VB.NET Code 128 Barcode Scanner SDK DLLs
The dlls from VB.NET Code 128 barcode scanner SDK are compacted into small-size libraries and can be integrated into VB.NET document image processing applications by adding reference directly. What should be noted here is that as this VB.NET Code 128 barcode reader control is only an add-on from RasterEdge
DocImage SDK for .NET. Therefore, you can use this Code 128 barcode reading function in your VB.NET project after you buy .NET Image SDK Core DLL license, as well as .NET Barcode Reader Add-On license.
VB.NET Code for Code 128 Scanning from Image
As is said above, RasterEdge VB.NET Code 128 barcode reader control can read Code 128 barcode from raster image file, like png, jpeg, gif, bmp or tiff. And here we take the Code 128 barcode recognition from TIFF file as an example. Using the VB.NET code below, you can detect and decode all Code 128 barcode from TIFF file and return decoded Code 128 barcode information as data string.
Public Shared FolderName As String = "c:/"
Private Sub button1_Click(sender As Object, e As EventArgs)
Dim fileName As String = FolderName & "SampleBarcode.tif"
Dim datas As String() = BarcodeScanner.Scan(fileName, BarcodeType.Code128)
For Each data As String In datas
Debug.WriteLine(data)
Next
End Sub
VB.NET Code to Decode Code 128 Image from PDF
Using this VB.NET demo code below, you can decode all Code 128 barcodes from one selected PDF page. Besides, if you want to accelerate the Code 128 barcode recognition rate, you can define a barcode scanning area with the application of X & Y location.
Public Shared FolderName As String = "c:/"
Private Sub button1_Click(sender As Object, e As EventArgs)
Dim fileName As String = FolderName & "Sample.pdf"
Dim reImage As REImage = DirectCast(REFile.OpenDocumentFile(fileName, New PDFDecoder()).GetPage(0).ToImage(), REImage)
Dim datas As String() = BarcodeScanner.Scan(reImage, BarcodeType.Code128)
For Each data As String In datas
Debug.WriteLine(data)
Next
End Sub
VB.NET Code to Read Code 128 Barcode from Word
The VB.NET programming example here is used to illustrate how to decode Code 128 barcode image from Word page (which can be accurately selected with
Word document page processor control). Remarkably, if you know the number of Code 128 barcodes in the target Word page, you are also able to set a maximum number of detected Code 128 barcode images.
Public Shared FolderName As String = "c:/"
Private Sub button1_Click(sender As Object, e As EventArgs)
Dim fileName As String = FolderName & "Sample.docx"
Dim reImage As REImage = DirectCast(REFile.OpenDocumentFile(fileName, New DOCXDecoder()).GetPage(0).ToImage(), REImage)
Dim datas As String() = BarcodeScanner.Scan(reImage, BarcodeType.Code128)
For Each data As String In datas
Debug.WriteLine(data)
Next
End Sub
