ActionScript 2.0 Language Reference - Adobe Help and Support

Returns
Boolean - false if no parameter (null) is passed; true otherwise. Use the onLoad() event
handler to check the success of loaded data.
Example
The following code defines an onLoad handler function that signals when data is returned to
the Flash application from a server-side PHP script, and then loads the data in passvars.php.
var my_lv:LoadVars = new LoadVars();
my_lv.onLoad = function(success:Boolean) {
if (success) {
trace(this.toString());
} else {
trace("Error loading/parsing LoadVars.");
}
};
my_lv.load("http://www.helpexamples.com/flash/params.txt");
For another example, see the Flash Samples page at www.adobe.com/go/learn_fl_samples.
Download and decompress the Samples zip file and go to the
ActionScript2.0\DataIntegration\Guestbook folder to access the guestbook.fla file.

public loaded : Boolean
A Boolean value that indicates whether a load or sendAndLoad operation has completed,
undefined by default. When a LoadVars.load() or LoadVars.sendAndLoad() operation is
started, the loaded property is set to false; when the operation completes, the loaded
property is set to true. If the operation has not completed or has failed with an error, the
loaded property remains set to false.
This property is similar to the XML.loadedproperty.
Availability: ActionScript 1.0; Flash Player 6
Example
The following example loads a text file and displays information in the Output panel when
the operation completes.
