Proxy Recycler

In the "System Settings" section, open the "Network" tab, and then, when you highlight the active connection, click "Advanced". Here, in the "Proxies" tab, tick only the HTTP proxy if you do not intend to use other types of proxies temporarily. Enter the address of your proxy server and its port in the designated fields and click "OK".

If you want to parse JSON data and display it in a TreeView in a Windows Forms application using C#, you can use the Newtonsoft.Json library for parsing JSON and the TreeView control for displaying the hierarchical structure. Below is an example demonstrating how to achieve this

Install Newtonsoft.Json

Use NuGet Package Manager Console to install the Newtonsoft.Json package:

Install-Package Newtonsoft.Json

• Create a Windows Forms Application:

  • Open Visual Studio and create a new Windows Forms Application project.

• Design the Form:

  • Drag and drop a TreeView control and a Button on the form.

• Write Code to Parse JSON and Populate TreeView:

using System;
using System.Windows.Forms;
using Newtonsoft.Json.Linq;

namespace JsonTreeViewExample
{
    public partial class MainForm : Form
    {
        public MainForm()
        {
            InitializeComponent();
        }

        private void btnLoadJson_Click(object sender, EventArgs e)
        {
            // Replace with your JSON data or URL
            string jsonData = @"{
                ""name"": ""John"",
                ""age"": 30,
                ""address"": {
                    ""city"": ""New York"",
                    ""zip"": ""10001""
                },
                ""emails"": [
                    ""john@example.com"",
                    ""john.work@example.com""
                ]
            }";

            // Parse JSON data
            JObject jsonObject = JObject.Parse(jsonData);

            // Clear existing nodes in TreeView
            treeView.Nodes.Clear();

            // Populate TreeView
            PopulateTreeView(treeView.Nodes, jsonObject);
        }

        private void PopulateTreeView(TreeNodeCollection nodes, JToken token)
        {
            if (token is JValue)
            {
                // Display the value
                nodes.Add(token.ToString());
            }
            else if (token is JObject)
            {
                // Display object properties
                var obj = (JObject)token;
                foreach (var property in obj.Properties())
                {
                    TreeNode newNode = nodes.Add(property.Name);
                    PopulateTreeView(newNode.Nodes, property.Value);
                }
            }
            else if (token is JArray)
            {
                // Display array items
                var array = (JArray)token;
                for (int i = 0; i < array.Count; i++)
                {
                    TreeNode newNode = nodes.Add($"[{i}]");
                    PopulateTreeView(newNode.Nodes, array[i]);
                }
            }
        }
    }
}

4. • In this example, the btnLoadJson_Click event handler simulates loading JSON data. You should replace it with your method of loading JSON data (e.g., from a file, a web service, etc.).
   • The PopulateTreeView method recursively populates the TreeView with nodes representing the JSON structure.

5. Run the Application:

   • Build and run your application. Click the button to load the JSON data into the TreeView.

This example assumes a simple JSON structure. You may need to adjust the code based on the structure of your specific JSON data. The PopulateTreeView method handles objects, arrays, and values within the JSON data.

To scrape JSON data using RxJava in a Java application, you can use the RxJava library along with an HTTP client library to make requests. Below is an example using RxJava2 and OkHttp to scrape JSON data from a URL asynchronously.

Add Dependencies

Add the following dependencies to your project:

    io.reactivex.rxjava2
    rxjava
    2.x.y 




    com.squareup.okhttp3
    okhttp
    4.x.y 

Write the Code:

import io.reactivex.Observable;
import io.reactivex.schedulers.Schedulers;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

public class JsonScrapingExample {

    public static void main(String[] args) {
        String url = "https://api.example.com/data"; // Replace with your JSON API URL

        // Create an Observable that emits a single item (the URL)
        Observable.just(url)
                .observeOn(Schedulers.io()) // Specify the IO thread for network operations
                .map(JsonScrapingExample::fetchJson)
                .subscribe(
                        jsonData -> {
                            // Process the JSON data (replace this with your scraping logic)
                            System.out.println("Scraped JSON data: " + jsonData);
                        },
                        Throwable::printStackTrace
                );
    }

    // Function to fetch JSON data using OkHttp
    private static String fetchJson(String url) throws Exception {
        OkHttpClient client = new OkHttpClient();
        Request request = new Request.Builder()
                .url(url)
                .build();

        try (Response response = client.newCall(request).execute()) {
            if (!response.isSuccessful()) {
                throw new Exception("Failed to fetch JSON. HTTP Code: " + response.code());
            }

            // Return the JSON data as a string
            return response.body().string();
        }
    }
}

2. • Replace the url variable with the actual URL of the JSON API you want to scrape.
   • The fetchJson function uses OkHttp to make an HTTP request and fetch the JSON data.

3. Run the Code:

   • Execute the Java code to fetch and process the JSON data asynchronously using RxJava.

This example uses RxJava's Observable to create an asynchronous stream of events. The observeOn(Schedulers.io()) part specifies that the network operation (fetchJson) should run on the IO thread to avoid blocking the main thread.

Make sure to handle exceptions appropriately and adjust the code based on the structure of the JSON API you are working with.

A firewall is responsible for filtering packets of traffic. For example, it blocks access to the Internet for certain applications. There are many more options for using a proxy. But if you install special software, it can also be used for such purposes.

If your ISP blocks you from downloading torrents, turning on your proxy server is the easiest way around the blockage. How exactly this is done depends on the torrent client you are using. For example, in Qbittorrent you need to go to settings, open "Network" tab, check "Proxy-server" and manually specify its settings. The same way uTorrent is configured.
