Represents a method that handles a change in an item's access path.

[Visual Basic]
 Public Delegate Sub  ClientHandleChangeDelegate( _
   ByVal sender As Object, _
   ByVal oldHandle As Integer, _
   ByVal newHandle As Integer _
)
[C#]
 public class ClientHandleChangeDelegate(
   object sender,
   int oldHandle,
   int newHandle
);
[C++]
 public __gc class ClientHandleChangeDelegate(
   Object* sender,
   int oldHandle,
   int newHandle
);

[JScript] In JScript, you can use the delegates in the .NET Framework, but you cannot define your own.

Parameters [Visual Basic, C#, C++]

The declaration of your event handler must have the same parameters as the ClientHandleChangeDelegate delegate declaration.

sender

The source of the event.

oldHandle

The previous handle of the item.

newHandle

The new handle of the item.

Remarks

When you create an ClientHandleChangeDelegate delegate, 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. For more information about event handler delegates, see Events and Delegates.
