data from viewbag in to view pages , one need  not to do  type casting
Hence it make code with lots of  type casting  fragments	Hence it make more clear code

The Changing Paradigm of Testing Industry

Software testing was an important turning point in the IT industry. It has changed the face of the software world today. In today's world, consumer expectations are very high on quality. They want customized access from anywhere, anytime, through any device and within no time and with no glitches. Satisfying such consumer needs and expectations of high quality were only possible by immense software testing. Testing has optimized software business products and has lessened the complexities faced by software developers. It has helped improve the overall software development life cycle.

Opening the event with a keynote session, Arun Kumar Singh, Vice President and Global Head Testing ,Financial Services, Wipro, threw some light on the importance of testing in today's business and tried to forecast where testing will go in years ahead. He spoke about 1.0, 2.0 and 3.0 phases of software testing.

How to decompile Android application to get sourcecode

Hi Friends,
reverse engineering is everywhere. but reverse engineering is meant for  code review of  vulnerable application. so I hope you guys will not  use this reverse engineering  tricks to do any illegal things.
all android application are running  on Dalvik , which is a Virtual Machine having register-base  architecture and different from Java Virtual Machine by sun-microsystem (and now by oracle ) which is stack machine.
hence all android application is consist of Dalvik Executable (.dex).  hence to convert those  android application( *.apk) to source code we have to follow below steps

(Note : apk is packing of  .dex  file and other resources.)

step to decompile

1) convert  .dex file format to  .class file
2) convert  .class file format to  java code file

1) android application will come with .apk file format. which contains  .dex file .
hence  to convert .dex file in to .class file ( and those compress .class files  are placed in .jar file)
one need to have .dex  to  .class file converter .(both are binary format)
you can download such  tool from below link.


 after downloading you need to extract them and it will have following files in you  file system.
