To scan and recognize UPC-A barcode image from .NET windows and web applications, even a WPF project, you may need a control library for .NET barcode reading. The pqScan .NET Barcode Scanner is such a good library. From page .NET Barcode Reader Library, you can get all barcode recognition features that our software provides. And on this page, we will only talk about UPC-A linear bar code recognition.
Advanced UPC-A bar code scanning features are well compiled into a small and strong-named dll library, called pqScan.BarcodeScanner.dll. By adding this dll into your Visual Studio .NET, C#, VB.NET WinForms or web program, you can directly use all linear barcode reading features it provide, such as reading UPC-A barcode from rotated image (180 degree), returning the array of UPC-A barcode value at fast speed, recognizing all UPC-A barcodes at a time, etc.
We provide several APIs for performing UPC-A symbol scanning and reading in .NET desktop and ASP.NET site projects. If you want to use these APIs, please firstly make sure your developing environment is under Windows system. And your computer should install .NET Framework 2.0 version or above. Our Barcode Reader Software for .NET supports programming in Visual C# and Visual Basic .NET programming language.
