Capturing Key press when the focus is not on VI. (event is not working).

I have a VI, and found similar in Forums. I need to catch key down event, when the focus is not on VI.
I attached the VI found in forum. Try to click on other window, for example on block diagram of VI, when VI is running and check if it works. The answer is no, it doesn't work. When you press any key, the led button must change it's state, but it does only when the focus is on VI's front panel. The question is how to control key press, when VI is minimized or inactive. Is it possible to catch key down or any similar event, when the focus is on any other application, not on VI?
Solved!

Have a look at the "Connectivity...input devices..." menu.
For an example, open the example finder and look for "basic input demo". It should give you some ideas. Good luck!

Hi Moe,
Sounds mostly likje a bad KB, do you have another to test with?
Or...
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts (Users & Groups in later OSX versions)>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

Hello, the 'Save As' dialog box used to allow the backspace button to go up one level in the directory when the focus is in the folder contents box but it does not work any more, please help.

Hello, the 'Save As' dialog box used to allow the backspace button to go up one level in the directory when the focus is in the folder contents box but it does not work any more, please help. BTW the same 'Save As' dialog in other applications still allow the backspace button to go up one level in the directory.

cor-el,
I kept forgetting and procrastinating about following your instructions, since I have internet access only for limited amounts of time and usually I am busy with important tasks when I am.
Out of the blue, the problem corrected itself (the Save As box started to open full screen, then shrunk down to a normal size and the edges can now be dragged to a custom size).
Even the copy and paste problem in the filenaming area seems to have been less troublesome lately even though there have been no updates to Firefox in a few weeks.
Even though I marked the solution as not helpful, the problem has in fact been resolved. I will save the solution instructions in case the issue returns.

How can we trape the Keys Pressed on the Keyboard and do action depending on the keys

I want to know how we can capture the keys pressed on the keyboard by the user and do necessary action depending on the key pressed by the user....
For example.... If user press Alt+q the form should go in the Enter Query Mode.
Can anyone tell me how i can do this in Form 6i....
Please Help me out from this problem...
Thanks in Advance

Can somebody point me to what I need to use to
intercept all the 'keys' for an application.
At the moment I have set Focus to parts of the
application when the Mouse is over it, and then get
the Keys with a KeyListener.
Is there a way to get the keys, as long as the Java
app is active.
- Its an image display program, and I want to use keys
for - next image , zooom etc etc.
If soemone could just point me to the right part of
the API to look in?java.awt.Toolkit.addAWTEventListener()
then use the mask defined in AWTEvent.KEY_EVENT_MASK to listen to all the events.

Catching Alt Key Press with the Key Down Filter Event

I am writing an application that requires specific key combinations using ctrl, shift, and alt in addition to a function key (F1, F2, F3, etc). The application works great except for when I try to catch an alt key press. The alt key press does not seem to fire an event eventhough it is an option in the PlatMods cluster as well as the VKey enum. When I press the alt key when my application is running the cursor changes to a normal mouse pointer from the usual finger pointer and prevents any other key presses from going through (in addition to not firing an event itself).
I have tried completely removing the run-time menu, which doesn't seem to help. I currently discard all keys after I handle them in my event structure.
I really hope that the only solution isn't using a Windows DLL. Any suggestions or ideas at all would be greatly appreciated.
Thanks,
Ames

Hi Ames
As Kileen has said Khalid has already given you a good solution to detect the ALT key.
I have another approach that might let you stick to your event-driven approach. I suggest that you have another loop in your app that polls the keyboard using the Input Device utility vi's. When this poll loop sees an ALT + KEY combo it raises a dynamic user event and will be processed in your event structure. This means you can keep your key down filter event to process the CTRL + KEY and SHIFT + KEY events.
Example attached in 7.1
cheers

How do I select the entire text when the focus is moved to one TextBox?

