  I migrated the system from VB6 to VBNET.
  
  In VB6, we use the type of barcode is CODE128

  

  1184×533 35.8 KB

  In VBNET, the type of barcode is not available type of CODE128
  
  

  

  927×656 134 KB

  
  
  The result of migration when we use a type of Code_128_C is not mapped with the VB6 system
  
  This is the evidences
  
  VB6:

  Hi Nguyen,

  It seems like you are using different versions of ActiveReports, due to which you are observing the change in the barcode types. Please share with us both of your reports, along with the sample data to test them, so that we can look into them. Also, you may use the following barcode types based on the type of data that you are using:

  • Code_128_A: It uses control characters, numerals (0 to 9), punctuation, and upper case alphabets (A to Z)
  • Code_128_B: It uses punctuation, numerals (0 to 9), upper case, and lower case alphabets
  • Code_128_C: It uses only numerals (0 to 9)
  • Code_128auto: It uses the complete ASCII character set and automatically selects between Code 128 A, B and C to give the smallest barcode

  Hi Katyayny,

  It seems like you are using different versions of ActiveReports=> Yes, VB6 is active report 1.5j and VBNET is active report 14j
  
  I give you the sample data to test them: 001

  I am using the Code_128_C of the barcode type.
  
  But I use the device to scan this barcode the the result of VB6 and VBNET is
  
  VB6: 001
  
  VBNET: 0001

  I attach the report file of VB6 and VBNET:

  VB6: rptDVBarCode.zip
  
  VBNET: rptDVBarCode_VBNET.zip
  
  Please help me to check again.
  
  Thank you very much

  Hi Nguyen,

  Code_128_C is a numeric-only barcode type that is encoded in pairs and will add a zero to the beginning of the data if there is an odd set of numbers because it requires that an even set be used.

  I would suggest you use Code_128auto to resolve your issue, as it will automatically select between Code 128 A, B, and C to give the smallest barcode.

  You may also refer to the following Stackoverflow thread regarding the same:

  Hope this helps!
