public dynamic class LoadVars
extends Object
The LoadVars class is an alternative to the loadVariables() function
for transferring variables between a Flash Lite and a web server
over HTTP. Use the LoadVars class to obtain verification of successful
data loading and to monitor download progress.
The LoadVars class lets you send all the variables in an object
to a specified URL and load all the variables at a specified URL
into an object. It also lets you send specific variables, rather
than all the variables, which can make your application more efficient.
Use the LoadVars.onLoad handler to ensure that your application runs
when data is loaded, and not before.
The LoadVars class works much like the XML class; it uses the
methods load(), send(), and sendAndLoad() to
communicate with a server. The main difference between the LoadVars
class and the XML class is that LoadVars transfers ActionScript
name and value pairs, rather than an XML DOM tree stored in the
XML object. The LoadVars class follows the same security restrictions
as the XML class.
