I want to limit the number of scan done by a barcode scanner to 50, how can i do that

I am scanning data from my 2d barcode scanner, now i want that after 50 scans my barcode scanner should prompt that scanning of 50 barcode complete, how can i do that? i know logic might be easy but its not sticking me. Please help.

Hey,
Everytime you get a valid scan increment a counter and compare with 50. If limit is reached you are done.

  • Let's say I have a document that is 5 pages long. Now I want to insert the page numbers, starting on page 3 with the number "3" and leaving out pages 1 and 2. How do I do that?

    I just found the answer myself. I don't know how to delete my question, so I'll just write the reply to the answer - just in case somebody needs to know: Insert a section brake after the second page and then choose "Start on 3".

  • I have a Mac Pro with four hard drives. I currently have Lion installed on one hard drive. I want to have the option to boot from either Lion or Snow Leopard. How can I do this?

    I have a Mac Pro with four hard drives. I currently have Lion installed on one hard drive. I want to have the option to boot from either Lion or Snow Leopard. How can I do this?

    It's best to install Snow Leopard on one of the three remain drives without an Operating System.
    You can then install the applications you need from the original media. Create a User Account using Setup Assistant.
    Do you want to migrate User Accounts from the OSX LIon boot drive, or are you keeping the User Accounts separate?
    Dual-booting just requires holding the option key during startup and selecting either Lion or Snow Leopard.

  • I want to set the IP address back to default on a HP LJ 4000n how do I do that?

    I want to set the IP address back to default on a HP LJ 4000n how do I do that?  The I/O would not let me or maybe just don't know how.

    to do that, power off the printer and then press the Select button and power on, maintain the select button during start up.
    But after that, I don't know how to setup a new IP adress

    You can't.
    And advertising that you are breaking the rules with your account here in public just alerts Apple that they have a user who believes that the rules don't apply to them.

    the information of photo like date change after close it. How can'i correct that?

    Using the Photos ➙ Batch Change ➙ Date menu option will let you change the EXIF Capture Date of the photo.
    For a single photo (or to set a group of photos to the same date and time) use the Photos ➙ Adjust Date and Time ... menu option.

    Use the Settings app tO check what's in your email account information.
    Ssettings > Mail, Contacts, Calendars > Tap on your email account > in the Account Information is your name or your husbands name listed in the first line?
    if your husbands name is there change it to your name.

  • How do I limit the number of characters allowed in an input form and then how do I limit the number of lines?

    I'm selling Classified Advertising in a newspaper and I want my visitor to be able to enter their own ads.
    They need to be limited to 30 characters/line with a limit of 4 lines.  (120 characters total).
    How can I use html or css to limit the input to 30 characters per line and then limit them to 4 lines?
    Is that possible?
    Thanks so much.
    Dale

    I would place 4 text fields and use the maxlength attribute. Setting maxlength="30" will stop any more than 30 characters from being entered into any given text field...
    <p>
      <label for="textfield">Line 1:</label>
      <input type="text" name="textfield" id="textfield" maxlength="30">
      <br>
    <label for="textfield2">Line 2:</label>
      <input type="text" name="textfield2" id="textfield2" maxlength="30">
      <br>
    <label for="textfield3">Line 3:</label>
      <input type="text" name="textfield3" id="textfield3" maxlength="30">
      <br>
    <label for="textfield4">Line 4:</label>
      <input type="text" name="textfield4" id="textfield4" maxlength="30">
    </p>

  • I am giving my old macbook pro to my mother as a present, and i want to change the itunes account to hers, with none of my music there. how can i do this?

    how can i change accounts to make it like completely empty for her?

    Follow these instructions step by step to prepare a Mac for sale:
    Step One - Back up your data:
           A. If you have any Virtual PCs shut them down. They cannot be in their "fast saved" state. They must be shut down from inside Windows.
           B. Clone to an external drive using using Carbon Copy Cloner.
              1. Open Carbon Copy Cloner.
              2. Select the Source volume from the Select a source drop down menu on the left side.
              3. Select the Destination volume from the Select a destination drop down menu on the right
                  side.
              4. Click on the Clone button. If you are prompted about creating a clone of the Recovery HD be
                  sure to opt for that.
                   Destination means a freshly erased external backup drive. Source means the internal
                   startup drive.
    Step Two - Prepare the machine for the new buyer:
              1. De-authorize the computer in iTunes! De-authorize both iTunes and Audible accounts.
              2, Remove any Open Firmware passwords or Firmware passwords.
              3. Turn the brightness full up and volume nearly so.
              4. Turn off File Vault, if enabled.
              5. Disable iCloud, if enabled: See What to do with iCloud before selling your computer.
    Step Three - Install a fresh OS:
         A. Snow Leopard and earlier versions of OS X
              1. Insert the original OS X install CD/DVD that came with your computer.
              2. Restart the computer while holding down the C key to boot from the CD/DVD.
              3. Select Disk Utility from the Utilities menu; repartition and reformat the internal hard drive.
                  Optionally, click on the Security button and set the Zero Data option to one-pass.
              4. Install OS X.
              5. Upon completion DO NOT restart the computer.
              6. Shutdown the computer.
         B. Lion and Mountain Lion (if pre-installed on the computer at purchase*)
             Note: You will need an active Internet connection. I suggest using Ethernet if possible because
                       it is three times faster than wireless.
              1. Restart the computer while holding down the COMMAND and R keys until the Mac OS X
                  Utilities window appears.
              2. Select Disk Utility from the Mac OS X Utilities window and click on the Continue button.
              3. After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click
                  on the Erase tab in the DU main window.
              4. Set the format type to Mac OS Extended (Journaled.) Optionally, click on the Security button
                  and set the Zero Data option to one-pass.
              5. Click on the Erase button and wait until the process has completed.
              6. Quit DU and return to the Mac OS X Utilities window.
              7. Select Reinstall Lion/Mountain Lion and click on the Install button.
              8. Upon completion shutdown the computer.
    *If your computer came with Lion or Mountain Lion pre-installed then you are entitled to transfer your license once. If you purchased Lion or Mountain Lion from the App Store then you cannot transfer your license to another party. In the case of the latter you should install the original version of OS X that came with your computer. You need to repartition the hard drive as well as reformat it; this will assure that the Recovery HD partition is removed. See Step Three above. You may verify these requirements by reviewing your OS X Software License.

    You can deauthorise all 5 at once, then reauthorize the one you want.
    Learn how to authorize or deauthorize your computer with your Apple ID.
      http://support.apple.com/kb/HT1420
    You need to log into iTunes on the computer you want to deauthorise. Otherwise, contact contact iTunes Store support to see if they can help.
