To run the sample from command line use - vbc /out:Event.exe Event.vb Imports System Public Class CTimer Delegate Sub SecondDel ( ByVal xintTime As Integer ) Private evtSecond As SecondDel Public Event evtMinute As SecondDel Public Event evtHour ( ByVal xHour As Integer ) public Shared lngSeconds As Long Public Sub Register ( ByVal objSecond As SecondDel ) evtSecond = evtSecond. Another class CClock is defined that has members to handle the RaisedEvents from CTimer class.

The class also provides mechanism to register event and raises events with intervals simulating 5, 10 and 30 units of the interval. The example shown declares a delegate in class CTimer and also declares three events in the class using all the aforementioned declarations.

The event is raised by making a call to RaiseEvent.ĭeclaring a sub and either attaching it to the delegate or registering with the event declaring class can handle the event. The event is implemented by using implicitly declared delegate by the framework. Public Event evtSample(Cancel as Boolean) - event handler procedure would be registered by using Handles keyword in the declaration itself. The event is raised by making a call to RaiseEvent. The event is implemented by using the above-declared delegate. Public Event evtSample as sampleDel - event handler can be registered by using AddHandler method in the Class that would provide the Handler. The event is raised by making a call to evtSample. The event is implemented by using explicitly declared delegate. Delegate can be declared as Delegate Sub sampleDel ( ByVal Cancel As Boolean )Īny method that has same signature can be attached to this delegate procedure that would have the same signature can handle this event.ĮvtSample As sampleDel - mechanism to register the event handler for this type of declaration is to be provided by the class declaring the event. Delegate class has signature, and it can hold references only to methods that match its signature.

Handle the event by declaring an event receiver, often called event handler, which is a subroutine that responds to the event.ĭelegate is a class that can hold reference to a method.

Declare the event signature using Event keyword and raise the event using RaiseEvent statement.

NET Framework would provide a default delegate implementation

Declare a delegate, if definition is not provided the.

Implementation of an event is a three-step procedure A delegate can reference both static and instance methods. Delegates are type-safe Function Pointers or Callbacks. NET Framework are based on the delegate model.
