When compiling to managed code, the compiler translates 
your source code into Microsoft intermediate language 
(MSIL), which is a CPU-independent set of instructions that 
can be efficiently converted to native code. MSIL includes 
instructions for loading, storing, initializing, and 
calling methods on objects, as well as instructions for 
arithmetic and logical operations, control flow, direct 
memory access, exception handling, and other operations. 
Before code can be run, MSIL must be converted to CPU-
specific code, usually by a just-in-time (JIT) compiler. 
Because the common language runtime supplies one or more 
JIT compilers for each computer architecture it supports, 
the same set of MSIL can be JIT-compiled and run on any 
supported architecture. When a compiler produces MSIL, it 
also produces metadata. Metadata describes the types in 
your code, including the definition of each type, the 
signatures of each type’s members, the members that your 
code references, and other data that the runtime uses at 
execution time. The MSIL and metadata are contained in a 
portable executable (PE) file that is based on and extends 
the published Microsoft PE and common object file format 
(COFF) used historically for executable content. This file 
format, which accommodates MSIL or native code as well as 
metadata, enables the operating system to recognize common 
language runtime images. The presence of metadata in the 
file along with the MSIL enables your code to describe 
itself, which means that there is no need for type 
libraries or Interface Definition Language (IDL). The 
runtime locates and extracts the metadata from the file as 
needed during execution

It is cpu independent language.It is only understand by CLR.
due this language(MSIL) vb.net application can run on any 
platform on which .net framework is present.

It is a Microsoft Intermediatary Language which helps to 
convert programming language into machine's native language 
at the time of compilation.

MSIL IS Microsoft Intermediate language.It manage code when
compiling. the compiler translate your source code into
microsoft intermediate language.It must be converted cpu
specific code, usually by a jit(just in time)

Vb.net is a programming language that is available in 
Visual Studio. Net. It contains features of visual basic 
which is event based programming language and also includes 
object oriented concepts.

vb.net is framework which contains oop concept

VB.Net is based on OOPS concept and have a framwork 
architecture with language independence

vb.net is a programming language of .net frame work which 
is based on oops concepa

VB.Net is a programming language which is an extension of
Visual Basic to make it compliant to the Dot Net Framework.

Also VB.Net is fully Object Oriented unlike Visual Basic and
everything in VB.Net is an object.

As it is compliant to the Dot Net Framework VB.Net can make
full use of Framework Class Library provided by dot Net
Framework.

VB.Net is an IDE.

Vb.Net Is A Programming language And It Based on Oops 
Concept. And It
Contains features of visual basic which is event based 
programming language And
Vb.net application can run on any platform on which .net 
framework is present.

vb.net offers a capabilities for developing windows application, console 
application as well as web application.

vb.net is implimentation and specification of microsoft 
which is specialy used for web development

Whereas in ASP.Net we can use RegularExpression Validator to
validate the date value.  But in VB.NET we have to use Class
RegEx.  

If Regex.IsMatch(txtDate,

VS.NET contains .NET FRAMEWORK includes Window form, Web 
Form, Base Class Libraries and CLR.

Visual Studio.net contains .NET framework solutions.  And it
includes Windows, Web, and Console applications.

Visual Studio .Net is basically a framework which makes easy
development of codes written in Various programming languages..
It contains two things
1.Framework Class Library:It contains various classes
managed within various namespaces.

2.Common Language Runtime:CLR is the execution engine which
helps in compiling the IL code into machine code,takes care
of security issues and many other critical tasks.
Web pages,windows apps,console applications,Class libriaries
are various options which can be created using VS.net

Based on Framework understanding and OOPS Concepts,
Use of Diffrent Component Library

MSIL

not MSIL 
C# , J# , ASP.NET, VB.NET, and other 13 intermediat lanuages

.net supports CLS i. e. Common language type. its a 
microsofts feature to bring all languages near one roof.
When You compile .net code it dosen't converted into binary 
language, it converted into IL (Intermidate Language) also 
known as MSIL. And from IL to binary language converted at 
run time, CLR manages this process. At the runtime also it 
not converts whole project at time to binary, only converts 
that part which is going to execute, this the performance 
of project increases. This IL can use any lanuage which is 
member of that .net studio. The assemblies (ExE, DLL) are 
also in IL form. So u can use any EXE or DLL created in 
vb.net in c#.net also.

which converts native code into byte code i.e machine 
understandable code.

MSIL is MicroSoft Intermediate Language. When we 
compile .Net applications, its complied to MSIL, which is 
not machine read language. Hence Common Language Runtime 
(CLR) with JustIn Time Complier (JLT), converts this MSIL 
to native code (binary code), which is machine language.

It is cpu independent language.It is only understand by 
CLR.due this language(MSIL) vb.net application can run on 
any platform on which .net framework is present.

It converts the code into bytecode. it is a service that 
runs under the CLR. When we compile our code it gets 
compiled into IL(Previously Known as MSIL).

Correct Answer is MSIL and it is 100% sure.

All .net code is compiled to IL(is also called as MSIL)  
which doesn't understand machine.CLR uses JIT compiler to 
convert IL into Executable file.

when we compile a file in cscharp through csc compiler it
reach at intermidiate state where it neighter in souce code
nor in machine native code.it can be exe or Dll which can
later be used in diffrent language.

MSIL (Microsoft Intermediate Language) or CIL (Common 
Intermediate Language). All .NET source code is compiled to 
IL. This IL is then converted to machine code at the point 
where the software is installed, or at run-time by a Just-
In-Time (JIT) compiler.

