API: Manipulate Access Window
Author(s)

(Q) How do I maximize or minimize the main Access Window from code?
(A) Pass one of the declared constants to the function fSetAccessWindow.
This same function can also be used to completely hide Access window and just show your form on the desktop. Make the form popup and from it's Open Event, call the fSetAccessWindow function with SW_HIDE as the argument.
Warning: If you're hiding the main Access window, make sure your error handlers are good. Because with the window hidden, if an error is raised, pressing "End" on the Error window will NOT make Access window visible and you will be left with just the form open. A recommended method is to make a call to fSetAccessWindow with SW_SHOWNORMAL from your error handlers.
If, for some reason, the Access window does not show itself, then you can always close the mdb from the Task List, available in Win 95 with Control-Alt-Delete (once) and under NT, by right clicking on the Taskbar and selecting Task Manager, by selecting the mdb and clicking End Task.
