Resco Locker v1.30.2 for Palm

Resco Locker is

a utility that keeps applications locked in memory on NVFS systems. While Resco Locker can be formally used on non-NVFS systems, it cannot do anything usefull here.

Why to use Resco Locker?

Main reason is the safety. NVFS brought changes to the Palm OS programming and not all applications reflected them. (Those that were last time updated prior to NVFS release, could not.) One of the most frequent problems is that the Palm databases are no longer fixed. That's exactly the problem that is targeted by Resco Locker. For more detailed explanation of the NVFS specifics see please the discussion on the Resco Backup product page.

As a side effect, applications locked in memory need less time to load, which in turn may increase the performance of your handheld.

News

V1.01 - Locks the whole applications instead of just the first records.

V1.02 - corrects occasional bad display of the "L" attribute

V1.03 - another correction of the DB attribute "L" (locked).

V1.04 - preference panels added to the application list.

V1.05 - 5way handling added

V1.10 - Prevented locking of ROM DBs (crash), moving cursor by typing a char, support for DA's (Desk Accessories), sorting by the lock state

V1.20

• Palm TX compatibility
• Attribute "P" denotes protected databases.
• "!" marks apps that might be acting on background. (They receive typical notifications.)
• You can save DbCache space by locking the code segments only. (Concerns apps only.)
• DA's display DA launcher icon.
• Help.txt included into the .zip installer.

V1.21 - Bug fix: DB protecting limited to the Palm TX applications only

V1.30 Locking is compatible with the newest Palm models: T700p, T680.

Added the possibility to lock overlays that override some ROM database, i.e. RAM databases of the type 'ovly' which have a ROM DB with the same name/creator/type.

Purpose:
Under NVFS unlocked RAM overlays can be discarded from the DbCache and Palm OS may start using the original ROM file instead.

Usage

Lock
Select applications by tapping the respective rows and tap the Lock button. The locking is performed immediately.

Unlock
To unlock repeat the same procedure and tap the Unlock button.

Supplementary possibilities
Action trigger offers selection commands (e.g. Select All) and Column Setup dialog. (Additional columns are type, creator, date.)
To change the sort order tap suitable column label.

Meaning of attributes
! - Receives Notifications
L - Locked
O - Opened
B - Backup
P - Protected

General Options dialog:
Resco Locker can be disabled, in which case it unlocks all currently locked applications. (However, these apps will be further on marked as locked.)
Resco Locker can restore application locks on reset or clear all locks - depending on the option the user selects.

Typical use

1. Options dialog: Enable RLocker and switch on 'Only lock code'
2. Action trigger > Select Defaults
3. Unselect apps that you know are safe
4. Press Lock button
5. Test
6. If satisfactory, switch on 'Restore locks after reset' in the Options dialog
7. Otherwise read Help.txt (part of the .zip installer)

The risks

One could envisage specific programming constructs that under special occasions would conflict with external locking as performed by Resco Locker. These constructs are not very probable, but cannot be excluded either.

Conclusions

Resco Locker was created with the hope to help the users. However, Palm OS is an open system and bad interactions with the way RLocker works cannot be excluded. We don't want any money for this tool, but do not take any responsibility for eventual consequences. Use it with care.
