Filter listbox with toggle button

[livin''''life]

I am sure this is a simple solution but i cant seem to get it. What i have
is a form with a list box that displays names of personnel. What i would
like to have happen is this:
When the form opens, all personnel are listed in the listbox (which already
works) and then i would like a toggle button on the form that will filter the
listbox when it is pressed. The control for the filter will be a yes/no box
and i would only like to see the personnel with 'yes' checked.

Thank you for your help.
