Creating Symbolic Link (Symlink) in Windows 7

Hi friends,

In Linux, it is easy to create symbolic link (symlink) with "ln" command.
But what about in windows?

I found one GUI and command for creating the symbolic links in windows.

Pre-requisites

1. Visual Studio 2005 redistributable
2. Link Shell Extension
3. Download the above executables from here based on OS and system architecture
4. For Windows 7 64-bit, I have downloaded the following highlighted in black box

Procedure

• Install the Visual Studio 2005 redistributable
• Install Link Shell Extension
• You should be able to see an option in context menu
• Select the file/folder
• Right click and select the option "Pick Link Source"

• Now, the file is been picked
• Navigate to go the destination folder where you want to create the symbolic link
• Right click on the empty space of the folder
• Select Drop As and select "Hardlink or Symbolic Link" based on your requirement

• You should be able to see the file type as .symlink

Creating basic Graphical User Interface (GUI) application in java with Screenshots

Hi all,

One of my friend asked me, how to create a basic java GUI application which can run on desktop?

A small java gui desktop application, which is having a button and when user click on it, it will show the status of the application.

Source code:

import javax.swing.JFrame;
import javax.swing.JButton;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
import javax.swing.JOptionPane;

public class PSRSampleGUI
public static void main(String[] args) {
       
        // Creating a frame
        JFrame frame_name = new JFrame("PSR");
      
        //Setting the layout to view the content
        frame_name.setLayout(new FlowLayout());
      
        // Sample lable option
        JLabel label_name = new JLabel("Click Start button");
      
        // Creating a button
        JButton button_name = new JButton("Start");
      
        // Adding button to frame
        frame_name.add(label_name);
        frame_name.add(button_name);
      
        // Adding button functionality
        button_name.addActionListener(new ActionListener()
        {
            @Override
            public void actionPerformed(ActionEvent ae)
            {
                JOptionPane.showMessageDialog(null, "Started", "App Status", JOptionPane.INFORMATION_MESSAGE);
                // Call the method here ( the implemented method)
            }
        });
      
        // Displaying the frame in the center of the screen window
        Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
        Dimension windowSize = frame_name.getSize();
        int windowX = Math.max(0, (screenSize.width  - windowSize.width ) / 2);
        int windowY = Math.max(0, (screenSize.height - windowSize.height) / 2);
        frame_name.setLocation(windowX,windowY);
      
        // Displaying the Frame with packing all the contents properly
        frame_name.setVisible(true);
        frame_name.pack();
    } // main method ends here
} // class ends here

Screenshots:

• By Running the application, you will get the following window in the center of your screen.

• After clicking on "Start" button, you will get the following window
