Keyboard input for a nubie!!!!
Can anyone help me with writng a method that accepts all keyboard input and writes it to a file? I.e. whenever a key is pressed (only letters and numbers), it is accepted even if no programs are running and no text editor is being used.
This will help me great deal and I would be very appreciative for any help I might receive.
Thanking any response

Is this like making a key logger? It takes down all your input and saves it to a file? If it is I'm sure there are plenty of tutorials on how to make a key logger out there.
I guess you would have to look up buffered writer and rile writer methods, although I think they are just through a text editor or program.

Hi,
Is there some way I can assign keyboard input exclusively to plugin windows when they're in focus. Currently, when I type numbers or use the cursors, Logic is responding behind the plugin window and the plugins do not get the key press notifications. This means I can only use the mouse to enter input - that makes entering a License Key VERY DIFFICULT if it includes numbers!
Thanks in advance for your help,
AlexJust to clarify... I'm talking about my laptop keyboard, not a musical keyboard.
I'm kind of bummed that nobody has replied yet... can I be the only person who is having this problem?!?
I've tried this with native plugins too and get the same problem. The Logic Express 8 manual states that you can alter the value in a plugin by clicking on the numeric display and typing in on the keyboard. I tried that but when I try to type, the numbers activate their associated 'screensets'. I've even unmapped the number keys from the screensets and am able to use the numbers now, but there are other keys that do undesirable things in Logic that I don't want to have to 'unmap'. Also, I want to be able to use the cursor keys 'up' 'down' etc to choose options in plugins - but they change channels etc in Logic instead of being picked up in the plugin.
I can't be the only person with this problem can I? Please if you're reading this can you give it a try and post back here describing your experiences.
THANKS!

Hi, I have an issue with my first LabView program can anyone help me please?
The function of my program is to manualy or automaticaly save the data obtained with the multimeter
My program worked fine until I wanted to add a file creation function each time the program runs, but the program creates a file every 5 seconds, I have tried using a loop and case but I cant make it work, it still creates a file every 5 seconds.
Any tips?
Aditionaly I have tried to program a keyboard input for the buttons in the vi using a few examples I found around the forum but my program just lags and I cant even start measuring.
I atach my vi for inspection , thanks in advance

maybe.vi 32 KBIt probably shouldn't damage anythin constantly updating the loop, although it does introduce overhead and is generally not tidy, to avoid the constant updating I would recommend looking into shift-registers or feedback nodes. On that note, I'll leave you with this snippet, I'm sure you can see how it might apply.
[Side-note; In case you don't know how to use a snippet, download and save the image, then drag the file from your explorer into a block diagram.]

Safari 7.1 blocks all keyboard input in Flash app
Safari 7.1 on OSX 10.9.5 blocks any and all keyboard input for FlashPlayer applications!! Everything worked fine until the upgrade to Safari 7.1 and OSX 10.9.5. Tried FlashPlayer 14 and the latest 15 -- still no keyboard input, not even in debug mode (I'm a developer of enterprise apps for browsers).
The same app still works just fine in Firefox and Google Chrome! Is this just a mishap on Apple's side? Or just another hit to kill off the most productive computer language I've ever used (and I used Apple's own Objective-C as well)??
Come on Apple! I love you guys and use your products a lot, but is this really necessary for the most powerful and valuable company in the world -- to hurt a language with such tricks that doesn't do you any harm at all?? This makes you look more like the "PC guy" from your own former commercials (instead of the lovable "Mac guy") ...From the menu bar, select
▹ System Preferences… ▹ Flash Player ▹ Advanced
and click Delete All. Close the preference pane.
From the Safari menu bar, select
Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. Test. -
Keyboard input not working at boot
Hello --
I don't get keyboard input for ~30 seconds at boot, and I'm not sure why. I'm using a hand-rolled kernel with no initrd, though when I use the stock Arch kernel with initrd it does the same thing. According to my kernel logs, the keyboard is recognized before the root filesystem is mounted (and it appears to be PS2, not USB), and from reading the rc scripts, little or nothing happens after the ttys are started.
udev starts before the root fs is mounted, and when root is fscked at boot, I don't encounter this problem. Therefore I think udev is at fault. Via I can't find any information on telling udev to deal with the keyboard earlier.
Any ideas on how to fix this? Other than putting "sleep 30" in my rc scripts, that is.Sorry, I wasn't being very clear.
I'm using a laptop, and lsusb doesn't report anything except the buses themselves. Therefore I concluded that my keyboard is not a USB keyboard, as I mentioned above.
This is booting to a tty console, not to X, so it can't be a KDE issue. And I have full control of my keyboard with GRUB; it's just the kernel that hesitates to acknowledge its existence. -
I am a new programmer trying to create a simple keyboard input for a Jframe, if that is possible. Here is a simple jframe creation:
public static void main(String[] args) {
JFrame frame = new JFrame("Keyboard input");
frame.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
// make window visible
frame.pack();
frame.setVisible(true);
If I wanted to make a class that would put a ball in the frame and have the ball move up, down, left, or right according to which arrow keys were pressed and held- how would I do that?
Thanks for your help,

