HT1343 Locking the keyboard using a combination of keys

There used to be a way to lock your keyboard from accidental activation using a combination of keys. Now, I cannot find the information on this. Does anyone remember the key combination to do this?

Hi Kwow Wei,
You can do this.But you need to explicitly pass the values to the RFC becuase in the form you are going to bind the fields to a Webservice model .
As I mentioned earlier it would be nice if you can post the scenario where you want to follow this kind of approch so that people can give their suggestion.
Thanks & Regards, Anilkumar

Is it possible to lock the keyboard of a client from a server using java

please explain wheterit is possible to lock the keyboard of a client from a server using java

You want to process code on one machine, and thereby lock the keyboard on another machine? No, that's not possible. It is extremely far from possible.
Of course, if the client is running software with security holes in it you might hack into it and crash the thing. This will lock up the keyboard pretty good. I hope that's not what you want ...
Or are you talking about a setup where you already have code running on the client, and some sort of communication between client and server? In that case what you need to know is whether it is possible to lock the keyboard at all. Once you have figured that out, it is trivial to add the communication code to have the server software tell the client software to lock the keyboard.
So what do you mean with "lock the keyboard"? It's pretty easy to remove/disable all keyboard related listeners in your own application. It's a lot harder (and AFAIK impossible with pure java) to disable alt-tabbing out of the application. And impossible, except from exploiting security holes, to lock the ctrl-alt-delete-combination on windows machine.

Is it possible to lock the keyboard please?

Hi
I've got a Pavilion dv6 notebook and would like to know if its possible to intentionally lock the keyboard. This is to prevent my 3 year old daughter from accidentally pressing the keys whilst she watches a DVD.
A speedy response would be appreciated as we're heading overseas tomorrow (Wed 9 Feb) and I'd like to know the answer before we fly.
thanks!

Not really.
Windows+L locks the laptop and requires a passsword. T
he problem is that the notebook can't be used while it is locked.
You woud be better off buying a travel DVD player if you want to avoid the risk of a three year old's curiousity.
Best regards,
erico

Auto locking the keyboard in curve 9300

Hello, i would like to know if there is a way, with the phone by itself or with any app, to auto lock the keyboard.
In any nokia phone (the old ones, not smartphones) you can set it to auto lock after X seconds you didnt use the phone. Thats what I need.
The thing is, i have the phone locked in my pocket. I recieve a call, I answer it, and when I finish, the phone stay unlocked. I forguet to lock it again, put in my pocket, and hell unleashes (phone calls, messages, and more without wanting).
So, I want my phone to lock itself after 15 sefonds in stand by. And to stay locked after i recieve a call.
Thanks in advance.

Hey Mr elancio,
The device does not have a setting
to lock the key board automatically; you can set a security password to
lock the device, but you will need to use a password to unlock each time:
Go to Options> Password> Change the Password field to Enabled.
Set the Lock after time and check off allow out going calls while locked
I hope this helps.

How to lock the keyboard - macbook

I know most people are trying to UNlock their keyboards....
My wife uses her macbook to show movies to my 3 and 4yr old while traveling. But the kids can't helpthemselves and after 5 minutes try and "type like mama". which inevitably stops the DVD causes another program to open or something. Anyone with kids knows this instant "mayhem and change" on the screen only encourages the behavior.
Good kids.. but who can resist playing with a Mac, regardless of how old they are
Is there a way to lock the keyboard to that only pressing a certain combo will enable it again? (and keep programs/DVD running)
Thanks
-mosermac2

There's not a function to turn off the keyboard however you can turn mouse keys on and most of the keyboard keys will be ignored.
The shortcut for this is pressing Option five times. Do it again to turn mouse keys off.
Also can be set in System Preferences > Universal Access > Mouse & Trackpad tab.

Is there a way to 'number lock', the keyboard

When entering numerical characters, if you use the spacebar, the keyboard reverts back to the letter character set. Is there a way to number lock the keyboard to stop this happening?
If not, it may be a consideration for a future update.

Can you lock the keyboard in position

Can you lock the keyboard

You can lock the screen, which would lock the keyboard/Screen. You can "Dock" the keyboard and "undock it". When the keyboard is up, hold your figer down on the bottom right (keyboard picture) and hit dock. To lock the screen double tap home, swipe right, on the far left big circle, tap it.

