例

次のコード例では、 オブジェクトを MenuCommand 作成し、そのプロパティを構成して、 オブジェクトに IMenuCommandService 追加します。

   public ref class CDesigner: public ComponentDesigner
   {
   public:
    [PermissionSetAttribute(SecurityAction::Demand, Name="FullTrust")]
      virtual void Initialize( IComponent^ comp ) override
      {
         ComponentDesigner::Initialize( comp );
         IMenuCommandService^ mcs = static_cast<IMenuCommandService^>(comp->Site->GetService( IMenuCommandService::typeid ));
         MenuCommand^ mc = gcnew MenuCommand( gcnew EventHandler( this, &CDesigner::OnF1Help ),StandardCommands::F1Help );
         mc->Enabled = true;
         mc->Visible = true;
         mc->Supported = true;
         mcs->AddCommand( mc );
         System::Windows::Forms::MessageBox::Show( "Initialize() has been invoked." );
      }

   private:
      void OnF1Help( Object^ /*sender*/, EventArgs^ /*e*/ )
      {
         System::Windows::Forms::MessageBox::Show( "F1Help has been invoked." );
      }
   };
}

public class CDesigner : System.ComponentModel.Design.ComponentDesigner 
{
    public override void Initialize(IComponent comp) 
    {
        base.Initialize(comp);

        IMenuCommandService mcs = (IMenuCommandService)comp.Site.
                    GetService(typeof(IMenuCommandService));
        MenuCommand mc = new MenuCommand(new EventHandler(OnF1Help), StandardCommands.F1Help);
        mc.Enabled = true;
        mc.Visible = true;
        mc.Supported = true;
        mcs.AddCommand(mc);
        System.Windows.Forms.MessageBox.Show("Initialize() has been invoked.");
    }

    private void OnF1Help(object sender, EventArgs e) 
    {
        System.Windows.Forms.MessageBox.Show("F1Help has been invoked.");
    }
}

<System.Security.Permissions.PermissionSetAttribute(System.Security.Permissions.SecurityAction.Demand, Name:="FullTrust")> _
Public Class CDesigner
    Inherits System.ComponentModel.Design.ComponentDesigner

    Public Overrides Sub Initialize(ByVal comp As IComponent)
        MyBase.Initialize(comp)

        Dim mcs As IMenuCommandService = CType(comp.Site.GetService(GetType(IMenuCommandService)), IMenuCommandService)
        Dim mc As New MenuCommand(New EventHandler(AddressOf OnF1Help), StandardCommands.F1Help)
        mc.Enabled = True
        mc.Visible = True
        mc.Supported = True
        mcs.AddCommand(mc)
        System.Windows.Forms.MessageBox.Show("Initialize() has been invoked.")
    End Sub

    Private Sub OnF1Help(ByVal sender As Object, ByVal e As EventArgs)
        System.Windows.Forms.MessageBox.Show("F1Help has been invoked.")
    End Sub
End Class
