• Bar code printed with Adobe Reader XI can be recognized by bar code reader

  Dear support,

  
  

  We generate barcodes and convert it into pdf file using Crystal Report for .NET Framework 2.0

  
  

  The pdf file opens with Adobe reader XI / FoxitReader 4.3.1. It is printed with Avery Dennison AP 5.4 300 dpi.

  
  

  When the pdf file is printed with Adobe reader XI, the barcode can be read with the code reader barcode, but when it is printed with FoxitReader 4.3.1 barcode can be read with the barcode reader.

  I compared the two codes barcode printed and found Adobe printed the thicker lines and larger characters. Thus, two lines pasted together and become a 1 line. As a result, it can be recognized by bar code reader.

  
  

  Could you explain why this happen and how to solve this problem in Adobe? Are there settings I can change to fix?

  
  

  Thank you very much.

  Operating system: Windows Xp or Windows 7

  
  Application: Adobe reader XI or FoxitReader 4.3.1

  I printed the label using Adobe Reader 11.0.06 and the bar code looks like absolutely perfect:

  

  I have also no problem scanning that bar code printed; It reads 00000000110001900631.

  So, in the end, I don't know what the cause of your side.  Can you try to print as Image (Advanced on printing Panel button)?

• Example of bar code reader does not work with daramatrix white on black

  I downloaded, built and installed the example of barcoderreader on a Z10.  I was very impressed by its ability to detect and decode codes data matrix.  However, most of our codes data matrix are then on a black background.  I found that the barcodereader would not detect them.  I looked at the camera SDK to see if there was a negative mode, but could not find one.  Is there anyway to make easier to read all about the black datamatrix codes?

  For this you probably want to look at the CustomBarcodeScanner (https://github.com/blackberry/Cascades-Samples/tree/master/custombarcodescanner)

  It shows you how you can implement your own scanner barcode using the camera of Cascades API and included ZXing library. From there it would be up to you as to how you detect actually reversed the barcode.  You might try to reverse the buffer overview before he gets to ZXing, or provide your own implementations of one of the classes it uses which makes the inversion (they are licened Apache open source) or find another approach.

  I don't know which would be the best way, but I'd be interested to hear how it goes.

• Problems with the bar code reader sample

  I want to integrate barcode scanner in my application, but it seems to be a lot more complicated than I thought.

  I use the example of BarcodeReader, and when I integrate his code 1:1 it works correctly.

  As soon as I try to change, however, is not.

  I want to:

  -use without a cover and an animation

  -have everything in a sheet with a close instead of a page button

  When I place "camera.open ()" in onCreationCompleted, for example, the camera is displayed as you wish, but the bar code scanner does nothing.

  I also tried to launch the camera delayed (of 200 or 400 MS) using QTimer::singleShot in c ++, the camera opens but still no scanning codes bar.

  A comment in the code example shows "Temporarily work around a bug", no idea if this could be related?

  This class is very buggy. You need to do initialization twice, the other after a delay of ~ 200 ms after the first. This makes the sample.

  I was able to make it work with the one-time initialization by defining the camera right after the creation of barcode detector:

  camera_ = new Camera();
  barcodeDetector_ = new BarcodeDetector(this);
  barcodeDetector_->setCamera(camera_);
  

  But if I change all the properties of the camera (such as the size of the viewfinder) during initialization or in viewfinderStarted() Manager of signal, it stops working and initialization of the double notch should be used to do work.

• Just opened new Adoge Edge v 20141, when I publish a simple test file, I get error code, reads "unsupported paths: / apple-touch-icon - precompressed.png, / apple-touch - icon.png"I did use all the images in my test file. "  Am I missing something?

  

  This has more to do with safari, rather than leading edge. For the time being users can try on Chrome (the question does not run on Chrome) while we face to fix/work around.

• QR code generator/reader air

  Someone at - he current recommendations for the generator of QR code reader (ANE, lib) and Air?

  I need a solution that is:

  (1) generate a QR/string text code in the Office of Air

  (2) generate a string of text/QR code in Air cross-platform mobile app (android or iOS).  The same code base as the #1.

  (3) scan the QR code on cross-platform mobile (android, iOS) go in my Air application.

  I see a lot of results in various ways, but so far nothing of cross-platform.

  Thank you!

  After dig deeper into the sample of AS3 in the Zxing library, I got it works fine on iOS and Android for generating and reading.  With the help of Air 3.5.

• Scanner of Code information bar appears automatically

  Hi all:

  I have a problem with a bar code reader, specifically Unitech AS - 10U.

  Now my problem is this, I am trying to create a sub.vi which accepts the entry of a bar code scanner as if entering the keyboard, make sure that information is the right length and make on to the next step in the sequence. When I use "Barcode Scanner.vi" (see attached vi) it works as a standalone vi no fine no problem, but when I integrate this sub.vi in my main.vi it stops working (even if I paste the entire content of the sub.vi in the main.vi). I found that by using the button "Highlight the execution" in the block diagram and to probe the input as if by magic string make present, however, without this, the input remains empty string (this works in all cases).

