Once that is done, we need to add a reference to it by clicking Project->Add Reference->iTextSharp.dll.
Mine looks like Figure 1 :īefore we can jump in and code, you need to make sure that you have downloaded the iTextSharp libraries. All we need is a progress bar and a button. Our project doesn’t have much of a design. Sound easy enough, yes, with the help of the iTextSharp library you will see how simple it is. Our project’s aim is to read from a PDF file, change some of the contents and then add a watermark to the PDF document’s pages. I cannot do everything for you, you need to have some input as well. I would suggest that you go through the documentation properly before proceeding with our project. As you can see, iTextSharp is mostly for C# and Java hence this Visual Basic.NET article.

VB.NET PDF SEARCH HOW TO
With this article I will demonstrate how to use iTextSharp with VB.NET to manipulate PDF files. From the moment I started using it, I fell in love with it. VB.NET unfortunately doesn’t have a built in PDF file reader object, so I had to make use of a third party’s product called iTextSharp. Recently, I had to make a VB.NET program that reads PDF file contents and replace it with customized text.
