I have a real big problem in my cdev. I hope that someone will say,
"Pete, you dope. This is simple. You forgot the semi-colon." Whatever...

I have a routine that updates a resource according to what's in an
editText box in my cdev. I call the routine when the OK button is
hit and when the cdev gets closed. On the hitDev, everything works
just ducky. I call the routine, passing it CPDialog, a handle to my
data (I do it the old fashioned way), and numItems. I check each to
make sure they have valid values entering the routine. They are all
constant on entering. Then I do a GetDItem for the editText box.
Boom. The value returned in the item Handle when I am on the hitDev
is some longword. On the closeDev, I get a 0. Now, I don't know for
sure that all the values in CPDialog and my data handle are correct
(doing that in Macsbug would've been ugly), but I am sure numItems
has not changed and the actual value of CPDialog and my data handle
are perfectly constant. Do the dialog items disappear before the
closeDev (that would be very bad, and unlikely since I have seen other
cdevs check data on the close), or am I doing something stupid?

If you would like to see actual code, I would be willing to trim down
to a small non-working piece and send it to you. Any help would be
*greatly* appreciated.

Thanks,
pr
