Definitions globalization The process of designing and
implementing a product and/or content (including text and non-text
elements) so that it can accommodate any local market (locale).
localizability The ability of a product and/or content (including
text and non-text elements) to be adapted for any local market
(locale). localization The process of adapting a product and/or
content (including text and non-text elements) to meet the
language, cultural, and political expectations and/or requirements
of a specific local market (locale).

ASP.NET Mobile Controls - Overview set of ASP.NET controls in
Visual Studio.NET 2003 to create mobile web applications for Visual
Studio.NET 2002 known as Mobile Internet Toolkit broad support for
connected devices with browsers for: HTML xHTML (Basic and Mobile
Profile) WML (Wireless Markup Language) cHTML (compact HTML)
adaptive rendering

ASP.NET Mobile Controls Overview extensible and customizable
controls and adapters state management: application and session

ASP.NET Mobile Controls - Globalization internal character
encoding is Unicode support for character set conversion to and
from device character sets all controls are globalized display of
localized control strings and exceptions requires: installation of
a language pack (available in 21 languages) and/or Windows Server
2003 in the desired language
Slide 9
ASP.NET Mobile Controls - Globalization how to make your
application culture-aware: CultureInfo ci =
CultureInfo.CreateSpecificCulture(Request.UserLanguages[0]);
System.Threading.Thread.CurrentThread.CurrentCulture = ci;
System.Threading.Thread.CurrentThread.CurrentUICulture = ci;
handling device character sets: configure in web.config section
Content-Type:;charset=XXX overrides setting in configuration for
request encoding how to use Accept-Charset:
Response.ContentEncoding =
Encoding.GetEncoding(Request.Headers["Accept-
Charset"].ToString());
Slide 10
ASP.NET Mobile Controls - Localization how to localize
applications add resource files (.RESX) to your project create a
resource manager in Application_Start: ResourceManager LocRM = new
ResourceManager("LocProject.strings",
typeof(MobileWebForm1).Assembly); Application["rm"] = LocRM; use
the resource manager to load string resources in a form:
ResourceManager LocRM = (ResourceManager)Application["rm"];
this.Label1.Text = LocRM.GetString("txtLabel1"); alternatively
persist your resource manager in the session state

.NET Compact Framework - Overview lightweight version of
the.NET Framework designed for resource-constrained devices online
and offline supported by Visual Studio.NET 2003 two available
programming languages: Visual C#.NET Visual Basic.NET major areas
of.NET Compact Framework: base classes drawing/Windows Forms
data/XML XML Web Service Client supported devices: Pocket PC
2000/Pocket PC 2002/Pocket PC Phone Edition any device based on
Windows CE.NET 4.1 soon: Smartphone

.NET Compact Framework- Globalization globalization support in
System.Globalization culture support is factorized Pocket PC:
world-wide English+CJK Windows CE.NET: WWE+CJK+Rest of World uses
some data from underlying operating system (Windows CE): sort
tables character property tables code page conversion tables
CurrentCulture/CurrentUICulture are device-wide settings supports
calendars based on the Gregorian calendar
Slide 15
.NET Compact Framework- Globalization character encoding
internal character encoding is Unicode System.Text.Encoding
supports all codepages provided by operating system mlang.dll
character rendering fonts can be installed by application no
complex script support (including bidirectional languages)
conclusion: for connected applications convert data to
culture-invariant form before it reaches the device
Slide 16
.NET Compact Framework - Localization full support for
localization like in.NET Framework: class System.Resources support
for managing multiple language resources in Visual Studio.NET no
localized properties contained in the runtime managed exception
strings are available in 10 languages reduce memory requirements
for distribution using custom.CAB files emulator images in
different languages can be installed for testing
Windows CE.NET 4.1.NET Compact Framework 1.0 add-on
downloadable from the web customizing globalization support locale
support codepages fonts input methods (IME, handwriting
recognition, keyboard layouts) multi-lingual user interface
operating system resources available in 12 languages
