Important Update
This page helps you to learn from code samples for programming in VB.NET. ByteScout Cloud API Server was created to assist barcode reader API in VB.NET. ByteScout Cloud API Server is API server that is ready to use and can be installed and deployed in less than 30 minutes on your own Windows server or server in a cloud. It can save data and files on your local server-based file storage or in Amazon AWS S3 storage. Data is processed solely on the API server and is powered by ByteScout engine, no cloud services or Internet connection is required for data processing..
Want to speed up the application development? Then this VB.NET, code samples for VB.NET, developers help to speed up the application development and writing a code when using ByteScout Cloud API Server. If you want to implement this functionality, you should copy and paste code below into your app using code editor. Then compile and run your application. VB.NET application implementation mostly involves various stages of the software development so even if the functionality works please check it with your data and the production environment.
