Writing Barcodes

Start Visual Studio .NET.
Start with the project that you created in Reading Barcodes Tutorial

Drag and drop a new button in Form1. Change the following properties:

Property	Value
Name	writeBarcodeButton
Text	Write barcode

Add the following code to writeBarcodeButton click procedure:

[Visual Basic]


             Private Sub writeBarcodeButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles writeBarcodeButton.Click
                If theImage Is Nothing Then
                   Return
                End If
            
                ' Create a UPC A barcode
                Dim data As New BarcodeData()
                data.Symbology = BarcodeSymbology.UPCA
                data.Value = "01234567890"
                data.Bounds = New LogicalRectangle(10, 10, 600, 200, LogicalUnit.Pixel)
            
                ' Setup the options to enable error checking and show the text on the bottom of the barcode
                Dim options As New OneDBarcodeWriteOptions()

                Try
                   ' Write the barcode
                   barcodeEngineInstance.Writer.WriteBarcode(theImage, data, options)

                }
             }

Build, and Run the program to test it. Click "Load Image" to load the image and "Write Barcode" to write a 1D UPC A barcode to the image and save it.