  So I tried to hit the forums and I came across "Prompt the user for Input" and it worked perfectly, only downside was that now I have to click on the OK button to accept the serial number I am trying to enter, so I changed to measure the length of the string and use that as the acceptance criteria to complete the while loop (see attached vi). Then bam, same problem, now it won't work unless I have the probe.

  Can someone help me and tell me what I'm doing wrong, I tried searching the forums and have not been able to find someone who had the same problem, I did.

  Thanks for taking the time to read my post, I appreciate it.

  

  That will solve most of the distress, then STOP voting! use a value change event and exit if the length of the string is 6 to 9 characters. (Turn off too much packaging).

• HP Officejet Pro e-all-in-8610: HP Officejet Pro 8610 - error Code: "0xc19a0013" (printhead missing or failed)

  I bought the printer (e-all-in-one printer HP Officejet Pro 8610) in January 2015.  The printer was working properly - fax, copy and scan, until two days ago.  Now, it doesn't print at all.  Received an error code: "0xc19a0013" (missing or does not have the print head).  An expanded version of the error code reads: "the print head seems to be missing, not detected, or incorrectly installed.  Error: 0xc19a0013.   The printer uses a removable printhead, HP Ink cartridges (black) 950 and 951 (cmy).  I used the diagnosis of HP support recommendations: all software and firmware for this printer is installed. HP ink cartridges are not low or empty; remove the printhead ink cartridges and reinstall them.

  There are several steps in the recommendation of troubleshooting, but I stopped to lift the printhead.  Because of my technical inexperience, and there were too many ceveats (attention, attention, proper relocation and etc..)  with the removal of the print head which could cause problems more serious.  Then, I stopped to remove and clean the print head.  Also, used the doctor to Scan printer HP for assistance. Tool to clean the printhead does not.   What worries me most with the 0xc19a0013 error code is his explanation: the print head seems to be missing, not detected, or incorrectly installed.  I can use all the help I can get to understand what is happening with the error code that I received and the resolution of the printer malfunction.

• TCP communication with barcode reader Keyence SR-1000 series

  So I have a client who needs help to connect the code reader barcode Keyence SR-1000 using TCP/IP to a LabVIEW application. After researching 'Connection 'document' of Keyence for TCP, I realize that it is based on their utility software alone.

  As I have no experience with barcode readers, I'd appreciate any advice on what to look for and how to implement a 'driver'-based on the VISA for this device. Or, in general, how are the best scanners of bar codes connected to LabVIEW.

  Thank you

  You must contact the manufacturer of the barcode reader and ask for documentation on TCP communication. Otherwise, the best you could do is to use a tool like WireShark to 'sniff' the TCP data and try to understand what the scanner data is read/write at their own software and try to reproduce it.

  There are many manufacturers/types of barcode scanners - some have their own drivers (DLL, for example) you can call, some use Ethernet/RS-232, some simply to emulate a keyboard and "type" characters of the barcode.

• Visa erroneous zero byte in reading series

  Hi all

  Trying to debug a problem that I have with a Labview2011 VI and the USB-485/2 device.

  The installer has been simplified to get the wire from port 1 to port 2 in a 2wire-auto configuration. As described here:
  http://digital.NI.com/public.nsf/allkb/D5CC369B3E3E6F0586256D1600563245

  and here:
  https://decibel.NI.com/content/docs/doc-4169

  Port 1 sends a message of 8 bytes by using visa / writing then begins a visa-reading of 8 bytes. (timed content in a loop of 10 Hz)

  Port 2 is configured in a single loop using the wait for event visa byte, then visa-read 8 bytes, connected directly to visa / entry.

  For 1 Port data transmitted, the data received and read visa error code are recorded on the disc.

  The success of installation passes are receives data without loss... so the back loop work...

  However! Occasionally, another zero byte is read from visa-reading the port1.

  Almost all the code read visa back operations "1073676294" port 1 (the number of bytes transferred is equal to the number of entries requested. More data may be available) which is very good. Even if sometimes the error code '0' is back (operation completed successfully). This "0" code seems to be associated with the extra byte in the receiver.

  This causes a problem because it throws the mismatch scheduled application command/response pairs.

  I tried many tariffs buad, visa-read timeouts and transmit frequencies, the problem remains. Adding a visa-flush buffer prevents the error from reproducing, but won't stop him intervened and upsetting the logic of command/response.

  Any ideas would be appreciated.

  If you send real binary data (which it looks like you are), you should have the off stop character.  Remember that reading VISA will be completed when the FIRST of the following: the desired number of characters is read, the character of endpoint found, there is a timeout.  So if there's a 0xA in your data, which will stop the read before that you would like it.
