Your alarm handler won't be in an event loop, but the application that is running when your alarm triggers is still running and still needs an appStopEvent. So, use SysUIAppSwitch. > What should I pass as the cmdPBP argument? NULL? Yes. > When the volume is unmounted, I should delete start.prc from the main > memory. How do I do that? There are two problems. You should watch for the app quitting (it's a notification), and only delete the app on volume unmount after you've noticed that the app has quit. > How do I *find* the start.prc in the main memory anyway?

Use the database name; it's unique to the device. -- Dave Carrigan Seattle, WA, USA [EMAIL PROTECTED] | http://www.rudedog.org/ | ICQ:161669680 UNIX-Apache-Perl-Linux-Firewalls-LDAP-C-C++-DNS-PalmOS-PostgreSQL-MySQL -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
