Roll No: - 2107217 INTRODUCTION TO C#.NET

Why .NET?

1. Interoperability between languages and execution environments

2. Uniformity in schema or formats for Data Exchange using XML, XSL

3. Extend or use existing code that is valid

4. Programming complexity of environment is reduced

The .NET Framework is…

1. A component model for the internet

2. The new approach to building large scale distributed systems for the Internet

3. Provides the capability to integrate multiple devices

4. Built around the tools and protocols (XML, WSDL, SOAP, HTTP) that are

becoming standard on the Internet

The .NET in ASP.NET stands for the .NET Framework, a set of objects and blueprints from

Microsoft for building applications. All applications developed under the .NET Framework;

including ASP.NET applications, have certain key features that ensure compatibility, security,

and stability.

Common Language Runtime (CLR) is an environment that manages the execution of code. With

the .NET Framework and CLR, we write code and compile it. However, instead of compiling it

into the computer understands, we compile it into a language called Microsoft Intermediate

Language (MSIL). When we compile to MSIL, your application produce something called

metadata. This is descriptive information about your application. It tells what the application can

do, where it belongs, and so on. When you want to run your program, the CLR takes over and

compile the code once more into the computer’s native language. This way MSIL can go on any

type of computer. The CLR can speak many different computer languages and does all the

compiling for you. Once you compile your application, you can bring it to any other computer.

Roll No: - 2107217CLR also provides services such as error handling, security features, versioning and deployment

support, as well as cross-language integration. That means we can choose any language we want

to write our .NET applications, including ASP.NET applications.

The Creation of C#

While Java has successfully addressed many of the issues surrounding portability in the Internet environment, there are still features that it lacks. One is cross-language interoperability, also called mixed-language programming. This is the ability for the code produced by one language to work easily with the code produced by another. Cross-language interoperability is needed for the creation of large, distributed software systems. It is also desirable for programming software components, because the most valuable component is one that can be used by the widest variety of computer languages, in the greatest number of operating environments.

Another feature lacking in Java is full integration with the Windows platform. Although Java programs can be executed in a Windows environment (assuming that the Java Virtual Machine has been installed), Java and Windows are not closely coupled. Since Windows is the mostly widely used operating system in the world, lack of direct support for Windows is a drawback to Java.

To answer these and other needs, Microsoft developed C#. C# was created at Microsoft late in the 1990s and was part of Microsoft’s overall .NET strategy. It was first released in its alpha version in the middle of 2000. C#’s chief architect was Anders Hejlsberg. Hejlsberg is one of the world’s leading language experts, with several notable accomplishments to his credit. For example, in the 1980s he was the original author of the highly successful and influential Turbo Pascal, whose streamlined implementation set the standard for all future compilers.

C# is directly related to C, C++, and Java. This is not by accident. These are three of the most widely used and most widely liked programming languages in the world. Furthermore, at the time of C#’s creation, nearly all professional programmers knew C, C++, and/or Java. By building C# upon a solid, well-understood foundation, C# offered an easy migration path from these languages. Since it was neither necessary nor desirable for Hejlsberg to start from scratch, he was free to focus on specific improvements and innovations.

The family tree for C# is shown in Figure 1-1. The grandfather of C# is C. From C, C# derives its syntax, many of its keywords, and its operators. C# builds upon and improves the object model defined by C++. If you know C or C++, then you will feel at home with C#.

Roll No: - 2107217

Figure 1-1: The C# family tree

C# and Java have a bit more complicated relationship. As explained, Java is also descended from C and C++. It too shares the C/C++ syntax and object model. Like Java, C# is designed to produce portable code. However, C# is not descended from Java. Instead, C# and Java are more like cousins, sharing a common ancestry, but differing in many important ways. The good news, though, is that if you know Java, then many C# concepts will be familiar. Conversely, if in the future you need to learn Java, then many of the things you learn about C# will carry over.

C# contains many innovative features but some of its most important relate to its built-in support for software components. In fact, C# has been characterized as being a component-oriented language because it contains integral support for the writing of software components. For example, C# includes features that directly support the constituents of components, such as properties, methods, and events. However, C#’s ability to work in a mixed-language environment is perhaps its most important component-oriented feature.

The Evolution of C#

Following the original 1.0 release, C# has undergone two revisions. The first was version 1.1, which was a minor upgrade that did not add significantly to the language.Version 2.0 is a major release. It adds many new features and fundamentally expands the scope, power, and range of the language. Along with many small improvements, C# 2.0 includes 14 major additions to the language.

