Console applications can take only text based input and 
also can give output in text format only. 

Hence, console applications are best suited for 
applications that should run as a scheduled job.

Also, console applications are the best choice while 
learning a language.

consol is used only for web application

Console is used if u want to Create a Windows Based 
application. First Ans is correct.Second is wrong.

Sub Main()
        Dim x, y As Integer
        Console.Write("Enter value of x: ")
        x = Console.ReadLine()
        Console.Write("Enter value of y: ")
        y = Console.ReadLine()
        Console.Write("Sum x+y = ")
        Console.WriteLine(x + y)
        Console.ReadLine()
    End Sub

Sub Main()
        Dim x, y, sum As Integer
        Console.WriteLine("Enter two numbers")
        x = Console.ReadLine()
        y = Console.ReadLine()
        sum = x + y
        Console.WriteLine("Sum = " & sum)
        Console.ReadLine()
        '& is used for concatenation
    End Sub

MSIL stands for Microsoft Intermediate Language.

When compiling the source code to managed code in dotnet 
environment, the compiler translates the source into 
Microsoft intermediate language (MSIL). This is a CPU-
independent set of instructions that can efficiently be 
converted to native code. Microsoft intermediate language 
(MSIL) is a translation used as the output of a number of 
compilers. It is the input to a just-in-time (JIT) 
compiler. The Common Language Runtime includes a JIT 
compiler for the conversion of MSIL to native code.

Microsoft Intermediate Langage.
All .net compilers converts the compled code into MSIL

As the Web.Config file defines application level
settings.It'll override the settings of the machine.config
file.So the session timeout as 30 mins defined in web.config
file is set to the application.

You have to use this DSN name (in your case it is sonia) in 
your VB code wherever you wish to establish a connection 
between your VB application and your SQL server 2K database.

You have to create the DSN programatically by using some 
code.

You can used DSN Less Code here (which is more usefull 
andimportant insteated of using DSN Coz when you run that 
Application on Different PC, then you have to crete DSN 
again..)
DSN Less Code for Connection MS ACCESS: or can connect any 
db just need to change its provider:
dim con as new adodb.Connection 
con.open "provider=microsoft.jet.oledb.4.0;" & "Data 
Source= ur db path (there is no space btn Folder and File 
Name)"

steps i Follow-
1) Go to Control panel-->Admintrative Tools-->Double -click
Data sources(ODBC)-->click Add button-->I choose SQL server
(last option), Is it right or wrong option for connecting 
to SQL 2000.Then a new screen appears Create a New 
dataSource-->in name textbox,we can write anyname--Right or 
wrong. suppose i enter sonia, & my server name is .,so I 
enter . in server & click next button-->On the Next screen 
i have checked the option With Sql server authentication--
>Login Id-sa, Password-->Blank-->Click next button-->Next--
>Finish-->Then I click on button Test Data source-->Mesage 
Comes TESTS COMPLETED SUCCESSFULLY-->OK-->OK-->Ok.

These steps we have to do or not for Connectivity using 
ODBC.
If yes,then what after these steps we have to do??Plz reply 
me early ??Thx in advance.

When a connection is opened for the first time a connection 
pool is created. Connection pooling works only when the 
connection string is same. New connection object is not 
opened for two connection requests having same connection 
string. This is called as connection pooling.

Connection pooling increases the performance of Web 
applications by reusing active database connections instead 
of creating a new connection with every request. 

Connection pool manager maintains a pool of open database 
connections. When a new connection requests come in, the 
pool manager checks if the pool contains any unused 
connections and returns one if available. If all 
connections currently in the pool are busy and the maximum 
pool size has not been reached, the new connection is 
created and added to the pool.

When the pool reaches its maximum size all new connection 
requests are being queued up until a connection in the pool 
becomes available or the connection attempt times out.

Apart From def of Connection Pooling
Connection pooling has 4 parameters:

1.)Connect Timeout - controls the wait period in seconds 
when a new connection is requested, if this timeout 
expires, an exception will be thrown. Default is 15 
seconds. 
2.)Max Pool Size - specifies the maximum size of your 
connection pool. Default is 100. Most Web sites do not use 
more than 40 connections under the heaviest load but it 
depends on how long your database operations take to 
complete. 
3.)Min Pool Size - initial number of connections that will 
be added to the pool upon its creation. Default is zero; 
however, you may chose to set this to a small number such 
as 5 if your application needs consistent response times 
even after it was idle for hours. In this case the first 
user requests won't have to wait for those database 
connections to establish. 
4.)Pooling - controls if your connection pooling on or off. 
Default as you may've guessed is true. Read on to see when 
you may use Pooling=false setting.

Its available only in VS 2005...Just Drag and Drop from the
toolbox and Write code....

Everthing that asp.net does is through the windows account 
that is defined in machine .config which is aspnet.
Now if you want your application alone to run in a 
different account, you can change this identity to be 
changed temporarily so that the asp.net will run in another 
account(provided it is a windows account)

impersonation is the process of assigning a user account to
an unknown user.By default, the anonymous access account is
named IUSER_machinename. This account can be use to control
anonymous users' access to resources on the server.
This mechanism allows a server process to run using the
security credentials of the client. When the server is
impersonating the client, any operations performed by the
server are performed using the client's credentials.
Impersonation does not allow the server to access remote
resources on behalf of the client.

you can enable the impersonation by adding below entry in 
your application config file.

<identity impersonate="true"
          userName="domain\user" 
          password="password" />

Impersonation is nothing but identity of a client.

I know one third party that we are using in our 
project .The name of the Third Party Tool is Telerik 
Controls.If any body wants to know more about please visit 
the site www.telerik.com.

there are more third party tools for .net,  we are using 
entity spaces.. also there are tools like doodads etc..

byvalor byref

Value Parameters or default parameter
Reference Parameter
out put Parameter
Parameter(Params) Arrays

there are ways where we can pass the parameters in c#,which 
are:
   call by value
   call by refernce
   call by pointer using keyword 'out'

const is used to create a constant value which will be
constant throuout the class

static is used for a commaon variable for all objects, it is
not part of a object, it is a part of class, every object
will share this value,
read,

there are many situation in which we want to intialize the
value of a constat variabl at run time, in which we can have
different values for different objects, with the help of
readonly we can define the value of any object at runtime
which will not be changed later

const is the keyword where we can intialize the variable 
with some value which is constant throughout the program it 
cannot be changed.
static is the keyword which is intialized at complile time 
and had to change at compile time only.
readonly is for the varible which is readonly cant be 
changed.

1. we can initialize constant variable only at the 
declaration where as readonly varaiable can be initialized 
at either declaration or in constructor.

2. we can't use static modifier for the const variable 
where as readonly variable can be declared as static

.Net has a different version called as MONO which is 
platform indipendent.

Gridview,Repeater and Datalist all are Data controls, which 
are used to display the data.

Gridview:It contains predifined Structure
Repeater,Datalist Controls are Userdefined Based on 
Templates

Repeater having better performance compared to Gridview and 
datalist.But, almost repeater can be done with custom 
coding only.
