Keyboard input - single char
All I want is a single character of keyboard input. Is there a better (simpler) way to do this?
byte[] bInput;
String cResult;
bInput = new byte[1];
bInput[0] = 0;
System.out.print("\nStart FirewallChat in [C]lient or [S]erver mode? ");
try
{ System.in.read(bInput);
} catch (IOException e)
{ System.out.println("System.in.read(byte[] b) threw IOException. An I/O error occurred - maybe the input stream has been closed? Exception follows : " + e);
System.out.println(Character.toLowerCase((char)new Byte(bInput[0]).intValue()));
char c = (char)System.in.read();

Parsing single chars to a vector.
I'm reading from a file, using BufferedReader. Readig a line at a time. Currently i have a StringTokenizer which breaks up the line using whitespace. How can I break up the "input" line by single chars, and how do I get the delim to work using the StringTokenizer, so that I can use other char instdead of using whitespace- or set up mutliple delims.
Is there a way I could add the single chars to a vector as an indvidual element to the vector so that I can bump off the elements that I do not have a use for?In order to use the " character, you need to use the escape character \" So, your statement would look like
st = new StringTokenizer(yourString,"\"<");The second char in that is a <, but the parser on the site sometimes converts it to the html code as & lt; Just use whatever chars you need in the second parameter

PPC apps (on intel): slow startup, no keyboard input, Excel-Office crashes
Hello,
It seems, that all apps that are using rosetta don't work properly.
- The startup time is extremely long, some minutes, spinning wheel is visible
- input via keyboard isn't possible
- Office v. X (Word, Excel, PowerPoint) apps are crashing at startup
A test with the Calculator.app switched to open with rosetta showed also this symptoms (no keyboard input possible)
Curiously all this happens *only with my account*. So first I thought it is a problem of the preferences or fonts. But deletion or substitution from backup does not succeed. Also I did the tip sudo "update_prebinding -root / -force" but it didn't help.
I mad up a fresh account and compared all the files in the ~user/Library path, if there is a file missing in the brocken account. But didn't found some.
Is there anywhere a file outside the ~user/library path, which has user dependend informations (for rosetta)?
Many thanks in advance for any idea
GeorgeYeah, I've got it!
In /Library/Caches I found the following files and trashed them. Now all PowerPC application incl. Office v. X are working again. Huh!
(My User ID is 504)
com.apple.ImageCaptureExtension2.ICADeviceDatabase.504

I didn't look for the single fault in any of this files, but maybe someone has an idea, which file is related to rosetta and likes to post it.
Best regards and thanks to everybody who thoughts about a solution for my problem

Validating keyboard input data
I am new to java and have a question regarding validating input.
I did check the FAQ for "Validating keyboard input data" but found no help.
I have to check that the keyboard input is only one of the following char a c,C,d,D
Ihave tried different conditional loops and statements but cannot get it right.
Could someone point me in the right direction.
I am using the latest java.
Thanxwell i think i am close but i can't figure out why i have an endless loop or how to fix it
System.out.print("Please enter the Costumer Type C or R: ");
String cosTypeTemp = scan.nextLine();
cosType = cosTypeTemp.charAt(0);
while (cosType != 'c' || cosType != 'C' || cosType != 'd' || cosType != 'D');
do
costumerType = 'N';
System.out.print("Wrong input please enter the Costumer Type c or r: ");
cosTypeTemp = scan.nextLine();
cosType = cosTypeTemp.charAt(0);
while (cosType != 'c' || cosType != 'C' || cosType != 'd' || cosType != 'D');
costumerType = cosType;
System.out.print("Please enter the Number of basic service connections: ");
System.out.print("Please enter the Costumer Type C or R: ");
String cosTypeTemp = scan.nextLine();
cosType = cosTypeTemp.charAt(0);
while (cosType != 'c' || cosType != 'C' || cosType != 'd' || cosType != 'D');
do
costumerType = 'N';

costumerType = cosType;
System.out.print("Please enter the Number of basic service connections: ");
numBsSrvConecs = scan.nextInt();
when i enter the correct data ( c, C, d, D) it goes into infinite loop and never reaches the next keyboard scan for System.out.print("Please enter the Costumer Type C or R: "); -

