Purge Preferences and P_PRESERVE_CASE to true

Hello,
Environment:
- Application Express 3.2
- Oracle Database 10g Express Edition
In my login process (wwv_flow_custom_auth_std.login) on page 101 I use the parameter P_PRESERVE_CASE => TRUE because I use also P_UNAME => lower(:P101_USERNAME). I want to keep the username in lower case.
I noticed that preferences that appear in “Administration > Manage Services > Manage Preferences > Preferences by User” report can not be purged.
In the screen “Administration > Manage Services > Manage Preferences > Purge Preferences” when a username (that is in lower case) is selected, the report that should display the preferences (automatically created by Apex) of that user displays nothing and the Purge User Preferences button does nothing.
Is there a bug somewhere? Does someone could help me to purge users’ preferences in case username is kept in lower case?
I know that I could use APEX_UTIL.REMOVE_PREFERENCE but I would like to avoid using this procedure manually for each preference to purge.
Sorry for my bad English, it is not my native language.

Sebastien,
This is a bug. Thanks for pointing it out. I don't have a workaround for you, unfortunately.

I would like to completely purge Yahoo's search engine from my macbook pro lion and all of my browsers (I've been through each of the preferences and the settings tab and it still pops up)

Yahoo is still popping up as my primary search engine even after going through preferences and setting each for google. Now I'm really not likeing Yahoo who seems to be more like a spammy virus than an option. This happened after I got my Apple computer back from repair and now I am stuck with it-when you right click you can see it as the main option for searches which tells me it's somewhere deep. This only makes me dislike Yahoo even more. Thank you for the help.

Storing an array of checkbox booleans into preferences and retrieving them

Just wondering how to go about storing an array of JCheckBoxes into a preference and retrieving it. There's 32 checkboxes so if they select, say, 6 of these randomly it should store it in a preference file and retrieve it when the application is loaded so that the same 6 checkboxes remain selected. I'm currently getting a stack overflow error, though.
import java.util.prefs.*;
public class Prefs {
     Preferences p;
     GUI g = new GUI();
     public Prefs() {
          p = Preferences.userNodeForPackage(getClass());
          g = new GUI();
     public void storePrefs() {
          for (int i = 0; i < g.symptoms.length; i++) {
               p.putBoolean("symptoms", g.symptoms.isSelected());
     public void retrievePrefs() {
          for (int t = 0; t < g.symptoms.length; t++) {
               p.getBoolean("symptoms", g.symptoms[t].isSelected());
symptoms is the array of checkboxes in the GUI class. Not sure where I am going wrong here. I can do it with strings from textfields etc but this is proving to be an annoyance. :(
Thanks in advance

Actually, I have a better example, see below
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
import java.util.prefs.*;
public class PreferencesTest {
    private Preferences prefs;
    public static final String PREF_OPTION = "SELECTED_MENU_ITEM";
    public void createGui() {
        prefs = Preferences.userNodeForPackage(this.getClass());
        JMenuItem exitAndCloseMenuItem = new JMenuItem("Exit");
        exitAndCloseMenuItem.addActionListener(new ActionListener(){
            public void actionPerformed(ActionEvent e) {
                System.exit(0);
        JMenu fileMenu = new JMenu("File");
        fileMenu.add(exitAndCloseMenuItem);
        JCheckBoxMenuItem[] preferenceItems = {
            new JCheckBoxMenuItem("pref 1"),
            new JCheckBoxMenuItem("pref 2"),
            new JCheckBoxMenuItem("pref 3"),
            new JCheckBoxMenuItem("pref 4")};
        int selectedMenuItem = prefs.getInt(PREF_OPTION, 0);
        preferenceItems[selectedMenuItem].setSelected(true);
        ButtonGroup preferencesGroup = new ButtonGroup();
        JMenu preferenceMenu = new JMenu("Preferences");
        for(int i = 0;i<preferenceItems.length;i++){
            preferenceItems.setActionCommand(Integer.toString(i));
preferenceItems[i].addActionListener(new menuItemActionListener());
preferencesGroup.add(preferenceItems[i]);
preferenceMenu.add(preferenceItems[i]);

f.setJMenuBar(menuBar);
f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
f.pack();
f.setLocationRelativeTo(null);
f.setVisible(true);
public static void main(String[] args){
new PreferencesTest().createGui();
class menuItemActionListener implements ActionListener{
public void actionPerformed(ActionEvent e) {
JCheckBoxMenuItem jcbm = (JCheckBoxMenuItem)e.getSource();

