Czech Proxy Server

The easiest way is to try to open any site or application that requires an Internet connection. If the data download goes well, then the VPN is working properly. If there is a "No connection" error, then the VPN is not working properly for some reason.

To scrape comments from an XML file using C#, you can use the XmlDocument class, which is part of the System.Xml namespace. Here's a basic example demonstrating how to read and extract comments from an XML file:

using System;
using System.Xml;

class Program
{
    static void Main()
    {
        string xmlFilePath = "path/to/your/xml/file.xml"; // Replace with the path to your XML file

        try
        {
            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.Load(xmlFilePath);

            // Extract comments from the XML document
            ExtractComments(xmlDoc);
        }
        catch (Exception ex)
        {
            Console.WriteLine($"Error: {ex.Message}");
        }
    }

    static void ExtractComments(XmlDocument xmlDoc)
    {
        XmlNodeList commentNodes = xmlDoc.SelectNodes("//comment()");

        if (commentNodes != null)
        {
            foreach (XmlNode commentNode in commentNodes)
            {
                // Print or process the comment content
                string commentContent = commentNode.Value;
                Console.WriteLine($"Comment: {commentContent}");
            }
        }
        else
        {
            Console.WriteLine("No comments found in the XML document.");
        }
    }
}

In this example:

1. Replace the xmlFilePath variable with the actual path to your XML file.
2. The XmlDocument class is used to load the XML file.
3. The ExtractComments method uses an XPath expression (//comment()) to select all comment nodes in the XML document.
4. The comments are then printed or processed as needed.

Make sure to handle exceptions appropriately and adapt the code based on the structure of your XML file. If your XML file is hosted on the web, you can use XmlDocument.Load with a URL instead of a local file path.

You can bypass the blocking of the messenger by using the built-in proxy server in the application. To do this, go to "Settings" and then to the section "Data and storage". Here, in the "Proxy settings" tab, you will find the "Add proxy" item. A shield icon on the top line of the menu will indicate that the proxy is enabled.

SIP is a virtual telephony service. A proxy server in this case is used to collect traffic, its conversion and further transmission to the subscriber via cellular communication. It is mainly used by call centers to communicate with customers.

Open the "Browser Properties" in the control panel, in the "Connections" section of the opened window select "Network Settings". Remove the check mark from the "Use proxy" item, click "OK".
