Zap Proxy

Open the browser settings and go to the "Advanced" section. Click on "System" and then, in the window that opens, click on "Open proxy settings for computer". A window will appear in front of you, showing all the current settings. Another way to find out the http proxy is to download and install the SocialKit Proxy Checker utility on your computer.

The easiest option is to use ready-made online proxy checkers. For example, Hidemy.name, which shows the type of protocol used. Or you can simply run Speedtest - this will show you the bandwidth and response speed (ping).

To scrape images in C#, you can use the HTMLAgilityPack library for parsing HTML and retrieving image URLs. Here's a basic example

Install HTMLAgilityPack

You can install the HTMLAgilityPack NuGet package using the following command in the Package Manager Console:

Install-Package HtmlAgilityPack

Write a C# script to scrape images:

using System;
using System.Collections.Generic;
using HtmlAgilityPack;

class Program
{
    static void Main()
    {
        string url = "https://example.com"; // Replace with the URL of the page you want to scrape images from

        // Download HTML content from the URL
        HtmlWeb web = new HtmlWeb();
        HtmlDocument document = web.Load(url);

        // Extract image URLs
        List imageUrls = ExtractImageUrls(document, url);

        // Print the extracted image URLs
        foreach (string imageUrl in imageUrls)
        {
            Console.WriteLine(imageUrl);
        }
    }

    static List ExtractImageUrls(HtmlDocument document, string baseUrl)
    {
        List imageUrls = new List();

        // Select image elements using XPath
        var imageElements = document.DocumentNode.SelectNodes("//img[@src]");

        if (imageElements != null)
        {
            foreach (var imageElement in imageElements)
            {
                // Extract image URL from the src attribute
                string imageUrl = imageElement.GetAttributeValue("src", "");

                // Make the URL absolute if it's a relative URL
                imageUrl = new Uri(new Uri(baseUrl), imageUrl).AbsoluteUri;

                // Add the URL to the list
                imageUrls.Add(imageUrl);
            }
        }

        return imageUrls;
    }
}

This script uses HTMLAgilityPack to load the HTML content of a webpage and extract image URLs using XPath. The ExtractImageUrls method selects image elements with the XPath query "//img[@src]", retrieves the src attribute, and converts relative URLs to absolute URLs.

Run the script:

Replace the url variable with the URL of the webpage you want to scrape images from.

Run the script to see the list of image URLs.

The error message "cannot create temp dir for user data dir" typically occurs when Selenium is unable to create a temporary directory for its user data. This issue can be caused by several factors, such as insufficient permissions or a full disk.

Here are some steps you can take to resolve this issue:

Check available disk space:

Ensure that your system has enough free disk space to create a temporary directory. If your disk is almost full, consider clearing some space or moving files to another storage location.

Check permissions:

Make sure that your user account has the necessary permissions to create and modify files and directories in the specified location. You can try changing the permissions of the directory or creating a new directory with the appropriate permissions.

Specify a custom user data directory:

You can specify a custom user data directory for Selenium by using the --user-data-dir option in the ChromeOptions class. This allows you to choose a location with enough free space and the appropriate permissions.

Here's an example of how to set a custom user data directory in Python:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

chrome_options = Options()
chrome_options.add_argument("--user-data-dir=/path/to/custom/user/data/dir")

driver = webdriver.Chrome(options=chrome_options)
driver.get('your_url')

# Rest of your code

driver.quit()

Replace /path/to/custom/user/data/dir with the path to the directory you want to use as the user data directory.

Check for antivirus or security software interference:

Sometimes, antivirus or security software can interfere with the creation of temporary directories. Try temporarily disabling your antivirus or security software to see if it resolves the issue. If it does, you may need to add an exception for Selenium or change your antivirus settings.

Restart your system:

In some cases, simply restarting your system can resolve the issue. This can help free up disk space and resolve any temporary issues with permissions or disk access.

If you've tried all these steps and are still encountering the error, please provide more information about your system, including the operating system, disk space, and any relevant error messages or logs. This will help diagnose the issue further and find a suitable solution.

In Windows 8 and later editions it is recommended to setup network proxy through Group Policy. To do this, run GPMC.msc (via "Run" or enter in the "Search"), then select the section with the users, from the list of parameters select "Internet Settings". Further settings are not different from the standard ones in Windows. You can set proxy, specify the start page, enter restrictions and so on.