Roll No: - 2107217

The next major release of C# was 3.0.Beacuse of the many new features added by C# 2.0, one might have expected the development of C# to slow a bit,just to let programmers catch up, but this was not the case.With the release of C# 3.0,microsoft once again put C# on the cutting edge of language design,this time adding the set of innovative features that redefined the programming landscape. A more complete listing of the releases of the .NET Framework may be found on the .NET Framework version list.

Of these new features, the one that has the most effect on the language, and the most direct impact on programmers, is generics. Not only does it add an entirely new syntax element to the language, but it also greatly expands C#’s expressive power by enabling the creation of type-safe, reusable code. As a side-effect, the addition of generics has caused the Collections library to be greatly expanded.

What Is the .NET Framework?

The .NET Framework defines an environment that supports the development and execution of highly distributed, component-based applications. It enables differing computer languages to work together and provides for security, program portability, and a common programming model for the Windows platform. As it relates to C#, the .NET Framework defines two very important entities. The first is the Common Language Runtime (CLR). This is the system that manages the execution of your program. Along with other benefits, the Common Language Runtime is the part of the .NET Framework that enables programs to be portable, supports mixed-language programming, and provides for security.

The second entity is the .NET Framework class library. This library gives your program access to the runtime environment. For example, if you want to perform I/O, such as displaying something on the screen, you will use the .NET library to do it. If you are new to programming, then the term class may be new. Although it is explained in detail later in this book, for now a brief definition will suffice: a class is an object-oriented construct that helps organize programs. As long as your program restricts itself to the features defined by the .NET Framework class library, your programs can run anywhere that the .NET runtime system is supported. Since C# automatically uses the .NET Framework class library, C# programs are automatically portable to all .NET environments.

How C# Relates to the .NET Framework

Although C# is a computer language that can be studied on its own, it has a special relationship to its runtime environment, the .NET Framework. The reason for this is twofold. First, C# was initially designed by Microsoft to create code for the .NET Framework. Second, the libraries used by C# are the ones defined by the .NET Framework. Thus, even though it is possible to separate C# the language from the .NET environment, the two are closely linked. Because of this, it is important to have a general understanding of the .NET Framework and why it is important to C#.

Roll No: - 2107217

How the Common Language Runtime Works

The Common Language Runtime manages the execution of .NET code. Here is how it works: When you compile a C# program, the output of the compiler is not executable code. Instead, it is a file that contains a special type of pseudocode called Microsoft Intermediate Language (MSIL). MSIL defines a set of portable instructions that are independent of any specific CPU. In essence, MSIL defines a portable assembly language. One other point: Although MSIL is similar in concept to Java’s bytecode, the two are not the same.

It is the job of the CLR to translate the intermediate code into executable code when a program is run. Thus, any program compiled to MSIL can be run in any environment for which the CLR is implemented. This is part of how the .NET Framework achieves portability.

Microsoft Intermediate Language is turned into executable code by using a JIT compiler. “JIT” stands for “Just-In-Time.” The process works like this: When a .NET program is executed, the CLR activates the JIT compiler. The JIT compiler converts MSIL into native code on a demand basis as each part of your program is needed. Thus, your C# program actually executes as native code even though it is initially compiled into MSIL. This means that your program runs nearly as fast as it would if it had been compiled to native code in the first place, but it gains the portability benefits of MSIL.

In addition to MSIL, one other thing is output when you compile a C# program: metadata. Metadata describes the data used by your program and enables your code to interact with other code. The metadata is contained in the same file as the MSIL.

Using csc.exe, the C# Command-Line Compiler

Although the Visual Studio IDE is what you will probably be using for your commercial projects, the C# command-line compiler is the easiest way to compile and run most of the sample programs shown in this book. To create and run programs using the C# commandline compiler, you will follow these three steps:

1. Enter the program using a text editor.2. Compile the program.3. Run the program.

Compiling the Program

To compile the program, execute the C# compiler, csc.exe, specifying the name of the source file on the command line, as shown here:

C:\>csc Example.cs

Roll No: - 2107217

The csc compiler creates a file called Example.exe that contains the MSIL version of the program. Although MSIL is not executable code, it is still contained in an exe file. The Common Language Runtime automatically invokes the JIT compiler when you attempt to execute Example.exe. Be aware, however, that if you try to execute Example.exe (or any other exe file that contains MSIL) on a computer for which the .NET Framework is not installed, the program will not execute because the CLR will be missing.

Running the Program

To actually run the program, just type its name on the command line, as shown here:

C:\>Example

When the program is run, the following output is displayed:

A simple C# program.

