Contoh

Contoh kode berikut menyediakan metode yang melampirkan penanganan aktivitas untuk ComponentsCreated peristiwa ToolboxItem. Ini juga menyediakan ToolboxComponentsCreatedEventHandler metode penanganan aktivitas yang menulis nama jenis komponen yang dibuat ke Console ketika penanganan aktivitas dinaikkan oleh peristiwa ComponentsCreated .

public:
   [PermissionSetAttribute(SecurityAction::Demand, Name="FullTrust")]
   void LinkToolboxComponentsCreatedEvent( ToolboxItem^ item )
   {
      item->ComponentsCreated +=
         gcnew ToolboxComponentsCreatedEventHandler( this, &Form1::OnComponentsCreated );
   }

private:
   void OnComponentsCreated( Object^ sender, ToolboxComponentsCreatedEventArgs^ e )
   {
      // Lists created components on the Console.
      for ( int i = 0; i < e->Components->Length; i++ )
      {
         Console::WriteLine( "Component #" + i + ": " +
            e->Components[ i ]->Site->Name );
      }
   }

public void LinkToolboxComponentsCreatedEvent(ToolboxItem item)
{
    item.ComponentsCreated += new ToolboxComponentsCreatedEventHandler(this.OnComponentsCreated);
}

private void OnComponentsCreated(object sender, ToolboxComponentsCreatedEventArgs e)
{
    // Lists created components on the Console.
    for( int i=0; i< e.Components.Length; i++ )
        Console.WriteLine("Component #"+i.ToString()+": "+e.Components[i].Site.Name.ToString());            
}

Public Sub LinkToolboxComponentsCreatedEvent(ByVal item As ToolboxItem)
    AddHandler item.ComponentsCreated, AddressOf Me.OnComponentsCreated
End Sub

Private Sub OnComponentsCreated(ByVal sender As Object, ByVal e As ToolboxComponentsCreatedEventArgs)
    ' Lists created components on the Console.
    Dim i As Integer
    For i = 0 To e.Components.Length - 1
        Console.WriteLine(("Component #" + i.ToString() + ": " + e.Components(i).Site.Name.ToString()))
    Next i
End Sub
