Unofficial Way2Sms API Using JAVA To Send Free SMS

This is a way to send free sms from our computer through Way2sms, which allows to send free sms.
Using this code one can send sms to multiple phone numbers like shown in the screen shot

For that you need to have the following


1) You have to register at Way2SMS and Obtain a User Name and Password.

2)You have to find the ACTION value.

*In-order to  find the action value first install 'fire bug' to your Firefox.
*Then login to your way2sms account.
*Open Firebug from tools->Firebug->open firebug.
*In the search field of firebug type 'action' and click next until you find something like
<input id="Action" type="hidden" value="sa65sdf656fdfd" name="Action">

*Now the value 'sa65sdf656fdfd' is your ACTION value.


Now everything set up. Download the source


JAVA PROGRAM FOR SENDING SMS THROUGH WAY2SMS

Now open the source and edit the following fields in main()
* USERNAME : Your way2sms username
*PASSWORD : Your way2sms password
*ACTION : The ACTION value we found out
*Also uncomment the proxy support if needed.

Now compile the code

          javac Way2SMS.java

Run the code

java Way2SMS phone no1 no2 ....  message your message here!



Example :
java Way2SMS phone 1234567890 0987654321 message Where where you yesterady?





Note: Few weeks ago one of my friend Srijidh asked about sending sms from our desktop. But at that time we were having university exams. Today I remembered his query and decided to code. I wrote this code after referring several python codes from github and that found on google search.

Note2: The ACTION value is so important that if you have omitted the program will not  give the desired result. In future I will add feature to automatically fetch that ACTION field for you.

Simple Command Line Cricket Score Viewer.

This is a command line program for displaying cricket scores.


This https://github.com/semk/cricinfo python library  found in the blog http://foobarnbaz.com/lab/ made me think about creating a similar one in Java. I created a simple library class and its implementation for this purpose. Let me show you some screen shots
It can show all the scheduled matches for that day,

  Or it can list already started matches,

 

 Or it can show match of your favorite team,

This program works based on the http://www.espncricinfo.com/ site's rss feed.


Usage
--------- 
SOURCE:COMMAND LINE CRICKET SCORE VIEWER


Download the two java sources files to a directory, FOLDER


now goto terminal type,


cd FOLDER

javac *.java

java CricDisplay

note: edit CricDisplay.java file and uncomment the proxy support if needed

I am looking forward to add more features like displaying match schedules, match status etc...

A Simple Querry Analyser

This is a simple program that can be used in any platform form that supports java to analyse Database querries.......
In windows it can work with any databases provided it is registered through ODBC.In all other platforms it support only mysql.......

The default selection is 'linuxmysql' server do not change that if you are connecting to mysql database.If you want to connect to any other databases in windows follow the instructions in http://www.mundayweb.com/progs/jdbc-odbc-tut.php.

So if you want to add sql jdbc driver goto Datasources-->Add->give a suitable name for the driver(which is later supplied as server to the program)-->select a server and complete the procedures.


So you are done with the ODBC-JDBC driver settings.

The program consists of three source files.File name is given in the top of each source file.Put the three source files togein a folder named  testproj.

One more thing, you need to download a java-mysql connector package and either link it with the project or point the environment variable CLASSPATH to the folder containing the package.

Fun With ROBOT class...

java.awt.Robot is a class which can make the mouse move,trigger key press,trigger key release,take screen capture etc..

I would like to show a simple example with Robot class.....................

