| | If the event handler is called by the onsubmit attribute of the form object, the code must explicitly request the return value using the return function, and the event handler must provide an explicit return value for each possible code path in the event handler function. | | | Although event handlers in the DHTML Object Model do not receive parameters directly, a handler can query an event object for data. | | | This example shows how to use onsubmit on a form to request the return value using the return function. |

| | Understanding Delegates in Visual Basic .NET |
| | Delegates and a stronger event programming model required that event handlers have arguments, and sanity justified a polymorphic means of implementing event handlers. | | | From Chapter 8, you know that an event is an occurrence in your program, and an event handler is a procedure defined to respond to that occurrence. | | | For example, Quit might prompt the user to make sure he or she wanted to exit not only the current context but the entire program, whereas the more deliberate File, Exit might suggest that the user is clear about his or her intentions and definitely wants to exit the application. |
