You missed FrmPopupForm() (which I prefer to frmDoDialog()).
In the normal course of events, when you're popup is done you
use FrmReturnToForm() to go back where you came from. Your
form does -not- get a frmCloseEvent in this case. BUT -- if your
app is switched, your form -does- get a frmCloseEvent, so I implement
the cleanup code in a subroutine that is called both when I get a
frmCloseEvent
or if somebody presses the button that ends up invoking FrmReturnToForm().
I -presume- that something similar could be done for FrmDoDialog(),
that is I would guess that it will get a frmCloseEvent under these
circumstances. Perhaps somebody else could confirm this?
