Microsoft Store Proxy

Go to the settings (the icon in the form of three dots) and open the section "Settings". In the tab at the very bottom, click on "Advanced settings". Click on "Open proxy settings for computer" and in the window that appears, click on "Network settings". Find the line "Automatic detection of parameters", uncheck it, and then, in the section "Proxy", activate the option "Use a proxy server". Enter the proxy host and port in the appropriate fields, and then click "Apply".

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.

In UDP communication, there is no built-in mechanism to confirm if the client has received data from the server. UDP is a connectionless protocol, which means it does not establish a connection between the client and server, and therefore, it does not provide any reliability guarantees.

However, there are some techniques you can use to improve the reliability of UDP communication and get an indication that the client has received data:

1. Acknowledgment packets: The server can send acknowledgment packets after sending data to the client. The client can then send acknowledgment packets back to the server after receiving the data. If the server does not receive the acknowledgment packets within a specific timeout period, it can assume that the client has not received the data.

2. Timeout and retransmission: The server can implement a timeout and retransmission mechanism. If the server does not receive an acknowledgment packet within a specific timeout period, it can resend the data and continue to do so until it receives an acknowledgment or reaches a predefined limit.

3. Checksums or hashes: The server can send data along with a checksum or hash value. The client can then calculate the checksum or hash of the received data and compare it with the value sent by the server. If the values match, the client can be confident that it has received the data correctly.

To obtain an OAuth2 access token for an unknown service, you will need to follow these general steps. Keep in mind that the exact process may vary depending on the service provider and their OAuth2 implementation.

1. Identify the service provider: Determine the service provider you want to access using OAuth2. This could be a third-party application or API.

2. Check the service provider's documentation: Visit the service provider's official documentation or developer portal to find information about their OAuth2 implementation, including the authorization endpoint, token endpoint, and any required scopes or parameters.

3. Register your application: In most cases, you will need to register your application with the service provider to obtain a client ID and client secret. This is usually done through a dedicated developer portal or console. During registration, you may need to provide information about your application, such as its name, description, and redirect URIs.

4. Obtain authorization code: Direct the user to the service provider's authorization endpoint with the necessary parameters, such as the client ID, client secret, and the desired scopes. The user will be prompted to log in and grant your application access to the requested permissions. Upon successful authentication, the service provider will redirect the user to your application's redirect URI with an authorization code in the URL.

5. Exchange authorization code for an access token: Use your application's backend server to make a POST request to the service provider's token endpoint with the following parameters: client ID, client secret, authorization code, redirect URI, and (optionally) a grant type (usually "authorization_code"). The service provider will respond with an access token, which can be used to authenticate requests to their API on behalf of the user.

6. Store and use the access token: Save the access token securely in your application or cache, and use it in the Authorization header of your API requests to the service provider. Access tokens typically have an expiration time, so you may need to periodically refresh them using a refresh token or by repeating the authorization flow.

To get a token from local storage, you can use the JavaScript localStorage object, which allows you to store key-value pairs in the browser's local storage. Here's how to get a token from local storage:

Access the token: You can access the token stored in local storage by using the localStorage.getItem() method. This method takes a key as an argument and returns the value associated with that key.

For example, if you have stored a token with the key "authToken", you can retrieve it like this:

const token = localStorage.getItem("authToken");

Use the token: Once you have the token, you can use it in your application as needed. For example, you can include it in the Authorization header of your API requests:

const headers = {
  "Authorization": `Bearer ${token}`,
  // other headers...
};

Remember that local storage is limited to string values, so if your token is an object or has special characters, you might need to encode or serialize it before storing it and then decode or deserialize it when retrieving it.
