Problem "using namespace ..." [message #882170]

I am writing a class in C++ in which I am using the following namespaces:
using namespace System;
using namespace System::ComponentModel::Container;
using namespace System::ComponentModel;
using namespace System::Windows;
using namespace System::Windows::Forms;
using namespace std;

However, Eclipse is saying that there are errors for all of these namespaces, even std, which is in many classes. I tried debugging but it did not help. Can someone please tell me how to fix this?

Did you select the correct toolchain in Project Properties?
Project Properties->Index->Rebuild
if still shows errors
Project Properties->Index->Show unresolved includes

I need more info to help you.
