Doc-View Architechture

I have an application (MDI) built over the document-view type of architecture of MFC. I have the following problems.
how ....
To get a pointer to an application object from document class?
To get a pointer to a frame window object from document class?

2. Regarding to CMDIChldWnd
To get a pointer to an application object from frame window class ?
To get a pointer to a document template object from frame window class?
To get a pointer to a document object from frame window class?GetActiveDocument()?
To get a pointer to a view object from frame window class? GetActiveView()?
3. Regarding to CView Class
To get a pointer to a document template object from CView class?
To get a pointer to an application object from CView class ?

Since I have two types of frameworks in my Application how can i access one from the other?
Waiting for a reply,
Thanks in advance
