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 errorID=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.
