JavaFX : How to implement Drag and Drop
Drag and drop allows data transfer between various components in your javafx application. It allows transferring data in between your internal nodes or between two applications.

A drag-and-drop gesture happens as follows: The user click a mouse button on a gesture source, drags the mouse, and releases the mouse button on a gesture target. While dragging the data, the user gets visual feedback, which denotes locations that do not accept the data and, when over a target that accepts the data, gives a hint where to drop the data.

The data is transferred using a dragboard, which has the same interface as a system clipboard but is only used for the drag-and-drop data transfer.Various types of data can be transferred such as text, images, URLs, files, bytes, and strings.

1. Receiving Data From other applications

Receiving data from other applications through drag and drop is very simple in JavaFX. The method setOnDragOver of node allows controlling what happens when something is dragged over the node. For example, as you can see in the top image, I have added a simple ImageView and implemented setOnDragOver to accept when files are dragged over it. Let’s see the code.
```
imageView.setOnDragOver(new EventHandler() {
   public void handle(DragEvent event) {
      if (event.getDragboard().hasFiles()) {
         event.acceptTransferModes(TransferMode.ANY); 
      }
      event.consume();
   }
});
```
In this code, I have added event handler for the image view for Drag Over case. The getDragboard method gives the Dragboard object which contains the files being transferred. The method hasFiles() is invoked to make sure that, the dragged content is a file. This is done to avoid when something other than files are dragged, like string or rich text content.
```
event.acceptTransferModes(TransferMode.ANY);
```
This line makes the component ready to accept the incoming data. As a result, we will get a hand with a plus symbol when dragged over image view.

The last thing we have to do is to accept the files when dropped. The method setOnDragDropped allows to achieve this. In our case we have to do as follows.
```
imageView.setOnDragDropped(new EventHandler&lt;DragEvent&gt;() {
    public void handle(DragEvent event) {
        List&lt;File&gt; files = event.getDragboard().getFiles();
        System.out.println("Got " + files.size() + " files");
        imageView.setImage(new Image(new FileInputStream(files.get(0))));
        
        event.consume();
     }
});
```
In this code, the list of incoming files is taken using event.getDragboard().getFiles() method. So we can send a list of file instead of a single one. From the received files, we have to create an image and set it as the image for the imageview.

So, this is as simple as a drag and drop operation can get. Now let’s see how we can implement drag and drop for two internal nodes.

2. Drag and Drop between two internal components

For making a node ready to be dragged, we can use setOnDragDetected method. This function will be called whenver a drag operation is done on the component. Here, source is a Text variable that contains some text.

When the source is dragged, The Dragboard class from javafx.scene.input.Dragboard is constructed by calling source.startDragAndDrop() method. Transfer modes define the type of transfer that happens between the gesture source and gesture target. Available transfer modes include COPY, MOVE, and LINK.

Inorder to send data from the source an instance of ClipboardContent is used. Since we are sending String data, putString method is used. After setting the content, it is then associated with Dragboard db.

Now source will allow dragging string data. ie, It act as a source.
```
source.setOnDragDetected(new EventHandler&lt;MouseEvent&gt;() {
    public void handle(MouseEvent event) {
        Dragboard db = source.startDragAndDrop(TransferMode.ANY);
        
        ClipboardContent content = new ClipboardContent();
        content.putString(source.getText());
        db.setContent(content);
        
        event.consume();
    }
});
```
Now just like we did in the image view, we need to setup the Text at the destination ready to accept the incoming string. This can be done by using setOnDragOver and setOnDragDropped.

How to make Navigation Drawer (Side Panel) in JavaFX – JavaFX Drawer
Navigation drawer provides an intuitive way to keep main navigation controls of the UI clean. The drawer will only be made visible to the user on certain actions like button click so that we can make use of that space for much more important things yet keeping controls reachable with single click.

Android introduced the material design Navigation bar or side pane or whatever you call, with its Material design goodness. JFoenix library provides JFXDrawer component.

Today, I will be showing how to implement the Navigation drawer on your JavaFX application using JFoenix material design library. If you want some help on setting up the JFoenix material design library, see my post JavaFX Material Design : Setting Up and Making Login Application.

I have made a video to make things more clear. You can watch it right here.

