Hi Friends,
This question is specfic to M125 device Security Application. I am
developing a customized application which should go to sleep mode when the
user presses the ON/OFF switch. If the user had set a PASSWORD, the device
should prompt for password, irrespective of whichever application the user
is working in, when the user switches ON the device back.
The problem i am facing is, the application displays an error message which
I have given below, whenever the notification fires and tries to display the
LOCKDEVICE2FORM.
ERROR MESSAGE:
===============
"Applications" 4.0 reports "MemoryMgr.c, Line 4365, NULL handle". If
this is the latest version
of "Applications", please report this to the application author.
If I press CONTINUE to the message, the error message2 is displayed
which says the application
had performed a Bus error.
I am using :
PalmOS40-efigs-color.rom
Palm OS Emulator 3.0a8.
Palm OS version 3.5
Could someone please help me on this. Thanks a lot. Regards
Yuva
