Use the Cookie. Discard Property which Gets or sets the discard flag set by the server. When

true, this property instructs the client application

not to save the Cookie on the users hard disk when a session ends.

Or

it can be turned off by mentioning cookie state= false in web.config file

CLR is .NET equivalent of Java Virtual Machine (JVM). It is the runtime that converts a MSIL code

into the host machine language code, which is then executed appropriately. The CLR is the

execution engine for .NET Framework applications. It provides a number of services, including:

Code management (loading and execution)

Application memory isolation

Verification of type safety

Conversion of IL to native code.

Access to metadata (enhanced type information)

Managing memory for managed objects

Enforcement of code access security

Control to validate & Error Message.

View State persist the values of controls of particular page in the client (browser) when post

back operation done. When user requests another page previous page data no longer available.

SessionState persist the data of particular user in the server. This data available till user close

the browser or session time completes.

=>CLS : cls is a standard for .net . cls is small set of specification to make all languages as a .net

compliant languages. cls make a use of cts and clr. if my languages (c#,vb.net,j#,vc++) wants to

be compliant language it has to follow cls standard.

=>CTS : Common Type System is also a standard like cls. If two languages (c# or vb.net or j# or

vc++) wants to communicate with eachother, they have to convert into some common type (i.e

Source, to display data in the combo box?

ComboBox.DataValueField = "ColumnName"

When we use Databind method for the Combo box we set Display Member and Display Value

property to column name.

and .NET Class Framework. None of this is possible without all the language sharing the same

data types. What this means is that an int should mean the same in VB, VC++, C# and all other

.NET compliant languages. This is achieved through introduction of Common Type System (CTS).

VB.NET

- It didn't have the XML Documentation.

- It didn't have the Operator Overloading.

- It didn't have the Pointer Type variables.

C#.NET

Well, if at that point you know that an error has occurred, then why not write the proper code

to handle that error instead of passing a new Exception object to the catch block? Throwing

your own exceptions signifies some design flaws in the project.

<asp:BoundColumn> is the tag you usually use to add a bound column. You may also use

<asp:TemplateColumn>

<ItemTemplate><%#...%></ItemTemplate>

</asp:TemplateColumn>

to add a bound column to a datagrid.

14. What tags do you need to add within the asp:datagrid tags to bind columns manually?

15. What tag do you use to add a hyperlink column to the DataGrid?

2. Interface - different class can implement same interface, resulting in different

implementations of interface methods.

3. Virtual methods - achieve runtime polymorphism.

17. Can a .NET web application consume Java web service?

Yes Offcourse.Actually Webservices are independent to language. it depends on WSDL and

SOAP. so any one can develope the Webservices anddisclose the wsdl and users can consume

the webservices.wsdl and soap both are xml based.. and all languages having xml parsing

capability and access to http protocol will be able to work with Webservices.

18. What are value types and reference types?

One of the disadvantages of using Visual Studio.NET and the .NET framework to develop

applications has been the lack of cross-platform support. Since the introduction of the .NET

framework and common language run time a few years ago, there have been a few projects

designed to bring the .NET framework to other platforms, including Linux and UNIX. The

DotGNU project is touted as the "Free software alternative to .NET" and encompasses a number

of projects, including DotGNU Portable .NET, which is designed to be used to compile and run C#

and C applications on a multitude of platforms, including GNU/Linux, FreeBSD, Mac OS X, and

Windows.One of the main features of the product is it's compatibility with EMCA standards for