How do I select the entire text when the focus is moved to one TextBox?
There are three TextBoxes. I use <TextBox TabIndex="1"/> to set the order they are selected. When I enter one specific TextBox, I would like to have the entire text selected ... one key stroke removes all of the text in that TextBox.
bhs67

I do it the following way:
1. Override the OnStartup for the application. Use the following code: (VB.NET)
EventManager.RegisterClassHandler(GetType(TextBox), TextBox.GotFocusEvent, New RoutedEventHandler(AddressOf TextBox_GotFocus))
2. In the event handler use this code (again VB.NET)
Private Sub TextBox_GotFocus(ByVal sender As Object, ByVal e As RoutedEventArgs)
_theTextBox = CType(sender, TextBox)
If setFocusTimer IsNot Nothing Then
RemoveHandler setFocusTimer.Tick, AddressOf setFocusTimer_Tick
End If
setFocusTimer = New DispatcherTimer
setFocusTimer.Interval = TimeSpan.FromMilliseconds(10)
AddHandler setFocusTimer.Tick, AddressOf setFocusTimer_Tick
setFocusTimer.Start()
End Sub
Private Sub setFocusTimer_Tick(ByVal sender As Object, ByVal e As System.EventArgs)
setFocusTimer.Stop()
_theTextBox.SelectAll()
End Sub
What this does is register a handler for every textbox in your application. This will execute when the GotFocus event is raised and will allow you to do whatever (in this case select all) you want. A great way of handling things at the application
level.

Simultaneous key press on the keyboard GX600

hello guys,
i bought a MSI GX-600 thinking that it could accommodate my gaming needs however i found out that it cannot allow more than 2 simultaneous key presses on the keyboard. its supposed to be a gaming laptop right? i cannot play keyboard bashing games with this unless i use a gamepad or an external keyboard. have you experienced this on your laptop?
do you think an update of the bios will do the trick?
try this link to test if your keyboard can handle more than 2 keypress at the same time:
http://blog.nobien.net/2008/05/12/more-than-two-simultaneous-key-presses-and-keyboardeventkey_down-woes/
btw, i like this forum.

No, no, no, it won't, so please don't try it!
Also, if you read the comments in the link you posted, your answer is there:

The problem comes from the way in which the signal for the pressed keys moves from your keyboard to your computer. The signal is only 8-bit, and there are limits to how the signal can be changed to represent more than one key being pressed in combination.
Long story short, the guys who designed the origional keyboards made a descision to support all two key combinations, and then selected as many three key combinations as they could support with the hardware. This meant that some combinations had to be left out, and they had to make a descision about which ones were more important.
It just happens to be that they chose not to support three key combinations which involve the up arrow key. I do not think there is any solution to this problem…
If you're playing games, why not just remap the keys in the game's settings?

I recently just bought a iphone 4 im happy with the product and it didnt cost an arm and a leg but i was wondering when the iphone 4 will become obsolete as in not receaving updates anymore etc

Keep in mind that just because a device may not be upgradeable to the latest iOS release does not mean it cannot continue to work just fine on the last update it did get. There will be many devices that were incompatible with iOS 7 that will continuing to work just fine on iOS 6 for a long time yet. There are many people still using their iPad 1 despite the fact it stopped getting iOS updates after iOS 5.1.1.
One way to safeguard your apps against future incompatible versions is to keep a backup of all your apps in iTunes on your computer. That way, if an update to the app comes out that is not backwards compatible with your iOS, you still have a copy of the last version of the app that was compatible with your device and your iOS release.

"The 'charCode' property of a keyup event should not be used. The value is meaningless." Is this possibly caused by a virus?

I don't know what's wrong with my Mac Mozilla Firefox, version 3.6.8, but today, it started alerting me about an error message on the "Error Console". In every website I visit, it tells me: "The 'charCode' property of a keyup event should not be used. The value is meaningless." Is this possibly caused by a virus?
I saw a pop-up which did not allow me to click it when I scatter the windows on my Mac. I was using Private Browsing, with pop-ups disabled, but one pop-up managed to get passed my settings, and open in another window. It would not allow me to select it, so all I did was to close Firefox, and start a new session. So far, everything has been normal, I also deleted the cookies it installed.
But, I still keep seeing that "Error Console" notice under my "Tools" on the Menu Bar, and when I clicked on it, it listed errors (such as what I listed above).
Would someone explain this to me?
Thanks for your help!

