ASP.NET Barcode Reading FAQs:

1. Difference between the trial version and full version
There is no functional difference.
However, for trial package only, the first character in barcode value is RANDOMLY generated.
And according to the evaluation license agreement, developers are not allowed to distribute software using a trial version of .NET Barcode Reader.
2. How to start barcode decoding for ASP.NET?
It is a simple task to recognize barcode from image in ASP.NET web applications.
  1. Add BarcodeLib.BarcodeReader.dll into your .NET project reference.
  2. Tell BarcodeReader class where is the image file, and what's the barcode type.
Here is the sample code:
     string[] datas = BarcodeReader.read("C:/YourBarcodeImage.gif", BarcodeReader.CODE39);
Pass your barcode image file, and barcode type to BarcodeReader, and it will return barcode datas.
If there are more than one barcode in the image file, the returned String array size will be more than 1.
3. How to scan & return supplement barcode data?
For barcode EAN 8, EAN 13, UPC-A, UPC-E, their barcode image may contain 2 or 5 digits supplement barcode, ASP.NET Barcode Reader Control will add supplement barcode data to the main barcode data.
For example, ASP.NET Barcode Reader Control will output data as "123450512345" for above sample image. The First 7 digits "1234505" is UPC-E data, and the last 5 digits "12345" is UPC-E supplement data.
4. More details about UPC-E barcode data
For UPC-E barcode, usually there are 8 digits printed on the barcode label. The first digit is UPC-E number system, valid values are 0 or 1. The next 6 digits are UPC-E data, and the last one is checksum.
Our library will return 6 digits data and the last one checksum. Developer should use the first 6 digits as UPC-E data, according to UPC-E specification.
For the above barcode image, 0 is the number system, 123450 is the UPC-E data, and 5 is the checksum. Our library will return 1234505, plus suppliment barcode 12345. So the final output will be 123450512345.
