PALLIKONDESHWARASWAMY TEMPLE
THE ONLY PRODHOSHA KSHATRAM IN ENTIRE INDIA...

Sri Pallikondeshwara swamy temple at Suruthapalli. Chittor district in Andhra Pradesh 3kms from Uttukottai which is 50KM mark in our yatra...  We'll be visiting this temple on the second day 1:00 PM...

TamilNadu is the only place where the Lord Shiva is seen in the reclining position (sleeping position) also called as Neelakantha. It is here the Prodohosha Kala pooja has began since ages. By performing this Prodohosha Kaala pooja everyone will find complete solutions and get rid of poverty, ill health and will be bestowed with wealth and prosperity. This is one of the most auspicious pooja in the Hindu Dharma. Related to Shiva Skanda Purana
Prodhosha is the worship of Lord Shiva and Goddess Parvati when both are in an extremely propitious mood. Prayers during this period will fulfill one's desires and bring happiness in life.
The Prodhosha Kaala pooja is highly lauded by the scriptures and is very great sanctity and importance to the worshipers of Lord Shiva. The mere sight of the Deity in the temple during this period will destroy all the sins and bestow bountiful blessings and Grace upon the fortunate beholder. Even a single Bilva leaf (leaf taken from the stone wood apple tree) offered to the Lord at this unique, auspicious moment equals a hundred Mahapujas.
During the Prodhosha Kaala a large number of devotees gather to light the lamps. It is said that even to light a single wick of a lamp at this period is considered highly meritorious and productive of untold benefits both materialistic and spiritually. Most fortunate and blessed is the person who performs the
 Prodhosha Kaala pooja, Lord Shiva showers His choicest Grace and blessings on him in a very short period.

According to Sthalapurana (history of the place), it is said that Asuras (demons) and Devas (Gods) decided to consume the nectar from Kseerabthi (the milk ocean) to live immortal. Hence, they churned the ocean with the help of Vasuki (the celestial snake) and the hill Mandhara, with Gods on one side and demons on the other. Unable to tolerate the pressure, Vasuki spilled out the poison from his mouth. The Gods and demons then approached Lord Shiva to save them from the harmful effects of poison as it would have killed the leaving creatures on the earth and also Gods and demons. Lord Shiva transformed himself into Vishabhakarana Moorthy and swallowed the poison. He then started feeling little giddy. As he laid down, his consort. Goddess Parvati placed Lord's head on Her lap and gently pressed His neck and thus the poison remained in His throat without affecting His body. Hence Lord Shiva got the name as •Neelakantha.' (`Neela'- blue with poison and 'Kantha'- throat) (as Goddess Parvathi held the poison in the throat she is called as `Sarvamangalabigar.) It is in this place the Lord rested on the lap of Goddess Paravathi. During this time all the gods, maharishis and rishis assembled here for the well being of Lord Shiva and this place got its name as Suruttapalli. Surutta means assembly of Gods.


    The Devas and Asuras resumed their effort to get the nectar from the ocean on Lord Shiva's orders, after he regained consciousness and obtained the nectar on Dhwadashi (12th moon day). In that happiness, they forgot to thank Lord Siva who consumed the poison for everyone's well being. Realising their mistake, they prayed Him for forgiveness on Trayodasi (13th moon day) for which the Lord forgave them and in a happy mood, began His celestial dance (Shiva Tandavam) between the horns of Nandi (the mount of Lord Shiva) where all the Gods, Goddess and sages joined Him. This moment is celebrated as Pradosham every fortnight and hence Pradosha Pooja is said to have originated from this temple. It is believed that during Pradosha Punya Kaalam, anyone who offers prayers will attain shanti (peace), sakala sowbhagyam (Complete Happiness) and will be comforted from the obstacles of life. Even Lava and Kusha. who unknowingly fought with their father Lord Rama, over Aswamedha yagna horse, came to this temple along with Sage Valmiki. to worship Lord Siva and to get rid of their sins. Another prominence of Suruttapalli is that most of the deities are present with their consorts in their respective temples...