In that link are all three of my classes (UserInterface.java, CalcEngine.java, and Calculator.java)
I'm trying to do keyboard input for the numbers, the decimal, all the operations and enter. But the way I have it set up, I can't get any of the methods in the CalcEngine.java to run once a button is pressed. It's hard for me the explain, but if you compile it and try looking at the code, you'll understand what I mean.

OSX/SL 10.6.8 all window apps lose keyboard input; mouse and cmd-N work for spaces
Input suddenly stops going to all applications, from MacBook Pro and wireless keyboards, and from "Show Keyboard viewer" (OSX 10.6.8 'Snow Leopard', MacBook Pro). Though the OSX Keyboard Viewer shows the keys onscreen as they are pressed on the MacBook and wireless keyboards. 'Spaces' responds to cmd-N commands, but no input is possible to any running or newly-started 3rd party or Apple-provided application. Killing off applications one by one doesn't recover keyboard input ability; a complete reboot appears necessary to restore the ability to key input into applications. This happens repeatedly, yet never registers as an OS/X 'crash' because 'Force Quit'ting applications and restarting is still possible using only the magic mouse or trackpad. No data whether only logging out and back in would correct the apparent input-focus disconnect of all applications with the window manager. There may be some way to restart the window manager by using the mouse to open up new apps and/or cut and paste characters ( including a carriage return ) or cut and paste entire saved typed commands into a terminal window.
Do a backup, using either Time Machine or a cloning program, to ensure files/data can be recovered. Two backups are better than one.
Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.
Isolating an issue by using another user account
If the problem is still there, try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don't do them all at once.

I have a VI that, when started, starts another vi that runs in a
different part of the screen. I want the user to be able to use the
keyboard and the original VI be the one that receives the keyboard input
(key navigation, etc.). How do I get the focus back on the original VI
without "clicking" on it with the mouse?
-StephenTry using Property Node under Application Control. Set the class to VI.
Set FP.IsFrontmost to true. Wire the name of the original vi to the Open VI
Reference function and then wire the output vi reference to the property
node. This should return keyboard control to the original vi. If you want
a specific control within the vi to have focus initially, right click on the
control and create a property node. Select KeyFocus for the property,
select Change All To Write, and wire true to the property.

