different language words are associated withthe key so u 
call the key and select the language then the key will 
automatically select its value.

Create resource files for each language.. u want to dispaly 
on the website.(add+new item+resource file)

now create instance for resourcemanager class and set its 
path.

set the string(u want to convert) to the resource manager.

now panel1.innerhtml=resourcemanager1.string;

and so on...