How do I 'lock the keyboard' to prevent any more keypresses being sent on X11/Linux/Gnome?

I am writing an anti-RSI/typing break programme for Ubuntu Linux in python. I would like to be able to "lock the keyboard" so that all keypresses are ignored until I "unlock" it. I want to be able to force the user to take a typing break.
I would like some programmatic way to "turn off" the keyboard (near instantaneously) until my programme releases it later (which could be 0.1 sec → 10 sec later). While I have "turned off the keyboard", no key presses should be sent to any
windows, window managers, etc. Preferably, the screen should still show the same content. The keyboard should be locked even if this programme is not at the forefont and does not have focus.
Some programmes are able to do this already (e.g. Work Rave)
How do I do this on Linux/X11? (Preferable in Python)

class KeyboardLocker:
def __init__(self, serio=0):
self._on = False
self.serio = serio
def on(self):
return self._on
def write_value(self,path, value):
with open(path, "a") as f:
f.write(value)
def toggle(self):
if self.on():
self.turn_off()
else:
self.turn_on()
def description(self):
path = '/sys/devices/platform/i8042/serio%d/description' % (self.serio,)
with open(path, "r") as f:
description = f.read()
return description
def turn_on(self):
try:
self.write_value('/sys/devices/platform/i8042/serio%d/bind_mode' % (self.serio,),
'auto')
except IOError, e:
self._on = False
raise
else:
self._on = True
return self.on()
def turn_off(self):
try:
self.write_value('/sys/devices/platform/i8042/serio%d/bind_mode' % (self.serio,),
'manual')
self.write_value('/sys/devices/platform/i8042/serio%d/drvctl' % (self.serio,),
'psmouse')
except IOError, e:
self._on = True
raise
else:
self._on = False
return self.on()
if __name__ == "__main__":
kl = KeyboardLocker(serio=0)
device = kl.description()
print "We got a lock on", device
proceed = raw_input("Do you want to proceed? (y/n)").lower().startswith("y")
import sys
if not proceed: sys.exit(1)
kl.turn_off()
import time
wait = 5
print "Sleeping few seconds...", wait
time.sleep(wait)
print "Voila!"
kl.turn_on()
raw_input("Does it work now?")
Tested on Linux Mint 12, X11, HP Laptop, Gnome. Not sure if any of that matters though :)
UPDATE Added an option to change the path, e.g. "serio0" or "serio1". And prints the description, for me serio0 gave me: i8042
KBD port, most likely if you have "KBD" in it, it's right, continue, otherwise I give you no guarantee :)

Locking the keyboard/screen during iPhoto slideshow?

I am a wedding photographer looking to step my game up to the next level. One of the ways I have decided that I want to do that is to set up a "same-day slideshow" at the reception. Essentually, this is a set of 20-30 images I captured during the day, that the guests will be able to view during the reception. I plan to tuck myself away while everyone is eating dinner [the only downtime for a wedding photographer] and quickly upload my images & place 20-30 of them into a slideshow in iPhoto. I then want to set my Macbook Pro up so that the guests can view the slideshow - my question is: is there any way to lock the keyboard/screen while the slideshow is playing so I can step away from my laptop and not worry about some smart-aleck trying to check his email? Thanks in advance!

You need an slideshow app that gives you more control over the Soundtrack.
Alternatives to iPhoto's slideshow include:
iMovie, on every Mac sold.
Others, in order of price: PhotoPresenter $29
PhotoToMovie $49.95
PulpMotion $129
FotoMagico $29 (Home version) ($149 Pro version, which includes PhotoPresenter)
Final Cut Express $199
It's difficult to compare these apps. They have differences in capability - some are driven off templates. some aren't. Some have a wider variety of transitions. Others will have excellent audio controls. It's worth checking them out to see what meets your needs. However, there is no doubt that Final Cut Express is the most capable app of them all. You get what you pay for.

Is it possible to lock the keyboard?

Hi,
I am using my MacBook Air for SKYPE calls and DVD's with my 20 month old and it all goes well until he decides to put his little fingers near the keyboard... I need to be able to lock it - a bit like on a telephone. Does anyone know if this is possible?
Thanks Felicity

Set a "hot corner" to invoke your screen-saver in screensaver preferences, and then set security preferences to require user password to wake from screen-saver.
Or try this......

