Hi,
I am writing a HyperCard XCMD to use popup menus from resources
(I didn't like the idea of creating the data structures each and
every time I invoked the thing). I pass the menu id to the XCMD,
and then I do a GetMenu on the id, then go through that menu looking
for submenus, and call GetMenu on them.
This works (so far), and it returns the proper values. After I use the
menus, I call DeleteMenu on them (also recursively) to take them out
of the list of active menus.
After I am finished with the menus, I make them purgeable again, then
return.
My problem:
In Inside Mac I, it claims that GetMenu should never be called more than
once for a menu. Yet I have to call GetMenu each time I invoke this
XCMD; however, I do a DeleteMenu for each menu I call GetMenu for.
My question:
Even though this SEEMS to be working, am I creating a time bomb?
Thanks,

"(For menus read from a resource file with GetMenu, use ...Release- Resource instead [of DisposeMenu]" (I-352) Which means that if you want to torch a menu from the menu bar and memory you have to first DeleteMenu and then ReleaseResource (in your case). The Menu Mgr is usually pretty flexible but I couldn't get Get/Set- ItemCmd to work for me using normal command keys. I suspect they only work for hier-menus but maybe I'm holucinating. I found a work around anyway (no need to reply). / Josh Pritikin T Ignorance is bliss. \ | Internet: 6500stom@ucsbuxa.ucsb.edu | I must be in hell. | | AppleLink: Josh.P | My room is proof that entropi | \ GEnie: J.Pritikin ! exists. /
