Codebar reader VS Keyboard

Hi,
I am using a codebar reader that transforms the code number
into keyEvents. The problem is that i need to seperate beetween the input from the codebar and the input from the keyboard.
The codebar sequence starts with Skift+Ctrl+ E and ends with Enter, i need to take the numbers in between to get infromation about the item. How can modify keyListener or some other interface so it distinguish between a codebar sequence and a regular input from the keyboard, sence it all seems the same.

I the listner have it look and see if it matchs the shift ctrl ket pattern you mentioned. Of course if the user presses the same key sequnce on the keyboard there is no way of telling the differnence. You could always examine the input stream, I assume it is serial....

Non-Blocking call to read the Keyboard

does anyone know how to make a JAVA program make a non-blocking call to read the keyboard? eg. write a program which generates prime number until a keyboard key is pressed.

if you use a gui you can use keyListener
Would work only if your gui elements have focus right now.

Show Reading List keyboard shortcut does not work

The Show Reading List keyboard shortcut (shift-command-L) does not work in Lion Safari 5.1.

Problem has been fixed. I reported the bug to Apple from the Safari menu. Also, I had a different application that used the same keyboard shortcut for one of their hotkey's which I disabled. Then it worked fine. Shift-Command-L now shows reading list in Lion.

How do you identify a key events source (std keyboard or a USB barcode reader emulating keyboard)?

I have attached a USB barcode reader which essentially emulates a USB
keyboard. Having looked through the VC++ V5.0 documentation and some SDK
documents that I have, I could not find a library function that identifies
what device sourced the keyboad event.
Does know if this is possible ? Anyone have any ideas ?
Thanks.

If you over ride the "CWnd:reTranslateMessage" function you'll be able to trap keyboard messages.
ex:
BOOL CTestexecDlg:reTranslateMessage(MSG* pMsg)
if (pMsg->message == WM_KEYDOWN && (pMsg->wParam == 13 || pMsg->wParam == VK_ESCAPE))
// Enter or escape key was pressed; return TRUE to stop default handling
return TRUE;
if (pMsg->message == WM_KEYDOWN && pMsg->wParam == 0x30)
BringWindowToTop( );
return TRUE;
if (pMsg->message == WM_KEYDOWN && pMsg->wParam == 0x31 && m_DisplayObject1 != NULL)
// Enter or escape key was pressed; return TRUE to stop default handling
m_DisplayObject1->SetWindowToTop( );
return TRUE;
if (pMsg->message == WM_KEYDOWN && pMsg->wPa
ram == 0x32 && m_DisplayObject2 != NULL)
// Enter or escape key was pressed; return TRUE to stop default handling
m_DisplayObject2->SetWindowToTop( );
return TRUE;
if (pMsg->message == WM_KEYDOWN && pMsg->wParam == 0x33 && m_DisplayObject2 != NULL)
// Enter or escape key was pressed; return TRUE to stop default handling
m_DisplayObject3->SetWindowToTop( );
return TRUE;
return CDialog:reTranslateMessage(pMsg);

Adobe Reader 9 keyboard shortcuts broken?

The zoom in and zoom out keyboard shortcuts (CTRL "+" and CTRL "-")that have been working since forever have now stopped working! It seems somewhat inexplicably as CTRL + NUMPAD 0 and CTRL + NUMPAD 1 now have those functions.
What is going on? What did the software designers think? Where can you customize your keyboard shortcuts to get the old, logical ones, back?
Grateful for any thoughts.

I'm quite angry, too. I used to use CTRL+1 to zoom to 100% very, very often. Now CTRL+1 zooms out and even worse, there's no new shortcut for zooming to 100%. I'm forced to switch to mouse now which costs really much time. Who came up with this stupid idea?

Simple Question: How do I read from keyboard?

