Disabling ALT+CTRL+Del keys

Hi Every body:
Can u please help me in disabling the end task for my swing application by disabling the ALT+CTRL+Del keys ..I'm not sure if that is possible in Java ...
Thanx in advance

Windows processes that key event before passing it to any programs including the JVM (which would pass other keys to your java program). I don't event think native programs can get these keystrokes unless they hook into the internals of Windows.
Short answer: No can do.

When I close firefox it doesn't really close it seems to be hidden. Then when I try to start it again I have to Alt, Ctrl, Del, go to process , turn it off then hit it to start again. I can not get it to open in the hidden process that it is in

Apparently when I close Firefox it doesn't really close. I get told when I try to open Firefox later "Firefox is still open, you must close Firefox, Then reopen it. Then I hit Alt, Ctrl & Del, go to process's then I have to close it then reopen it. It does not open until it is closed in process's.

The process can take a few seconds to close. Sometimes you need to use Task Manager.

How to disable system keys like alt+ctrl+delete...

Hi,
I was wondering if there is any way to disable system keys like alt+ctrl+delete and windows logo key etc... I would like it to get disabled when ever my java application is visible and I want it in pure java.
Thanks,

Thanks for all your replies but hey I've seensome
program ( downloaded from google ) do suchthing.
What they do is some kinda image thing appearsin
the
full screen mode and do all the tasks what I'veopt
for. So, I'm confused what is being done in
those
programs.
Even if it is doable (Ctrl, Alt Delete I don't
think
will be, Windows Key should be) It will not via
Java,
but JNI. So you would be better off hunting overthe
MSDN.137256 speaks the truth. Ctrl-Alt-Delete is a
HARDWARE interrupt caught by the OS. In modern
Windows it launches a widget that can be used to
shutdown, logoff or run task manager. I have many
doubts about what the OP is saying.

Bootcamp perfect - now need ctrl-alt-del key map

Hi Guys,
Installed bootcamp, XP SP2 on MBP works perfectly, joined local Windows domain - no worries - now on boot of course it wants the infamous cntl-alt-del key combo - I've tried just about everything but no luck.
In the end plugged in external PC usb keyboard, got in and turned off the requirement to enter ctrl-alt-del in windows as a work around.
Any ideas on how to map the MBP keyboard to work? Thanks all.

Ctrl Alt Del on Windows XP:
After installing,
1) go to Start>Run
2) Enter "remapkey" (witout quotes)
A nice GUI utility pops up to let you remap keys on your keyboard. You can use it to remap the delete key. I suggest using the Right Command key.
After saving, reboot and you'll be able to use Ctrl-Alt-(Right Command) to do a Ctrl-Alt-Delete and logon to Windows domains and other useful things.

The "alt, ctrl and shift" on the left side of my keyboard keys integrated notebook did not work. What should I do?

The "alt, ctrl and shift" on the left side of my keyboard keys integrated notebook did not work. What should I do?

Hi Luis Fernando Garcia,
Thanks for using Apple Support Communities. This article has troubleshooting for keys not working on your keyboard:
One or more keys on the keyboard do not respond
http://support.apple.com/kb/ts1381
Some keys don't work as expected
From the Apple menu, choose System Preferences.
From the View menu, choose Speech.
Click the Text to Speech tab.
If "Speak selected text when the key is pressed" is enabled, the key or key combination set to speak text cannot be used for other purposes or used to type text--click Set Key and change it to a less-commonly used key combination (try to use modifier keys such as Shift, Command, Option, and Control). Or, disable the "Speak selected text when the key is pressed" option.
Click the Universal Access pane in System Preferences, click the Keyboard tab.
Make sure that Slow Keys is turned off. With Slow Keys on, you need to press a key for a longer period of time for it to be recognized.
In the Universal Access pane, click the Mouse tab, and make sureMouse Keys is turned off. With Mouse Keys enabled, you cannot use the Numeric Keypad to enter numbers--instead the keypad moves the pointer (cursor). (There is an option to enable Mouse Keys with five presses of the Option key; you may want to turn that option off to avoid accidentally enabling it.) If Mouse Keys is enabled and you are using a keyboard with no numeric keypad or Num Lock function, seeUnable to type while Mouse Keys is enabled in Mac OS X.
If the function keys on the top row of the keyboard are not working as expected, see Mac OS X: How to change the behavior of function keys.
If the issue persists, use Keyboard Viewer to help isolate the issue:
Click the Language & Text pane (Mac OS X v10.6) or International pane (Mac OS X v10.5.8 or earlier) in System Preferences.
Click the Input Sources tab (or Input Menu tab in Mac OS X 10.5.8 or earlier).
Click the Keyboard & Character Viewer "On" checkbox to select it (click the Keyboard Viewer "On" checkbox in Mac OS X 10.5.8 or earlier).
From the Input (flag) menu, choose Show Keyboard Viewer.
If the keyboard is connected and detected by Mac OS X, the keys you type will highlight in the Keyboard Viewer window. Open TextEdit (or any text application), and try to type something using the keys that were previously not responding to see if they highlight in Keyboard Viewer.
Cheers,

