Is it possible?

I tried it once but was unsuccessful. I created two classes: one from CListCtrl and the other from CListView. Maybe if I had dinked around with it for a few more hours, I could have made it work.

Just guessing, but since both inherit from CWnd, there are going to be some messages that will be sent to you twice and one is for the CListView and the other is for the CListCtrl. Not too sure if you will be able to differentiate what has to be done.
If you don't mind me asking, what might you be trying to accomplish?

It's a CE SDI app that displays multiple views. Two of the views are not associated with the doc, and they both contain a list control (derived from CListCtrl), but the views are not derived from CListView. I'm having problems getting the list control to show up in the view.
Most of the code is being ported from a desktop (MDI) version of the same app.

Here's a suggestion, but I have no familiarity with MFC on the CE development platform. Could each of the views be dialog based and the CListCtrl members of the dialogs?

I was trying to avoid that, but it would probably work.

Wouldn't that defaut the purpose of using a CListView? Keeping in mind that both classes are encapsulations of the Windows SysListView32 window class with the main difference being that the CListView has ties to the doc/view architecture, I would think that you would be losing what you're going after by simply using a CListCtrl on a dialog.

I don't need the doc/view interface for this view. It simply shows a list of files in a specific folder.

I'm confused here. The list view *is* the list control. A common misconception is that the list view contains an embedded list control. It doesn't. Both are CWnd that encapsulate the SysListView32 window. When you say the listview doesn't show up, what exactly are you seeing. Are you sure your view is in the correct mode (e.g., LVS_REPORT)?

I'm seeing an empty view. The listctrl is set to report mode, but i don't see the list control header.

I gotta tell you. The only things I can think of are the basics like did you insert the column headers (InsertColumn) and such. Other than that, I've never heard of such a problem. Also, are you setting the report view in the view's PreCreateWindow?

I think I need to start this again. The desktop app (legacy code, not coded by me) does this:
A CView-derived class that contains a data member that is defines as follows:
protected:<br />
CMyListCtrl< CDataObject > myListCtrl;<br />
A CListCtrl-derived class implemented like so:
<br />
template < class T > class CMyListCtrl : public CListCtrl<br />
{<br />
blah blah blah<br />
};<br />
The list control class cannot be changed because it's used in several other places (other views and dialogs as well).
I am probably mistaken, but this arrangement doesn't appear to me to be usable as far as deriving new view classes. Would it be valid to do this:
typedef CMyListCtrl< CDataObject > CMyDataObjectListCtrl;<br />
and then use the new typedef as a basis for using your CCtrlView article (cited by someone else)?
<br />
CMyListView::CMyListView():CCtrlView(_T("MYLISTCTRL"), AFX_WS_DEFAULT_VIEW) { };<br />
<br />
CMyDataObjectListCtrl& CMyListView::GetListBox() const <br />
{ return *(CMyDataObjectListCtrl*)this; }<br />

No promises, but I'm seeing if I can get my demo to work with a derived CListCtrl class right now.

Just in case you didn't know, the demo project is no longer available from the developer.com web site article.

I don't think it's what you're looking for anyway. My article's intention is to illustrate how to create a CCtrlView-derived class that uses any Windows class. It's not intended to use an already-coded derived CWnd class. I'm seeing what I can do with it, but I might have to revert to Zafir's kludge.

I'm in the middle of negotiating with a new client, but I'll work on this as time permits.

Zafir did something similiar years ago with the CTreeCtrl and CTreeView. Check out CodeGuru. It's not 100% the same, but I did get his to work at one point when working with listview/listctrl so I know it can be done.
Sorry to not be more specific. But it's definitely not trivial and at least will point you in the right direction.

Ok Tom, I know this is off the subject here, but does anyone know what happened to Zafir? What is he doing now?

Pretty much disappeared from the Internet altogether huh? I guess I find that a little odd when it looks like he initially contributed so much, not to say others didn't.

I know what you mean, but everyone is different. Obviously the main thing he cared about was the $$. Out of the millions he made on the site, Maunder and I asked that he give a small amount to the various section heads. We're talking maybe 10k here - not something unreasonable for the peopl that made him rich. He never even responded and eventually just disappeared.

This is the only way I've been able to use a derived CListCtrl with a view in the past. However, I just tried to use it and it 1) doesn't compile without some tweaks and 2) asserts all over the place.

I'm thinking your only choice is something very manual, where you use a FormView, subclass the list control with your derived class and then manually handle sizing issues.