How do I read characters or integers from the keyboard?
InputStream with try/catch?
Can someone write code to show me how?

play with this a little...
it has the basics,
best i can do right now...
import java.io.* ;
import Car ;
class MilesPerGallon
public static void main( String[] args )
      throws IOException
    BufferedReader userIn =
        new BufferedReader(
        new InputStreamReader( System.in ) );
    String line;
    int    startMiles, endMiles;
    double gallons;
    System.out.println("Enter first reading:" );
    line = userIn.readLine();
    startMiles = Integer.parseInt( line );
    System.out.println("Enter second reading:" );
    line = userIn.readLine();
    endMiles = Integer.parseInt( line );
    System.out.println("Enter gallons:" );
    line = userIn.readLine();
    gallons = Integer.parseInt( line );
    Car car = new Car(
        startMiles, endMiles, gallons );
    System.out.println( "Miles per gallon is "
        + car.calculateMPG() );

Logic reads my keyboards white keys and black keys and vice versa

Logic is reading my Alesis Photon25 keyboard wrong. Pressing the white keys on my keyboard result in the black keys being activated in the transport window. For example, pressing C4 registers as C#4, and pressing C#4 registers as D4. Is there a way to solve this? Thank you in advance.

Try it in Garageband. If it does the same thing, then you've changed a transposition value within the keyboard.
If it only happens within Logic, check to see you haven't got any transposition values with the environments click&ports layer, and on any MIDI thru parameters.

Disc Read Error, Keyboard unresponsive

After attempting to install Windows XP I have gotten the seemingly common Disc Error. The larger problem is that my wireless keyboard is unresponsive so I can not "Press any key to restart" or hold option to boot. I have even gone the length of purchasing an Apple Wired keyboard and I still can not get it to work. The system was purchased new about 6 months ago. Any help would be greatly appreciated.

I had problems installing Windows XP before but after unplugging extra stuff from USB & Firewire ports like external harddisks and printer the installation worked.
What kind of mac do you have if my suggestion don´t work.. by holding down the power button usually works to get computer to reboot. And then by pressing down the "Option" - key button you get to choose OS. Hope this is a answer.

USB device reads as keyboard for set up

I am trying to use a wireless presentation remote that is supposed to be pc/mac compatible. When I plug in the usb connector, the "add a keyboard" menu appears. How do I add this device to my computer's preferences?

Hello,
I have used the Kensington USB remote with my Powerbook G4 for several years with no problems. When the "add a keyboard" menu appears, simply follow the directions there (I forget what the directions say exactly) and you should be fine.
However, if you have moved to X.5.1, then this remote seems to not be working. For me and for many others it is giving kernel panics when the USB dongle is inserted after the upgrade to x.5. Some have mentioned partial success (no crashes) when the USB dongle is inserted when the laptop is asleep.
A search of these forums with Kensington AND remote as keywords may provide additional helpful hints.

Reader X & keyboard shortcuts

Hello,
I use the Babylon software when reading to help me to translate some terms.
The shortcut I set in this purpose is Ctrl + right click on the word.
But that doesn't work in Adobe Reader X. Could it prevent Babylon to catch the shortcut ?
I have this problem only in Reader X.
Thanks.

Hello Friend Here is Solution.
Go to Edit ---> Preferences (Ctrl+K) In General Tab Uncheck Enable Protected Mode at startup. Restart Adobe reader Now it'll Work.

Firefox seems to be reading my keyboard as french...as in, my question mark is É...

I assume it is because I am in Canada, but it is really annoying. How do I change it to US EnglishÉÉÉÉ
And no, it isnèt my keyboard settings. All my other applications are fine.

The prime suspect is an extension. Could you review your installed extensions on the following tab and disable ALL nonessential, recently added, and unrecognized extensions? Then restart Firefox and test again:
orange Firefox button (or Tools menu) > Add-ons > Extensions category

How to read the keyboard of a smart phone with labview mobile?

The subject about says it all. I have an HTC phone with keyboard that is running WM 6.1. Using key events I can catch the left and righ soft keys and the left-right-up-down cursor movements, but it doesn't see the keyboard.
Mike...
PS: as a side note... given that Microsoft has signalled that it is pretty much abandoning the WM platform due tio lack of acceptance, I wonder what NI is going to do for mobile applications?
