To see all the services on your system, use the Get-Service cmdlet:

Get-Service

This outputs a list showing:

• Name: The internal service name.
• DisplayName: A user-friendly name.
• Status: Indicates whether the service is running, stopped, or paused.

This command helps you get an overview of all services and their current state.

PowerShell is a powerful tool for managing system services, offering flexibility and control through straightforward commands. This guide covers the essentials of listing, searching, and managing services.

JavaScript functions are reusable blocks of code that perform specific tasks. Defined using the function keyword or as arrow functions, they can accept parameters and return values. Functions enhance code organization, modularity, and reusability, allowing developers to execute the same logic multiple times throughout a program with ease.

Problem Statement: Extracting extended file properties, such as the Media Created Date, is necessary for certain applications. Utilizing the Microsoft.WindowsAPICodePack.Shell namespace facilitates this task efficiently.

Approach: Utilize the ShellObject class from the WindowsAPICodePack.Shell namespace to access extended file properties. Specifically, retrieve the Media Created Date using the System.Media.DateEncoded property.

using Microsoft.WindowsAPICodePack.Shell;

ShellObject shell = ShellObject.FromParsingName(path);
var mediaCreatedDate = shell.Properties.System.Media.DateEncoded;

Explanation: This code utilizes the ShellObject class to access extended file properties. It fetches the Media Created Date of a file specified by its path using the System.Media.DateEncoded property, providing crucial metadata for various applications.

useContext is a React Hook that lets you read and subscribe to context from your component. React Context is a way to manage state globally.

The useNavigate hook from React Router returns a function that lets you navigate programmatically, for example in an effect:

import { useNavigate } from "react-router-dom";

function useLogoutTimer() {
  const userIsInactive = useFakeInactiveUser();
  const navigate = useNavigate();

  useEffect(() => {
    if (userIsInactive) {
      fake.logout();
      navigate("/session-timed-out");
    }
  }, [userIsInactive]);
}

Button click

import { useNavigate } from 'react-router-dom';
...
const navigate = useNavigate();
...
<Button onClick={() => navigate('../user', { replace: true })}>Register</Button>

To only update one field, we can simply change the update method to the following:

Person person = new Person {Id=4, Lastname="Miller"};
dbContext.Attach(person);
dbContext.Entry(person).Property(p => p.Lastname).IsModified = true;
dbContext.SaveChanges();

The above function first constructs the object with the specified Id and updated Lastname, and then appends the object; it then explicitly marks the Lastname property as modified.  

The generated UPDATE statement now looks like this

info: Microsoft.EntityFrameworkCore.Database.Command[20101]
      Executed DbCommand (8ms) [Parameters=[@p1='?' (DbType = Int32), @p0='?' (Size = 4000)], CommandType='Text', CommandTimeout='30']
      UPDATE `Persons` SET `Lastname` = @p0
      WHERE `Id` = @p1;
      SELECT ROW_COUNT();

As shown in the EFCore log, only the Lastname field is updated.  

This approach can slightly improve performance because the SQL statement is smaller and the query execution on the database server can be faster.

Logging is an essential part of application development for debugging, monitoring, and understanding the flow of execution, especially in complex systems. When logging in a C# method with parameters that need validation, it's crucial to follow best practices to ensure clear and useful log messages. Below is a sample demonstrating how to log and validate parameters in a C# method:

public bool ValidateAndProcessData(string data)
{
    // Log the start of the method
    _logger.LogInformation("ValidateAndProcessData method started");

    // Validate input data
    if (string.IsNullOrEmpty(data))
    {
        _logger.LogError("Input data is null or empty");
        throw new ArgumentException("Input data cannot be null or empty", nameof(data));
    }

    try
    {
        // Process data
        _logger.LogInformation("Processing data: {data}", data);

        // Simulating processing time
        System.Threading.Thread.Sleep(1000);

        _logger.LogInformation("Data processed successfully");
        return true;
    }
    catch (Exception ex)
    {
        // Log any exceptions that occur during processing
        _logger.LogError(ex, "Error processing data: {data}", data);
        throw; // Re-throw the exception for higher-level handling
    }
    finally
    {
        // Log the end of the method
        _logger.LogInformation("ValidateAndProcessData method completed");
    }
}

By following this sample, you ensure that your method logs relevant information about parameter validation and method execution, making it easier to debug and monitor your application's behavior.

C# is a strongly-typed language. It means we must declare the type of a variable that indicates the kind of values it is going to store, such as integer, float, decimal, text,

C# includes specialized classes that store series of values or objects are called collections.

There are two types of collections available in C#: non-generic collections and generic collections.

The System.Collections namespace contains the non-generic collection types and System.Collections.Generic namespace includes generic collection types.

