Extending MFC Applications with the .NET Framework

Wrapping MFC Objects for Remoting

One serious limitation when using remoting is that you cannot remote MFC objects across application domains. Consider the following two classes that we can attempt to remote:

namespace SecondDll
{
  public __gc class StrWrapper : public MarshalByRefObject
  {
  public:
    StrWrapper(CStringArray* list)
    {
      m_list = list;
    }
    CStringArray* m_list;
  };


  public __gc class WebList : public MarshalByRefObject
  {
  private:
    CStringArray* m_list;
  public:
    WebList()
    {
      m_list = new CStringArray();
      m_list->Add(S"Amazon");
      m_list->Add(S"Rediff");
      m_list->Add(S"Yahoo");
      m_list->Add(S"Google");
    }
    ~WebList()
    {
      delete m_list;
    }
    CStringArray* GetList()
    {
      return m_list;
    }
    StrWrapper* GetList2()
    {
      return new StrWrapper(m_list);
    }
  };

}

Essentially ...
