[AccessD] How To Make All Controls on a Form Invisible

All,

We have an Access 2007 application that has a form which contains many
controls (buttons).

This application is now going to be placed on a PC where the user is
only suppose to see only 1 button.

Is there an easy way in VBA to make all buttons on the form invisible.
(This would be followed by a single line of code to make the single
button visible for this specific user.)

Thanks,
Brad