If you are the kind of person who do not like to watch tutorial videos, read from here. I will explain it step by step.

Step 1 : Design Content For Navigation Drawer
At first, you have to create an FXML layout for the Navigation bar itself. This layout can then be inflated to the navigation bar holder later. The above image shows a pretty simple VBox layout that consists of 4 Buttons and one image view. This content can the be loaded to a VBox variable in our code (from the main controller) using the following code

VBox box = FXMLLoader.load(getClass().getResource("SidePanelContent.fxml");

Step 2 : Design The Container (Main) Window
Main window with Hamburger

Now we have the navigation bar content. In this step, you have to design the main application window. The JFXDrawer can be added using scene builder by drag and drop. Once you position the drawer on the space you want, you can set the drawer direction to LEFT, RIGHT, TOP or BOTTOM from the Properties section of Scene Builder.

I have added a JFXHamburger for material design look and feel. I have thouroughly explained how to use JFXHamburger in this video https://www.youtube.com/watch?v=rCnPY9Kj4J0 . If you don’t like to have a Hamburger, you can use a simple button. Add an action listener to your button and add this code.
```
@FXML
//Accessing FXML Element
JFXDrawer drawer;
//Add this in ActionListener
if(drawer.isShown())
drawer.close();
else
drawer.open();
```
The navigation drawer can be made visible by using the open() method. It can be made invisible through the function call close().
Step 3 : Setting the content of Drawer

Now we have two separate components. The Drawer and Main window. We can attach the box loaded in step 1 to our drawer in main window using the following code.
```
drawer.setSidePane(box);
```
Step 4 : There is no 4th step. You are done !

I used to get happier when things get completed sooner that expected. That’s why there is a step 4 🙂

Run the code now. When you click on your button or Hamburger,you should see the navigation drawer like this. If you have some alignment issues for the drawer, increase the value of “Default Drawer Size” from the Scene Builder.
Recently, as part of library management software tutorial, I have created more elaborate tutorial about creating Navigation Drawer. It contains more complex buttons with icons and CSS styling. Watch those tutorial videos from the following link.

How to add JavaFX Charts / Graphs : Tutorial

JavaFX provides a powerful set of Charts/Graphs that can be added very easily to your programs. Frankly, It is even easier than adding a Table in JavaFX. Graphical charts are available in the javafx.scene.chart package.

Bar Chart

This video describes how to add Bar Chart to your JavaFX program.

Bar Chart data can be represented using an XYChart.Series object. All that you have to do is to make a new object and add data to it.

XYChart.Series set1 = new XYChart.Series<>();

Data can be added to this set using the code. Here XYChart.Data() takes two parameters. First one is for the X-Axis(Horizontal) and the second one is for Y-Axis(Vertical).

set1.getData().add(new XYChart.Data("James", 5000)); set1.getData().add(new XYChart.Data("Alice", 10000)); set1.getData().add(new XYChart.Data("Alex", 2000));

Finally, Connect the created series with your JavaFX Bar Chart object using getData().addAll() method.

SalaryChart.getData().addAll(set1);

AddAll() method allows to add more than one series of data to your chart. For example if i have set1,set2 and set3 then i can add all of them by using a comma seperated list.

SalaryChart.getData().addAll(set1,set2,set3);

Pie Chart

JavaFX Pie Chart uses an ObservableList which is very similar to XYSeries.Series we used for Bar Chart. This video explains how to use pie chart.

ObservableList<PieChart.Data> pieChartData = FXCollections.observableArrayList( new PieChart.Data("Cars", 13), new PieChart.Data("Bikes", 25), new PieChart.Data("Buses", 10), new PieChart.Data("Cycles", 22)); pieChart.setData(pieChartData);

Here i have created an ObservableList and added 4 values. The pie chart takes all of these values and allocate a percentage for each one.

For eg, Percentage of cars = 13/(13+25+10+22) = 18.5%

The data then can be associated with the chart using the same code used for Bar chart or using a simple alternative

pieChart.setData(pieChartData);

provided, pieChart is the Pie Chart object and pieChartData is the ObservableList.

Line Chart

Construction of Line Chart in Java is very much similar to Bar Chart. It takes the same XYChart.Series object.

