Effective and precise barcode reading is a critical component of many software development applications in a variety of sectors. Barcode technology makes data input easier, improves accuracy, and increases operational efficiency in a variety of industries, including retail, healthcare, logistics, and inventory management. Technology breakthroughs have made it easier and more convenient to integrate barcode reading capabilities into VB.NET applications.
This post will examine the topic of VB.NET barcode reader and discuss how IronBarcode, a well-liked .NET barcode library, may make the process go more smoothly. We will go through the basics of barcodes, the value of a barcode scanner in VB.NET applications, and how to use IronBarcode to build barcode scanning capabilities.
How to use the VB .NET For Barcode Reader Component
- Create a new project.
- Import the IronBarcode Library.
- Set the Image Path and Build an Instance of the BarcodeReader.
- Analyze data from barcodes.
- Print Barcode Information on the console.
Understanding Barcodes
In today's world, barcodes are found on a wide range of items, including identity cards, shipping labels, and product packaging. These machine-readable codes encode data in a way that .NET barcode reader components can readily read by using parallel lines, bars, and gaps of different lengths.
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.

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.