ADF 10G : How to disable CTRL + Combination key ?

Dear all,
I developed ADF application using ADF 10.1.3 and have the requirement to prevent user from press the ctrl+ key ( like ctrl + p ) .
Firstly , I used JavaScript to disable this function and it worked on IE and Chrome but not on Firefox.
Actually, it work on firefox only the first time that user press ctrl key but when user press it again without reloading page , it is not worked.
This is JavaScript that I used
function disableCtrlKeyCombination(e)
            var isCtrl;
            if(window.event)
                //IE
                 if(window.event.ctrlKey)
                    isCtrl = true;
                 else
                    isCtrl = false;
            else{
                //firefox
                if(e.ctrlKey)
                     isCtrl = true;
                else
                     isCtrl = false;
            //if ctrl is pressed return false to disable
            if(isCtrl){
               alert('Key CTRL has been disabled.');
               return false;
            return true;
        }and I call this javaScript function with this code.
<af:document title="test" id="document1"
                    onkeydown="disableCtrlKeyCombination(event)"
                    onkeypress="disableCtrlKeyCombination(event)">So, I think there are other way that we can do with this problem or I have to modify coding to support this functionality on FireFox Browser.
Regards,
zenoni

Thank Frank and John,
I tried to follow the instruction that you give me but result still be the same.
I think the problem is not involve with javaScript because I can detect CTRL at the first time but the problem will occur in 2 cases.
1 . It will occurs when user press ctrl button for the second time after we close alert box .
2. when the page still shows alert message and user tried to press ctrl button ( ctrl+n and it worked)
So, I think Firefox have some background process that monitor user input or have some thing .

Xplorer X7-7700 Ctrl + FN , \ + Alt , Delete + Insert keys | SPLIT V2

Hi SVET,
I just purchased an MSI-1727 Barebone from a third party vendor (http://www.cyberpowerpc.com/system/Xplorer_X7_7700_Notebook/). I did some searching and found this post and another post for the A6000 about swapping the Ctrl + FN , \ + Alt , Delete + Insert keys (to look exactly how I typed it); and that is exactly what I was looking to do. Would it be possible if you could send me a bios that does this? I have read the posts about how to do it, and I would definitely be willing to make a donation.

Disable Alt+F4, Alt+Tab key press

Hi Guys, my WPF launched with maximized mode & i must restrict the users for the items:
'Alt + F4': Not to use 'Alt + F4' to close the application
'Alt + Tab': Not to switch to another application in the system, so i want to disable 'Alt + tab' key-press.
Note: I couldn't find any solution specifically for 'Alt + tab' key-press.
Thank you

Disabling ALT + F4 can be done by adding an event handler for the window's KeyDown event:
public Window1()
InitializeComponent();
this.KeyDown += Window1_KeyDown;
void Window1_KeyDown(object sender, KeyEventArgs e)
if (e.Key == Key.System && e.SystemKey == Key.F4)
e.Handled = true;
>>I couldn't find any solution specifically for 'Alt + tab' key-press.
The ALT + Tab keyboard stroke is handled at system level so you will need to hook into the Windows API to get access to the keyboard and intercept these calls somehow. Please refer to my example of how to use a low-level keyboard hook in WPF in the following
thread for more information:
https://social.msdn.microsoft.com/Forums/vstudio/en-US/cbb5d6ea-432d-42b5-a6e1-814cda9db030/registerhotkey-for-capslock-doesnt-work-in-laptops-keyboard?forum=wpf. There is probably no easy (or easier) way of doing this.
Here is an article that may also be helpful for you:

Alt-Ctrl-C not working, InDesign CS3, Windows

Hello,
We are currently running Adobe Design Premium CS3 and are having a hard time getting the keyboard shortcut Alt-Ctrl-C to work in InDesign.
I do have the ATI Catalyst control center application running at startup on my Windows Vista PC, however even though I have disabled hot-keys within this application Alt-Ctrl-C still fails in InDesign.
Just in case the ATI application was still intercepting the key press event I tried both changing the hotkey that ATI responds to and closing the application all together. Still InDesign refuses to accept Alt-Ctrl-C
Any ideas?

