Question about OCX's and toolbars, menubars, statusbars

Hi folks,
I have a question about writing OCX's. I'm trying to convert
an MFC application into an OCX, and the first thing I'm trying to do
is get a toolbar and statusbar to appear in the control. I ran 4.2's
control wizard to get a vanilla control. In the MFC app, the toolbar
and status bar are created in the OnCreate. What trick do I need to do
to get them to appear in the control?
Are there any guidelines (function mappings, or something) comparing
MFC app's to OCX's?
Does anyone have any sample source, or pointers to sample source, which
do what I'm trying to do?
Thanks very much,
David Dworkin

David,
I think you are a little confused about the function of an OCX. An OCX is not a
runnable program, it is a control that you put on a dialog box. Read in the
Visual C++ manual about the usage of a OLE custom Control.

Hi Michael,
I'm familiar with what an OCX is. Just because an OCX can be as simple
as a button or another windows control, that doesn't imply that they
are all that simple.
I guess more specifically, I'm trying to write an ActiveX control, which
encapsulates the functionality of an MFC application, and which would be
contained within a web page.
Any tips, tricks, advice, black magic, etc from anyone would be appreciated.
David

No: some controls can be impressively robust. But a control is a
_CONTROL_. It is not a form or a dialog box or an application.

I think you might want to consider having a collection of ActiveX controls
rather than just one single control. It really depends on your user interface,
though--there are some applications that could be made into a single control,
while others (most, probably) just can't be conveniently held in a single
control.

David,
My company is using complex OCXs as a major part of our development
strategy.
We are using the OCX controls to encapsulate the whole User interface
aspect of our application (Using context menus instead of top-of-window menus).
In this way we are able to do almost everything.
If the control is OLE insertable, it can even behave as a standard OLE object.
What specific MFC application functionality are you looking for?

Hi David,
I am probably not going to answer your exact question, but I am going to try
to give you an alternative.
First, ActiveX controls can be "contained within a web page" as you ask,
withOUT any special modifications! To me this is really the exciting part of
what OLE is all about, the fact that new technology can always use the same
old technology.
Now as far as your original question about converting an MFC app to an OCX
control so you can contain it within a web page, it appears to me that you
might want to take a look at ActiveX Documents (DocObjects). DocObjects, are
the "Server" side of an MS Office Binder, and IE30 incorporates much the same
function. Basically, you can view all those control bars etc that you want
within IE3O. It's cool stuff.
I think the online docs in www.microsoft.com can better explain what they are
all about.
C ya,
Mike Massa

You are really on a futile course. The reason is that MFC applications are
designed to be document/view. OCX's are are view only, thus all the cool
functionality of menu bars, etc are not supported. Menu's are supposed to
be merged with the containers menus, the control itself is not (and cannot,
becuase it is not a top level window) supposed to have it's own menus.
What you might investigate, however, is ActiveX Documents Objects. These
are variations on the In-Place active theme designed to work with MS Office
Binder and Internet Explorer 3 (or any Doc object container).
There is an example in VC 4.1 and 4.2 called bindscrib, 4.1 hacked doc
object support in, 4.2 has it native in MFC.