Satellite A100 Keyboard input language does not match the physical keyboard
Sorry.
Actually this is the first row:
& é " ' ( - è _ ç * ) =
Regards,
Leonardo
I have a SATELLITE A 100 laptop (Model PSAARE-02X01TFR) with french (I think) QWERTY keyboard here and cannot figure out how to set it in Win XP.
It has these chars on top row:
(Numbers are shifted)
The second row has:
q w e r t y u i o p ^ $
The third:
q s d f g h j k l : ù *
The fourth:
z x c v b n m ; , !
Any idea what is it and how do i set it up???
Thanks, LeonardoHi!
As Akuma said you can change the keyboard input language in control panel. Its very easy and takes only one minute to change it.
Check this!
If you have more questions, please let us know!! :)
Bye -
I am looking for a way to put my gui application in a "wait state." What this entails is that the mouse cursor shows an hourglass and mouse clicks are ignored. Also, any keyboard activity is ignored as well. The reason for this functionality is that there are times that my program needs to perform cpu intensive work and I would like the user to wait until the work is complete before the gui becomes responsive again.
Now, I figured out how to ignore the input from the mouse by using adding a mouse listener to the GlassPane of the gui's JFrame and setting the GlassPane visible. But I can't find a way to use the GlassPane as a "buffer" between the user's keyboard input and the gui. The only alternative that I have found is to add a KeyListener to every component that can receive keyboard input but I would rather not have to manually add a new listener to every single button, textfield, and table that I might have added to the frame. Is there an elegant solution to ignoring or consuming all keyboard activity on a frame that is already set visible? Thanks for your responses.You know, if I read the entire message of the OP, I wouldn't look quite so dumb!
Take a look at the following. It will block and unblock keyboard input.
public class DispatchTest
KeyEventDispatcher blocker = null;
public JPanel buildPanel()
JPanel p = new JPanel(new FlowLayout());
p.add(new JTextField(20));
return p;
public void blockInput()
if (blocker == null)
blocker = new KeyEventDispatcher()
public boolean dispatchKeyEvent(KeyEvent e)
e.consume();
return true;
KeyboardFocusManager.getCurrentKeyboardFocusManager().addKeyEventDispatcher(blocker);
public void unblockInput()
if (blocker != null)
KeyboardFocusManager.getCurrentKeyboardFocusManager().removeKeyEventDispatcher(blocker);
public static void main(String[] x)
JFrame f = new JFrame();
DispatchTest t = new DispatchTest();
f.setContentPane(t.buildPanel());
t.blockInput();
f.pack();
f.setVisible(true);

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.
-sachitAlright, I'll post the 3 classes here.

