Zamunda Proxy

It means that the address of such a server changes periodically. This is useful if the user wants to be as anonymous as possible when surfing the web.

Both versions of the protocol, at first glance, are able to provide anonymity on the Internet, as well as bypass all kinds of blockages. In addition, they are not only suitable for online entertainment, but also for work (study). This is what unites them to some extent, but there are still more differences. These are primarily the number of IP addresses, the cost of rent, appearance, connection speed, ping, and security. The IPv4 protocol, developed in the 1980s, is a more outdated model with a number of significant problems, including inefficient routing.

Several virtual proxy servers can be created within one device. These are special dedicated servers that only "service" such traffic. Many devices can connect to them at the same time.

When working with OpenXML, you may need to parse date values from date-formatted cells in Excel spreadsheets. The date values in OpenXML are represented as numeric values, and you need to convert these numeric values to DateTime objects.

Here's an example using C# and the DocumentFormat.OpenXml library to parse date values from an Excel spreadsheet:

1. Install the Open XML SDK:

   • If you haven't already, install the DocumentFormat.OpenXml NuGet package:

nuget install DocumentFormat.OpenXml

Write the Parsing Code:

• Create a C# script or add the following code to your project:

using System;
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Spreadsheet;

class Program
{
    static void Main()
    {
        string filePath = "path/to/your/excelfile.xlsx"; // Replace with the path to your Excel file

        // Call the function to parse dates from the Excel file
        ParseDatesFromExcel(filePath);
    }

    static void ParseDatesFromExcel(string filePath)
    {
        using (SpreadsheetDocument spreadsheetDocument = SpreadsheetDocument.Open(filePath, false))
        {
            WorkbookPart workbookPart = spreadsheetDocument.WorkbookPart;
            SharedStringTablePart sharedStringTablePart = workbookPart.GetPartsOfType().FirstOrDefault();

            if (sharedStringTablePart != null)
            {
                foreach (WorksheetPart worksheetPart in workbookPart.WorksheetParts)
                {
                    foreach (Cell cell in worksheetPart.Worksheet.Descendants())
                    {
                        if (cell.DataType != null && cell.DataType.Value == CellValues.SharedString)
                        {
                            int sharedStringIndex = int.Parse(cell.InnerText);
                            string sharedStringValue = sharedStringTablePart.SharedStringTable.Elements().ElementAt(sharedStringIndex).InnerText;

                            if (DateTime.TryParse(sharedStringValue, out DateTime parsedDate))
                            {
                                Console.WriteLine($"Parsed Date: {parsedDate.ToShortDateString()}");
                            }
                            else
                            {
                                Console.WriteLine("Not a valid date format.");
                            }
                        }
                        else if (cell.CellValue != null)
                        {
                            if (DateTime.TryParse(cell.CellValue.Text, out DateTime parsedDate))
                            {
                                Console.WriteLine($"Parsed Date: {parsedDate.ToShortDateString()}");
                            }
                            else
                            {
                                Console.WriteLine("Not a valid date format.");
                            }
                        }
                    }
                }
            }
        }
    }
}

2. • Replace "path/to/your/excelfile.xlsx" with the actual path to your Excel file.

3. Run the Code:

   • Execute the code, and it will print parsed date values from the Excel file.

This code uses the SpreadsheetDocument class from the DocumentFormat.OpenXml.Packaging namespace to open the Excel file, and it iterates through the cells to parse and print date values. It checks if the cell contains a shared string (string stored in the shared string table) or a direct value. If it's a valid date, it parses and prints it. Adjust the code according to your specific needs and Excel file structure.

If you are interested in a quality and fast proxy server, do not look for it among the free options. All of them, although they seem to be profitable, in fact do not differ in duration of work and speed. It is recommended to buy quality proxies from reputable proxy service providers that are widely available on the Internet.