The solution is to STOP ATI Catalyst from starting up in the startup menu when booting XP.
I had the same problem and it was ATI Catalyst that was the offender. It has a built-in shortcut key of CTRL + ALT + C that is set to open the program and it overrides the one in InDesign.
People have tried to disable the shortcut keys in Catalyst, but in all honesty, you just do not need the thing open until you actually want to use it. It is sitting there are a memory hog.
I solved the problem by going into the Start Menu of XP and taking it right out of there so it doesn't start up at all. This then leaves ID free to use the shortcut of CTRL + ALT + C.
You can also go to the START button, then RUN, then type in MSCONFIG, and select the last tab on the right: Startup. Then disable the ATI Catalyst check box. Close out of everything and do a reboot of your system.
Hope this helps those with the problem.

Hotkeys Alt+Ctrl+F1 - Alt+Ctrl+F5 - which pre-install application intercepts them

I used to use keys combination from Alt+Ctrl+F1 to Alt+Ctrl+F5 as hotkeys for certain application. But in my new Lenovo ThinkPad w530 with Windows 7 x64 I can not do it, as it seems, that some pre-installed software has registered these combination for itself. When I press them, absolutely nothing happens, but if I try to assign these combinations in my app, i get the error message, that they are already registered for some other application.
I've checked twice all installed applications, starting from Window 7 itself. Seems, that none of them uses these keys.
Well, I've tried than to stop virtually any software, incuding resident utilities, but this hotkyes are still busy
Is there any ideas, which piece of software pre-installed by Lenovo might reserve these combination for itself?
Or is there any way to detect, which application intercepts handling this keys?
Thanks in advance!

So what? Whether nobody has the same issue with occupied hotkeys or has no time to answer?
I suppose, that the problem is somehow connected to the package Intel Management and Security Status, which is pre-installed by Lenovo. But i could not find any option to change these default hotkeys or disable them at all.

I inadvertently pressed CTRL+ another key (possibly V or B or N) and the text size of my bookmarked page was significantly reduced in size. I can't read it. How do I re-set the text size?

I mistakenly pressed CTRL + another key (possibly V or B or N or whatever), when I was reading my e-mail. The text size shrank to a size that is useless to me, but I cannot seem to get the text size re-set to normal. Indeed all of the formatting on the page has been reduced (symbols, instructions, frames etc). Existing Firefox and returning to the bookmarked page makes no difference. How do I re-set the system?

Hi,
Please try '''Ctrl''' + '''0''' (zero). Alternatively '''View''' ('''Alt''' + '''V''') > '''Zoom''' > '''Reset'''.

CS5.5: keyboard shortcuts: CTRL+ALT and problem with ALT+CTRL

The problem concerns the CS5.5 version of InDesign on Win7. Incorrect work-based keyboard shortcuts: CTRL+ALT+?? (system shortcuts and self defined, eg paragraph style). We have to remember to press the keys in order: CTRL+ALT+??. Ordering: ALT+CTRL+?? (vice versa to CTRL+ALT) will freeze the program on the selection on drop down menu (File, Edit etc.) and inability to perform any other function with the keyboard. This is a bug, or might be changed?
If we use shortcuts eg: SHIFT+CTRL+ALT+??, we must remember to first release the ALT key and then the rest. Otherwise, InDesign hang in drop down menu...

Welcome to the forum!
It sounds like you've inadvertently turned on the Sticky Keys accessibility feature. Since you didn't mention which operating system you're using, I can't tell you how to turn it off. Trying searching for Sticky Keys in Help in the Start button menu.
Hope this helps!

Combine ctrl+shift key (how)?

how to combine two keys at a time (like ctrl+alt) on button in action performed methode can any one make me understand by giving some small ex.

This thread shows how to assign Actions to KeyStrokes Ctrl+1 and Ctrl+2:
http://forum.java.sun.com/thread.jsp?forum=57&thread=193192
If you want to use Alt+Ctrl then use this line:
KeyStroke ks2 = KeyStroke.getKeyStroke(KeyEvent.VK_2, KeyEvent.CTRL_MASK + KeyEvent.ALT_MASK);