I downloaded CS1 for my Comp. Sci class in order to use Keyboard input in my Java coding. However, I don't know where to put the downloaded .jar file. Could somebody please help me? This is where I downloaded it from: http://duke.csc.villanova.edu/jss1/bookResources/keyboard.jsp
ThanksHi Max
It's not your fault but I am appalled that Java teachers are still using bodges like the Keyboard class, when the standard Scanner class has been available for over 12 months.
So here's what I suggest:
1) Try putting the jar file into /Library/Java/Extensions
2) Tell your tutor to get his notes up to date and use the Scanner class instead of Keyboard

How can i enable both paired bluetooth and ios keyboard input at the same time?
This is needed for the app im working on. Need some user input via keypad as well as scanner input via a paired bluetooth scanner.You probably should not be using a keyboard bluetooth profile for a scanner, I am not a developer for apple so do not know the location for you to find out the correct profile you should be using for an input device that is not a keyboard. Sorry,
I am sure if you navigate the apple developer site you will probaly finmd what you're looking for.

I have a new mac book pro (sept 2014) and am suddenly stuck on the log-in screen. Keyboard input is not working to enter my password. Seems to be a log in issue as keyboard works for forced troubleshooting. (And b/c when I first noticed the problem, I was able to enter my log in password but then everything sort of froze. Now, no ability to enter the password.) Already tried a basic restart and a cmmnd/ cntrl/ pwr troubleshoot to no effect.

How to have same keyboards input source in Mac and Windows???
I use Canadian French-CSA on my Mac keyboards input source. Using Windows 7, I can't find the good setting for my keyboards to be the same when I it keys.
I run Windows over Parallels Desktop
Can anybody help?
Thank youCan I use an AirPort Extreme Base Station "n"
Yes.
and if so, will my MacBook work with this at maximum download / upload speed (i.e. equivalent to the cable)
The speed of your internal network generally is much much faster than the speed of your internet connection. Unless he has an internet connection faster than approx 6Mbps then even dropping down to the old 802.11b Airport would not seen any decrease in speed of downloads etc...
and will my brother's PC's also be able to connect?
If his PC is 802.11b/g-compliant, it shouldn't have any problems connecting to the AirPort base station.
Or is there another Airport base station?
The other AirPorts would work, but the AirPort Express & older 802.11g AirPort Extreme base stations have a max. range of 150 feet.
OR-- should I head down to "Generic Computer Store" and just by a wireless router (WiFi)(think that's what they call them) and connect this to his cable modem? IF SO WILL THAT WORK FOR MY MAC?
That is always an option as well, especially since he will be the primary user throughout the year. I'd suggest going with a brand name, like Belkin, D-Link, or Linksys for the wireless router choice. -
Firefox and Thunderbird are suddenly not accepting keyboard input
Keyboard shortcuts still work just input in any kind of input field fails so I can still use ctrl+C / CTRL+V to somewhat use firefox and Thunderbird But all input fields are completely unresponsive to keyboard input
The problem suddenly arose while I was browsing.
I have the same issue on all program's based on the Gecko engine and I confirmed them so far in Firefox, waterfox, instantbird, thunderbird and fossamail. However chromium / windows / basically everythign n
To fix it I tried the following:
Restarting firefox
Restarting firefox in savemode
Rebooting
Changing the keyboard layout in windows
Using a different keyboard
Again rebooting
Pressing F7 to check for caret mode which was disabled
pressing winkey + F9 (Whatever that does)
I am running windows 8.1(x64)Solved, Changing the keyboard layout again and rebooting fixed it. I tried using the on screen keyboard which worked so I changed the keyboard layout again and rebooted and now it works just fine. I still wonder what caused a Gecko wide issue like this?

Default Keyboard input change in using roaming Profile on different Win 7
We found a strange problem on default Keyboard setting.
We are using roaming profiles for all users.
One of our users is using two Windows 7. One Windows 7 is VDI for working out of office and another Win 7 is her local PC.
She is only using Two keyboard input: Chinese Traditional English and Chinese Traditional Pinyin.
Whenever she had used the Windows 7 VDI, when she comes back to office and use her local PC, the default Keyboard input will automatically change to Chinese Traditional Pinyin.
The user said she had not changed any default keyboard input in the VDI of local PC.
Is there anything we can do for this issue?