Using the Visual Studio IDE

To edit, compile, and run a C# program using Visual Studio 2005, follow these steps.

1. Create a new, empty C# project by selecting File | New | Project. Next, select Visual C#, and then Console Application, as shown here:

Then, change the name to Project1 and press OK.

2. Once the project is created, the Visual Studio IDE will look like this:

3. Notice that a new window called Program.cs was created. This contains an empty template for a C# console program. This file is created automatically by Visual Studio 2005 and contains the skeleton to a C# program. However, this skeleton is more complicated than it needs to be for our purposes, so delete all of the lines in this window. After doing so, the Program.cs window will be blank, and look like this:

4. Next, enter the example program into the Program.cs window, and then save the file using the name Example.cs. When done, your screen will look like this:

5. Compile the program by selecting Build Solution from the Build menu.6. Run the program by selecting Start Without Debugging from the Debug menu. When you

run the program, you will see the window shown here.

SQL SERVER:

SQL Server is an SQL-compliant RDBMS. SQL-compliant means it use the ANSI

(American National Standard Institute) version of Structured Query Language or ‘SQL’.

Structured Query Language is a command that allow us to modify or retrieve information

from the database.

Client server means that SQL Server is designed to store data in the central location (the

server) and deliver it on demand to numerous other locations (the client). SQL Server is

also a Relational Database Management System (RDBMS).

FEATURES OF SQL SERVER 2005:

Feature Description

Database Mirroring

Extend log shipping capabilities with the database mirroring solution. You will be able to use database mirroring to enhance availability of your SQL Server systems by setting up automatic failover to a standby server.

Online Restore With SQL Server 2005, database administrators are able to perform a restore operation while an instance of SQL Server is running. Online restore improves the availability of SQL Server because only the data being restored is unavailable; the rest of the database remains online and available.

Online Indexing Operations

The online index option allows concurrent modifications (updates, deletes, and inserts) to the underlying table or clustered index data and any associated indexes during index data definition language (DDL) execution. For example, while a clustered index is being rebuilt, you can continue to make updates to the underlying data and perform queries against the data.

Fast Recovery A new faster recovery option improves availability of SQL Server databases. Administrators can reconnect to a recovering database after the transaction log has been rolled forward.

Roll No: - 2107217Standards-based Information Access

Any object, data source, or business intelligence component can be exposed using standards-based protocols such as SOAP and HTTP—eliminating the need for a middle-tier listener, such as IIS, to access a Web services interface that is exposed by SQL Server 2005.

SQL Server Management Studio

SQL Server 2005 includes SQL Server Management Studio, a new integrated suite of management tools with the functionality to develop, deploy, and troubleshoot SQL Server databases, as well as enhancements to previous functionality.

Dedicated Administrator Connection

SQL Server 2005 provides a dedicated administrator connection that administrators can use to access a running server even if the server is locked or otherwise unavailable. This capability enables administrators to troubleshoot problems on a server by executing diagnostic functions or Transact-SQL statements.

Snapshot Isolation Snapshot Isolation (SI) level is provided at the database level. With SI, users can access the last committed row using a transitionally consistent view of the database. This capability provides greater scalability.

Data Partitioning Data partitioning is enhanced with native table and index partitioning that enables efficient manageability of large tables and indexes.

Replication Enhancements

For distributed databases, SQL Server 2005 provides comprehensive schema change (DDL) replication, next-generation monitoring capabilities, built in replication from Oracle to SQL Server, merge replication over https, and significant merge replication scalability and performance improvements. Additionally, the peer-to-peer transactional replication feature improves support for data scale out using replication.

OTHER COMPARABLE TECHNOLOGY

Java is a programming language that can run on many different computers including mobile

phones. It was originally developed by Sun Microsystems and released in 1995. There are small

Java programs, called Applets. They often run inside web browsers. The language derives much

of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java

applications are typically compiled to bytecode (class file) that can run on any Java Virtual

Machine (JVM) regardless of computer architecture.

The original and reference implementation Java compilers, virtual machines, and class libraries

were developed by Sun from 1995. As of May 2007, in compliance with the specifications of the

Java Community Process, Sun relicensed most of their Java technologies under the GNU General

Public License. Others have also developed alternative implementations of these Sun

technologies, such as the GNU Compiler for Java and GNU Classpath.

