1. The first error: replace (2) with New Integer(){2}.
 2. Be sure to download the latest iTextSharp. I just downloaded the dll and add the reference, and I do not see these issues.
 BTW, are you using VB 2003, VB 2005, VB 2008 or VB 2010? I tested in both VB 2008 and VB 2010.

I just tried version 0.01, 0.02, 0.03, and 0.04. They all did not work. I got same errors.
But when I tried v3.0.0, it worked. Apparently those functions are not available until version 3.0.0.
Please download version 3.0.0 and try it. Hopefully it will work for you.
