Data Matrix Barcode Introduction

Data Matrix, also named as ECC200 & 2D DataMatrix barcode, is a two-dimensional matrix barcode commonly used to mark small items. Being space-efficient, Data Matrix is recommended by American EIA for labeling small electronic components.

KeepAutomation VB.NET Data Matrix barcode generator supports Data Matrix barcodes generating in Visual Studio .NET Windows, Web applications, .NET Reporting projects.

The .NET Barcode Generator SDK also supports QR Code generating, Code 39 generating, Code 128 generating, PDF-417 generating, EAN-13 generating, GS1-128 generating, UPC-A generating in Visual Basic .NET applications.

Data Matrix in ASP.NET using VB.NET

Data Matrix barcode generation in ASP.NET web application can be realized with this barcode control, with which you can also generate Data Matrix barcode image in IIS. For detailed information, you may refer to this ASP.NET barcode creation tutorial in VB.NET.

Data Matrix in WinForms app using VB.NET

It is easy to generate Data Matrix barcode image in .NET WinForms with this mature VB.NET Barcode Creator Control. This VB.NET barcode generation guide in WinForms have described the operation steps in detail.

Data Matrix Encoding Character Set

KeepAutomation's software supports the following Data Matrix barcode data formats:

• ASCII: All ASCII characters, including 0-9, A-Z, a-z and special characters like $ , % + / : * etc
• Auto: KeepAutomation's software will select proper data format according to your encoding value
• Base256: to encode images, double-byte characters, binary data and 8 bit values
• C40: numeric digits 0-9, upper-case letters A-Z
• Edifact: 0-9, A-Z, many punctuation marks
• Text: 0-9, a-z
• X12: 0-9, A-Z, and some punctuation marks

With vb.net barcode generator, you can easily encode the above characters into Data Matrix barcode in Visual Basic .NET applications without any 3rd party software such as fonts, COM control, VBA, Macro programming.

Maximum size of Data Matrix characters in VB.NET

A single Data Matrix barcode can encode more than 1000 characters. You can view the details below. If you need encode more text, you could also choose Data Matrix Structure Append data mode.

• Alphanumeric data: up to 2,335 characters
• Byte data (8-bit): 1,555 characters
• Numeric data: 3,116 digits

If your Data Matrix data exceeds the maximum number of characters, the vb.net barcode generator software will automatically generate an empty image with text "Invalid Barcode Settings" printed.

Encode Data Matrix with Unicode text in VB.NET

Data Matrix does not support encoding Unicode text directly into barcode symbology. To do so, you can convert Unicode text to byte array data using UTF8 encoding, then encode byte array data to Data Matrix using Base256 data mode in your vb.net code.
