- trigger the update in 4D, to send the message to all connected user
(4D code)
-- the above trigger starts a timer event/deamon which eventually
shuts down the server
- in the On Shut Down database method, use LEP to trigger a .bat file
which copies the need files.
-- the new files will need to be in a specific location, and so will
the server replacement files
- to trigger the .bat file there are a couple of options (links below)
to setup a timed task (probably 2 .bat files one that creates the
scheduled task to execute the 2nd to do the actual copy.
- in the batch file that does the copy you *should* be able to launch
the 4D app again too.
