Directing auto save to VB's command SAVE button function

This form maintains the attendees of a class. I have a table which contains
the data on the attendees from the division I work for. The classes are
being opened to attendees from other divisions.

The form was originally designed to be called from another form which
brought forward identifying data (Name, ID number and when they started our
program).
I now need to enter this form directly since I do not have the date these
other attendees entered the program and I do not want to put in the outside
attendees into our clients' table.

Using VB code I have accomplished the above PROVIDED the user remembers to
use the SAVE command button. If they don't use that button and exit or add a
new attendee, Access does an automatic save and all kinds of things happen,
including one computer actually locking up (although I think the user just
did not wait long enough before rebooting).

Question: Is there any way to force the automatic save to use your command
save function?
