DataMatrix with special characters

VCL TMS VCL UI Pack
1

Good afternoon,
to create my datamatrix code i use TTMSFNCWXBarcode setted with barcodetype to bciDataMatrix.

There's a way to insert into the datamatrix any special characters as return / line feed ecc ?

I need to insert

  1. code
  2. enter
  3. value
  4. enter

like this
979323060 + #13 + 20 + #13

What is created by component is (with GetBarcode('979323060' + #13 + '20' + #13))

image

but when i read it (Zebra DS2208) i got

97932306020

but the result must be

979323060
20

Any suggestion ?

Thank you for the attention

Best regards
Daniele

Hi,

It's a bit unclear what goes wrong. We tested this here but the datamatrix we got is the following:

image
image207×153 667 Bytes

And it correctly decodes to:
979323060
20

The code is nothing more than

TMSFNCWXBarcode1.GetBarcode('979323060' + #13 + '20' + #13);

Would it be possible to send us a sample project that has this issue? Perhaps you have other settings enabled that we didn't try.

Good afteroon Tünde,
this
TMSFNCWXBarcode1.GetBarcode('979323060' + #13 + '20' + #13);
is what i do .... and i got, as result, the datamatrix i sended.
But i have the bad result when i read the code.
I think that is a bad reader configuration and is not so easy to get the rigth configuration.
I use Zebra reader model DS2208, if you have the same model can you share the correct ADF to read in order to fox it?
If you have another reader, can tell me the brand and the model ?

Thank you so much.

Best regards

Hi,

It's certainly not on the reader, the 2 produced barcodes are different. Scanning yours gets a different result from ours.
Did you select the bciDataMatrix BarcodeType? Do you have any other non-default settings applied to the component?

Good morning Tünde,
yes i did ....
The component has all properties setted as "component default" and (bottom) the setting as in the project.

object BarCode2: TTMSFNCWXBarcode
    Left = 47
    Top = 222
    Width = 235
    Height = 113
    ParentDoubleBuffered = False
    DoubleBuffered = True
    TabOrder = 2
    Visible = False
    AutoClearCache = True
    BarcodeType = bciDataMatrix
    LibraryLocation = llOffline
    Scale = 2
    Text = '123456'
  end

If possible, can you attach your datamatrix in order to test my reader ?

Thank you so much for your help.

Best regards
Daniele

Hi,

Please see attached project that we used for testing. It also contains the output datamatrix.
Do you get a different result if you run this?
barcode.zip (7.2 KB)

Good afternoon Tünde,
no way ....
I runned the project and .... i got the same result.
I think that the problem is inside the reader.
Even Zebra support is in trouble.

I'm ready to do some test with the your reader; Can you give me brand name and model ?

Thank you so much for your help.

Best regard
Daniele

PS: I'm out of office till 15/10/2026, so i'll can answer after that date .... sorry

Hi,

We used an android scanner app and a website too to test with, we do not have a physical reader. The android application actually was able to read your inital datamatrix but it had 2 linebreaks between the lines.
Based on this, it might indeed be something in your scanner related to linebreaks. Perhaps there's a setting somewhere that needs to be enabled or it expects the linebreak in a certain format?
Please see your private messages, I sent you an incremental source update that handles #13 and #10 correctly (\r and \n respectively for encoding).
