CmfcDoc* CFrontEnd::GetDocument() const
{
//      ASSERT(m_pDocument->IsKindOf(RUNTIME_CLASS(CmfcDoc)));
      return (CmfcDoc*)m_pDocument;
}

CmfcDoc* pDoc=(CmfcDoc*) GetDocument();

I wanna get some data items from CDoument class while not from CView class, how do I achieve this? Thanks
Jack

From any place of CView-derived class you can use GetDocument function to access the document class:

void CFrontEnd::AnyFunction()
{
    GetDocument()->SomeFunction();  // access document functions and members
}

From any place if SDI application you can access document class by the following way:

CMainFrame *pFrame = (CMainFrame*)AfxGetApp()->m_pMainWnd;
CMyView *pView = (CMyView *) pFrame->GetActiveView();
CMyDocument* pDocument = pView->GetDocument();
