All objects in the Visual Basic language have their own properties, methods, and events, including forms and controls. You can treat a property as an attribute of an object, treat a method as an action of an object, and treat an event as a response to an object.Objects in everyday life, such as helium balloons, also have properties, methods, and events. The properties of a balloon include the visible properties, such as its height, diameter, and color
