----------------------------------------------------------- From: Jigs Message 1 in Discussion Hi Niyati, NET, defines a delegate as a class that holds a reference to a method oEssentially a typesafe callback method reference (pointer) In Vb.NET you can define delegate as Public Delegate Sub MyCallbackHandler(x as integer) The signature of the delegate defines the signature of the methods it can call. For example, the MyCallbackHandler delegate shown above can be used to refer to void methods that take a single integer as a parameter: Delegate Tutorial: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/csref/html/vcwlkDelegatesTutorial.asp and Events are declared as Public Event MyCallbackEvent As MyCallbackHandler Events can be used to inform an object that something significant has happened, and interrupt the flow of control in that object causing it to execute a method designed for handling the event. An event provides a component with a hook that an interested client can attach one of its methods to. When the component wants to indicate that something significant has happened, it can raise the event and consequently call the associated methods Events are closely related to delegates, and rely on the functionality of multicast delegates for registering methods to be called when an event is raised Events Tutorial : http://msdn.microsoft.com/library/default.asp?url=/library/en-us/csref/html/vcwlkEventsTutorial.asp Regards, Jignesh Desai http://www.dotnetjiNi.com ----------------------------------------------------------- To stop getting this e-mail, or change how often it arrives, go to your E-mail Settings. http://groups.msn.com/MumbaiUserGroup/_emailsettings.msnw Need help?
