Access between classes

[Doug Chinnock]

I have several pointers to classes in the header file for MainDoc:
-----------------
class MainDoc : public CDocument
{
protected: // create from serialization only
MainDoc();
DECLARE_DYNCREATE(MainDoc)

// Attributes
public:
CAView* m_AView; // Set in AView:
CBView* m_BView; // Set in BView:
CCView* m_CView; // Set in CView:

// Operations
public:

I have several pointers to classes in the header file for MainDoc:

Are you sure it's not 'CMainDoc'?

{
protected: // create from serialization only
MainDoc();
DECLARE_DYNCREATE(MainDoc)

// Attributes
public:
CAView* m_AView; // Set in AView:
CBView* m_BView; // Set in BView:
CCView* m_CView; // Set in CView:

// Operations
public:
.
.
==========
These get initialized when the classes (of type CTreeView and CView) are
created:

Are you sure it's not 'MainDoc'? Seems in disagreement with the earlier
definition...

pDoc->m_AView = this;
==========
I can use these from classes CTreeView and CView:

This is not right (are you making it up as you go?), it probably is

pDoc->m_AView->...

==========
However when I try to use the same code from a CDialog class, I get the
error:

'GetDocument' is apparently a member of 'CTreeView' and 'CView' and _not_
a member of 'CDialog'.

=========

Is there a means of providing access to variables in MainDoc?

You need to request the address of your 'MainDoc' or 'CMainDoc' (whichever
is the correct one) and pass it to the function in 'CDialog' or wherever
you need it.

And if you'd like an audience that is familiar with (and willing to
discuss) MFC, try microsoft.public.vc.mfc
