No, you can also actually hide the Access window, you have to search for apiShowWindow function. I'm not going to describe it, it's available on MSDN and on the Access Web.
For the method to work the calling form must be in both MODAL and POPUP mode.
The only drawback: once hidden, none of the Access objects appear in the taskbar (but can be closed from the Task Manager by ending the Access process). So they suggest having strong Error Handlers, all of which also restore the Access window so it doesn't stay hidden.
On my form I have a check box (hide/show Access).
I did notice an interesting feature, though: When I first change the form from nonModal and nonPopup to Modal and Popup (in design view) and then run it, when I click to hide the Access Window, both Access and the Form appear in the Windows Task bar. I am now trying to come up with code that would force that "event" every time. That way it would be a very classy way of designing applications - user's don't even see Access, only the App screen and they can switch to other programs and back.
I also have a Quit App button on my form (obviously) so that the users can close application (and Access).
I wonder if this is an undocumented, unintended feature in Access 2000 and maybe it could become a real feature. It sure is useful.
