I am wondering if there is a way to disable the "X" used to close the
Access application window? I know how to disable it for individual
forms, but I would like to disable it for the application in general
and force users to use a button on the switchboard to close (because I
run important code on the close of the database from that button).
Any ideas are always appreciated.
Thanks!
Paste the following code into a standard module.
In a startup form use -
fActivateCloseBox(False)
You can play around with the other functions to remove max/min buttons and the
control box.
