Guys,
sorry it not make sense to you. I knew it was a difficult question to ask.
But had to do the following to get it to work:

BOOL CSystemFrame::Create()
{
    ASSERT(mSysDoc == NULL);
    // TODO: Add your specialized code here and/or call the base class
    CCreateContext context;
    context.m_pNewViewClass=RUNTIME_CLASS(CSystemTreeView);
    mSysDoc = new CSysDoc();

    context.m_pCurrentDoc = mSysDoc;

    return CMDIChildWnd::Create(NULL, _T("System Configuration"), WS_CHILD |
WS_VISIBLE | WS_OVERLAPPEDWINDOW,
                                rectDefault, NULL,&context);
}

And then it all works... So needed to create my own context as this gets
passed into the splitter etc and then i needed to do the following

    CView* pView = (CView*)m_wndSplitter.GetPane(0,1);
    ASSERT_VALID(pView);
    ASSERT_VALID(pView->GetDocument());
    pView->SendMessage(WM_INITIALUPDATE);

    pView = (CView*)m_wndSplitter.GetPane(0,0);
    ASSERT_VALID(pView);
    ASSERT_VALID(pView->GetDocument());
    pView->SendMessage(WM_INITIALUPDATE);

Inside

BOOL CSystemFrame::OnCreateClient(LPCREATESTRUCT /*lpcs*/, CCreateContext*
pContext)

Hope this makes sense now?

I don't understand. If you have your own MDIChildFrame, that's fine. You would use this
frame class in your document template.

This would be created with the normal mechanisms; you don't have to use a File>New menu
item to create a document, you can just invoke the creation mechanism of the template.

Here's the code I use to do this:

CDocument * CFontExplorerApp::NewItem(CMultiDocTemplate * templ)
    {
     CDocument * doc = templ->CreateNewDocument();
     ASSERT(doc != NULL);
     if(doc == NULL)
        return NULL;

     CFrameWnd * frame = templ->CreateNewFrame(doc, NULL);
     if(frame == NULL)
        { /* failed to create */
         delete doc;
         return NULL;
        } /* failed to create */

     templ->InitialUpdateFrame(frame, doc, TRUE);
     return doc;
    } // CFontExplorerApp::NewItem

How can i manually add my own CDocument derivative to a CView deriative?

I have created my own MDIChildFrame with a splitter a two formviews and want
each to share the same document.

So this document does not get created via the usual file new procedure or
doc template stuff.

I cannot find an easy way to set the document of each view?
