Important Update
Easy to understand coding instructions are written to assist you to try-out the features without the requirement to write your own code. ByteScout Cloud API Server was created to assist PDF to XML API in VB.NET. ByteScout Cloud API Server is the ready to deploy Web API Server that can be deployed in less than thirty minutes into your own in-house Windows server (no Internet connnection is required to process data!) or into private cloud server. Can store data on in-house local server based storage or in Amazon AWS S3 bucket. Processing data solely on the server using built-in ByteScout powered engine, no cloud services are used to process your data!.
The below SDK samples describe how to quickly make your application do PDF to XML API in VB.NET with the help of ByteScout Cloud API Server. Just copy and paste this VB.NET sample code to your VB.NET application’s code editor, add a reference to ByteScout Cloud API Server (if you haven’t added yet) and you are ready to go! Further improvement of the code will make it more robust.
