Introduction
In today's 'big data era', more and more organizations areusing an enterprise content management (ECM) or record management system (RMS)to help maintain and manage the documents. Digitizing documents and storingthem in a central database has become an important part of many organization's documentmanagement workflow. For this purpose, we will illustrate creating anapplication to capture documents as images from scanners and webcams. We'llalso cover how to save them in SQL Server in C#.
We will be using Dynamic .NET TWAIN to expedite development and deployment of such an application. Dynamic .NET TWAIN is a document scanning SDK based on the.NET Framework 2.0/4.0. The SDK enables users to capture images from TWAINscanners and UVC/WIA webcams. It also allows simple edits or processing.Finally, it enables saving of images to your local/server disk, FTP site ordatabase from your WinForm application.
