Provides required tables and data for multilanguage projects

Introduction

This article contains MUST HAVE tables and data for proper multi language development. I highly recommend to use ISO (International Organizations for Standardization) as the primary source of information, because this is the only way to go for high quality products and compatibility. Please remember that ISO usually only manages standards. Behind each ISO standard, there are companies which supply databases and updates to commercial users. Internet is also a good source of information so I've collected globalization data from various resources and placed into 6 tables. If you have some suggestions, then please contact me by email: Evaldas Jocys <evaldas@jocys.com>.

Data for these tables are required to produce full multilingual support:

  1. Languages - Information about all languages
  2. Cultures - Information about all cultures (Language + Country)
  3. Encodings - Information about all encodings
  4. Ranges - Can help to get customer's culture by IP
  5. Currencies - Business information about each country
  6. Currencies by Country- Currencies used in country

Requirements

  1. Microsoft SQL Server 2005
  2. Microsoft .NET Framework 3.5

Installation

  1. Download ZIP file specified above.
  2. Extract ZIP contents into temp folder.
  3. Navigate to WebApp\Projects\Globalization\SQL\ folder.
  4. Open Globalization-SqlDataImport.bat file.
  5. Go to line 5 and update srv value with your SQL Server name.
  6. Go to line 6 and update cat value with your Database name.
  7. Save and close Globalization-SqlDataImport.bat file.
  8. Execute Globalization-SqlDataImport.bat to recreate [Globalization_*] tables and data.
    Note: Import script will ask for database login and password. Hit [Enter] key if you want to use trusted connection.

Using the Code

Archive contains .zip\Engine folder with LINQ to SQL classes and some methods. You can extract content of this folder into your C# project. For example, Engine\Globalization\Ranges.cs file contains two functions...

/// <summary>
/// Convert IP Address string to long number.
/// </summary> 
/// <param name="ipString">IP Address string: 64.233.167.99</param> 
/// <returns>Numeric representation of IP Address</returns>
public long IpToInt(string ipString)
{
    System.Net.IPAddress address = System.Net.IPAddress.Parse(ipString);
    return (long)BitConverter.ToUInt32(address.GetAddressBytes().Reverse().ToArray(), 0);
}

/// <summary>
/// Get Alpha 3 Code of country by IP Address.
/// </summary>
/// <param name="ipString">IP Address string: 64.233.167.99</param>
/// <returns>ISO 3166-1 Alpha-3 Code. For example: LTU</returns>
public string GetCountryByIp(string ipString)
{
    Data.GlobalizationDataContext db = new Data.GlobalizationDataContext();
    long ip = IpToInt(ipString);
    Data.Range range = db.Ranges.SingleOrDefault
            (item => item.RangeStart <= ip && ip <= item.RangeEnd);
    return (range == null) ? string.Empty : range.CountryA3;
}    

So you can get country code of the visitor and redirect him/her to a specific web page:

// Get visitor's IP Address.
string ipString = Request.ServerVariables["REMOTE_ADDR"];
// Get ISO 3166-1 Alpha-3 Code of Country by IP Address.
string countryA3 = 
    Engine.AppContext.Current.Globalization.Ranges.GetCountryByIp(ipString);
// Define default language of user: 
// Lithuanian if user came from Lithuania or English for all other countries.
string language = (countryA3 == "LTU") ? "ltu" : "enu";
// Redirect user to specific page.
System.Web.HttpContext.Current.Response.Redirect("Default_" + language + ".htm", true);