import java.awt.AWTException;
import java.awt.FlowLayout;
import java.awt.GraphicsEnvironment;
import java.awt.Robot;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;


public class Main extends JFrame implements MouseListener{

/**
Mouse listener interface is implemented to get mouse events like mouse clicked,pressed,released,entered and exited events.
*/
Robot R;
JButton intel;
JButton notintel;
JLabel lab;
JPanel p;
Main()
{
try {
R = new Robot(GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice());
/*
constructor of robot class takes a graphic device as argument.We supply the default screen device
*/
} catch (AWTException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
}
intel=new JButton("INTELLIGENT");
notintel=new JButton("NOT INTELLIGENT");
lab=new JLabel("SELECT THE OPTION WHICH SUIT YOU");
p=new JPanel(new FlowLayout());
//flow layout is applied to the panel....
this.add(p);
p.add(lab);
p.add(intel);
p.add(notintel);
intel.addMouseListener(this);
//mouse listener registered with buttons
notintel.addMouseListener(this);
this.setAlwaysOnTop(true);
this.setUndecorated(true);//to avoid close bar
this.setSize(300,75);
this.setVisible(true);//to display the JFrame
this.setLocation(500, 500);
}
public static void main(String[] args) {
// TODO code application logic here
new Main();
}

public void mouseClicked(MouseEvent e) {
JButton b=(JButton) e.getSource();
if(b.getText().equals("NOT INTELLIGENT")) {
System.exit(0);
}

}

public void mousePressed(MouseEvent e) {

}

public void mouseReleased(MouseEvent e) {

}

public void mouseEntered(MouseEvent e) {

JButton b=(JButton) e.getSource();
if(b.getText().equals("INTELLIGENT")) {
R.mouseMove(400,400);//mouse is moved using object of robot class
}
}

public void mouseExited(MouseEvent e) {

}

Some Experiments With JAVA For Beginners....

I am Using NETBEANS IDE 6.8 for developing java programs. I am not a professional Java programmer, but just a beginner. So i thought sharing some programs with others will be fun and also their responses will be a great benefit..

First I am going to develop an application which will float on your desktop.

For that Create a new project in the netbeans ide. And then add a new package named "resource" drag and drop the one image(in my case its bella.jpg) to this package...

Then code the Main.java ........

/*import necessary classes*/

import java.awt.Dimension;

import java.awt.Graphics;

import java.awt.Image;

import java.awt.Toolkit;

import javax.swing.ImageIcon;

import javax.swing.JPanel;

import javax.swing.JWindow

public class Main extends JWindow { /*this JWindow is floating on the screen*/

Image ico; /*this holds the image that we want to draw on the screen*/

int width=200; int height=300; /*specify the height and width of the application*/

Dimension d;

Main()

{

ico=new ImageIcon(this.getClass().getResource("/resource/bella.jpg")).getImage();

/* The image is retrieved from the package using this.getClass().getResource(String filename)

so that the application become portable. */

this.setSize(width, height); /*height and width of the JWindow is set.*/

this.setVisible(true);

d= Toolkit.getDefaultToolkit().getScreenSize(); /*a dimension consist of a width & height

Toolkit.getDefaultToolkit().getScreenSize() gives the current screen size*/

d.height=d.height-height; /*to get bottom limit of the screen*/

d.width=d.width-width; /*to get right limit of the screen*/

}

public void paint(Graphics g) /*this paint method is invoked automatically*/

{

if(g!=null)

g.drawImage(ico, 0, 0, width, height,null);

/* Above code draws image ico at (0,0) and scale the image to the width and height specified*/

else

System.out.println("null");

}

public static void main(String[] args) throws InterruptedException {

new Main().flow(0,0,3,3);

/*Initial positon of the window when execution started and the increment factor of both x and

y. It can be chaned to experiment your self */

}

void flow(int x,int y,int incx,int incy) throws InterruptedException {

while(true)

{

x=x+incx; y=y+incy; /*new x and y position for window is calculated*/

this.setLocation(x, y); /*change the location of the window to the new location*/

Thread.sleep(30); /*put a small delay between two adjacent relocation of window

remember 'main' it self starts as a thread. */

if(x<0)>

{

incx=-incx;//reverse the increment value so that window goes to opposite x direction

}

else if(x>d.width)

{

incx=-incx;//reverse the increment value so that window goes to opposite x direction

}

if(y<0)

{

incy=-incy;//reverse the increment value so that window goes to opposite y direction

}

if(y>d.height)

{

incy=-incy;//reverse the increment value so that window goes to opposite y direction

}

}

}

}
