请问我这样来来获得CATIContainer 。但为什么总是说<<"error getting the spConODocs"<< 呢。以前这样做是可以的，现在怎么又不行了呢。

CATIContainer *DialogCommand::pSpecContainer(void)
{
CATFrmEditor* pEditor = CATFrmEditor::GetCurrentEditor();
  if(!pEditor)
   {
         cout <<"error getting the FRM editor"<< endl;
   return NULL;
   }
CATDocument *pDoc = pEditor->GetDocument();
  if(!pDoc )
   {
         cout <<"error getting the CATDocument"<< endl;
return  NULL;
}
CATIContainerOfDocument_var  spConODocs = NULL_var;
HRESULT rc = pDoc->QueryInterface(IID_CATIContainerOfDocument,(void**)&spConODocs) ;
   if(!spConODocs)
   {
         cout <<"error getting the spConODocs"<< endl;
         return NULL;
   }
CATIContainer* pSpecContainer = NULL;
HRESULT hr = spConODocs->GetSpecContainer(pSpecContainer);
spConODocs->Release();
if(pSpecContainer == NULL_var)
   {
         cout <<"error getting the pSpecContainer"<< endl;
   }
  if(spConODocs == NULL_var)
   {
   cout <<"error getting the container of documents"<< endl;
   }
return pSpecContainer;
}
