How to Encode GS1 Barcode Using VB.NET Class Codes
Top
VB.NET barcode encoding control owns the GS1-compatible data encoding function, so it can easily export & display these GS1 compatible barcode images encoding numbers with VB.NET scripting. Please install the barcode plugin by adding it to reference and toolbox first.
The following example text string will illustrate how to use VB.NET class codes to encrypt those GS1-compatible barcodes (GS1 DataBar, EAN-128/GS1-128, ITF-14, Data Matrix, and QR Code). Default value is Png, while you can output image in Gif, Jpg, Tif via VB.NET.

Generate GS1 DataBar Barcode in VB.NET Class


Dim gs1_databar As New Linear()
gs1_databar.Type = BarcodeType.RSS14
gs1_databar.Data = "01666663333300"

' GS1 DataBar Size Settings
gs1_databar.UOM = UnitOfMeasure.PIXEL
gs1_databar.X = 2
gs1_databar.Y = 82
gs1_databar.LeftMargin = 20
gs1_databar.RightMargin = 20

' GS1 DataBar Image Format Setting
gs1_databar.Format = System.Drawing.Imaging.ImageFormat.Gif

' Save GS1 DataBar to C:\
gs1_databar.drawBarcode("C://vb-net_gs1_databar.gif")

Generate GS1-128/EAN-128 Barcode in VB.NET Class


Dim gs1_128 As New Linear()
gs1_128.Type = BarcodeType.EAN128
gs1_128.Data = "(8101)06789900799"

' GS1-128/EAN-128 Size Settings
gs1_128.UOM = UnitOfMeasure.PIXEL
gs1_128.X = 1
gs1_128.Y = 80
gs1_128.LeftMargin = 10
gs1_128.RightMargin = 10

' GS1-128/EAN-128 Image Format Setting
gs1_128.Format = System.Drawing.Imaging.ImageFormat.Png

' Save GS1-128/EAN-128 to C:\
gs1_128.drawBarcode("C://vb-net_gs1_128.png")

Generate GS1 Compatible ITF-14 Barcode in VB.NET Class


Dim itf_14 As New Linear()
itf_14.Type = BarcodeType.ITF14
itf_14.Data = "1061414199993"

' ITF-14 Size Settings
itf_14.UOM = UnitOfMeasure.PIXEL
itf_14.X = 1
itf_14.Y = 76
itf_14.N = 2F

' ITF-14 Bearer Bar Settings
itf_14.BearerBarHori = 2
itf_14.BearerBarVert = 2

' ITF-14 Image Format Setting
itf_14.Format = System.Drawing.Imaging.ImageFormat.Png

' Save ITF-14 to C:\
itf_14.drawBarcode("C://vb-net_itf_14.png")

Generate Compatible Data Matrix Barcode in VB.NET Class


Dim data_matrix As New DataMatrix()

' Set Data Matrix barcode data to encode
data_matrix.Data = "(8101)06789900799"

' Set Data Matrix data mode
data_matrix.DataMode = DataMatrixDataMode.ASCII

' Data Matrix format mode
data_matrix.FormatMode = DataMatrixFormatMode.Format_16X16

' Set Data Matrix to be GS1 Compatible
data_matrix.FNC1 = FNC1.FNC1_1ST_POS

' Set Data Matrix barcode size;
data_matrix.UOM = UnitOfMeasure.PIXEL
data_matrix.X = 4
data_matrix.LeftMargin = 8
data_matrix.RightMargin = 8
data_matrix.TopMargin = 8
data_matrix.BottomMargin = 8

' Generate Data Matrix and encode it to gif format
data_matrix.ImageFormat = System.Drawing.Imaging.ImageFormat.Gif
data_matrix.drawBarcode("C:\vb-net_data_matrix.gif")

Generate Compatible QR Code Barcode in VB.NET Class


Dim qr_code As New QRCode()

' Set QR Code barcode data
qr_code.Data = "(8101)06789900799"

' Set QR Code data mode
qr_code.DataMode = QRCodeDataMode.Auto

' Set QR Code to be GS1 Compatible
qr_code.FNC1 = FNC1.FNC1_1ST_POS

' Set QR Code barcode size;
qr_code.UOM = UnitOfMeasure.PIXEL
qr_code.X = 4
qr_code.LeftMargin = 16
qr_code.RightMargin = 16
qr_code.TopMargin = 16
qr_code.BottomMargin = 16

' Save created QR Code to png file format
qr_code.ImageFormat = System.Drawing.Imaging.ImageFormat.Png
qr_code.drawBarcode("C:\vb-net_qr_code.png")
How to Encode Unicode into Barcode Using VB.NET
Top
Besides encoding ISO 8859-1 standard data, Onbarcode.com's VB.NET barcode encoder can also encode other data, such as Arabic, Cyrillic, Greek, Hebrew. And users can encode these special characters through the Unicode encoding function of our VB.NET Barcode Generator.
The following VB.NET codes are used to encode Unicode into two-dimensional barcode symbology QR Code, Data Matrix and PDF417. For more, you can input VB.NET code to change barcode height, color and other properties.
Please note that, the following VB.NET code uses Base64[] conversion method to encode Unicode. Therefore, to scan and obtain original data, you need to convert the decoded data back to original data via Base64[] conversion.
