Creating a Windows application in Java using Eclipse

Step 1: Create a new Java Application In Eclipse select File > New > Java Project: Step 2: Create a new Frame In Eclipse, right click the 'src' folder and select New > Other. In the wizard dialog that appears select WindowBuilder > Swing Designer > JFrame: Click Next. Give your JFrame a name: Click Finish. Note how the following code for gui.java gets generated: [code language="java"] import java.awt.BorderLayout; public class gui extends JFrame { private JPanel contentPane; /** * Launch the application. */ public static void main(String[] args) { EventQueue.invokeLater(new Runnable() { public void run() { try { gui frame = new gui(); frame.setVisible(true); } catch (Exception e) { e.printStackTrace(); } } }); } /** * Create the frame. */ public gui() { setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setBounds(100, 100, 450, 300); contentPane = new JPanel(); contentPane.setBorder(new EmptyBorder(5, 5, 5, 5)); contentPane.setLayout(new BorderLayout(0, 0)); setContentPane(contentPane); } } [/code] Step 3: Build and fix compiler warnings Note also when building the project we get the one warning: "The serializable class gui does not declare a static final serialVersionUID field of type long gui.java /WindowsApp/src line 9 Java Problem" Click your mouse pointer over by the warning symbol and allow Eclipse to correct it: On building and running the project we have our bare minimum Windows application as shown:

Using the Supervisor Controller Pattern to access View controls in MVVM

As discussed on a StackOverflow post , this is considered bad practice, so only use this when necessary. Step 1: Create a new WPF project Step 2: Add event handling code A number of classes are needed for doing command bindings in MVVM. Create the following classes and add to your Visual Studio project: RelayCommand.cs [code language="csharp"] using System; using System.Windows.Input; namespace SupervisorControllingPattern { public class RelayCommand<T> : ICommand { private readonly Predicate<T> _canExecute; private readonly Action<T> _execute; public RelayCommand(Action<T> execute) : this(execute, null) { _execute = execute; } public RelayCommand(Action<T> execute, Predicate<T> canExecute) { if (execute == null) throw new ArgumentNullException(nameof(execute)); _execute = execute; _canExecute = canExecute; ...

Getting started with client-server applications in C++

Image
A demonstration of simple Internet client-server applications in C++ (Linux-based). The client application tries to connect to the remote server application using the IP address of the remote server ('localhost' or 127.0.0.1) and the server port number which defaulted to 1234. The server application listens to port number 1234 for a connection request. When the server application receives the connection request it sends the text message "Hello!\r\n" to the client.

How to send an e-mail via Google SMTP using C#

First things first, some useful StackOverflow links: https://stackoverflow.com/questions/9201239/send-e-mail-via-smtp-using-c-sharp https://stackoverflow.com/questions/17462628/the-server-response-was-5-7-0-must-issue-a-starttls-command-first-i16sm1806350 To demonstrate how this is done I first create a new Visual Studio project: Some example code for sending an email via a Google email account (smtp.goolgle.com) - obviously replace this with email / credentials of your own... I put the code within a try-catch block in order to capture any errors that may occur while attempting this. [code language="csharp"] using System; using System.Net; using System.Net.Mail; namespace EmailSmtp { class Program { static void Main(string[] args) { try { // Credentials var credentials = new NetworkCredential("someEmail@gmail.com", "somePassword"); // Mail message var ...
