Console Server Code

In this article, we will be discussing the console server code. We will walk through the different functionalities of the code and how it works. Let's dive in!

Introduction

The console server code is a server-side code that receives and outputs data to the user. It is designed to work in a console environment and is currently being developed to work in a windowed environment as well. In this article, we will explore the various functionalities and components of the console server code.

Creating a Simple Server

One of the functionalities of the console server code is the ability to Create a simple server. Although the server code is still a work in progress and may experience crashes, it is functional to a certain extent. The server code allows for the establishment of a connection and handles events such as user additions, disconnections, and message broadcasting.

User Add Functionality

The console server code includes a user add functionality, which allows for the addition of a user to the server. When the server receives the data indicating a user connection, it adds the user's username to a list of online users. This functionality is essential for keeping track of users who are currently connected to the server.

Disconnect Functionality

In addition to the user add functionality, the console server code also handles disconnections. When a user disconnects from the server, the server notifies all the connected users about the disconnection. It removes the user's name from the list of online users and broadcasts a message indicating that the user is no longer online.

Broadcasting Messages

The console server code includes a "tell everyone" method, which allows for the broadcasting of messages to all connected users. The method iterates through the list of online users and sends the message to each user individually. This functionality ensures that messages are delivered to all users in real-time.

Chat Data

Another functionality of the console server code is the handling of chat data. When a message is sent by a user, the server rebroadcasts the message to all connected users. The server parses the received data and identifies it as chat data, which triggers the "tell everyone" method. This ensures that the message is displayed to all users, creating a seamless chat experience.

Catching Errors

To handle any potential errors that may occur, the console server code includes a catch statement. If any part of the code fails to execute successfully, the catch statement displays a message indicating that no conditions were met. This helps in identifying and resolving any issues that may arise during the execution of the server code.

Running the Code

To run the console server code, You will need to have both the client and server projects available. The code can be executed by running the server file, which will open a console window where the output will be displayed. The server code works in conjunction with the client code, allowing for communication between users.

Conclusion

In conclusion, the console server code provides the functionality needed for establishing a server and handling user connections, disconnections, and message broadcasting. While still a work in progress, the code demonstrates the fundamentals of server-side programming. With further development, it can be extended to work in a GUI environment, enhancing the user experience and functionality.
