I know very little about Palm OS (and my frequent posts will testify on that). I know nothing of the alarm system.
But I do know that passing a pointer to a local function variable is never good unless you use it before the stack frame returns from that local function. If the call to SysUIAppSwitch() just does something and then returns, and assuming you have nothing that keeps the execution in the same function, the variable autoUpdateParams will be taken off the stack and therefore any pointer to it will be invalid. I may be way off here, but a red light always comes on in my head every time a pointer to a local variable. Forgive me if I'm wrong. 2008/1/31, Oleg Ignatov <[EMAIL PROTECTED]>: > > Hello All. > I have some trouble with passing data to my application. > I set alarm for my specific needs. > Then from any applications I recieve this alarm notification and if my app > is not activated call: > > SysAutoUpdateDataParamType autoUpdateParams; > autoUpdateParams.ref = someParam; > SysUIAppSwitch(cardNo, dbID, sysAppLaunchCmd_AutoUpdateData, > &autoUpdateParams); > > passing parameters in the forth arg. > But when I recieve sysAppLaunchCmd_AutoUpdateData sublunch code and try to > retrieve parameters from the parameter block: > > UInt32 cmdPBPRef = ((SysAutoUpdateDataParamType*)cmdPBP)->ref; > > I have got some garbage instead my someParam. > What do I do incorrectly? > > Thanks in advance. > > ___________________ > Oleg Ignatov > > -- > For information on using the ACCESS Developer Forums, or to unsubscribe, > please see http://www.access-company.com/developers/forums/ > > -- For information on using the ACCESS Developer Forums, or to unsubscribe, please see http://www.access-company.com/developers/forums/
