Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnChanged
method also enables derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Note
Functions and objects in the Microsoft.VisualBasic.Compatibility.VB6 namespace are provided for use by the tools for upgrading from Visual Basic 6.0 to Visual Basic. In most cases, these functions and objects duplicate functionality that you can find in other namespaces in the .NET Framework. They are necessary only when the Visual Basic 6.0 code model differs significantly from the .NET Framework implementation.
When overriding OnChanged
in a derived class, make sure to call the OnChanged
method of the base class so that registered delegates receive the event.
