Can anyone tell me how to programmatically turn the task bar "off" (& back
on again), so I can have a maximized window come up full screen?

This doesn't "turn off" the taskbar, but it does hide it behind your window:
---- untested code starts here ----
include win32lib.ew
-- use the WinAPI to get the screen resolution in pixels
constant screenCX = c_func(xGetSystemMetrics,{SM_CXSCREEN})
constant screenCY = c_func(xGetSystemMetrics,{SM_CYSCREEN})
-- now create the window
constant MainWin = create(Window,"Big Winder",0,0,0,screenCX,screenCY,0)
----------------------
--- your code here ---
----------------------
WinMain(MainWin, Normal)
---- end code ----
Also, if you want to hide the caption bar with the -0X buttons in the upper
right hand corner, you can of course use the WS_POPUP window style.
Go to bed!

Thanks Brian,
I was already using " getExtent(Window1)" to help center things in my
window, & I remember now that you remind me having seen SystemMetrics used
before somewhere, but it didn't occur to me to try that to make a fully big
window. Thanks!

You can also use:
screenSize = getExtent( Screen )
keep in mind that the user can resize the screen while an application is
running.

Thanks Brian & David,
Some interesting things about both ideas for covering up the task bar:
1. Brian used the "Normal" parameter in WinMain, & because I already had
"Maximize" there in my code, I left it like that; mistake, it HAS to be
"Normal" to work;
2. If I run it while connected to Internet, the window won't stay big; it
starts out big, but then the screen flickers with other window's stuff & the
task bar comes back (not a problem for me, since mine isn't an Internet app,
but could be a problem for those that are);
3. If the window IS resized, RESTORING it DOESN'T re-coverup the task bar
(I'll probably use Brian's suggestion & use WS_POPUP to eliminate the
buttons that would allow that, since it also denies manual resizing; gotta
remember to provide way to CLOSE it, with buttons gone!)

Has anyone considered telling windoze to hide the taskbar with a win_msg?
Naturally, i don't know if that setting can be changed without rebooting,
but since clicking on the desktop makes the taskbar collapse, i'd guess
there is some msg to tell it to collapse once that's enabled.
Kat,
just musing.

Kat,
That does sound like a better way, if it would work, although I haven't the
foggiest idea how to do so :) , and Brian & Dave's suggestions worked ok
for me, in case I didn't make that clear; I just thought I'd mention the
caveats I noticed in case anyone else tried to use them in an Internet app.
But clicking on my desktop doesn't collapse my taskbar !?

Yeas, i saw that, but the thing is, clicking on any app collapses the
taskbar, once the taskbar loses focus it drops down off the desktop,, that
includes internet apps. If i have an Eu app running a windoze window and a
dos window, clicking on either drops the taskbar. If the app already has
focus, the taskbar drops on it's own when the mouse leaves it.

Do you have "Hide Taskbar" enabled? Naturally, with windoze, it's in the
Start menu, under Settings.

9. Re: how turn off task bar
Dan,
Just to save a lot of back and forth, I believe that Kat is referring to what
happens to the task bar when autohide is turned on in the taskbar properties
dialog. The problem with that is that many other events can bring the task
bar back without your permission. Your program would have to check and/or
turn on that property, and then send it a message to go away. I'm not sure
what you would have to do to be notified every time the task bar wanted to
come back. I can't comment on the rest.

10. Re: how turn off task bar
I have not been following this thread, but after a quick search on the MSDN
knowledge base, I came up with the following:
It is aimed at VBA, but by the looks of the API calls, it could be easily
adapted.

Nick,
That looks like exactly what I was looking for, except for the small matter
of the statement:
"Advanced: Requires expert coding, interoperability, and multiuser skills.
",
which unquestionably is NOT me :(
I'll probably just stick with trying to cover the taskbar up with a POPUP
window, but thanks for finding the info.
