Raised event sorting which wasnt handled




















In both cases, you can use the AddHandler statement to handle those events. WithEvents variables allow a single event handler to handle one or more kind of event, or one or more event handlers to handle the same kind of event. Although the Handles clause is the standard way of associating an event with an event handler, it is limited to associating events with event handlers at compile time. In some cases, such as with events associated with forms or controls, Visual Basic automatically stubs out an empty event handler and associates it with an event.

For example, when you double-click a command button on a form in design mode, Visual Basic creates an empty event handler and a WithEvents variable for the command button, as in the following code:. The AddHandler statement is similar to the Handles clause in that both allow you to specify an event handler. However, AddHandler , used with RemoveHandler , provides greater flexibility than the Handles clause, allowing you to dynamically add, remove, and change the event handler associated with an event.

If you want to handle shared events or events from a structure, you must use AddHandler. AddHandler takes two arguments: the name of an event from an event sender such as a control, and an expression that evaluates to a delegate. You do not need to explicitly specify the delegate class when using AddHandler , since the AddressOf statement always returns a reference to the delegate.

The following example associates an event handler with an event raised by an object:. RemoveHandler , which disconnects an event from an event handler, uses the same syntax as AddHandler. For example:. In the following example, an event handler is associated with an event, and the event is raised. The event handler catches the event and displays a message. Then the first event handler is removed and a different event handler is associated with the event.
