Well, I fixed the error - I moved the
FrmGetActiveForm() call to inside the case, rather
than just inside the switch, and everything's hunky
dory... so while I try to figure out why DmNewRecord's
doing stuff w/ low memory, can anyone explain why I
was getting that error message to begin with? I'm not
changing the form I'm using, I just changed the code
from:
switch(...)
{
frmP=FrmGetActiveForm();
to
switch(...)
{
case xyz:
frmP=FrmGetActiveForm();
(And if you have any ideas why DmNewRecord is dealing
w/ low memory, feel free to pass that on as well...)
Thanks :-)
