Hello all.

The new CMFCListCtrl class, included with the VC9's feature pack, is
cool. I wanted to use it for my CListView's instead of the old one.
After some research, I saw that there was nothing I could to to replace
old CListCtrl with CMFCListCtrl in the view. So I decided to create my
own view.

I was planning on deriving a class from CCtrlView (CListView's parent
BTW) and while researching, I came across an article by Tom Archer[1].
In this article, he explains how to do this. He suggest that one should
specify in the CCtrlView's first parameter the name of the window's class.

So, I thought that such thing would be an easy way to solve my problem.
I thus spy++'ed and discovered that CMFCListCtrl's class name is
"SysListView32", the same for the CListCtrl I want to avoid. Or course,
I should have noted that CMFCListCtrl will only override some message
handling to do the cool stuff it does.

So now my question is, is there any way I can do what I want deriving
from CCtrlView (perhaps I'm missing something)? Or should I go one step
further and instead derive from CView and handle all the resizing, etc,
by myself?



Ah, never mind. I already derived it from CView, what the hell. It was
easy anyway. So, here's the code in case someone is interested.

// mfclistview.h

#pragma once

class CMFCListView : public CView

     virtual ~CMFCListView();

     CMFCListCtrl& GetListCtrl();

     virtual int OnCreate(LPCREATESTRUCT lpcs);
     virtual void OnSize(UINT nType, int cx, int cy);
     virtual void OnDraw(CDC* pDC);

     virtual void InitList();

     CMFCListCtrl m_wndListCtrl;

// mfclistview.cpp

#include "stdafx.h"
#include "mfclistview.h"



   : CView()


int CMFCListView::OnCreate(LPCREATESTRUCT lpcs)
   DWORD dwStyle;
   BOOL bResult;

   bResult = CView::OnCreate(lpcs) == -1;
   if (bResult == -1) return bResult;

   bResult = m_wndListCtrl.Create(dwStyle, CRect(0, 0, 0, 0),
               this, 1);

   return bResult ? 0 : -1;

void CMFCListView::OnSize(UINT nType, int cx, int cy)
   CView::OnSize(nType, cx, cy);

   if (::IsWindow(m_wndListCtrl))
     m_wndListCtrl.MoveWindow(0, 0, cx, cy, TRUE);

void CMFCListView::OnDraw(CDC* pDC)

void CMFCListView::InitList()

CMFCListCtrl& CMFCListView::GetListCtrl()
   return m_wndListCtrl;
