presentation on .net framework

1. Presentation

2. What is the .Net Framework
 Primarily a development platform (mostly effects
application development)
 Consists of two main parts
 Common Language Runtime
 .Net Framework Class Library

3. CLR (Common Language Runtime)
 Provides a “runtime environment” for the execution of
code written in ANY .Net Language
 “Manages”
 The overall execution of .Net code
 Inheritance, Memory, Debugging, and application
development across Multiple languages

4. Compilation of .Net code
 All .Net languages are first compiled into an intermediate
language called MSIL or IL (Microsoft Intermediate
Language)
 The MSIL is then “Just In Time” (JIT) compiled at first
execution of the code and managed by the CLR
 All MSIL or IL code can be compiled directly to native code
with the following
 Compiling native code will provide faster startup execution of the
code
 Performance during execution of the code will then be sacrificed
 During JIT Optimization is placed on the Managed Code in order to
improve performance at the time of execution

5. Code Compilation In .net

6. .Net Framework Class Library
 Provide a library of base classes that developers can
use in their own applications written in ANY .Net
language
 Because of the use of these base classes, Inheritance
can then be extensively used in languages that use the
.Net Framework

7. Visual Basic .Net
 General Features
 Additional Features of VB .Net

8. General features
 It is an object oriented language
 Students do better with this subject when they have a firm

understanding of objects
 In the past VB had objects but focus was not placed on them
 VB .Net use objects and inheritance with everything
Uses exception handling extensively
 New techniques are shown to the student for providing feedback
from their programs in order to help trouble shoot errors
 Like with most OOP languages, exceptions that are not handled will
cause programs to abnormally end or exit
Uses “generics” with creating classes and Sub programs
 Can use the top data type on inheritance of type Object
 Used for late binding of data types and is quite useful when
implementing stacks or queues of any data type (.Net 2.0)
Provides a quick way to develop heavy duty applications in a
windowing environment
It is a useful tool for developing event driven programs

9. Additional Feature of VB .Net
 Can create both windows applications and web applications at the click
of a mouse button
 The interface between the Databases and applications
 Are the same between web apps and windows apps
 All data are transferred between the apps in XML format regardless if it is a
web application or a windows application
 A copy of the data from the database is loaded into a data set.
 Persistent connections between the application and the database no longer
exists
 Every form is a class and new forms now have to be instantiated
 VB .Net is still not case sensitive

10. The Introduction to VB .Net
 Data Types in VB .Net
 Functions and Sub Procedures

11. Data Types in VB .Net
 Data Types and possible values
 Integer -> -2,147,483,648 (4 bytes)
 Double -> floating point numbers with 14 digits of accuracy

(8 Bytes)
Decimal -> decimal values ( 16 bytes replaced currency in 6.0)
Date -> the date (8 Bytes)
Byte -> 0 to 255 (1 Byte)
Char -> Unicode character (2 Bytes)
Boolean ->True or false value (2 Bytes)
Single -> floating point number with 6 digits of accuracy (4 bytes)
Short -> 2 byte integer
Long -> 8 byte integer
String -> an arrangement of alpha-numeric characters varies in
length
Object -> any data type 4 bytes

12. Functions and Sub procedures / Programs in
VB .Net (Methods)
 Functions and sub procedures must either have a sub or function

keyword in the function or sub procedure heading
They can be either public or private (following the same conventions in
OOP languages such as C++ or Java)
All parameters are passed by value by default in VB .Net
Parameters of any data type may be passed by reference
All Objects and arrays are passed by reference not value
All events are handled by a sub procedure in VB .Net
Functions return a value and Sub Procedures do Not

13. Microsoft SQL Basics
 Differences between MS SQL and Access
 Advantages of MS SQL

14. Differences between MS SQL and
Access
 SQL More Powerful than MS Access
 Larger data types are available
 Connection over a network provide access to multiple
clients
 A client is required to connect to the SQL Database

15. Advantages of MS SQL
 Can handle multiple users at one time
 Ideal for web sites and web applications
 Contain the BLOB (Binary Large Object) which
enables a user to store images in a database
 Larger numeric values can be stored in each field

16. Project Introduction
Hosiery Management System

17. Purpose
A Hosiery Management system is a Software that allows
the Hosiery Admin to Add, Delete and Update Design
The Purpose of making this project is to allow the Admin
of Hosiery or Factory to Manage all the parties, Design ,
Items , Employees . It allow the Admin or the User
Privileged by Admin to Add Design, Update Design,
Delete Design, Add Party, Update Party, Delete Party,
Add Item , Update Item, Delete Item, Add User , Change
Password etc

18. Drawbacks Of Existing System
 Existing system is made in downgrade visual basic 6
 It does not have Multi User Functionality
 Employee Attendance Procedure is Time
Consuming

19. Proposed System
 Multi user Account For user with Privileges
Provided by Admin
 Admin Panel In Admin Account
 Easy and Less Time Consuming Attendance
Procedure
 Comparatively Fast as .net Framework is used