XYChart.Series series = new XYChart.Series(); //Make a new XYChart object //Add Data series.getData().add(new XYChart.Data(“1”, 23)); series.getData().add(new XYChart.Data(“2”, 14)); series.getData().add(new XYChart.Data(“3”, 15));

Finally, associate the data with Line Chart.

LineChart.getData().addAll(series);

Area Chart and Scatter Chart

These two are explained together because, both of these Charts takes same type of data. Yes, the XYChart.Series object. We can use the same example used above.

XYChart.Series series = new XYChart.Series(); //Make a new XYChart object //Add Data series.getData().add(new XYChart.Data(“1”, 23)); series.getData().add(new XYChart.Data(“2”, 14)); series.getData().add(new XYChart.Data(“3”, 15));

Finally, associate the data with both charts.

AreaChart.getData().addAll(series); ScatterChart.getData().addAll(series);

So that’s how we add a chart /Graph to our JavaFX program and i hope you understood these things well enough.

Text Editor in Java with Source Code
Today, I am going to make a Text Editor program using our Java. Yeah, Like notepad. I want to add some basic functionalities like Opening a file, Saving a file and option to change the font size. It will only take less than 100 lines of code to do this (Excluding User Interface).

I started with the toolbar javax.swing.JToolBar and added 4 buttons. Button with simple label logo and text for open,save and font size changing. The display area is simply a JTextArea with monotype font.

Opening a Text File

It is pretty straightforward to use JFileChooser to select a file. When I started thinking about opening a file, I wanted a File Chooser that filter and display only text files.Thanks to FileNameExtensionFilter from javax.swing.filechooser.FileNameExtensionFilter. I am able to display only text files on the JFileChooser using the code
```
FileNameExtensionFilter filter = new FileNameExtensionFilter("TEXT FILES", "txt", "text");
fileOpener.setFileFilter(filter);
```
When the user selects a file and click open, The Scanner from java.util.Scanner is used to read the file.
```
Scanner scn = new Scanner(file);  
String buffer = "";  
while (scn.hasNext()) {  
   buffer += scn.nextLine() + "\n";  
}  
display.setText(buffer);  
```
The “file” is nothing but the file taken from the JFileChooser and the while loop will continue until the end of file. “display” is the name of JTextArea, our display.

Saving a Text File

A global file variable called “currentEditingFile” is maintained to know whether we are working on a new, unsaved data or on an opened file. If “currentEditingFile” is null we have a new uncreated file. So the saving method will look to “currentEditingFile” and if it is null a JFileChooser will be opened to select the location for the new file. After selecting the directory, file name is taken from JOptionPane input dialog.

The file is then written onto the file Using PrintWriter from java.io.PrintWriter.

Changing Font Size

A global variable with default font size as 14 is maintained and increased or decreased depending upon the button pressed.
```
display.setFont(new java.awt.Font("Monospaced", 0, ++fontSize));  //Increase font size
display.setFont(new java.awt.Font("Monospaced", 0, --fontSize)); //Decrease font size
```
Extra Works

It is not acceptable to exit the program without any notice when the user clicks on the Close button. In order to add a save confirmation, i made an override on the Window Closing operating and added a confirmation message. It is done from the constructor itself
```
this.addWindowListener(new WindowAdapter() {  
   @Override  
   public void windowClosing(WindowEvent e) {  
	 super.windowClosing(e); //To change body of generated methods, choose Tools | Templates.  
	 int ans = JOptionPane.showConfirmDialog(rootPane, "Save Changes ?", "Confirm", JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE);  
	 if (ans == JOptionPane.YES_OPTION) {  
	   //Write Changes 
	   saveChanges();  
	 }  
   }  
});
```
So that’s it. Download the program / source code from below buttons. If this was helpful please like me on facebook and keep visiting for more cool programs and sources.

Find Perfect Domain Name with Domain Suggestion Tools
We all like to have a short yet meaningful domain names for our website or blog. But searching for available domains on GoDaddy or Big Rock is very time consuming and frustrating. In my case, I wanted a simple domain name related to programming. I searched and searched. Finally bought www.genuinecoder.comfrom GoDaddy. The truth is, I named this blog as Genuine Coder after purchasing the domain name.

So that’s not your case, right? Well, there are a number of ways to find out available domain names. Let’s see how we can find a perfect domain name for you.

