Re: Multiple program versions

[Huiqiang Zhang]

Did you changed the program's CreatorID or TypeID? Normally if a new version 
of a program is installed, and it has the same TypeID as the old version 
program which still exist in the device, then the Palm OS will replace the 
old version of the program. So if you make all the versions of your program 
always with the same TypeID and CreatorID, everything will be OK!

Subject: Multiple program versions


I've got some users that are getting lock-up errors on
their Palms while running my program.  A typical error
says Memory manager, null pointer, press reset.  It
seems random and I can't recreate it.  This has
happened after they've upgraded to the latest version
of the program.  Is it possible some fragments of the
old program are still there?  If there's a program
myprog_v1.0.prc loaded, and I send them
myprog_v1.1.prc, and they load it, then version 1.1
gets installed, but in the program
files\palm\user\backup directory, BOTH prc files are
there.  The next time they do a hard reset, are both
going to be loaded?  Could this be causing a problem?
Thanks.