Force Quit resets preferences and presets in InDesign 5.5

I just installed InDesign 5.5 awhile back and got all my printer presets and general preferences set up. I began to notice when I "force quit" the program they all disappear (or return to the default) and it is a hassle to reset everything especially all the printer presets. I've stopped quiting the program through "force quit", but still on a occassion when the program freezes then I occassionally have to "force quit". I didn't have this problem with the previous verson of InDesign. What can I do to keep my preferences and printer presets from resetting after a "force quit"

If you can't find another solution you could try the applescript below. I use it to roll out user settings in the studio, but it is also useful for very quickly replacing corrupt prefs files. It will overwrite whatever is there.
# Indesign CS5.5 preferences
set sourcePrefsFolder to POSIX file "/Volumes/Server/Folder/Folder/Etc" -- change this to your source folder
set destPrefsFolder to (path to preferences folder from user domain as text) & "Adobe InDesign:"
set checkDestPrefsFolder to existsItem(destPrefsFolder)
-- checks the existence of the preference folder – this will not be there if InDesign has never been started
-- if it's not there it creates one
if checkDestPrefsFolder is equal to false then -- i.e. the User's InDesign prefs folder is not present
    tell application "Finder"
        make new folder at (path to preferences folder from user domain as text) with properties {name:"Adobe InDesign"}
        duplicate sourcePrefsFolder to destPrefsFolder with replacing
    end tell
else
    tell application "Finder"
        duplicate sourcePrefsFolder to destPrefsFolder with replacing
    end tell
end if
-- handler to check for existence of an item
on existsItem(itemToTest)
    try
        itemToTest as alias
        set myBoolean to true
    on error
        set myBoolean to false
    end try
    return myBoolean
end existsItem

How can I move my preferences and extensions to a new computer? Have I done it successfully?

My old computer crashed. I've set up the new computer. I copied all the profile files/folders to the profile on the new computer in both the local and roaming folders.
Does this copy over my preferences and extensions? The help pages say they don't tell how to copy those since they can be the cause of problems. However, they weren't problems. So I want them copied. The extensions folder on the old computer was empty (I don't recall if It'd had any installed or just bookmarked some.) I remember making some specific preferences changes in that "advanced" file (that worked fine afterward.)
So with what I did, did I successfully copy everything over? If not - where are the extensions and preferences so that I can copy them over?
Bonus big question - is there a way to merge my old browsing history with the history on the new computer that I used for 10 days? Right now I set those 10 days as a separate profile, so I can save and go check it if I really need to.
Thanks!

Take the good profile and copy it to the new computer. Also copy all
of your add-ons. On the new computer, start Firefox. Once it is running,
shut it down. Then transfer the information from the old profile to the new.
Thess add-ons can save all add-ons into a single folder for transfer.
These add-ons can be a great help by backing up and restoring Firefox
'''[https://addons.mozilla.org/en-US/firefox/addon/febe/ FEBE (Firefox Environment Backup Extension)]''' {web link}
FEBE allows you to quickly and easily backup your
Firefox extensions, history, passwords, and more.
In fact, it goes beyond just backing up -- It will actually rebuild
your saved files individually into installable .xpi files.
It will also make backup of files that you choose.

"Itunes cannot read the contents of ipod. Go to the summary tab in Ipod preferences and click Restore to restore this ipod to factory settings." What is this?

