An 'event' is an action recognized by an object, such as clicking a mouse or pressing a key, and you can write code to respond to that event. You can change an object's characteristics by changing it's properties. In Visual Basic, you might say that a radio has a 'Volume' property that you can adjust by changing its value. Assume you can set the volume of a radio from 0 to 10. In addition to properties, objects have methods.
Methods are part of objects just as properties are.
Generally, methods are actions you want to perform, while properties are the attributes you set or retrieve. For example, you dial a telephone to make a call. Dial 3334444 Objects also have events. Events are triggered when some aspect of the object is changed. For example, a radio might have a 'VolumeChange' event.