Convert the .net programming language code into compiler 
understand code

When you compile a progam developed in a language that targets the CLR, instead on compiling the source code into machine-level code, the compiler translates it into IL to ensure interoperability between applications developed in different programming languages, such as Visual Basic or Visual C#. Intermediate Language is CPU-independent. This means that the code can be executed from any platform that supports the .NET CLR.

Following are the disadvantage of VB :
1. VB is not object oriented.
2. VB DLL does not support side-by-side execution
3. Deployment is time consuming as all the components must 
be registered in the Windows registry.

1.The VB support OOP concepts,but not support fully.

2.VB does not support exception handling.

3.No multithreading mechanism.

kamal....

The dlls of the VB is mapped with the Registry so the 
overhead on the registry is increased.
Vb is not Object oriented bcoz it don't hv classes
it hv only the functions so we hv to learn the functions 
for the programing we can't import the classs.
vb is only for the application programing but nw the 
scenario is for web applications?

VB dosent use magic

1,supports Threading
2,powerful Exception handling
mechanism
3,having support for the
console based applications
4,More than one version of
dll is supported

1. VB is object based while Vb.net is Object oriented
2. VB.net using OO functionality like inheritenca, 
Excepetional handling, etc
3.VB .net is strong type casting whicv VB lack
4.VB.net supports multi threading....

1. vb.net support Multi-Threading.
2. vb.net is used as language in asp.net
3. vb.net is OO while vb is object based.
4. vb.net support exception handling.

1. VB.net is object oriented
2. VB.Net can be used in Managed Code
3. It supports inheritance, implement

1.supports Threading
2.powerful Exception handling mechanism
3.having support for the console based applications
4.vb has its own interpreter and vb.net has compiler(CLR).
5.VB is object based while Vb.net is Object oriented

yes VB.NET ia an object oriented.

vb.net is object oriented concept.it is supports to 
inheritence but it donot support to multiple inheritance.

Vb.net supports all inheritance

1)single inheritance
It means Single class inheriting to single child classes
2)multiple inheritance
multiple classess inherits to single classes
3)Multilevel  Inheritance
Single class inherits to one class that class inheritd to 
single another class
4)Heirarichal inheritance 
Single class inherits to Multiple classes
5)Hybrid Inheritance
Single class inherits to different classess and that 
classes inherits to one class

With respect to Answer 3 of this Question.
I think following are still not clear-

4)Heirarichal inheritance 
Single class inherits to Multiple classes

This is not possible in .NET.
5)Hybrid Inheritance
Single class inherits to different classes and that class 
inherits to one class

It should be Single class inherits to different class (not,
classes) and that class inherits to one class

yes,vb.net is object oriented.
vb.net supports only
1)single level inheritance/simple inheritance
2) multi level inheritance
3)hierachical inheritance

vb.net doesn't supports
multiple,hybrid inheritance.

vb.net is not a object oriented. its a compiled language.

vb.net is not pure object oriented as compare C#.it is 
support inheritance concepts but not supports to multiple 
inheritance

Answer 4 & 5 is the correct one. Pls ignore all other answers.

VB.Net is an Object Oriented Language.
It doesn't support multiple inheritance. For this purpose, 
interfaces are introduced. 
VB.Net supports multiple interfaces

vb.net is not a object oriented. its a compiled language.

- the most dumbest answer. Please don't give wrong answers 
when you are not sure. It will misguide the readers.

hey hari,i have faced the interview Question what are 
interfaces?
  I answer Vb.net doesn't supports multiple inheritance,but 
it can be achieved in .net using interfaces. Interfaces are 
silmilar to class,that contain methods.
  but they do not provide any implementation for these 
methods. 

Then they asked WHY VB.NET DOESN't SUPPORTS MULTIPLE 
INHERITANCE??
If u know Can u plz answer!!!!!!!!!

assemblies contain more then one dll an exe and executable 
code

BOTH VB DLL AND ASSEMBLIES ARE REUSEABLE CODE
BUT WHEN YOU CREATE TWO DLLS WITH SAME NAME IN VB
VERSIONING PROBLEM OCCURS IN VB

IN ASSEMBLES ARE INTRODUCED TO AVOID VISIONIG PROBLEM
IN .NET

Assemblies can contain DLL and EXE both. Different versions 
of one DLL can be handeled by assemblies. They overcome the 
DLL Hell problem. Assemblies Contain Manifest and MetaData 
files. These are the seprate files that describes the 
Assembly and its attributes. 

VB DLL is inprocess.DLL run with an exe                   
where as DLL are not self executable. 
we can reuse DLLs .DLL are not platform independent
If we have more then one Versions of a DLL we can face DLL 
Hell Problem.

Assemblies can contain morethan one dll,exe and html file 
and they represents the resources,type definition and 
implementation of those types.

All most all languages support VB DLL(COM DLL).But
assemblies can support only in .Net frameworks..

VB doesn't support multithreading.

Its the fastest and an excellent application provided in
VB.net.  Due to which many operations can be done without
any lapse of time.  The system need not wait for an
application or any task to get completed, rather it runs
simultaneously.

VB6 does not support multithreading.
However, It is possible using Win32 API 
"CreateThread" function.

Keep it simple. User few timer, and some state. Or you can
do multi processes and asynchronous call too. But be careful
with slowness.