Interview Questions on ASP.NET

1. Describe the role of inetinfo.exe, aspnet_isapi.dll andaspnet_wp.exe in the page loading process.
inetinfo.exe is the Microsoft IIS server running, handling ASP.NET requests among other things. When an ASP.NET request is received (usually a file with .aspx extension), the ISAPI filter aspnet_isapi.dll takes care of it by passing the request to the actual worker process aspnet_wp.exe.

2. What’s the difference between Response.Write() andResponse.Output.Write()?
Response.Output.Write() allows you to write formatted output.

3. What methods are fired during the page load?
Init() - when the page is instantiated
Load() - when the page is loaded into server memory
PreRender() - the brief moment before the page is displayed to the user as HTML
Unload() - when page finishes loading.

4. When during the page processing cycle is ViewState available?
After the Init() and before the Page_Load(), or OnLoad() for a control.

5. What namespace does the Web page belong in the .NET Framework class hierarchy?
System.Web.UI.Page

6. Where do you store the information about the user’s locale?
System.Web.UI.Page.Culture

7. What’s the difference between Codebehind="MyCode.aspx.cs" andSrc="MyCode.aspx.cs"?
CodeBehind is relevant to Visual Studio.NET only.

8. What’s a bubbled event?
When you have a complex control, like DataGrid, writing an event processing routine for each object (cell, button, row, etc.) is quite tedious. The controls can bubble up their eventhandlers, allowing the main DataGrid event handler to take care of its constituents.

9. Suppose you want a certain ASP.NET function executed on MouseOver for a certain button. Where do you add an event handler?
Add an OnMouseOver attribute to the button. Example: btnSubmit.Attributes.Add("onmouseover","someClientCodeHere();");

10. What data types do the RangeValidator control support?
Integer, String, and Date.

11. Explain the differences between Server-side and Client-side code?
Server-side code executes on the server. Client-side code executes in the client's browser.

12. What type of code (server or client) is found in a Code-Behind class?
The answer is server-side code since code-behind is executed on the server. However, during the code-behind's execution on the server, it can render client-side code such as JavaScript to be processed in the clients browser. But just to be clear, code-behind executes on the server, thus making it server-side code.

13. Should user input data validation occur server-side or client-side? Why?
All user input data validation should occur on the server at a minimum. Additionally, client-side validation can be performed where deemed appropriate and feasable to provide a richer, more responsive experience for the user.

14. What is the difference between Server.Transfer and Response.Redirect? Why would I choose one over the other?
Server.Transfer transfers page processing from one page directly to the next page without making a round-trip back to the client's browser. This provides a faster response with a little less overhead on the server. Server.Transfer does not update the clients url history list or current url. Response.Redirect is used to redirect the user's browser to another page or site. This performas a trip back to the client where the client's browser is redirected to the new page. The user's browser history list is updated to reflect the new address.

15. Can you explain the difference between an ADO.NET Dataset and an ADO Recordset?
Valid answers are:
· A DataSet can represent an entire relational database in memory, complete with tables, relations, and views.
· A DataSet is designed to work without any continuing connection to the original data source.
· Data in a DataSet is bulk-loaded, rather than being loaded on demand.
· There's no concept of cursor types in a DataSet.
· DataSets have no current record pointer You can use For Each loops to move through the data.
· You can store many edits in a DataSet, and write them to the original data source in a single operation.
· Though the DataSet is universal, other objects in ADO.NET come in different versions for different data sources.

16. What is the Global.asax used for?
The Global.asax (including the Global.asax.cs file) is used to implement application and session level events.

17. What are the Application_Start and Session_Start subroutines used for?
This is where you can set the specific variables for the Application and Session objects.

18. Can you explain what inheritance is and an example of when you might use it?
When you want to inherit (use the functionality of) another class. Example: With a base class named Employee, a Manager class could be derived from the Employee base class.

19. Whats an assembly?
Assemblies are the building blocks of the .NET framework. Overview of assemblies from MSDN

20. Describe the difference between inline and code behind.
Inline code written along side the html in a page. Code-behind is code written in a separate file and referenced by the .aspx page.

