﻿tx=You can use the LoadVars class to obtain verification of successful data loading and to monitor download progress. The LoadVars class is an alternative to the loadVariables() function for transferring variables between a Flash application and a server. 
The LoadVars class lets you send all the variables in an object to a specified URL and to load all the variables at a specified URL into an object. It also lets you send specific variables, rather than all variables, which can make your application more efficient. You can 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 load(), send(), and sendAndLoad() methods 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 Document Object Model (DOM) tree stored in the XML object. The LoadVars class follows the same security restrictions as the XML class.
