*Number of languages = number of txt file
Base name=abc
culture name=en region name=us
abc.en-us.txt

# After making txt files, convert them to resource file
abc.en-us.resources
abc.fr-be.resources
abc.de-at.resources
# Resources file = compressed (common bitmap, icon, images, common string)
# Open Visual Studio and Make new Project
*Website >
Add new Item > Text file > abc.en-us.txt
b= Hello
c= English

Globalization – culture specific classes
Threading
– multi-threading concept
#Global Application Class
- one project one file- to manage application and session level events
#Website > Add new Item > Global Application
Class
<%@ Application Language="C#" %>
<%@ Import Namespace="System.Globalization"%>
<%@ Import Namespace="System.Resources"%>
<%@ Import Namespace="System.Threading" %>

void Application_Start(object sender, EventArgs e)
-
fire at first and one time only when
project runs
void Application_Start(object sender, EventArgs e)
{
// Code that runs on application
startup
Application["rm"] =
ResourceManager.CreateFileBasedResourceManager("abc", Server.MapPath("."), null);
}
|
Rm= Global Variable (can be used in whole project)
. = current path
Null = current resource setting
# Make new method to fire the event everytime when request is send to server
void Application_BeginRequest(object sender,
EventArgs e)
{
try
{
Thread.CurrentThread.CurrentCulture = new
CultureInfo(Request.UserLanguages[0].ToString());
}
catch
{
Thread.CurrentThread.CurrentCulture = new
CultureInfo("en-us");
}
Thread.CurrentThread.CurrentUICulture =
Thread.CurrentThread.CurrentCulture;
}

Application_BeginRequest-
Number of times is request send to server , the event should be fired same
number of time
try,
catch – Structure error