21. Explain what a diffgram is, and a good use for one?
The DiffGram is one of the two XML formats that you can use to render DataSet object contents to XML. A good use is reading database data to an XML file to be sent to a Web Service.

22. Whats MSIL, and why should my developers need an appreciation of it if at all?
MSIL is the Microsoft Intermediate Language. All .NET compatible languages will get converted to MSIL. MSIL also allows the .NET Framework to JIT compile the assembly on the installed computer.

23. Which method do you invoke on the DataAdapter control to load your generated dataset with data?
The Fill() method.

24. Can you edit data in the Repeater control?
No, it just reads the information from its data source.

25. Which template must you provide, in order to display data in a Repeater control?
ItemTemplate.

26. How can you provide an alternating color scheme in a Repeater control?
Use the AlternatingItemTemplate.

27. What property must you set, and what method must you call in your code, in order to bind the data from a data source to the Repeater control?
You must set the DataSource property and call the DataBind method.

28. What base class do all Web Forms inherit from?
The Page class.

29. Name two properties common in every validation control?
ControlToValidate property and Text property.

30. Which property on a Combo Box do you set with a column name, prior to setting the DataSource, to display data in the combo box?
DataTextField property.

31. Which control would you use if you needed to make sure the values in two different controls matched?
CompareValidator control.

32. How many classes can a single .NET DLL contain?
It can contain many classes.


Web Service Questions

1. What is the transport protocol you use to call a Web service?
SOAP (Simple Object Access Protocol) is the preferred protocol.

2. True or False: A Web service can only be written in .NET?
False

3. What does WSDL stand for?
Web Services Description Language.

4. Where on the Internet would you look for Web services?
http://www.uddi.org

5. True or False: To test a Web service you must create a Windows application or Web application to consume this service?
False, the web service comes with a test page and it provides HTTP-GET method to test.


State Management Questions

1. What is ViewState?
ViewState allows the state of objects (serializable) to be stored in a hidden field on the page. ViewState is transported to the client and back to the server, and is not stored on the server or any other external source. ViewState is used the retain the state of server-side objects between postabacks.

2. What is the lifespan for items stored in ViewState?
Item stored in ViewState exist for the life of the current page. This includes postbacks (to the same page).

3. What does the "EnableViewState" property do? Why would I want it on or off?
It allows the page to save the users input on a form across postbacks. It saves the server-side values for a given control into ViewState, which is stored as a hidden value on the page before sending the page to the clients browser. When the page is posted back to the server the server control is recreated with the state stored in viewstate.

4. What are the different types of Session state management options available with ASP.NET?
ASP.NET provides In-Process and Out-of-Process state management. In-Process stores the session in memory on the web server. This requires the a "sticky-server" (or no load-balancing) so that the user is always reconnected to the same web server. Out-of-Process Session state management stores data in an external data source. The external data source may be either a SQL Server or a State Server service. Out-of-Process state management requires that all objects stored in session are serializable.

DOTNET Framwork

.NET Framework 4.0:

Microsoft announced the .NET Framework 4.0 on 29 September 2008. The Public Beta was released on 20 May 2009. Some focuses of this release are:

* Parallel Extensions to improve support for parallel computing, which target multi-core or distributed systems. To this end, they plan to include technologies like PLINQ (Parallel LINQ), a parallel implementation of the LINQ engine, and Task Parallel Library, which exposes parallel constructs via method calls.
* Visual Basic and C# languages innovations such as statement lambdas, implicit line continuations, dynamic dispatch, named parameters, and optional parameters.
* Full support for IronPython, IronRuby, and F#.
* Support for a subset of the .NET Framework and ASP.NET with the "Server Core" variant of Windows Server 2008 R2.
* Support for Code Contracts.
* Inclusion of the Oslo modelling platform, along with the M programming language.

In 28 July 2009, a second release of the .NET Framework 4.0 beta was made available with experimental software transactional memory support. Whether this functionality will be available in the final version of the framework has not been confirmed.

