Cześć wszystkim.
Mam aplikację w Windows Forms, C++/CLI. Jest trochę klas, w jednym z okienek (nie głównym) chciałem dokonać konwersji z typu String^ do typu string, z tego, co znalazłem, można do tego użyć metody marshall_as, której przykład znaleźć można tutaj -> http://msdn.microsoft.com/en-us/library/bb384859%28v=vs.100%29.aspx .
Gdy chcę do swojego okienka, konkretne pliku utworz_postac.h dołączyć bibliotekę oraz przestrzeń nazw zgodnie z przykładem z MSDN (poniżej zawartość początku tego pliku):
#pragma once
#include <msclr\marshal.h>
namespace Gra_RPG {
using namespace std;
using namespace System;
using namespace msclr::interop;
using namespace System::ComponentModel;
using namespace System::Collections;
using namespace System::Windows::Forms;
using namespace System::Data;
using namespace System::Drawing;
Dostaję takie błędy kompilacji:

Zresztą, nawet bez tej przestrzeni nazw using namespace msclr::interop; dostaję te same błędy. Dodam, że znajomy robi podobny program i u niego działa to bez zarzutów, używa tego samego środowiska - Visual Studio 2010.
Co może być przyczyną?
