Ex No:1 MATRIX TRANSPOSE USING HTML AND JAVASCRIPT

AIM:

To perform matrix transpose using HTML and JavaScript by dynamically getting the input depending on the order of the matrix specified by the user.

ALGORITHM:

1. Design the user interface in HTML2. Get the number of rows and columns from the user3. The rows and columns are send to the Asp page4. The ASP page generates the required number of text boxes dynamically based on the

number of rows and columns.5. The transformation of the matrix is performed6. The result is displayed in matrix form.

Ex No:2 USER REGISTRATION PAGE VALIDATION USING VBSCRIPT AND JAVASCRIPT

AIM:

To perform user validation for the inputs given through HTML using VBScript and JavaScript.

ALGORITHM:

1. Design the html form to get the inputs from the user.2. Specify the scripting language as either vbscript or javascript3. Check if the values are entered in the input boxes by retrieving the data using

document.formname.textboxname4. If the data is not entered alert the user with the message that the data is not entered.

AIM:

To establish database connection using ASP, JSP and PHP

DATABASECONNECTION USING ASP:

ALGORITHM:

1. Design the user interface where the necessary controls are added.2. Save the file as .asp .3. Action to be performed is written in another file and saved as .asp files.4. The files are saved in Programfiles->Inetpub->wwwroot.5. Database connectivity is established using the following code

Set DB = Server.CreateObject ("adodb.Connection")DB.Open ("PROVIDER=Microsoft.Jet.OLEDB.4.0;DATA SOURCE=C:\Inetpub\wwwroot\studreg.mdb")

6. Coding is written for operations like Insertion,Deletion,UPdation.7. Program is run and executed using the IIS server –http://localhost/(filename).asp

EX. No:5 ADROTATOR AND CONTENT ROTATOR

AIM: To implement Ad-rotator and content-rotator using asp.

ALGORITHM: 1. The ASP AdRotator component creates an AdRotator object that displays a different

image each time a user enters or refreshes a page.2. The only difference between ad-rotator and content rotator is that, in content rotator only

content is displayed where as in ad-rotator both images and content are displayed.3. Initially the images and the content to be displayed are collected and the required html code is

written with the exact path, where those pictures are stored.4. The adrotator is given a name to access the page.5. The pictures are separately stored in another file.

Ex No:11 SHOPPING CART USING JAVA THREADS

AIM:

To implement shopping cart using java threads.

ALGORITHM:

1. Start.2. Import the necessary packages to create an applet.3. Design the user interface using the required controls like labels, text boxes, check boxes and buttons and code the necessary events for the buttons. 4. Compile the applet and run the applet by invoking the appletviewer command in the command prompt.5. When a number has to be given as an input to perform some operation the corresponding button is clicked and the respective actionPerformed() method is invoked.6. On pressing the “=” button the result is displayed in the text box.7. Stop.

Ex No:12 SOCKET PROGRAMMING

AIM:

To implement socket programming using java.

ALGORITHM:

1. In server side, create a server socket.2. Server socket is ready to accept the client request.3. Server will get the message from client and read it using the class DataInputStream.4. In client side, client will get the server IP address.5. Then it will create the socket.6. Client will send the message through DataOutputStream class.7. In this way both server and client will communicate.

CODING:

SOURCE:

import java.io.*;import java.net.*;public class Provider{

ServerSocket providerSocket;Socket connection = null;ObjectOutputStream out;ObjectInputStream in;String message;Provider(){}void run(){

try{//1. creating a server socketproviderSocket = new ServerSocket(2004, 10);//2. Wait for connectionSystem.out.println("Waiting for connection");connection = providerSocket.accept();System.out.println("Connection received from " +

connection.getInetAddress().getHostName());//3. get Input and Output streamsout = new ObjectOutputStream(connection.getOutputStream());out.flush();in = new ObjectInputStream(connection.getInputStream());sendMessage("Connection successful");//4. The two parts communicate via the input and output streamsdo{

try{message = (String)in.readObject();

System.out.println("client>" + message);if (message.equals("bye"))

sendMessage("bye");}catch(ClassNotFoundException classnot){

System.err.println("Data received in unknown format");}

}catch(IOException ioException){