Lean Domain Search

Lean domain search asks to enter a word that you want your domain name to include. I have used “programming” and got 3,875 available domains. Lean domain search provides options to sort result according to popularity, length or alphabetical order. Moreover, it searches on twitter to find out whether “@yourdomain” is available on twitter.
- When sorted based on popularity, I got “ProgrammingMarket.com” as the first result
- When sorted according to length of the domain, I got “ExProgramming.com”.
- Sorting based on alphabetical order gave me “AbacusProgramming.com”
Lean domain search also provides Search Term Filter that helps to filter the result based on domain names starting with search term or ending with search term.

Domains Bot

Domains bot work like Lean domain search. Once you enter a keyword, you will get list of available domains. You can choose whether you want particular TLD (Top Level Domain) like .com, .org etc. It is also possible to choose the words from English, Deutsch, Español, Italiano, Français and Dutch.

NameMesh

Name Mesh is also a good choice. Simply enter in your keywords and results will be sorted into eight categories of results, including Common, New, Short, Extra, Similar, SEO, Fun and Mix. You can refine your result by limiting the maximum characters or showing only ones that available with particular registrar like GoDaddy or BlueHost.

Domainr

Domainr is a simple tool to find available domains. It has less options compared to above ones. When you search for a specific keyword in domainr, you will get a list of .com, .org, .co.in etc variations. Unlike above tools, it does not provide any added keywords as prefix and suffix.

I searched for eye and got eye.com, eye.net etc. as taken and eye.org for sale.

Conclusion

It is better to do a thorough research before buying a domain. Because After setting one domain for your website/blog, it is hard to change since all the search engine entries and back-links will be lost. Moreover, you will loose your precious Alexa ranking too.

All of these tools are very helpful. Yet, I prefer LeanDomainSearch and NameMesh since they have a lot of search refining options.

Directory / Folder Indexing Program Using Java

I thought it will be cool if I can make a program that scans some pen drive or hard disk connected to my PC in order find out how many images,videos or documents are there. In simple terms, a directory or folder/file indexing program. Thanks to java again.

Directory Indexer Main Window

Directory indexer uses the FILE class from java.io package. An object of FILE can store both files and directories. The parent or Root directory, from where we start indexing is read from the user using normal JTextField. Then a function called processDirectory() is called with argument as the given input text.

The function, processDirectory() then create a new File with argument as given path. Then the list of files and directories present inside the directory are taken as a file array using listFiles() method from File class. If you are interested in finding more about file listing, read How tocreate a file explorer in java.

 File[] listFiles = fl.listFiles();

After getting the list of contents in the given directory, a for loop is applied which will go through all the available contents (objects of File class). As we said earlier, it can be either a file or a directory. If it is a file, then we check its extension by splitting the name string using “.” Symbol. The fun thing about extension is, a file can contain more than 1 dotes. For example, I want to name my file as “genuine.coder.image.jpg”. It is perfectly alright to use this filename and if we go for splitting and taking the string after first dot, we will get “.coder” which is definitely not what we are expecting. So the solution is to find the string after last dot and it is achieved using the code

String[] extension = listFile.getName().split("[.]");  
 String ex = extension[extension.length - 1];

So now we have the extension. All that we have to do is to check the string against the required extension (jpg,png,pdf etc) and increment the counter.

 if (ex.equalsIgnoreCase("jpg")) {  
    jpg.setText(Integer.parseInt(jpg.getText()) + 1 + "");  
 }

I found this way of incrementing the counter as a simple one (not efficient at all) since I don’t have to maintain some arrays for each separate extensions.

If the file object which is being processed is not a file, then it may be a directory. If it is, then we have to get inside of that and index them also. A simple recursive call to the function will do the trick.

Java Directory / Folder Indexing Completed

Indexing Completed Message

 if (listFile.isDirectory()) {  
      processDirectory(listFile.getAbsolutePath()); //Recursive call to processDirectoy  
 }

I have used a thread to call the processDirectory() function. If I don’t, the updating on the UI (incrementing the counter) will be lagging. Using just one new thread, it is possible to achieve better refreshing and processing rates. For this purpose, a new class named directoryProcessor is created and implemented as Runnable which is then passed as a runnable object for new Thread object. The processDirectory is called from inside the run() method of directoryProcessor.

