Scan, Read Code 39 barcodes from images is one of the barcode reading functions in
.NET Barcode Reader SDK control. It is compatible for Microsoft Visual Studio .NET framework 2.0 and later version. VB.NET barcode scanner is a robust and mature .net barcode recognition component for VB.NET projects. You can easily scan and decode linear, 2d barcodes from image documents in your VB.NET class, console application, ASP.NET web projects, and VB.NET Windows software.
To help .net developers easiy integrate barcode reader control into your .net projects, we provide detailed online tutorial for
VB.NET Barcode Scanner component supports scanning and reading 20+ linear, 2d barcodes, including
Call BarcodeScanner.Scan() method in your VB.NET class, and pass your barcode image file, and Code 39 barcode type (BarcodeType.Code 39) as method parameters.
What is Code 39 barcode used for?
Code 39, also known as Code 3 of 9, was the first barcode to encode both numbers and letters. It is most commonly used in
the inventory, government, military and electronics industries.
Using VB.NET barcode reader library, you can easily scan and recognize Code 39 text from barcode images in VB.NET class library, console, WinForms, WPF Windows apps.
What is the Code 39 on a barcode reader?
Code 39 is a 1d barcode symbology that encodes up to 43 characters, including uppercase letters, numbers, and special symbols.
Code 39 extension supports encoding full 128 ASCII characters.
Using VB.NET Barcode Scanner library, you can scan and decode all 128 ASCII characters from Code 39 and Code 39 extension barcode images in VB class in Windows applications.
To scan and decode Code 39 text from a barcode image, a barcode scanner device or reader software will scan all bar and space modules on the Code 39 barcode symbology,
and use a character map to translate the bar and space groups into Code 39 data characters.
OnBarcode VB.NET Barcode Scanner library will help VB developer quickly integrate Code 39 barcode scanning and reading features in a VB.NET class, WPF, WinForms Windows application.
What is the difference between Code 39 and Code 128 barcodes?
Code 128 requires a checksum. If the Code 128 barcode is damaged, it may still be scannable. Code 39 checksum is optional.
If the Code 39 barcode without checksum is damaged, it won't be scannable.
In VB.NET class, you can scan, recognize and decode both Code 128 and Code 39 barcode data from image files using VB .NET Barcode Reader library.