HMAIL

Hmail is simply a Desktop Application created under window application of .Net framework by applying programming language C#.In this,we can send out text messages from one PC to another PC, we need not to access the Internet. It is based on the Client/Server Application. It describes the relationship between two computer programs in which one program, the client, makes a service request from another program, the server, which fulfills the request.

MAIL SERVER :-

The term Mail Server is also loosely used to mean a computer acting as an MTA(message transfer agent) by running the appropriate software. . If we are sending messages using mail server program, Messages will first be sent from client to mail server for delivery and then sent to recipient.Similar in case of recieving, Messages will be sent from mail server to client(reciever).

An MTA receives mail from a mail user agent (MUA). The transmission details are specified by the our costomize protocol(TTP).The MTA works behind the scenes, while the user usually interacts with the MUA. So MTA is usually coupled with some means for mail clients to gain access to stored

MAIL CLIENT :-

An mail client, mail reader, or more formally mail user agent (MUA), is a computer program used to manage messages.Specifically, the term Mail Client may refer to any agent acting as  client toward an mail server, regardless of it being a mail user agent, a relaying server, or a human typing on a terminal. In addition,it is provided the message management, composition, and reception functionality is sometimes considered an Mail client. Like most client programs, an MUA is only active when a user runs it.Unless the MUA has access to the server's disk, messages are stored on a Server database and the MUA has to request them on behalf of the user.

Security:-

In this section user has to fill one question and it’s answer. Tips of Picking a good security question and answer:-

Choose a question only you know the answer to - make sure the question isn't associated with your password.

Pick a question that can't be answered through research (for example, your birth date, your first or last name, your social security number, your phone number etc.).

Make sure your answer is memorable, but not easy to guess. Use an answer that is a complete sentence for even more security.

This security section is used in future if the given user forgets his password.

Roll No: - 2107217 Inbox user control :-

Mainly inbox is the rest room of mails where one user can have the information about the mails which is send by the existing users on the HMail to that particular user. It’s include the information about:-

1. From 2. Date 3. Subject 4. Body

We also have the options of replying and forwarding the mails, which is conducting by the buttons reply and forward which is shown in the below snapshot of inbox user control.

Now if user Sample wants to reply the answer of the given mail then he/she has to select one row and then has to press reply button by this Send Mail user control will appears on the Parent Form as shown in the Send Mail user control figure. By the help of forward button user can send the particular mail to the other by selecting one row of the table.

At this place we can check mails send by the other usersE.g.:- Sample user has one mail from the qwerty on oct/18/2009

Roll No: - 2107217 Send Mail User Control :-

Sending the mail is the purpose of transferring the information from one user to the other user.And it is the secure way of transferring the information because only that particular user can receive it and read it. For sending the mail we require userid of the user to whom the mail is to be sending. Here in this Send Mail User Control one user can send the mails to the other users. For sending the mail, user has to click the send button. And this mail will be send by the customize protocol TTP.

Roll No: - 2107217This feature allows you to edit your mail, compose your message, indicate 'from', 'reply', mail addresses etc.

This feature is used to make the mail appear as if it were coming from some other mail address than that indicated in your personal account, have replies routed to the proper departments and attach other information which people can then comment on in your survey.

Write the subject for your e-mail in the 'Subject' field. The e-mail subject should be as interesting and powerful as possible in order to ensure your e-mail is opened. It is the first thing we read. Make sure it is clear and state the purpose of your survey, report, reminder or alert mail. Note: make sure "Subject" field does not contain brakes. It is not recommended to copy/paste "Subject" from external sources. These actions may corrupt your Invitation mail.

After Clicking on the send button if the given user exists then that mail is send to that user and the message box will appeared which is shown in the next figure 1.

Generally we have sent mail box for the record of mails which we send to others through one particular user id. And we also have the record of their respective time of sending the mail.This user control shows the record of mails which was sent to the other users by the given user.We have one button of delete to delete the mails present in this. This user control has one table which have four columns:-

1. To(to whom the mail was sent)2. Date(time at which the mail was sent)3. Subject(main subject of the mail)4. Body(main information which was sent)

This is the mail which we send above in the report to user qwerty

Contact is like database where we store the contacts. Each contact entry usually consists of a few standard fields (for example: first name, last name, company name, address, telephone number, mail address, fax number, mobile phone number). Most such systems store the details in alphabetical order of people's names, although in paper-based address books entries can easily end up out of order as the owner inserts details of more individuals or as people move.

This the form where user can add its contacts along with the mail id and home address. In this we have fields like:

In notes we can write about the birth date and other important Information related to that person

This fields are the required fields. That’s why we use here the symbol ‘*’

How does user add people to its Contact list?

