Hi - we run an access application in our office. The database is split with the back end on a machine that also has a front end. There are two other machines with front ends - three users who access and manipulate the back end. When I make changes to the front end code from time to time, I merely change the name of the file to accdr, and this .accdr file replaces the previous .accdr file on the three machines. Even though the system runs smoothly, I'm wondering if should I be compiling my code when I make changes? I've read references to the fact that if code isn't compiled, it has to be compiled each time an uncompiled procedure is run. Is that true? Some advice from someone in the know would be great, thanks.