The messages you see in the Error Console are mostly to assist the web site's author in resolving compatibility problems. Some of them can assist you in determining why a web site doesn't work as intended. The one you mentioned doesn't sound that suspicious, except that it occurs on many sites. Perhaps one of your add-ons is trying to monitor what you type?
To diagnose whether this is caused by an add-on or one of your settings, you could try the following:
First, make a backup of your computer for safekeeping. To back up Firefox, see [https://support.mozilla.com/en-US/kb/Backing+up+your+information Backing up your information].
Next, try starting Firefox in Firefox
[http://support.mozilla.com/kb/Safe+Mode Safe Mode]. Be careful not to "reset" anything permanently if you didn't back up.
Does that resolve the errors? If so, then an add-on usually is the culprit. If not, try creating a new (blank) profile: [http://support.mozilla.com/kb/Managing+profiles Managing profiles].
If the new profile works correctly, you can choose between further research on your old profile or moving key settings like bookmarks from your old profile to the new one. [https://support.mozilla.com/en-US/kb/Recovering+important+data+from+an+old+profile Recovering important data from an old profile].
Hope this helps.

How to listen for key press when air app does not have focus

Hi,
I am developing a application in air and part of the functionality I need is the ability for the app to listen for when a specific key is pressed, even when the air app does not have focus.
Is there support for this for windows or mac? If not, how might this be accomplished? ANE?

Ok Mr. Smartass...Ok
I'm building a browser that is always open, and when
a user presses Ctrl+F1 (notice, just those two keys,
I don't care what else they press...) the browser
will open up. That way, you don't have to wait for it
to load all the time.You have two ideas here. One is having a universal key map that always gets ctrl-f1 sent to your app. The other is a program that is constantly running so that you don't have to wait for it to open up. The former is not possible (and this is a good thing) As warneria and I have been saying, it is bad design for an app to try to force an OS to implement this kind of feature.
If you're not going to help please don't post at all;
it's a waste of time for both you, me, and anyone
else who may need help on the same subject. Why wouldBelieve it or not, I am helping you.

How to determine the exact key pressed when numlock disabled?

Hi there,
I am trying track the keyboardevent that triggered by pressing numpad keys as hotkey, but when the numlock is disabled, the same keycode, same keylocation was gotten as pressing in the standard keyboard. how can I determine if the numpad was pressed or the other control keys were pressed?
Thank you!

Capture key press events with ExtendScript?

Is it possible to do this? I can't find an example in the documentation or online anywhere. I'd really like to know when the user presses the arrow keys while viewing the slideshow in Bridge.
Thanks!

Thanks for the example Paul. I can see how to listen to key down events on Windows and Dialogs that I create. Do you know of way to listen for global (app-wide) key down events? These are not defined:
app.addEventListener('keydown',...)
app.document.addEventListener('keydown',...)
I'm trying to add to the slideshow mode by having a little palette dialog with the context information shown that I need. The default caption box doesn't have what our artists want. If the palette window is in focus, I get the keydown event, but if they're using the arrow keys to flip through the slideshow, I can't capture those.
Thanks for the help.

Sound on Key Press when Texting

I have the Sound on Key Press turned On (under Language & Keyboard > Multi Touch keyboard > Sound on Keypress) so when I type on the keyboard, I get the clicks.
I have noticed when I am sending a text message sometimes the clicks get softer in sound (less volume) then back to normal volume. I have turned the phone off/on at least twice and removed/reinstalled the battery and it still happens.
Any assistance would be apprecaited.

The sound for keyboard press is effected by the volume adjustment for notifications, if you adjust volume and turn volume down this will effect the volume for key press. Uncheck the option under Settings > Sounds> Phone Ringtone that says "Use incoming call volume for notificarion" this way the notification volume will not be affected if you adjust volume on device.

When the internet page comes up it says 404 not found, it wont find anything typed into the google

once you double click on the internet the first page that comes up with 404 not found. then when u click to enter what u r looking for in the google and press enter it will come up with the same response 404 not found.

A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.
