CFormView-like Modeless Dialog

Hi All,

Is there any way to create a window with all of the attributes of CFormView
WITHOUT having to create a CFormView.  I really don't need the document
class for this app, but I would like a scrollable, dialog-based MDI window.  

I've tried:

1. Modeless dialog: not MDI
2. CMDIChildWnd with the dialog resource created in it: background painting
needs to be handled, no scrolling.

Any other ideas?  Or did I just not go far enough with #2?

Steve

I think CFormView gives you _exactly_ what you want.  CFormView does
not require a document.  Just set the CDocument pointer to NULL, or if
you are using CMultiDocTemplate, the document CRuntimeClass pointer to
NULL.  Voila, a CFormView without a document.  Works great.  I use it
all the time.

    You could try CFormView as a child of CMDIChildWnd (giving it the ID
of AFX_IDW_PANE_FIRST):

CMyChildWnd::OnCreate(...)
{
    CFormView* pDlgWnd = new CFormView;
    pDlgWnd->Create(...);
    // etc, etc...
}

I know you said you don't want to create a CFormView, but you can create and use CView without 
a document.  The framework will shoot out a warning that you're creating a view without a 
document, but it doesn't seem to harm anything.  Mind you, I've discovered this from fooling 
around, I've never tried to write a serious app using this technique.  Basically, what you'd 
do is:

  CChildFrame *pFrm = new CChildFrame;  // CChildFrame is a CMDIChildWnd
  CCreateContext Cx;
  Cx.m_pNewViewClass = RUNTIME_CLASS(CMyView);
  Cx.m_pCurrentDoc = NULL;
  Cx.m_pNewDocTemplate = NULL;
  Cx.m_pLastView = NULL;
  Cx.m_pCurrentFrame = pFrm; // This may be unnecessary - I think it can safely be NULL
  pFrm->LoadFrame(IDR_NOTEMPTYPE, WS_OVERLAPPEDWINDOW | FWS_ADDTOTITLE,
    m_pMainWnd,&Cx);

Option #2 is a possibility, but there's so much code in CScrollView that would have to be 
duplicated that I'd pursue trying to use the view some more.  After all, "You are not a 
machine, so stop repeating yourself" ;)
