I opened the Contact Web database template.  Form Main has a hyperlink, 
actually a command button that looks like a huperlinl, that has the 
caption "Configuring The Database".

The macro for the OnClick event sets a tempvar callec tmpVideo and sets 
the value to a hyperlink.  It then "BrowsesTo" a form called VideoPlayer 
and has the path as
   Main.NavigationSubform>GettingStarted.sfrVideo

If I open form Main in LayoutView (there's no design view), open the 
property sheet, I can select NavigationSubform from the dropdown list of 
controls.  There is no form "NavigationSubform".

There is a form however called "Getting Started" that matches the tab 
GettingStarted in form Main.  May I assume NavigationSubform is an 
object tab that was created from a Navigation form and then renamed?

In form GettingStarted there is a subform with the name sfrVideo and the 
control source Default Image.  The form DefaultImage doesn't seem to be 
anything more than a Play button.  The image itself has the macro call'
   Main.NavigationSubform>GettingStarted.sfrVideo

There are buttons that keep popping up on the forms while in layout mode 
that have tiny crosses in square boxes.  I suppose that button indicates 
a subforms but that's just guessing.  I wonder if there's a help topic 
that covers icons...you know, the icon on the left, description on the 
right?  I can't find one.

Anyway, DefaultImage plays the value of the form VideoPlayer.  But I 
don't see the form VideoPlayer on the GettingStarted form.  How does 
VideoPlayer overlay DefaultImage.

I'm not sure why there are so many subforms.  In the past these might 
have simply been controls on a form.  Perhaps all the splitting up is to 
demonstratene features or perhaps make it work with the web?

The above path looks correct. We have the top form called Main. Then we =
have
navcontorl called NavigationSubform. The browse to command "object" is
simply the name of the form in the navigation buttons we wan to work on.
(that nav button will become active if it is not).

NavigationSubform is the standard name of the sub form that used in all
navigation forms. In fact as a general rule, NavigationSubform is the=20
default name.
(so you could rename it, but it was not). Fire up a client application =
and=20
create
a nav form, and then bring I up in design view (as opposed to layout =
view),=20
you
will see the same defaulted sub form.

As always, remember a sub form is not really a form, but in fact just a=20
control
on a form (of which we can set the source object).

Ignoring that web forms use the new layout mode (introduced in 2007), =
those
sub forms do not work really any different then how Access and sub forms
in the past worked. In fact, the only real change here is a sub form =
control=20
can
now display a report (and this works for client VBA applications also). =
So
a navigation form is really just a set of buttons and then ONE sub form
called NavigationSubForm. You could change the name, but for coding
consistancity, I would not.

Sure, since we can set the "sourceobject" of what will display in a =
subform,
this is a nice easy way to have a image change occur. We just switch
the sub form from one that displays a image with a click event to one
that has a web control to the internet to display that view.

>  The image itself has the macro call'
>   Main.NavigationSubform>GettingStarted.sfrVideo

The above is correct. The way the browseto command works is you specify
which object on the nav pane you want to switch. I don't have time to
give a great explain here, and I simply have to get some sleep.
Once you played with the browseto command a few times, then it all makes =

sense.

In this case it somewhat more complex since we are setting the source =
object=20
of a subform
inside of a subform.

No, the little + or cross hair means you are using a layout control. As=20
noted, these were introduced in a2007, and they help huge in reports and =

forms for layouts.
I will say that in a web form, since you have to use layout view, then =
they=20
are not as helpful.

The answer is in your next question:

>I'm not sure why there are so many subforms.  In the past these might
>have simply been controls on a form.  Perhaps all the splitting up is =
to
>demonstratene features or perhaps make it work with the web?

No, they do not really have that many sub forms. However, to flip from =
that=20
image with a play button click, they simply  flip the source object of a =
sub=20
form to one with a web control that displays the video. And the web url =
is a=20
tempvar, so they can display any video they want with that sub form. I =
mean=20
in place of open form, we just changing what displays in a single sub =
form.

We really only have:

Main form -> NavagationSubform ->sfrVideo

So, that is only 2 subform controls here.

So we just flip the sub form sfrVideo (we change the source object) =
between=20
a form called DefaultImage and Video player.

So, while we have a few forms, we only changing and dealing with one sub =

form called sfrVideo

Even before a2010 and the nav control, we often see people switch the =
source=20
object of a control to change what displays in that sub form.

In web based systems, you really do not want to launch a separate =
browser=20
window since then you loose all control of where the user will return =
when=20
they close that new browser session. So, by flipping the sub form, the =
user=20
stays inside of the same form and therefore inside of the same browser. =
I=20
mean, 5 browsers open, which forms belong to yahoo and which belong to =
your=20
application? (you loose control real fast). So, keeping things inside of =
a=20
form is much recommended for web applications.

I should re-write that browseto command as a an VBA example as to how =
the=20
source object of the sub form is being changed, and then this would be =
more=20
clear.

I guess I am finding/determining what is and what is not a subform in 
layout view a bit difficult.  Web databases, near as I can make out, 
don't have any design view.

Just finding the form's property sheet seems to be a lesson in trial and 
error.  Click, check the property sheet, click elsewhere, check the 
property sheet, and someday you get to the main form's property sheet 
and not some navigation subform.  It's easy enough to determine a 
control like a command button.  Finding the form's property sheet isn't.

I kinda wish there was Intellysis for entering the path.

I'll have to lookup what a layout control is.  As I mentioned earlier, 
without any design mode for web layouts, finding a form, subform, and 
perhaps a control can be a pain.

I wish the Contacts database was done both in Regular and Web so one can 
spot what's going on easier.

Thanks for your input.
