Re: searching for a contact in the phonebook

[Michael]

I need to lookup a contact in the Treo 650 address book when my application is 
launched from a launch code other than sysAppLaunchCmdNormalLaunch. The code 
from this post(see below) works great when my app is running from a 
sysAppLaunchCmdNormalLaunch, but otherwise the line:

err = SysAppLaunchSysAppLaunch(cardNo, dbID, 0, sysAppLaunchCmdNotify, 
(MemPtr)&params, &result); 

results in a crash:
datamgr.c, Line:8898, DmWrite:DmWriteCheck failed.

The next time I call the app (even from the normal launch code) results in a 
BadDBRef error, crashing the Treo650 simulator. Does anyone know what is 
causing this problem or if there is another way to access phone book contacts 
that I can try to work around this? (BTW if I run this on the phone it appears 
to work correctly)

thanks, Michael
