WithEvents (Visual Basic)

Specifies that one or more declared member variables refer to an instance of a class that can raise events.

Comentários

When a variable is defined using WithEvents, you can declaratively specify that a method handles the variable's events using the Handles keyword.

You can use WithEvents only at class or module level. This means the declaration context for a WithEvents variable must be a class or module and cannot be a source file, namespace, structure, or procedure.

You cannot use WithEvents on a structure member.

You can declare only individual variables—not arrays—with WithEvents.

Rules