Keyboard input delayed in Siebel application // letters lost while typing
Hi all,
We have a strange problem on a client computer. While working with Siebel, keyboard input is extremely delayed. When typing a word or a phrase, it takes some seconds to appear in the corresponding field, and also some chars are just lost if one is typing too fast. This does only happen in Siebel - all other applications are OK.
I have seen this already some months ago, but don't remember the cause.
Web Client 7.8.2.14 QF0E76
Win XP SP3 IE8
Did anyone ever experience this? Might be some specific driver issue or IE security update or whatever?
Thanks
BennyThanks Wilson for your input, unfortunately resetting browser settings and stuff like this does not help.
In the meantime I have done more research on this and found something interesting. The dropped characters / missing keystrokes do only appear when typing in Siebel popup applets. We do NEVER lose any keystroke when typing in a normal form or list applet. I have run a little test with a vanilla SRF file and a VBS Script.
I placed a VBS file on my desktop which will use SendKeys to simulate typing the word "Siebel" several times.
The source code of the VBS file is:
>
Option Explicit
Dim WshShell, c
Set WshShell = CreateObject("WScript.Shell")
c=0
WScript.Sleep 5000
Do While c < 5
WshShell.SendKeys "S"
WScript.Sleep 70
WshShell.SendKeys "i"
WScript.Sleep 40
WshShell.SendKeys "e"
WScript.Sleep 30
WshShell.SendKeys "b"
WScript.Sleep 90
WshShell.SendKeys "e"
WScript.Sleep 120
WshShell.SendKeys "l"
WScript.Sleep 70
WshShell.SendKeys " "
WScript.Sleep 90
c = c + 1
Loop
WScript.Quitwhen I click this script I have 5 seconds to switch to Siebel and point the cursor into a text field.
-> When this text field is on a form applet, it correctly writes "Siebel Siebel Siebel Siebel Siebel"
-> When this field is on a MVG applet, it sometimes drops keystrokes like "Siebel Siel iebel Siebel Sibel"
what the hell could be the problem ??????
Could someone try this in another environment??
We are on 7.8.2.14 QF0E76 ... -
Keyboard input stopped working on Solaris 11 Live x86 Toshiba R835 Notebook
I can boot, and keyboard input works for login, but does not work for xterm, terminal, Firefox, ... Mouse works for gparted and apps. It did work for 8 hrs but stopped. Any suggestions ?

(EE) Error loading keymap /tmp/server-0.xkm
I would be googling for that. E.g. see thread.
So did you update xkeyboard-config? It's tedious that you haven't had the sense yet to list which packages got updated, along with version numbers.
It's nice to see you enter here, brebs!
A few things have happened:
I just noticed that the file '/etc/X11/xinit/xinitrc' isn't present at all! It was present when I posted the thread (I think). So X didn't even start. I had to create .xinitrc in my home directory with single like 'exec xterm'. X started fine but keyboard still didn't work.
Out of nowhere, I thought of using nouveau drivers instead of Nvidia drivers. So I went ahead and switched to nouveau and bam - keyboard is working. Enabled GDM and keyboard is still working. I still would like know what went wrong with Nvidia - for educational purposes.
What more details should I provide? I'd like to have Nvidia drivers back.

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.

How to use multiple hierarchies for a single char in single query
Hi,
Is there any way that we can use multiple hierarchies for a single char in single query. I tried and it just allows me to select one hierarchy even if I use hierarchy variable.
I have a requirement where user wants to see information related to a cost center with different cost center groups in different hierarchies (every year has different cost center group hierarchies).
Suppose I want to see information related to a cost center from year 2001-2004.in these four year cost center may have been associated to different groups depending upon that year hierarchy. How can I do that?
Thanks
JonaNope. Now way to do this.
There is always just one hierarchy assigned to a characteristic. And even if the hierarchy was time dependent, it only reads it for one key date and not according to transaction data.
Regards,

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. -
How to use the phone's Mini-Keyboard Input with the 'Textbox'(MIDP2.0)?
(My apology. My English is not perfect but I'll try my best. >_<)
Hi. I'm trying to create a textbox(in my own little application) that is compatible with the mini-keyboard input feature.
This problem involved any device that have a built-in "mini-keyboard".
Problem:
I tried the 'Textbox' class from MIDP2.0 but the result, as expected, is like using the phones with no built-in keyboard.
(Forexample if I want to input the character 'C' inthe text box, I need to press number '2' button three times to let it circle through 'A' -> 'B' then 'C'. )
Then I tried entering URLs in the phone's built-in web browser, the result is I can use the mini keyboard to type like a PC keyboard.
Question: How do I implement such textbox that is fully compatible with the built-in mini Keyboard?
I tried browsing through the MIDP2.0 API but it seems the 'Textbox' class there couldn't do it.
Thank you. =)
/bow
Edit/Delete MessageThe textbox should have input just as any other normal phone input. If not, something strange is going on.
Anyway , there is no use to make your own input method, since every phone has another implementation of this anyway. It would only confuse users.
