For Using BC.NetBarcodeGenerator.Code39
Create Code 39 barcodes to raster image files, Stream, Bitmap, Graphics, and HttpResponse in .NET, C#, VB.NET applications.

Guide Overview

It's easy to use BC.NetBarcodeGenerator.Code39 library to draw and generate Code39 in your .NET/C#/VB.NET Class, Console Application, .NET Windows Forms, and ASP.NET web projects. Please firstly download and get the free trial library of BC.NetBarcodeGenerator.Code39. And the only thing for integration is to add your project reference to the library dll.

BC.NetBarcodeGenerator.Code39

PLEASE NOTE, BC.NetBarcodeGenerator.Code39 only supports creating Code 39 symbology for .NET applications. For creating all barcode symbologies, we provide BC.NetBarcodeGenerator.All that supports the most popular linear/1d barcodes and matrix/2d barcodes.

On this page, we provide C# and VB.NET Class coding examples of how to use BC.NetBarcodeGenerator.Code39 library to create Code 39 and save barcodes to a local raster image file and Bitmap object. In addition, you can also save Code 39 barcodes to Stream, Graphics, and HttpResponse in .NET applications.

In addition to creating barcodes in .NET Class, you can also create Code 39 in .NET Windows Forms, ASP.NET Web Forms, and IIS applications in other ways. Please click to see details. Moreover, ASP.NET web project and .NET Windows Forms project demos are included in our free trial package. Please download a free trial to see more.


Creating Code 39 in .NET/C#/VB.NET Class

1. This section shows how to create linear barcode Code 39 to a local raster image file on your disk in ASP.NET C# and VB.NET Class. Jpg, Jpeg, Tiff, Png, Bmp, and Gif formats are supported. Please firstly add your ASP.NET project reference to BC.NetBarcodeGeneratorTrial.Code39.dll.
