C++ managed class issue

Hi I've create a C++ managed Class as :

*.h file
#pragma once

#include "afxcmn.h"
using namespace System::Design;
using namespace System::Drawing::Design;
using namespace System::ComponentModel;
using namespace System::ComponentModel::Design;

namespace VXP_Editors
ref class VXP_ColumnEditor : public

and *.cpp file
#include "stdafx.h"

#include "VXP_ColumnEditor.h"

namespace VXP_Editors
#pragma region VXP_ColumnEditor

#pragma endregion
when i compile it, VC++.NET displays errors :

l:\editors\VXP_ColumnEditor.h(5) : error C2039: 'Design' : is not a
member of 'System'
l:\editors\VXP_ColumnEditor.h(5) : error C2871: 'Design' : a namespace
with this name does not exist
l:\editors\VXP_ColumnEditor.h(13) : error C2039: 'CollectionEditor' : is
not a member of 'System::ComponentModel::Design'
l:\editors\VXP_ColumnEditor.h(13) : error C2504: 'CollectionEditor' :
base class undefined

how is it possible ?
in my project property options, i add the references to the right
thx for help.
