How to use the VB .NET For Barcode Reader Component

Barcodes have several uses, such as

• Inventory management includes keeping tabs on stock levels, overseeing resources, and optimizing supply chain processes.
• Retail: Managing pricing, monitoring sales, and expediting checkout procedures.
• Healthcare: Accurately and efficiently identifying individuals, prescription drugs, and medical equipment.
• Document management includes organizing records, indexing materials, and making retrieval easier.
• There are several types of barcodes, such as QR codes, Code 39, Code 128, EAN (European Article Number), and UPC (Universal Product Code). Every format has unique qualities and works well with various applications.

Key features of IronBarcode include

• Support for a Variety of Barcode Formats: IronBarcode is compatible with several industry standards and supports many barcode formats, such as UPC-A, UPC-E, EAN-8, EAN-13, Code 39, Code 128, QR codes, and more.
• High Accuracy: IronBarcode uses cutting-edge algorithms to guarantee dependable and precise barcode detection, especially in difficult situations when barcodes are damaged or of poor quality.
• Simple Integration: IronBarcode easily integrates into VB.NET projects thanks to its clear API and thorough documentation, allowing for the quick creation and implementation of barcode reading capabilities.
• Cross-Platform Compatibility: IronBarcode may be used on a variety of platforms and contexts since it is compatible with both the .NET Framework and .NET Core.
• Options for Customization: To meet their unique needs, developers can alter the type, orientation, size, and resolution of barcodes as well as other features of barcode scanners.
• Seamless .NET Integration: IronBarcode supports 32-bit and 64-bit architectures and is compatible with .NET Framework and .NET Core implementations.

Creating a New Project in Visual Studio

Select "New Project" from the file menu while Visual Studio is open, then "Console App," "Windows Forms," or "WPF Application." We are selecting the Visual Basic Console App in this article. There are a wide range of applications for barcodes. Programs like Webform/MVC/MVC Core are another option.

Enter the project name and choose the file path in the corresponding text box. Select "Next" by clicking.

Next, make the required selection. We are choosing a .NET framework for our lesson .NET 6.0, after which you should select "Create" to start the project.

If you select a console application, the project will now create the necessary framework and launch the program.cs file, allowing you to input code and execute/build the application.

Installing the IronBarcode Library

Downloading the necessary package is necessary to use the IronBarcode library in the solution. Use the following command in the Package Manager console to do this:

Install-Package BarCode

Similar to the picture below:

Other options include utilizing the NuGet Package Manager to look for and download the "Barcode" package, which will show all the search results. After that, you may decide which of their packages to download and install into the software.

Barcode Reading Using IronBarcode

Let's now examine how to use IronBarcode in VB.NET to scan barcode images:

Imports IronBarCode

Module Program
    Sub Main()
        ' Define the path to the image containing the barcode
        Dim imagePath As String = "Demo.png"

        ' Read barcodes from the image file
        Dim result = BarcodeReader.Read(imagePath)

        ' Check if any barcode was detected
        If result IsNot Nothing AndAlso result.Count > 0 Then
            ' Iterate over detected barcodes
            For Each barcode In result
                ' Print barcode type and value
                Console.WriteLine($"Barcode Type: {barcode.BarcodeType}")
                Console.WriteLine($"Barcode Value: {barcode.Value}")
            Next
        Else
            ' Inform the user if no barcode was detected
            Console.WriteLine("No barcode found in the image.")
        End If
    End Sub
End Module

Imports IronBarCode

Module Program
    Sub Main()
        ' Define the path to the image containing the barcode
        Dim imagePath As String = "Demo.png"

        ' Read barcodes from the image file
        Dim result = BarcodeReader.Read(imagePath)

        ' Check if any barcode was detected
        If result IsNot Nothing AndAlso result.Count > 0 Then
            ' Iterate over detected barcodes
            For Each barcode In result
                ' Print barcode type and value
                Console.WriteLine($"Barcode Type: {barcode.BarcodeType}")
                Console.WriteLine($"Barcode Value: {barcode.Value}")
            Next
        Else
            ' Inform the user if no barcode was detected
            Console.WriteLine("No barcode found in the image.")
        End If
    End Sub
End Module

To utilize IronBarcode functionality, start by importing the IronBarcode namespace. Specify the location of the picture file with the barcode images you wish to read. The path to your barcode image files should be substituted for "Demo.png". Create an instance of the BarcodeReader object, which offers ways to read barcodes from various sources.

Using the BarcodeReader's Read method scans barcode data from the designated picture file. Verify whether any barcodes can be found in the picture. If barcodes are located, print the type and value of each iteration to the console. If none are found, print a message saying that the barcode was not detected. We are going to read the below barcode image with the help of the above code.

Below is the image generated from the above barcode image.
