Enum DeclarationRole

What a member of a class module is there for, when it is not there on its own account.

public enum DeclarationRole

Fields

EventHandler = 2: It handles an event of a WithEvents variable of the class module, by being named VariableName_EventName (MS-VBAL §5.3.1.8).
InterfaceImplementation = 1: It implements a member of an interface the class module Implements, by being named InterfaceName_MemberName (MS-VBAL §5.3.1.9).
None = 0: A member like any other, or one whose role the pass could not tell.
UnmatchedEventHandler = 3: It is named as the handler of an event of one of a form's controls (TextBox1_Change), and does not match the event: it is not a subroutine, or its parameter list is not compatible with the event's. MS-VBA compiles it, and the event never calls it: it is dead code, unless the module's own code calls it as the procedure it also is.
