Last month, Microsoft released .NET Core 3.0 that allows developers to port Windows Forms and Windows Presentation Foundation (WPF) projects to the .NET Core projects. However, the feature is still Windows-only, which may disappoint someone who wants to create cross-platform ...

Mono is an open source implementation of Microsoft’s .NET Framework. It aims to help C# developers create cross-platform .NET applications. Although .NET Core is born for multiple platforms (Windows, Linux, and macOS), it is so far not a substitution of .NET framework. If you ...

This article shows how to use Dynamsoft C++ barcode reader SDK to create a Window runtime component, as well as how to use the WinRT component and JavaScript to build a UWP app on Windows 10.

This tutorial aims to help .NET developers use Dynamic .NET TWAIN in Unity projects.

ZXing is probably the most popular open source barcode SDK in the world. The library is written in Java and now has been ported to C++, .NET, Python, Objective-C, PHP and some other programming languages. Because ZXing is free, many developers would like to build barcode scan ...

When you release a JavaScript library, such as jQuery, online, you may need to collect some status information for analytics. If you deploy your website on IIS, you can use HTTP Module to capture HTTP requests of HTML, JS and CSS files. My goal is to make a statistic of how m ...

OpenCV is written in C++.  If you install OpenCV library on Windows, you will see OpenCV officially provides wrappers for Python and Java but not for C#. Fortunately, there are many .NET open source projects for wrapping OpenCV C++ APIs, and thus we don’t need to write a wrap ...

.NET Core empowers C# developers to build DotNet applications for Windows, Linux, and macOS using one codebase. In this article, I want to share how to create a cross-platform .NET Core barcode app with Dynamsoft Barcode Reader SDK.

C# is the preferred programming language for developing Windows applications. However, Microsoft only provides .NET camera APIs for UWP applications. If you plan to write a classic Windows desktop application using a webcam, it will be complicated to create a C/C++ wrapper fo ...

Previously I shared how to use Touchless, which wraps the win32 APIs of DirectShow, to control webcam in C#. In this article, let’s take a further step to see how to use the more complicated DirectShow.NET APIs to capture the video stream and read barcode from preview frames ...

When building a .NET application to read barcodes on Windows via camera, you need two types of SDKs - one for webcam, and the other for barcodes. In this post, I want to share how to use .Net webcam and barcode SDKs to create a simple WinForm barcode reader application in C#.

If you have a USB camera, how can you build a simple C# camera application on Windows 10? There are three options:  WIA (Windows Imaging Acquisition), DirectShow and MediaCapture. After trying some sample code that downloaded from CodeProject and GitHub, I got the conclusion: ...

On mobile platforms, HTML5 is not only supported by web browsers, such as Safari, Firefox, Opera, Chrome, but also web view UI component that used for building native apps. The benefit is apparent that any developer who is familiar with web programming could easily create exc ...

Probably many Windows developers have upgraded operating systems to Windows 10. On Windows 10, Microsoft suggests developers create Universal Windows Apps (UWP) for a variety of devices, including PC, tablet, mobile phone, Hololens and so on. For development, I wonder whether ...

Have you implemented any barcode reader software in Swift on Mac OS X? Since Dynamsoft released the 1D/2D barcode SDK for Mac, I was wondering how I can bridge the C dylib with Swift. Why Swift, not Objective-C? Because Apple is encouraging developers to migrate to the new pr ...

Last week, Dynamsoft released Barcode Reader (DBR) SDK v2.0, which is available for Windows and Mac. The Windows installer contains Barcode libraries for ActiveX, C/C++, and .NET. If you are a Java developer, you have to use JNI to link native C/C++ libraries. In this tutoria ...

Dynamsoft OCR SDK is totally implemented in C++, which means it is easy to be wrapped in high-level programming languages, such as C#, Java, Python and so on. As a proprietary development SDK, so far, only .NET OCR library is available for commercial use. Because some of deve ...

Xamarin platform helps .Net developers to easily build applications for Android, iOS, Mac and Windows in C#. Let’s take a look at how to create our first Android demo with Xamarin in Visual Studio 2013.

If you have a TWAIN-compliant scanner, you can easily control it with Dynamic Web TWAIN or Dynamic .NET TWAIN. Both SDKs can help you create some excellent applications for document scanning and management on PCs. However, have you ever complained that it’s so inconvenient to ...

Dynamic .NET TWAIN is one of the excellent TWAIN-compliant SDKs for document scanning and image capture. In this tutorial, I would like to share how to create a bridge to convert .NET TWAIN C# methods to Java methods in order to help Java developers easily implement Java TWAI ...

Last week, I shared how to transmit an image between a WebSocket server and a Web client. Based on that, we can make a little bit of improvement. Today, I would like to share how to generate barcode on .Net server side and display it on web browser.

HTML5 WebSocket facilitates the communication between web browsers and local/remote servers. If you want to learn a simple websocket example, creating a WebSocket Server in C## and a Web client in JavaScript, you can refer to SuperWebSocket, which is a .NET implementation of ...

If you ever developed some iOS or Android apps, you should know that for localization, the strings should be stored in some resource files and dynamically loaded in apps. What about Windows applications?
