What is the "KEY" to PersistantStore?
I have a few apps I did today and saved data (objects) in the store persistent using the regular:
_persist.setContents( objectname ); _persist.commit();
and to load using the following:
Options opt = new Options(); _persist = PersistentStore.getPersistentObject( PERSIST ); opt = (Options)_persist.getContents(); if (opt == null) { opt = new Options(); _persist.setContents( opt ); _persist.commit(); }
My question is:
I use the button "next" (or whatever it's called)...
private static PersistentObject _persist; private static final long PERSIST = 0x9dbb6535e730ff3dL;
Now, when I have several app using the same 'KEY', the object saves because of course, they will be of different objects, so I've just been arbitrially by changing the 'key' to something new PERSIST, not really knowing what it means / fact.
Actually, I guess that this could be a major problem since one day I will probably bump someone else out there is perhaps using this 'KEY' (memory location?) and then my app will not work on their phone correctly.
My question is, how do I 'generate' this key so that there is no conflict of interest, or I use this PersistentStore wrong?
In the JDE if you highlight a string and a right-click, there is an option to convert it to a long. What most people do, is use a complete package more than name ID. Like: "com.foo.bar.mykey1."

Hello
will someone please solve my problem which is the key to registry or files will effect when we change the amount of disk space used to store in the offline files option when we go to control pane--> sync--> manageofflinefiles 8 victory while this option is not in the options of folders in Windows XPHello
Thanks for asking!
If I understand correctly, you want that registry key is responsible for the amount of storage on the disk space for offline files.
I suggest you to visit these links and check if it helps.
http://Windows.Microsoft.com/is-is/Windows7/manage-disk-space-for-offline-files (Applicable for Windows Xp)
http://support.Microsoft.com/kb/904676?WA=wsignin1.0
For the registry key, see this.
It describes the registry key that defines the value for an amount of
storage for use offline files:
HKLM\Software\Microsoft\Windows\CurrentVersion\NetCacheTo do: Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click on the number below to view the article in the Microsoft Knowledge Base:

By virtue of certificates of the Advanced tab "Safety devices" apparently already in mozilla... but not "responsible". In these safety devices is called «...» The private keys for PSM"that I have the OPTION 'Load', but I can't find any explanation as to what it is (I can guess, but since it is not"loaded"already, I don't think that it has nothing to do with"Private browsing").
What happens if I have to "load" all (there are others beneath "security devices, also * '), or that *"Security device"..? What function does?You need to do nothing. These are part of Firefox and are active.
- Built in Modules of roots - root certificates used for secure access.
- Security software - used by the Firefox password manager.
- NSS internal PKCS #11 - built-in library to manage cryptographic measures that are required for secure connections and encryption names and passwords.
