PART 1 INTRODUCTION

• HISTORY OF LANGUAGE

• Microsoft introduced their Microsoft.Net
  initiative at the Professional Developers
  Conference (PDC) in Orlando,Florida in July 2000.
• VB.Net is a Microsoft-created object-oriented
  programming language
• VB.Net would be sequel to Visual Basic 6.0 is
  totally different language.
• VB.Net is designed to create
• .Net Applications
• Web Applications
• Web Services
• Windows Application

• Run on the Microsoft Windows operating system

3
PART 1 INTRODUCTION

• PROGRAMMING PARADIGM

• VB.Net implemented on the Microsoft.Net
  framework and runs on windows operating system
• Developers use Visual Studio.Net as their
  integrated development environment (IDE))
• Totally object-oriented programming
• The core concept behind object-orientation is
  encapsulation
• The functionality is wrapped up in a self
  contained manner.

• Application Area suited

• Building desktop application Inventory
  Systems,Banking Systems etc
• Web Applications E-commerce,E-Learning,E-Banking
  etc

PART 1 INTRODUCTION

• Features

Powerful Windows Based Application Menu editor,
automatic control anchoring and docking Offers
fast automatic formatting of code as
typing Enhanced object browser and XML
designer Building Web-based Applications Enhanced
HTML Editor for working with complex Web pages

PART 1 INTRODUCTION

• Features

Powerful,Flexible,Simplified Data Access ADO.NET
enables data binding to any database,as well as
classes,collections and arrays. XML Web
Services Enable to call components running on any
platform using open internet protocols Com
Interoperability Enables to leverage existing
code assets and offers seamless communication
between VB 6.0 and VB.Net

PART 2 Description of Language
Scalar data objects are either real or complex
values. The values of scalar can be assigned to
variable names chosen by user, such as for
numeric, boolean, characters, enumerations and etc
Below are comparison between VB.Net and Java
Numeric Values
9
PART 2 Description of Language
Composite objects is an object designed as
composition of one or more similar objects.
Utilize multiple objects in the same way, and
often have nearly identical code to handle it,
such as for string or pointers.
Below are comparison between VB.Net and Java
Strings
10
PART 2 Description of Language
Structured objects is storing hierarchical data
within a single file, such as Array, Records,
List and sets
Below are comparison between VB.Net and Java
Array Values
11
PART 2 Description of Language
Abstract data types set of data values and
associated operations that are precisely
specified independent of any particular
implementation ,sucah as classes.
Below are comparison between VB.Net and Java
Classes

PART 3 FINAL EVALUATION

• SUMMARY OF EVALUATION
• Do you have any basics to agree or disagree with
  any claims made of its security,portability,effici
  encyextensibility/maintainability
• I agree that Vb.net is true oop, easier
  deployment, better interoperability and better
  environment to develop both tradisional and web
  applications.
• What aspect of this language did you find most
  difficult to learn/understand?
• Aspect which is difficult to learn will be
  developing a distributed system, using XML
  functions that running on different computers
  across the world.
• How would you rate the programming environment?
  Compiler/interpreter messages?
• The programming environment is a sophisticated
  because the debuggers can target the Common
  Language Runtime
• Would you use this language again and if so what
  for ? If not,what would you choose to use instead
  and why
• I will use this language again for many useful
  windows applications
• Design mistakes ( in your opinion or the opinion
  of others)? Have they been corrected in other
  languages that were a follow-on. What if anything
  is missing in your opinion ?
• Browser-based clients are difficult to create and
  offer limited user interfaceCan use Java applets
  to make the user interface richer and more
  functional.