In C#, a string is a series of characters that is used to represent text. It can be a character, a word or a long passage surrounded with the double quotes ". The following are string literals.

// String Literal Examples
"S"
"String"
"This is a string."

In a console apps, there is often a need to obtain user input from the console while ensuring that the input is not empty or only whitespace characters.

In this sample, we define a method GetUserInput that takes an optional message parameter. It continuously prompts the user until a non-empty, non-whitespace input is provided.

static string GetUserInput(string message = "Please enter some input:")
{
    string input;
    do
    {
        Console.WriteLine(message);
        input = Console.ReadLine()?.Trim();
    } while (string.IsNullOrWhiteSpace(input));
    return input;
}

Explanation:

• message parameter allows customizing input prompt message.
• Console.ReadLine()?.Trim() reads user input and trims leading/trailing whitespace.
• The ?. operator is used for null-conditional access, ensuring that Console.ReadLine() doesn't throw a null reference exception if the input is null.
• do-while loop ensures user input is not empty or whitespace.

To filter out nullable strings and obtain only non-null strings, you can use LINQ Where method along with a null check. Here's an example:

IEnumerable<string?> nullableStrings //

List<string> nonNullStringsList = nullableStrings
    .Where(s => s != null) // Filter out null values
    .Select(s => s!)       // Convert nullable strings to non-nullable
    .ToList();             // Convert IEnumerable to List

1. We use LINQ extension methods Where to filter out null values and Select to convert nullable strings to non-nullable strings (string! indicates a non-nullable reference type in C# 8.0 and later).
2. Finally, we use ToList() to convert the filtered enumerable to a List<string>.

The JsonSerializer.Serialize converts the value of a specified type into a JSON string.

using System.Text.Json;

var user = new User("Krish Jackon", "female", new MyDate(1985, 03, 30));

var json = JsonSerializer.Serialize(user);
Console.WriteLine(json);

The JsonSerializer.Deserialize parses the text representing a single JSON value into an instance of a specified type.

using System.Text.Json;

string json = @"{""Name"":""Krish Jackon"", ""Gender"":""female"",
    ""DateOfBirth"":{""year"":1985,""month"":03,""day"":30}}";

var user = JsonSerializer.Deserialize<User>(json);

Who doesn't know this? You have something on your mind and want to tell the other person how you feel and what's on your mind. However, the other person, unfortunately, does not listen properly and you do not feel understood. 

Unfortunately, most people are poor listeners. Good listeners have often undergone special training or have made listening to their profession. But what does good listening actually mean? How can you listen better and give your counterpart an appreciative feeling? In the following, I would like to show you three tips that will help you become a better listener.

Doesn’t it make sense then to try to save as much of your hard-earned money as possible? The less you spend, the more you have.

Here are some money tips you can use to save big on many of your expenses.

Vasily Alekseyev was tricked into lifting 500 pounds over his head.

Until 1970, many weightlifters had only come close to cracking that psychological barrier.

So when his trainers told him that the bar was loaded with slightly less than 500 pounds, a weight he’d lifted before, he threw it up like a matchstick.

Only they had lied—he’d actually lifted 500.5 pounds. Over the next seven years, he continued to smash records, topping out at 564 before retiring.

Because seeing is believing, many others started lifting 500+ soon after.

Remember Roger Bannister? Until 1954, everyone believed a human couldn't run a mile in under four minutes. Then Roger did it, and his record stood for only 46 days. In the next 50 years, more than a thousand runners beat the four-minute mile.

What changed? Only a belief in what’s possible.

Walking barefoot is the natural way for humans to walk why it's worthwhile to go barefoot more often.

For thousands of years, our ancestors stomped around barefoot. Only recently have people started to squeeze into socks and shoes with rubber soles, completely isolating themselves from the earth's surface - yet walking with bare feet brings so many health benefits. Because walking barefoot...

Too many tasks and too little time is a permanent condition for you? Do you feel stressed and are unproductive? Poor time management is often to blame. With these 5 tips, you'll finally get the hang of it.

The consequences: Constant stress and declining productivity. These tips (from Focus Online) show you how good time management works and bring peace back into your workday.

Our society places great value on multitasking. So, too, are our work environments designed for multitasking: Now more than ever, we use computers and networks that offer instant messaging, email, and other "productive" tools. We are constantly jumping back and forth between them.

Multitasking includes three different types:

Performing two or more tasks simultaneously.

Switching back and forth between tasks.

Performing a series of tasks in rapid succession.

While this way of working seems normal to many people, multitasking is a disadvantage. If we use single-tasking instead and consciously approach each project "task-by-task," we can be very productive.

The fastest way to get many things done is to do one thing at a time.

At least two liters a day should be. You should definitely drink before sports ... There are plenty of myths about drinking. But which ones are really true?