I have been getting this error message since about the end of June when I updated to the latest version of iTunes. It's pretty annoying. Let me lay out how this has been happening for the past month, the best I can. I have a 32GB 4th gen iPod Touch
I load content up to my iPod. Music, Apps, Videos, pictures, etc.
My iPod works well for a little while, days sometimes a week is the longest I went without seeing this message.
I connect iPod back to my laptop through the standard pack in Apple USB connector.
I get the "Itunes cannot read the contents of ipod. Go to the summary tab in Ipod preferences and click Restore to restore this ipod to factory settings." message. When I go to the preferences tab, I click restore and iTunes gets stuck trying to restore my iPod. Then I have to uplug my iPod. And Shutdown/Restart my PC reconnect my iPod, and go through the restore process again.
I have been doing this for as I said, a month. It's getting pretty grueling to keep havomh putting cotent on my iPod after these restores.
I've tried everything.
I've stopped autosync, it still happens.
I tried to reinstall iTunes(be it I didn't full uninstall before trying to install again and got the option to fix corrupted files and such
I've deleted all old back up, and it still happens
Today is the fist time I'm fully uninstalling iTunes, and then reinstalling to see if this works.
But do you guys have any otehr solutions for this? As I said, this didn't start happening until I installed the lastest version of iTunes 10.6.3

- Have you tried another cable?
- Another USB port?
- When you have the problem, connect it to another computer to help determine if you have an iPod or computer problem.
- Try just restoring the iPod to factory settings/new iPod. Do not restore from backup. If you still have the problem with this and all computer that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

I have a PowerBook G4 with a non-functioning monitor. It used to work with an external monitor, but I reinstalled the OS, which cleared the display preferences and now when I restart it won't detect the external monitor. How do I fix?

I have a PowerBook G4 with a non-functioning monitor. It used to work with an external monitor, but I reinstalled the OS, which cleared the display preferences and now when I restart it won't detect the external monitor. This means I can't use the computer anymore. How do I fix? I tried using the Command+F2 keyboard shortcut, but it doesnt' work. It's possible that since I reinstalled the OS, it still needs to be set up, so there's only a welcome screen (but since I can't see it I'm not sure).

There is no limit to the number of times you can re-install Office on the same computer.

I cannot enter the key code for updating to QuickTime Pro 7 as there is no Icon in Preferences and no Registration option in menu?

I have followed the clear instructions to enter the purchased key code for QuickTime Pro 7. There are two options offered:-
1. Go into Preferences and select the QuickTime Player icon and enter the code that way.
2. Open QuickTime Player and open up ‘registration’ and enter the key code.
For whatever reason I have neither option available to me although QuickTime player is on my system and I use it regularly. It is version 10 build (118). I have run software updates and there is no upgrade available. I have downloaded the latest version and tried to load it but this fails because the system finds a version already available. I have attempted to uninstall but whilst it moves it from the Application folder, it remains on the Mac as it is part of the system files. So I cannot use the Pro version. The iMac is a 27” Intel about a year old and has all the software updates available to me installed.
Any offers for suggestions or past experiences that can help me overcome this conundrum?

Both answers were spot on. I made the mistake yesterday of downloading the version for Leopard in my haste. I also thought the issue was related to having to uninstall the current version X.
So the moral of the episode is check the version you have and make certain you download the correct version for your system. All works now.
Thanks chaps!

What really cheeses me off here is that Apple isn't allowing users enough customization. With each update of iTunes (and the OS and iOS) we're forced to give up something that worked well for the way we want to use the app and make do with fewer (and lamer) options. If Apple keeps this up, they're going to start losing customers fast. I mean if this isn't fixed soon, I'm pretty sure I'm going to give up on iTunes, and then I'll probably go ahead and get a Galaxy when I need to replace my iPhone.
What I don't understand about how they won't let users delete the list of available podcasts now is why? How is this making it a better program? I can understand that not all users are capable enough to right-click on a feed and select "Show all available episodes", so I can see why they want the complete list to be the default (and, surprise, it already was). But to not give users the option to delete that list? It's inconsiderate because it makes navigating feeds with a large back catalogue really frustrating. I'm flabbergasted that no one at Apple considered all the podcast feeds that keep hundreds of episodes available when they removed this feature. It smacks of rank incompetence.
What improvement were they trying to make here anyway? There was nothing wrong to my mind about how podcasts were managed in previous versions. Whatever improvement they were trying to make here, they should have realized that many users would at least want the option to keep things the way they were.
And reverting to a previous version is no solution. I can't sync my iPhone with the new iOS without this update, and (while I do have some issues--specifically how you can't play podcasts in the Music app anymore) I do like the new iOS.

