Subject: Re: ActiveX and MVP: Implementation Strategies Redux

Hello Blair,

I went to the link you gave and printed the reply you gave to Ingo.
Your
answer to him is most helpful. We're happy to know that the approach
we
were taking before posting this question agrees with the approach that
you,
yourself, prefer: option (3).

Just as a follow-on to that other post concerning the Codejock ActiveX
error,
we are exploring the debugger in more detail to see how you got out of
it
everything that you put into your reply. And, rather serendipitously,
we
just came upon the Kent Beck Debugger Approach (if I may give it that
title)
described in the Ted Bracht's book.

So it would seems things are coming together rather well. As my
grandfather
would say, if we were to fall of the top of a building, we'd fall into
a
new suit of clothes.

Cheers,

Eric

Hello Forum,

This morning we purchased Codejock's ActiveX Suite (after having
given it a trial run over the last 30 days), and just 10 hours
later
we have pretty much brought up our application's Home Page (Dolphin
truly is remarkable!). Codejock's controls flawlessly imitate all
of
the controls that can be found in Microsoft Office, so in looking
at
our Home Page, you would think you were looking at an
MS-Outlook-in-progress!

Chris Uppal pointed us in the right direction with respect to
incorporating ActiveX into MVP, but now, after having studied the
examples and bringing up our Home Page, we have some deeper
questions
concerning the incorporation of ActiveX into the MVP scheme.

1. Why does MaskedEdit show up as a descendant of
AXValueConvertingControlSite, while URLPresenter does not? We're
having
trouble understanding why some views would stand on their own,
without a
Presenter, whereas others are contained in a Presenter. It would
seem
that MaskedEdit _is_ an AXValueConvertingControlSite while
URLPresenter
simply contains one. Is this just a granularity issue, where
perhaps
OA
has decided to build up the web browser control a bit for us?
2. As you all know, MS Outlook has what is typically called a
"shortcut
bar" on the left. Codejock has a control called XtremeShortcutBar
which
duplicates this control. Further, MS Office has in general what
are
called "command bars," which embraces both the toolbars and the
menu
bars,
and so Codejock has a control called XtremeCommandBars which
implements
these as well. We'll be using them instead of Dolphin's Toolbar
and
Menu.
Is it fair to say that some ActiveX controls would require the full
MVP
implementation, while others may require only a some part of it?
Since
the XtremeShortcutBar will be bound to underlying data (Model), by
its
specification allow user manipulation (Presenter), and by its
specification have a GUI interface (View), are we correct to assume
that
this control would implement full MVP? The XtremeCommandBars, on
the
other hand (in fact, menus and toolbars in general), don't seem
like
they
should have a Model, but do seem to have a Presenter and a View.
So
are
we correct to assume only partial MVP in this case?
3. Dolphin's online help, the technical paper "Twisting the Triad,"
and Ted Bracht's book have all been excellent tools in
understanding
MVP. But is there a decision tree out there for determining which
components of the triad should be implemented? Or is it an
all-or-nothing affair?

I've written a fair bit on this before. I know that Mikael Svane
brought together a nice summary of this, but although it can still
be
found in Google, the actual site seems to have disappeared.

This might help though as it gives guidance on the options and some
rules of thumb as to when to use each:
