Creates an Event object that contains specific information about ioError events. Event objects are passed as parameters to Event listeners.

Creates a copy of the IOErrorEvent object and sets the value of each property to match that of the original.

Returns a string that contains all the properties of the IOErrorEvent object. The string is in the following format:

[IOErrorEvent type= value bubbles= value cancelable= value text= value ]

Defines the value of the type property of an ioError event object.

This event has the following properties:

1. The class constructor creates a new instance of a URLLoader object and assigns it to the variable loader .
2. The URLLoader instance instantiates an event listener of type ioError , which has an associated subscriber method ioErrorHandler() , which simply prints information about the event using trace() .
3. Next, the constructor creates a new instance of a URLRequest object, request , passing MissingFile.xml so that the name and location of the missing file are known.
4. The request variable is then passed to loader.load() , which attempts to load the missing file. Since the file is missing, the event handler dispatches an ioError event.

Notes:

• You need to compile the SWF file with "Local Playback Security" set to "Access Local Files Only".
• Make sure that you do not have a file named "MissingFile.xml" at the same level as your SWF file.
