Every control on a form—every text box, every label, and every check box—has a set of properties that you can modify. A property is an attribute that defines an object's appearance, behavior, or characteristics. For example, the properties of a house would be its color, square footage, and shape. A property for a field on a form might be the number of decimal places displayed or the default value for the field. Because you can almost always change an object's properties, you can think of them as the object's settings.
