I think you're also asking how to have your form display full screen, am I correct? You simply have to play around sizing it until you get it to over the screen! This will take a little bit of diddling, but it does create a nice Visual Basic like program effect. I use it frequently, as I find that non-power users (my end users are mainly medical professionals) are intimidated by the Access environment. Rather than having to go roaming thru the various pulldown menus looking for a task they need to perform, I provide them with custom buttons for just those functions they need.
The only caveat to using full screen forms is that sooner or later some user (maybe even yourself) will buy a new machine, and its default Screen Resolution will be higher than the one you developed your db on. This will, in effect, "shrink" your form so that it's not "full screen" anymore. The answer to this is an custom function to "resize" the screen to match the new resolution. Fortunately, someone has already done the work for you! Go to this site and scroll down to the "Access Form Resizer" and download it. I've used it before without problems, and best of all, it's FREE!
