Measure

I am going to read a barcode that contains two barcodes from a scanner, one is the UPC barcode, the other is a barcode with quantity. My barcode scanner is a USB simulating a keyboard. The reader provides a return key after each of the two codes. When I scan to the Notepad,it presents UPC code, a return character, the quantity and another return character. I am a Visual studio 2010 user in C#,I am trying using textbox to accepts returns and set to multilines, but there is no quantity barcode shows up, What should i do?

Do you use the click event in C#.NET when you generating the barcode?
You need to check the scanning system. And I am just wondering, why not put the quantity into the UPC barcode.

Does it work if increase the height of the TextBox? Try making it higher and scanning once again.

UPC-A printing is not easy, especially for those who knows little about barcode. Print UPC with a C# barcode generator.http://www.onbarcode.com/csharp/

wow.same name.  i have to say.UPC barcodes have fixed length with 12 digits. If I encode quantity in it, the length is extended. I try to increase the height of Textbox, but I don`t see any progress.

I know a C#.NET barcode reader library that may be in help. BTW, to read UPC-A barcode or UPC-E barcode images correctly, there's some requirements. Besides, checksum, data, the barcode size is also need to be concerned. So, please firstly make sure all your barcode settings during generation are compatible with its latest barcode specifications, like ISO/IEC or GS1 standards.
