A Program that illustrates basics of Operator overloading in C#

I developed this class in C# to illustrate the basics of Operator overloading and Typecasting This sample also contains a use of the ToString method. This example is divided into three parts:-

 

Program.cs
//************************************************************************************
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Operator_Overloading
{
    class Program
    {
        static void Main(string[] args)
        {
            Currency c1 = new Currency(-12, 234);
            Currency c2 = new Currency(12, 234);
            Currency sum = c1 + c2;
            Console.WriteLine(sum );
            if (c1 < c2)
                Console.WriteLine(c1);
            else
                Console.WriteLine(c2);
            double d = c1;
            Console.WriteLine(d);
            int n =(int) c1;
            Console.WriteLine(n);
            Console.WriteLine(c1["rupees"]);
            Console.ReadKey();
        }
    }
}

Implementing Binary Trees in C

This is a program that I had in my mind for almost 3 years before I actually implemented it.
This program uses RECURSION to implement most of the algorithms here.
The DrawTree function is the one that draws the tree. It's based on the simple concept that at the Root Level we have just one node, two at the next, 4 at the next, in general 2 to the power h at level h.

Getting Global Weather Via Web Services using ASP.NET

Windows Communication Foundation is Microsoft's new technology for implementing Remote Procedure Calls. It is intended to integrate all the previous variations like Messaging,Message Queuing, Remoting, and Web Services. Web Services use the HTTP port, and use an XML standard SOAP(Simple Object Transfer Protocol) for remote access. Web Services are described through the WSDL(Web Services Description Language) There are many free Web Services available on the Internet.
For this application I used the following URL http://www.webservicex.net/globalweather.asmx
Here is the Complete Application :---

1) Start a new ASP.NET Application.
2) Add A Service reference to the above URL

Two String functions in C using Pointers.

Getting back to what I love the most C Programming using Pointers.

StringPointers.c


#include<stdio.h>
#include<conio.h>
int strlen(char s[]);
void strcat(char src1[],char src2[],char dest[]);
void main()
{
int l;
char *str;
char s1[50],s2[50],s3[100];
clrscr();
gets(str);
l=strlen("Apple");
printf("\n%d",l);
l=strlen(str);
printf("\n%d",l);
printf("\nEnter s1 = ");
gets(s1);
printf("\nEnter s2 = ");
gets(s2);
strcat(s1,s2,s3);
printf("\n%s",s3);
getch();
}
void strcat(char src1[],char src2[],char dest[])
{
while((*dest++=*src1++)!='\0')
;
dest--;
while((*dest++=*src2++)!='\0')
;
}
int strlen(char s[])
{
int n=0;
while(*s++!='\0')
n++;
return(n);
}

To be continued . . .

Creating and entering a new Bean into Net Beans

This article will create and enter a TimerLabel into a Palette inside NetBeans from where we can use it in any Project. The Timer label will simply display the current date and time.

Starting the Project: Create a File called TimerLabel.java with the following Contents.

TimerLabel.java

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */


package timerbeansproject;


import java.util.Date;
import javax.swing.JLabel;


/**
 *
 * @author Champak */
public class TimerLabel extends JLabel {


    public TimerLabel()
    {
        TimerThread t=new TimerThread();
        t.start();
    }
    private class TimerThread extends Thread
    {
        @Override
        public void run()
        {
            while(true)
            {
                try
                {
Date d=new Date();
TimerLabel.this.setText("" + d);
Thread.sleep(1000);
                }
                catch(Exception ex)
                {
                    System.out.println(ex);
                }
            }
        }
    }


}

TimerFrame.java

/**

public class TimerFrame extends javax.swing.JFrame {


    /** Creates new form TimerFrame */
    public TimerFrame() {
        initComponents();

    /** This method is called from within the constructor to

        timerLabel1 = new timerbeansproject.TimerLabel();


        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);


        javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
        getContentPane().setLayout(layout);
        layout.setHorizontalGroup(
            layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
            .addGroup(layout.createSequentialGroup()

                .addContainerGap(150, Short.MAX_VALUE))
        );
        layout.setVerticalGroup(

            .addGroup(layout.createSequentialGroup()
                .addContainerGap()
                .addComponent(timerLabel1, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
                .addContainerGap(275, Short.MAX_VALUE))
        );


        pack();
    }// </editor-fold>


    /**
    * @param args the command line arguments
    */
    public static void main(String args[]) {
        java.awt.EventQueue.invokeLater(new Runnable() {

}

The series of Steps

1. Starting the New Project
   

2. Building the Project.

 

3.Opening the Palette.

 

4.The Palette Manager

 

5.Selecting the Project containing the New Bean

6.Choosing the Component.

 

7.Adding the Timer Label to a JFrame
