A class is a declarative description of a set of objects that all share the same procedures and have a similar set of variables and events. The members of such a set of objects are called instances of the class. A typical class may have multiple instances but VBA also allows the definition of classes that are restricted to having only one instance. All instances of a specific class share a common set of variable and event declarations that are provided by the class but each instance has its own unique set of variables and events corresponding to those declarations.
