How to use Windows' Customized Region and Language settings in WPF
See the question and my original answer on StackOverflowOne solution to this is to create this Namibian CultureInfo, so its fully recognized by all .NET layers. Here is a code that does it:
public static void RegisterNamibianCulture()
{
// reference the sysglobl.dll assembly for this
CultureAndRegionInfoBuilder namibianCulture = new CultureAndRegionInfoBuilder("en-NA", CultureAndRegionModifiers.None);
// inherit from an existing culture
namibianCulture.LoadDataFromCultureInfo(new CultureInfo("en-za"));
namibianCulture.CultureEnglishName = "Namibia";
namibianCulture.RegionEnglishName = "Namibia";
namibianCulture.CultureNativeName = "Namibia"; // you may want to change this
namibianCulture.RegionNativeName = "Namibia"; // you may want to change this
// see http://en.wikipedia.org/wiki/ISO_3166-1, use user-defined codes
namibianCulture.ThreeLetterISORegionName = "xna"; // I use x as 'extended' and 'na' as namibia
namibianCulture.TwoLetterISORegionName = "xn";
namibianCulture.ThreeLetterWindowsRegionName = namibianCulture.ThreeLetterISORegionName;
// see http://www.currency-iso.org/dl_iso_table_a1.xml
namibianCulture.ISOCurrencySymbol = "nad";
namibianCulture.CurrencyEnglishName = "Namibia Dollar";
namibianCulture.CurrencyNativeName = "Namibia Dollar"; // you may want to change this
// this is were you build something specific, like this symbol you need
namibianCulture.NumberFormat.CurrencySymbol = "N$";
// you'll need admin rights for this
namibianCulture.Register();
}
public static void UnregisterNamibianCulture()
{
CultureAndRegionInfoBuilder.Unregister("en-NA");
}
Once you have called the Register function once on a given machine (you will need to install this culture on end user machines), you can now use your initial WPF startup code, just change it like this:
System.Threading.Thread.CurrentThread.CurrentUICulture = new CultureInfo("en-NA");
And everything should work as expected. You can also use standard language tags and all that jazz, since en-NA is now recognized.
