PDF417 reading slowly

PDF417 reading slowly

This question is answered

We have a client that uses WAPRO3 with WA9212-G1 and he is saying that the time of presentation of the data after the reading of PDF417 codes is very slow.
It uses a web application, where data is read in the fields of Internet Explorer.
The client made ​​a little test, it performed the Demo Scanner software and this data is displayed instantly while IE takes longer than 8 seconds, because the data are presented character by character.
How is this a feature of your browser? Or is there some setting so that the data are presented in the same way the Demo Scanner?

Thank you.

Thanks!

    As you guessed the SHIFT key got raised 5 times, which , as you reported, turns on the Sticky Keys feature.

    Food for thoughts:
    Have you considered turning off the Sticky Key option?

    E.g.

    vvvv

    It´s look like that the barcode are not overwritten with the new barcode - do you have some experience with this?

    I'm afraid not Sad

    @All

    Feel free to share your toughts...

    vvvv

    Now with regards to your last RDP remarks, as you guessed, the RDP session only receives the CTRL+ V characters, the "Scan and paste" program sends to paste the contents of the clipboard (I.e. the barcode data, the "Scan and paste" program previously copied to the clipboard).

    Food for thoughts:
    Have you tried disabling the Do not allow clipboard redirection group policy.  

    vvvv

    Kind regards,

  • Good morning Wander,

    Could your customer give one of the below programs a try and let us know if it helps?

      Scan And Paste Console App [CF 2.0 - CE 5.0] (compressed)

      Scan And Paste Console App [CF 2.0 - WM6.x] (compressed)

    Installation instructions and use:

    • Save and decompress the above attached file
    • Copy all its files to your Windows CE 5.0 or Windows Mobile 6.x device
    • Launch the ScanAndPasteConsoleApp.exe program

      From that point on, the default scanner wedge program will be superseded and every time a barcode is read, its data will be copied to the device clipboard and automatically pasted to the foreground application (the one that has the keyboard input).

    • To stop this program, execute CloseScanAndPasteConsoleApp.exe.

    Regards,
    Jacques

    & For your information, « Copy and Paste » of scanned data will soon be the default mechanism for wedging.

  • Hi Jacques!

    I'm not able to download the file:
    Scan And Paste Console App [CF 2.0 - WM6.x] (compressed)  - The message "Group not found."
    Let's test version for CE and soon I return.

    Thanks!

  • Wander,

    Thanks for bringing this issue to my attention. I went ahead and fixed it.
    You should now be able to download the Scan And Paste Console App [CF 2.0 - WM6.x] file.

    Sorry about that.
    Kind regards,

    Jacques

  • Hello Jacques,

    i have a next problem. Our costumer have Workabout Pro 3 with Windows CE 5.0 and Citrix Client. He have barcodes with 5 BIG ENDIAN "GTH01-0510AA00" now he scan this barcode and on the citrix server side he get the information if he want to activate "Stick Key" - 5 x SHIFT you get a message. Now i know that the WAP generate for every scanned character a own event so i think WAP send the following after scanning the barcode:

    SHIFT + g + SHIFT + t + SHIFT + h + 0 + 1+-+0+5+1+0+ SHIFT + a + SHIFT + a + 0 + 0

    Is that correct?

    Now we see we get 5 x SHIFT and now Windows Citrix Server think we want to make a Stick Key and it popups. 

    We tested now with your software "Scan and paste" and this problem "StickyKeys" doesn´t longer exist :) but when i use your software via citrix client then i can scan the barcode and it function but when you scan the next barcode you get the barcode before. It´s look like that the barcode are not overwritten with the new barcode - do you have some experience with this?

    Other phenomen if i use your software and make a RDP session and use your software i get only after scanning a barcode this "v" instead of scanned barcode. I think of copy and paste - "STRG + v" do you know what i must configure that i get the barcodes instead of "v"?

     

    Long text - sorry for my bad english.

     

    Thank you

    Andreas