You're saying that when you click on the iCloud preference pane button it sends you to the defunct MMe
rather than giving you this?
Is your profile up to date, i.e. are your running 10.7.5? Make sure you click on the iCloud button and not the MMe button.

With 10.2 I can only use system speaker output for audio, NOT my RME FF400 I used previously. The FF400 works fine with other apps. How can I set this device in FCP 10.2? (it is set in both system preferences and midi)

With 10.2 I can only use a system (e.g. speaker) output for audio, NOT my RME FF400 I used without any problems previously. The FF400 works fine with other apps (some like TwistedWave) setup in the program, and others (like Spotify) using system preferences & audio midi setup. How can I set the FF400 to be the sound output device in FCP 10.2? N.B. The FF400 is set as sound output device in both system preferences and audio midi setup.

From the fcp.co forum. See if this does anything for you.

I have the solution! Well it at least worked for me. This is the response I got from Apple, Can you please try the following steps towards fixing your audio issue, and report back with your results?
1. Open the application Audio Midi Setup (located in Applications : Utilities)
2. Select the Output Tab for the current output device
3. Select the Configure Speakers option
4. Select the Multichannel tab
5. Change the setting to Stereo Now mine was set to stereo but the left channel wasn't showing left. re-clicking on stereo reloaded the settings and after clicking apply it worked.

How can I stop iMovie from making thumbnails of clips from past projects when opening the program to digitize new clips for new project. i have looked in the preferences and couldn't figure out what to disable.

How can I stop iMovie from making thumbnails of clips from past projects when first opening the program to digitize new clips for a new project. It takes forever for it and is very annoying. I have looked in the preferences and couldn't figure out what would disable this problem.

You do not need to move your cursor much when pressing the mouse button to cause the tab to tear-off/tear-away into a new tab. No "sensitivity" setting that I am aware of. The tab in the new window can be dragged back to the original window.

Moved my library to an external hard drive. Now I get this message when trying to import video: Cannot start ingest because there is no storage location set. Please set one under Storage in Preferences and try again.

I recently moved my iMovie Library and all of its contents to an external hard drive. I then erased the library and all of its contents from my iMac HD and created a new library. Now when I try to import video from my DV camera I get this message: Cannot start ingest because there is no storage location set. Please set one under Storage in Preferences and try again. There is no way to set a storage location in Preferences. I have chosen an Event in the middle drop down box. But it still will not import. Any help will be greatly appreciated.

My iTunes library is set up the way I said in the top post and works totally fine.
Yes, and that is the default structure to which I was referring. iTunes will organize it that way automatically unless people do start changing settings (in which case they should know what they are doing and how iTunes works with library files and media structure.)
Both ways work, the advantages of mine would be that should iTunes try looking fo a library, it will always be in the default location.
It makes people think they have to change media location in preferences. They do not unless they want to relocate media only and leave other things on their internal drive (in which case there is no point in copying library files to the external, and you certainly wouldn't want to then delete them from your internal).
Downside is that then should someone move their iTunes library to anther computer they need to remember to get those library files on the external hard drive.
Just copy the whole iTunes folder and it will get the library files to the other drive in one step, along with all the other files.
Your post has good stuff but it makes a move appear intimidating and look like people have to do a lot of organizing to move the collection. It also throws in extra steps (namely altering preference settings) that could cause confusion or even make a mess of things. If people leave iTunes to default preference settings (which most people do) the move summarizes into a short line: Copy a folder and hold an extra button the next time you start iTunes.
Note that the instructions in the link I provided earlier do also include many steps, but those are to ensure that everybody does have it all organized correctly before simply copying the iTunes folder. In the end it is just a simple action.
