AddHandler Statement
Associates an event with an event handler at run time.
Syntax
AddHandler event, AddressOf eventhandler
Parts
event
The name of the event to handle.
eventhandler
The name of a procedure that handles the event.
Remarks
The AddHandler and RemoveHandler statements allow you to start and stop event handling at any time during program execution.
The signature of the eventhandler procedure must match the signature of the event event.
The Handles keyword and the AddHandler statement both allow you to specify that particular procedures handle particular events, but there are differences. The AddHandler statement connects procedures to events at run time. Use the Handles keyword when defining a procedure to specify that it handles a particular event. For more information, see Handles.
[!NOTE] For custom events, the
AddHandlerstatement invokes the event'sAddHandleraccessor. For more information on custom events, see Event Statement.