Class directoryProcessor

class directoryProcessor implements Runnable {  
     @Override  
     public void run() {  
       processDirectory(input.getText());  
       sts.setText("Completed");  
       JOptionPane.showMessageDialog(rootPane, "Indexing Completed", "Done", JOptionPane.INFORMATION_MESSAGE);  
     }  
   }

Function processDirectory()

public void processDirectory(String dir) {  
     File fl = new File(dir);  
     sts.setText("Processing " + dir);  
     File[] listFiles = fl.listFiles();  
     for (File listFile : listFiles) {  
       if (listFile.isFile()) {  
         String[] extension = listFile.getName().split("[.]");  
         String ex = (extension[extension.length - 1]);  
         if (ex.equalsIgnoreCase("jpg")) {  
           jpg.setText(Integer.parseInt(jpg.getText()) + 1 + "");  
         } else if (ex.equalsIgnoreCase("png")) {  
           png.setText(Integer.parseInt(png.getText()) + 1 + "");  
         } else if (ex.equalsIgnoreCase("gif")) {  
           gif.setText(Integer.parseInt(gif.getText()) + 1 + "");  
         } else if (ex.equalsIgnoreCase("ppt")) {  
           ppt.setText(Integer.parseInt(ppt.getText()) + 1 + "");  
         } else if (ex.equalsIgnoreCase("doc")) {  
           doc.setText(Integer.parseInt(doc.getText()) + 1 + "");  
         } else if (ex.equalsIgnoreCase("pdf")) {  
           pdf.setText(Integer.parseInt(pdf.getText()) + 1 + "");  
         } else if (ex.equalsIgnoreCase("mp4")) {  
           mp4.setText(Integer.parseInt(mp4.getText()) + 1 + "");  
         } else if (ex.equalsIgnoreCase("flv")) {  
           flv.setText(Integer.parseInt(flv.getText()) + 1 + "");  
         } else if (ex.equalsIgnoreCase("avi")) {  
           avi.setText(Integer.parseInt(avi.getText()) + 1 + "");  
         } else if (ex.equalsIgnoreCase("exe")) {  
           exe.setText(Integer.parseInt(exe.getText()) + 1 + "");  
         } else if (ex.equalsIgnoreCase("sh")) {  
           sh.setText(Integer.parseInt(sh.getText()) + 1 + "");  
         } else if (ex.equalsIgnoreCase("jar")) {  
           jar.setText(Integer.parseInt(jar.getText()) + 1 + "");  
         } else if (ex.equalsIgnoreCase("html")) {  
           html.setText(Integer.parseInt(html.getText()) + 1 + "");  
         } else if (ex.equalsIgnoreCase("php")) {  
           php.setText(Integer.parseInt(php.getText()) + 1 + "");  
         } else if (ex.equalsIgnoreCase("css")) {  
           css.setText(Integer.parseInt(css.getText()) + 1 + "");  
         } else if (ex.equalsIgnoreCase("js")) {  
           js.setText(Integer.parseInt(js.getText()) + 1 + "");  
         }  
       } else if (listFile.isDirectory()) {  
         try {  
           processDirectory(listFile.getAbsolutePath());  
         } catch (Exception e) {  
           System.err.println("Exception - " + e.getMessage());  
         }  
       }  
     }  
   }

Java File Explorer program with Source Code
Let’s develop a basic file explorer using java. Java’s FILE class from java.io package provides simple way to represent both files and directories. That means, the same class can represent both files and directories.

This program starts by creating a new file in the root. For example we can start at C drive in windows or root(/) in Linux.

File f = new File(“C:\”);

The list of available files and folders present in the given directory can be accessed using the function listFiles(). It returns a list of files pointing to the contents inside the directory. Using a for loop buttons are created dynamically for each of these files and added to the container panel.

Handling Files

The button can be either file or folder. Using isFile() function in the FILE class, it is possible to determine whether a file is a file or directory. If it is a file, we then have to open it, if possible.

Java provides a powerful handle to the operating system using ‘Desktop’ class from java.awt package. Using Desktop we can open a file using the default program associated for it.

Desktop.getDesktop().open(FileName);

Open() throws an IOException and should be caught properly.

