I can't figure it out. :-((
OK, so I tried a different approach. Instead of going to the proper form and
running the event loop when I get a notification, I decided to launch myself
with a custom launch code:
UInt32 PilotMain (UInt16 cmd, MemPtr cmdPBP, UInt16 launchFlags)
{
UInt16 cardNo;
LocalID dbID;
UInt32 romVersion;
switch (cmd)
{
case sysAppLaunchCmdNormalLaunch:
case sysAppLaunchCmdCustomBase + 1:
AppStart ();
FrmGotoForm ((cmd == sysAppLaunchCmdNormalLaunch) ? kMainForm :
kScanningMemoryCardForm);
AppEventLoop ();
AppStop ();
break;
case sysAppLaunchCmdSystemReset:
case sysAppLaunchCmdSyncNotify:
FtrGet (sysFtrCreator, sysFtrNumROMVersion, &romVersion);
if (romVersion >= version40)
SysNotifyRegister (cardNo, dbID, sysNotifyVolumeMountedEvent,
NULL, sysNotifyNormalPriority, NULL);
break;
case sysAppLaunchCmdNotify:
HandleNotification ((SysNotifyParamType *) cmdPBP);
break;
default:
break;
}
return 0;
}
void HandleNotification (SysNotifyParamType *np)
{
DmSearchStateType stateInfo;
UInt16 cardNo;
LocalID dbID;
switch (np->notifyType)
{
case sysNotifyVolumeMountedEvent:
DmGetNextDatabaseByTypeCreator (true, &stateInfo, 'appl',
appCreatorID, true, &cardNo, &dbID);
SysUIAppSwitch (cardNo, dbID, sysAppLaunchCmdCustomBase + 1, NULL);
break;
default:
break;
}
}
This doesn't crash. However:
1) When installed on the simulator and when the simulator is reset, my
application is started and it scans the memory card *twice*. Why twice?! OK,
currently I don't check which volume is being mounted and scan all the
available volumes. So, if a device had more than one card and both were mounted
on reset, my program would be run twice. However, the Tungsten E simulator with
HostFS does not have two cards; it has only one! And why the previous version
(that tried to do a FrmGotoForm) was run only once, implying that there is only
a single volume mounting event at reset??
2) When used on a real device, it doesn't crash, either. However, the card is
*not* scanned when it is inserted in the slot! Instead, the Launcher does its
usual thing - plays a sound, displays the applications in /PALM/Launcher, etc.
It's as if my application isn't getting a volume mounted event notification.
Why?!
And, if I reset the real device with the card left in the slot, my application
*is* launched - and scans the card. Once, not twice.
This thing is driving me nuts... :-((( Help?

Vesselin
