   unsigned short WideCharBuffer[100];
   int BufferLength = 100;

   try
   {
      PtrIMXNamespaceManager.CreateInstance( _
                              __uuidof(MSXML2::MXNamespaceManager));
      PtrIMXNamespaceManager->declarePrefix(_T("sample"),_T("urn"));
      
      hres = PtrIMXNamespaceManager->_getURI(L"sample", NULL, _
                                             WideCharBuffer, _
                                             &BufferLength);
      DisplayMessageToUser(_bstr_t(WideCharBuffer));

      PtrIMXNamespaceManager->pushContext();

      PtrIMXNamespaceManager->declarePrefix(_T("sample"),_T("urn2"));
      
      BufferLength = 100;
      hres = PtrIMXNamespaceManager->_getURI(L"sample", _
                                             NULL, _
                                             WideCharBuffer, _
                                             &BufferLength);
      DisplayMessageToUser(_bstr_t(WideCharBuffer));

      PtrIMXNamespaceManager->popContext();

      BufferLength = 100;
      hres = PtrIMXNamespaceManager->_getURI(L"sample", _
                                             NULL, _
                                             WideCharBuffer, _
                                             &BufferLength);
      DisplayMessageToUser(_bstr_t(WideCharBuffer));
   }
   catch(...)
   {
      DisplayMessageToUser("Error");
   }
}

void DisplayMessageToUser(char *Msg)
{
   ::MessageBox(NULL, Msg, _T("Message"), MB_OK);
}

Remarks

The pushContext method pushes the local context down the stack, and creates a new local context.