Handling Directories

When we encounter a directory, which is the false case for isFile(), we have to display the contents in that directory. What we have to do here is a simple recursive call to the display function using this path after removing the all currently present components in the container.

Container.removeAll() should do the trick.

After adding the new buttons, it is necessary to refresh the panel. Remember that the newly added components will not be visible until you refresh the panel using revalidate() and repaint() functions present in the Panel class.

container.revalidate(); container.repaint();

Adding a back button

It is a basic requirement for File explorers to add back buttons. In order to do so, we have to remember the history of directories. A stack is used for this purpose. Whenever a directory is accessed, its parent is added to the stack. When the back button is pressed, the top of the stack is popped and that directory is displayed.

Go to directory

Again, the same display function LoadBase() is utilized here. LoadBase taked the full pathname of directory and when the user gives the directory path directly, all that we have to do is to pass the given text to LoadBase(). The path may be invalid and it is displayed using message dialog. isExist() function in the file class helps to check whether a file/directory exists.

Install The Best Android Emulator For Ubuntu / Linux
When we consider android emulators, the first option is Google’s default Android Emulator available in the android-sdk. But on a normal computer (in my 4GB Ram, Core i3 3^rd Gen Processor Laptop) it takes around 5 minute to boot and performance is very laggy. It becomes worse after starting android studio in case you are a developer. So I started looking for a faster yet stable android emulator for Linux. Genymotion

Genymotion is the best android emulr Linux versator I have used so far. It is fast, simple and can be integrated into android studio without any additional configuration. If you are looking for an android emulator for android development or just want to run WhatsApp or something on your computer, Genymotion is the right choice. Genymotion is free for personal use and can be downloaded from their site after signup. If you want to use Genymotion for business use, try Desktop Edition For Business. Requirements

Your system must have Virtualbox virtual machine present in order to use Genymotion. If you don’t have Virtualbox download the setup for your Linux version from Virtualbox linux installation page. Install it and restart system to continue.

How To Install Genymotion In Ubuntu / Linux
- Go to this Genymotion website and make a free account.
- Login using your account and go to this download Page
  Download the right version of the setup for your computer (Select correct architecture 32bit or 64bit. If you are not sure, then download 32 bit )
- The downloaded file will be of .bin extension. Linux wont allow to run a file that is downloaded from internet. You have to give the file executable privilege to run it. To do so, open terminalEither copy and paste your file to home or change terminal working directory by using ‘cd’ command.Type chmod +x file-name.bin where file-name is the name the downloaded file
- Now, The installation will be in progress. Complete the installation
- After the installation, You can start Genymotion from your launcher/Menu. If it is not present, then start the program manually from /home/you-user name/genymotion/genymotion (You may have to make this program executable using chmod)
- Now you should see the following loading screen
- Once loaded, You should see a login prompt. For login, use your previous username and password.
- Now it is time to add a new phone to this emulator. You can do this by Clicking on the Add (+) button.
- You should see a list of available emulators here. There you can find devices with almost all android versions you have heard of. Choose any one you want and click on Next. In the new window, you can set a name for your device. Click Next.
- Wait for the downloading and installing complete. After you complete your virtual device installation, you will see the device in your Virtual Device List. Then you can add any number of emulators you want. In my case, I have added 3 of them.
- Congratulations. You have successfully added an emulator. Now it is time to run it. Select the available emulator and click on start button. Then a message box will appear saying “Initializing virtual device”

Install NetBeans with Oracle JDK in Ubuntu / Mint (Easy Way)
Programmers love to code in Linux. For me whether it is Android Studio or NetBeans, I used to get 2-3 times better speed in my Mint than in Windows. However, installing JDK offline in Linux is a tedious task. But NetBeans provides an easier way to do this. Let’s see how we can install Netbeans with Oracle JDK in linux.

Instead of installing the JDK, NetBeans only require an extracted JDK in the home directory. So let’s do it
- Download NetBeans executable for Linux (.sh File) and Oracle JDK(Download file like jdk-8uxx-linux-x64.tar.gz for x64 platform)
  
  Copy These downloaded files to Home Directory
  
  Extract The JDK in the Home folder itself
  
  Give the netbeans executable privilage using this command on terminal. Replace xx with your version.chmod +x netbeans-xxx.sh
  
  Now you can run the NetBeans setup using
  ./netbeans-xxx.sh
- The NetBeans setup will automatically detect the JDK from the HOME directory. You can proceed with the installer and finish it.
- Yeah ! You done it. Open NetBeans from your Launcher.

