Create WPF Browser Application to Scan a Document from Scanner(ADF and Flatbed) Using WIA

In this article I am going to explain how to create the WPF browser application to scan the documents from scanner with ADF and Flatbed facilities using the browser.

Let's Start with step by step instructions to create the WPF browser application for scanning the documents.

 

Step 1: First open the visual studio and select the project type WPF Browser based Application.

 

Check in this Image how to create WPF browser application,

 

Step 2: In the second step design your page as you want to view in browser accordingly.   

 

Step 3:  Now you have to add the Interop.WIA.dll and itextsharp.dll in your project reference.

 

Step 4:  Now you have to add System.Drawing and System.Web Assemblies. 

 

Step 5:  Now Generate the click event to start the scanning. 

Step 6:  Here I have given all the code, just go through that and you can change the code according to your requirement or just copy and paste into your cs page.
