Příklady

Následující příklad ukazuje registraci ComponentRenameEventHandler a a manipulaci s ComponentRename událostí.The following example demonstrates registering a ComponentRenameEventHandler and handling the ComponentRename event.

public:
   void LinkComponentRenameEvent( IComponentChangeService^ changeService )
   {
      // Registers an event handler for the ComponentRename event.
      changeService->ComponentRename += gcnew ComponentRenameEventHandler(
         this, &ComponentRenameEventHandlerExample::OnComponentRename );
   }

private:
   void OnComponentRename( Object^ /*sender*/, ComponentRenameEventArgs^ e )
   {
      // Displayss component renamed information on the console.
      Console::WriteLine( "Type of the component that has been renamed: " +
         e->Component->GetType()->FullName );
      Console::WriteLine( "New name of the component that has been renamed: " +
         e->NewName );
      Console::WriteLine( "Old name of the component that has been renamed: " +
         e->OldName );
   }
public void LinkComponentRenameEvent(IComponentChangeService changeService)
{
    // Registers an event handler for the ComponentRename event.
    changeService.ComponentRename += new ComponentRenameEventHandler(this.OnComponentRename);            
}

private void OnComponentRename(object sender, ComponentRenameEventArgs e)
{
    // Displayss component renamed information on the console.           
    Console.WriteLine("Type of the component that has been renamed: "+e.Component.GetType().FullName);                  
    Console.WriteLine("New name of the component that has been renamed: "+e.NewName);
    Console.WriteLine("Old name of the component that has been renamed: "+e.OldName);
}
Public Sub LinkComponentRenameEvent(ByVal changeService As IComponentChangeService)
    ' Registers an event handler for the ComponentRename event.
    AddHandler changeService.ComponentRename, AddressOf Me.OnComponentRename
End Sub

Private Sub OnComponentRename(ByVal sender As Object, ByVal e As ComponentRenameEventArgs)
    ' Displays component renamed information on the console.           
    Console.WriteLine(("Type of the component that has been renamed: " + e.Component.GetType().FullName))
    Console.WriteLine(("New name of the component that has been renamed: " + e.NewName))
    Console.WriteLine(("Old name of the component that has been renamed: " + e.OldName))
End Sub

Poznámky

Při vytváření ComponentRenameEventHandler delegáta identifikujete metodu, která událost zpracuje.When you create a ComponentRenameEventHandler delegate, you identify the method that will handle the event. Chcete-li přidružit událost k obslužné rutině události, přidejte do události instanci delegáta.To associate the event with your event handler, add an instance of the delegate to the event. Obslužná rutina události je volána při každém výskytu události, dokud neodeberete delegáta.The event handler is called whenever the event occurs, unless you remove the delegate. Další informace o delegátech obslužných rutin událostí naleznete v tématu manipulace a vyvolávání událostí.For more information about event-handler delegates, see Handling and Raising Events.