How to set WhatsApp Profile Pic as Contact Picture
It is always nice to see the picture of our loved ones when they call us. But downloading their photos and then setting them as contact photo is a tedious job. What if we can simply set their WhatsApp photo as contact picture. Yeah! That seems to be a pretty good idea.

But… How?

Well, there is an App for that in google play store. Let me explain the process as steps.

·    Download Contact Photo Sync from here. Install it

·    Open it. You can see all your contacts in the app. The left side photo represents your current contact photo and right side one represents the photo available in WhatsApp. Remember, the right side photo will not be available until you save the person’s picture in WhatsApp manually.

Main Screen, Left side photo represents current contact photo and right side is the available whatsapp photo.

·    Select the contact which you want to update photo.

·    The application will ask for a confirmation to launch WhatsApp. Click OK.

Confirmation to launch whatsapp

·    This will launch WhatsApp profile of the person. Click on his/her profile pic and Save it (Share -> Save to gallery).

·    When you come back to the Contact Photo Sync App, you will be given another prompt to confirm the photo update.

Confirmation to set whatsapp image as profile pic

·    Click YES, or YES, Not Show Again.

·    And yes! You are done.

All Done

Malayalam Keyboard For PC ; Windows, Linux and Mac

      Malayalam keyboard for PC / Desktop is an On-screen Malayalam keyboard that built using java programming language and will work on Windows, Linux and Mac operating systems.

Malayalam Keyboard for PC

     In the Unicode character representation Malayalam characters are available in between 0D00–0D7F hexadecimal values. In this software you can find all the Malayalam characters as buttons in the application. Clicking on the button will display corresponding character on the screen.

Normally the Malayalam characters like ‘മ്മ’ is written using മ + ് + മ and ‘ക്ക‘’using ക + ് + ക. Ii this application, I have added a shortcut to this via Mouse Right Click. For example, the normal left click on the മ will give മ itself and right click on the മ will give മ്മ. This is applicable for all characters.

Left Click On ‘മ‘

Right Click On ‘മ്മ’

   The ‘BACK’ button will give the normal backspace effect and ‘SPACE’ will do the normal space. ‘SAVE’ can be used to copy the contents in textbox to memory/clipboard which then can be pasted to other applications.

QR Code – The Quick Response Codes
QR codes as the name suggests, are much quicker and efficient than our traditional 1 dimension Barcodes. It stores data by the arrangements of dots. For technical reference, visit the Wikipedia page which explains it beautifully.

Let’s see, how to create such a QR code for our own data. There are several software available on internet. But most of them are trail versions. We need simple, free and an efficient one. FREE QR CREATOR from smp-soft is a great choice for Windows users. It is absolutely free and can be used to create Micro QR codes as well as standard ones. Micro QR codes are smaller version of normal QR codes where the area of code available is limited. It has more data density than standard ones.

A version 40 QR code can store up to 1832 characters! Which is hundreds of times more data density than Barcodes.

FREE QR Creator for Windows

Enter anything you want in the DATA box and the software automatically converts it into corresponding QR code. The generated code can be saved as jpg, bmp, png, gif, tiff or emf. It also provides the option to change the background, foreground and to add border for the code. The border can be added either at ‘top and bottom’ or at all four sides. Moreover you can copy the generated image to clipboard and then can be pasted to Paint or Photoshop like image editors.
Online QR Code Generators
QR Code Readers

QR Code Reader Device

The QR code can be decoded using smartphone applications or dedicated QR code readers. There are several apps available for our smartphones. Currently, almost all major OS platforms will provide QR code readers. QR Code readers (hardware) cost more than barcode readers since it requires a 2 Dimensional scanner.

ASCII Code for Characters in C++ program Source Code
In this tutorial, I would like to post a visual c++ console application source for a program that displays ASCII values as a table. It will be helpful in basic programming to detect the input character. You can compile this program using visual c++ or other compilers. ASCII is a set of special type of codes that will distinguish characters in computer memory. But because of its less capability for maintaining more characters and symbols, now it is replaced by UNICODE.

