Remarks

When you create an Verify event, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate.
Delegates are similar to the function pointers of C++ and have two main uses: performing callbacks, and defining events. Delegates are defined at run time.

Callback methods allow asynchronous processing: the method being called starts a thread and returns, during which time the thread does most of the work and calls the callback only when needed.
Events use a publish and subscribe type pattern. A class 'publishes' an event and any number of classes can 'subscribe' to that event. The runtime notifies subscribers when an event occurs. Delegates that are used in defining events must be defined as taking two arguments: a publisher object, and an event information object (derived from the .NET EventArgs class).

Requirements

Target Platforms: Microsoft .NET Framework 3.0, Windows XP, Windows Server 2003 family, Windows Server 2008 family