How to lock the keyboard

Hello,
all i want is to lock all the keys of the keyboard except " arrow keys, esc key, and enter key" and aslo want to make sure that my JFrame should not be closed by "alt+f4".
Looking for Your replies
Thanks in advance
sandy

Try adding a KeyListener and listen for:
KeyEvent.VK_RIGHT
KeyEvent.VK_LEFT
KeyEvent.VK_UP
KeyEvent.VK_DOWN
KeyEvent.VK_ENTER
KeyEvent.VK_ESCAPE
and then use event.consume() on the rest. See the Swing tutorial on "How to Write a Key Listener"
http://java.sun.com/docs/books/tutorial/uiswing/events/keylistener.html

How can I block the keyboard using the glass pane ?

I have a problem with the GlassPaneDemo from the Java Tutorial in
the
uiswing/components/example-swing
folder.
When the glass pane is visible it blocks the mouse input but the
keyboard input doesn't. For example if the glass pane is visible and
you press the F10 key, the menu will be activated. So the keyboard is
not at all blocked.
Can this problem be fixed ? I mean, to really block the keyboard
when the glass pane is visible.
Here I wrote down the specification written in the
Java Documentation at the setGlassPane method from the
RootPaneContainer interface:
The glassPane is always the first child of the rootPane and the
rootPanes layout manager ensures that it's always as big as the
rootPane. By default it's transparent and not visible. It can be
used to temporarily grab all keyboard and mouse input by adding
listeners and the making it visible. by default it's not visible.
As it may be seen, one says that the keyboard input can be blocked.
HOW ?
In hope that I resolve the problem, I have made some changes such as,
adding a key listener to the glass pane add listening to the keyboard events,
but I failed to fix the problem.
Faithfully yours,
Sarmis

Here is an example that I think will work for you.
Note the consume() call on the event object. I think that is what you're after.
import java.awt.event.*;
import java.awt.*;
import java.io.*;
import javax.swing.*;
public class Comparer extends JFrame implements ActionListener
    private GlassComponent myGlassPane;
    private JTextField myField;
    public Comparer()
        getContentPane().setLayout(new FlowLayout());
        getContentPane().add(myField = new JTextField(20));
        setGlassPane(myGlassPane = new GlassComponent());
        JButton theButton = new JButton("Glass");
        theButton.addActionListener(this);
        getContentPane().add(theButton);
        pack();
    public void actionPerformed(ActionEvent anEvent)
        myGlassPane.setVisible(true);
    public static void main(String[] args)
        new Comparer().setVisible(true);
class GlassComponent extends JComponent implements AWTEventListener
    Window myParentWindow;
    public GlassComponent()
        super();
        this.setCursor( Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR) );
        setOpaque(false);
        addMouseListener( new MouseAdapter() {} );
    public void setVisible(boolean aVisibleBoolean)
        if(aVisibleBoolean)
            if(this.myParentWindow == null)
                this.myParentWindow = SwingUtilities.windowForComponent(this);
            Toolkit.getDefaultToolkit().addAWTEventListener(this, AWTEvent.KEY_EVENT_MASK);
        else
            Toolkit.getDefaultToolkit().removeAWTEventListener(this);
        super.setVisible(aVisibleBoolean);
    public void eventDispatched(AWTEvent anEvent)
        if(anEvent instanceof KeyEvent && anEvent.getSource() instanceof Component)
            if(SwingUtilities.windowForComponent( (Component)anEvent.getSource()) == this.myParentWindow )
                ((KeyEvent)anEvent).consume();
} HTH,

Locking the keyboard backlight setting

Hi All,
Just got a new t430s to replace a dell e6420.
I'm wondering if there is any way to force the machine to remember the keyboard backlight setting. It gets reset when the machine goes to sleep or the display turns off, very annoying!
I know I can press fn+space to get it back but it seems like it really should remember it or at lest be able to take a default setting, that's what my dell did.
I've poked around the bios settings and power options and can't find anything.
Thanks.
Solved!
Go to Solution.

None that I'm aware of. There are a couple of other threads on this topic in which people have expressed a need for this or similar feature, e.g. Possibility to activate keyboard backlight automatically