C program to print ASCII code and corresponding character
```
#include<iostream>

using namespace std;

void main() {

  char ch = '60';
  int counter = 60;
  while (counter < 137) {
    cout << "ASCII Code for " << ch << " is " << 'ch' << "n";
    ch++;
    ++counter;
  }
  system("pause");
  return;

}
```
ASCII Table and Description

ASCII stands for American Standard Code for Information Interchange. Computers can only understand numbers, so an ASCII code is the numerical representation of a character such as ‘a’ or ‘@’ or an action of some sort. ASCII was developed a long time ago and now the non-printing characters are rarely used for their original purpose. Below is the ASCII character table, and this includes descriptions of the first 32 non-printing characters. ASCII was actually designed for use with teletypes and so the descriptions are somewhat obscure. If someone says they want your CV however in ASCII format, all this means is they want ‘plain’ text with no formatting such as tabs, bold or underscoring – the raw format that any computer can understand. This is usually so they can easily import the file into their own applications without issues. Notepad.exe creates ASCII text, or in MS Word you can save a file as ‘text only’

GUI Simple Calculator Visual C++ Source : Windows Form Application

Today let’s work around a new interesting visual C++ (cpp) calculator with Graphical User Interface (Windows Form Application). I made this source as easier as possible. You can compile the source by downloading the project source from below.

Why is it simple calculator? It has only the basic functions of a calculator such as addition, subtraction, multiplication,division and 2 others. First Entered number is taken to the first variable a. Then select and operator, enter the second number. Do the necessary operations and When you press “=” equals button, you can see the answer right where you expect it.

More than these basic operations, you can also find the square and square root of a number. I have added buttons for this. This program make use of “math.h” which contains “sqrt()” and “power()” functions for accomplishing these tasks.

Visual Cpp Calculator

Let me know your feedback in the comments.

Use visual c++ 2010 compiler for execution.

Energy – mass Converter program c++ (cpp) source

This is a Simple C++ code for a converter program that converts energy into mass according to the famous equation from greatest scientist Albert Einstein. E= MC²

Input energy in MeV( Mega electron volt), GeV( Giga electron volt) or in Tev( Tera electron volt).

You can use visual c++ compiler for compiling and running program. You can find the Source code below. if you are using Borland turbo C++ don’t use “using namespace std;” and insert .h extension for iostream, iomanip header files. Moreover, it will not support  “system(“CLS”);” and replace it by “clrscr();”

E= MC²: –

E = Energy

M = Mass

C = speed of light in vacuum (299792458 m/s)

Let’s imagine the practical use of this equation. Consider just a stone, which weigh 250g. If you convert it completely into energy, then the total energy from the mass;

E = 0.250(kg) x 89875517873681764 (c x c)

= 22468879468420441 J

Sub shell Electron Configuration Calculator Cpp (C++) Source

There are 118 elements in our periodic table, which is the base of science. Each element has its own characteristic properties depending upon its electronic configuration. So finding electronic configuration of elements is very important.

Here is a C++ program for a sub shell electronic configuration calculator. By just typing the atomic number you can get the sub shell electronic configuration of the element. The sub shells are arranged in the increasing order of its energy. This is a windows console application. You can use visual C++ compiler to compile this program. You can download the C++ file and console .exe application from the link below.

Student Record C++(cpp) Source Code Windows Console Application

Let’s have a look at C++ source code for a student record program developed for windows console mode. You can test this code using Microsoft visual C++ compiler without any issues. I believe this sample code will help you to understand some of the basic C++ functions.

This is a menu driven program. You can add a student, get a student’s mark by entering his roll number, get a student’s details or print a table of all student’s details. This program creates a “student.dat” file at the current directory (The path at which the executable located) to save details that you have entered. During the next execution of the program the data present in the file is taken in to the memory. For deleting all existing data, you can use ’99’ command in main menu. It just delete existing file and create a new one having no records, simply a blank file.

Note – A Sticky Note application

Note is a simple text editor built .Net. This is the first application I built in my life. I built this for just getting familiarized with .Net. This is a lightweight application that can be used as a sticky note. Just run it type something on it. This software doesn’t have any saving capability.