1. Click Add Contacts along the left side of HMail Parent form.

2. New form is appeared.3. Enter your contact's information in the appropriate

fields.4. Click Save and Close to add your contact.5. For ignoring that click close.

When user clicks the Save and Close button the message box will appears if contact is added successfully in the data base as shown in the figure below.

Address Book User Control:-

An address book is a book or a database used for storing entries called contacts. Each Address Book entry usually consists of a few standard fields (for example: first name, last name, company name, address, telephone number, e-mail address, fax number, mobile phone number). Most such systems store the details in alphabetical order of people's names, although in paper-based address books entries can easily end up out of order as the owner inserts details of more individuals or as people move.

Roll No: - 2107217PROTOCOL:-

In computing, a protocol is a set of rules which is used by computers to communicate with each other across a network. A protocol is a convention or standard that controls or enables the connection, communication, and data transfer between computing endpoints. In its simplest form, a protocol can be defined as the rules governing the syntax, semantics, and synchronization of communication. Protocols may be implemented by hardware, software, or a combination of the two.

Properties Of Protocol:-

While protocols can vary greatly in purpose and sophistication, most specify one or more of the following properties:-

Detection of the underlying physical connection (wired or wireless), or the existence of the other endpoint or node.

Handshaking. Negotiation of various connection characteristics. How to start and end a message. Procedures on formatting a message. What to do with corrupted or improperly formatted messages. How to detect unexpected loss of the connection, and what to do next. Termination of the session and/or connection.

Introduction to TTP:-

TTP stands for Text Transfer Protocol. Text transfer protocol is a set of rules to transfer, sending and receiving the text messages. In this, we are only concern with the text messages. Transfer of mails is done with the help of Mail Helper. Mail Helper is a means of communication between the Mail client and Mail Server. In Mail helper, mainly two processes are taken. First is of sending the messages and second is of receiving the messages. For sending of mails, the sent message is joined, converting into bytes and write in network stream. Now the question arises how the joining of messages take place. Each messages are joined by the field separator and terminated with message terminator. As we made our own customized protocol, We use certain set of rules. Here the Field separator is null character(‘/0’) and the message terminator is ctrl-z whose ASCII value is 26.For receiving the message, first we split the message and then send to information to client. This splitting of messages is done by using Dynamic array,ie the list of strings. We add the each part of dynamic array and converted into new array by using the function .ToArray( ). In this way this protocol works.

DATABASE DESIGN WITH E-R DIAGRAM

In software engineering, an Entity-Relationship Model (E-R Model) is an abstract and conceptual representation of data. Entity-relationship modeling is a database modeling method, used to produce a type of conceptual schema or semantic data model of a system, often a relational database, and its requirements in a top-down fashion.

Diagrams created using this process are called entity-relationship diagrams, or ER diagrams or ERDs for short. An entity may be defined as a thing which is recognized as being capable of an independent existence and which can be uniquely identified. An entity is an abstraction from the complexities of some domain. When we speak of an entity we normally speak of some aspect of the real world which can be distinguished from other aspects of the real world. An entity-relationship (ER) diagram is a specialized graphic that illustrates the interrelationships between entities in a database. ER diagrams often use symbols to represent three different types of information. Boxes are commonly used to represent entities. Diamonds are normally used to represent relationships and ovals are used to represent attributes.

The first stage of information system design uses these models during the requirements analysis to describe information needs or the type of information that is to be stored in a database. The data modeling technique can be used to describe any ontology (i.e. an overview and classifications of used terms and their relationships) for a certain area of interest. In the case of the design of an information system that is based on a database, the conceptual data model is, at a later stage (usually called logical design), mapped to a logical data model, such as the relational model; this in turn is mapped to a physical model during physical design.Eg.

Data Flow Diagrams

DFD’s have the purpose of clarifying system requirements and identifying major transformations that will become programs in system design. A DFD is also known as “Bubble chart” has the purpose of clarifying system requirements and identifying major transformations that will become programs in system design. So it’s a starting point of the design phase that functionality decomposes the requirements specifications down lines. The bubbles represent data transformation and lines represent data flows in the system. DFD SYMBOLS:-

In DFD there are four symbols:

A CIRCLE or a BUBBLE represents the process that transforms incoming data flow(s) into outgoing data flow(s).

An OPEN RECTANGLE is a data store-data at rest, or a temporary repository of data.

A SQUARE defines the originator or the destination of the system data. An ARROW identifies the data flows in motion. It’s a pipeline thru which

information flows.