In conjunction with .NET Framework 4.0, Microsoft will offer a set of enhancements, codenamed Dublin, for Windows Server 2008 application server capabilities. Dublin will extend IIS to be a "standard host" for applications that use either WCF or WF

.NET Framework 3.5:

Version 3.5 of the .NET Framework was released on 19 November 2007, but it is not included with Windows Server 2008. As with .NET Framework 3.0, version 3.5 uses the CLR of version 2.0. In addition, it installs .NET Framework 2.0 SP1, (installs .NET Framework 2.0 SP2 with 3.5 SP1) and .NET Framework 3.0 SP1 (installs .NET Framework 3.0 SP2 with 3.5 SP1), which adds some methods and properties to the BCL classes in version 2.0 which are required for version 3.5 features such as Language Integrated Query (LINQ). These changes do not affect applications written for version 2.0, however.

As with previous versions, a new .NET Compact Framework 3.5 was released in tandem with this update in order to provide support for additional features on Windows Mobile and Windows Embedded CE devices.

The source code of the Base Class Library in this version has been partially released (for debugging reference only) under the Microsoft Reference Source License

.NET Framework 3.0:

.NET Framework 3.0, formerly called WinFX, was released on 21 November 2006. It includes a new set of managed code APIs that are an integral part of Windows Vista and Windows Server 2008 operating systems. It is also available for Windows XP SP2 and Windows Server 2003 as a download. There are no major architectural changes included with this release; .NET Framework 3.0 uses the Common Language Runtime of .NET Framework 2.0. Unlike the previous major .NET releases there was no .NET Compact Framework release made as a counterpart of this version.

.NET Framework 3.0 consists of four major new components:

* Windows Presentation Foundation (WPF), formerly code-named Avalon; a new user interface subsystem and API based on XML and vector graphics, which uses 3D computer graphics hardware and Direct3D technologies. See WPF SDK for developer articles and documentation on WPF.
* Windows Communication Foundation (WCF), formerly code-named Indigo; a service-oriented messaging system which allows programs to interoperate locally or remotely similar to web services.
* Windows Workflow Foundation (WF) allows for building of task automation and integrated transactions using workflows.
* Windows CardSpace, formerly code-named InfoCard; a software component which securely stores a person's digital identities and provides a unified interface for choosing the identity for a particular transaction, such as logging in to a website.

.NET Framework 2.0

Released with Visual Studio 2005, Microsoft SQL Server 2005, and BizTalk 2006.

* The 2.0 Redistributable Package can be downloaded for free from Microsoft, and was published on 22 January 2006.
* The 2.0 Software Development Kit (SDK) can be downloaded for free from Microsoft.
* It is included as part of Visual Studio 2005 and Microsoft SQL Server 2005.
* Version 2.0 without any Service Pack is the last version with support for Windows 98 and Windows Me. Version 2.0 with Service Pack 2 is the last version with official support for Windows 2000 although there have been some unofficial workarounds published online to use a subset of the functionality from Version 3.5 in Windows 2000. Version 2.0 with Service Pack 2 requires Windows 2000 with SP4 plus KB835732 or KB891861 update, Windows XP with SP2 or later and Windows Installer 3.1 (KB893803-v2).
* It shipped with Windows Server 2003 R2 (not installed by default).

.NET Framework 1.1

This is the first major .NET Framework upgrade. It is available on its own as a redistributable package or in a software development kit, and was published on 3 April 2003. It is also part of the second release of Microsoft Visual Studio .NET (released as Visual Studio .NET 2003). This is the first version of the .NET Framework to be included as part of the Windows operating system, shipping with Windows Server 2003. Mainstream support for .NET Framework 1.1 ended on 14 October 2008, and extended support ends on 8 October 2013. Since .NET 1.1 is a component of Windows Server 2003, extended support for .NET 1.1 on Server 2003 will run out with that of the OS - currently 14 July 2015.

.NET Framework 1.0:
This is the first release of the .NET Framework, released on 13 February 2002 and available for Windows 98, Me, NT 4.0, 2000, and XP. Mainstream support by Microsoft for this version ended 10 July 2007, and extended support ended 14 July 2009.
