title: iTextSharp Header Footer help
body: <p>I am using iTextSharp to generate pdf in my .net application.
  Now I want to add Header and Footer in my pdf document.
  I got code from a site something like given below but it doesn't work.
  [
   //we Add a Header that will show up on PAGE 1
   HeaderFooter header = new HeaderFooter(new Phrase("This is a header"), false);
   document.Header = header;
  ]
  I create document object like:-
  Dim document As text.Document = New text.Document(iTextSharp.text.PageSize.A4, 25, 25, 25, 25)
  But it doesn't have property of Header as mention in the above code.
  Can anyone suggest me how to do it.</p>
