Greetings to all.
I apologise in advance for my ignorance. I am trying to learn, using
iTextSharp, how to take an existing PDF and add a bit of text to it in a VB.NET
environment. I am waiting for my copy of the book iText In Action to arrive,
but wanted to try getting a head start... It would appear I am missing
something very important.
Here is my VB code-behind page:

EventArgs)
Dim fileName As String = "pdfDocument" & DateTime.Now.Ticks & ".pdf"
Dim text As String = TextBox1.Text
Dim document As New Document()
Dim bf_times As BaseFont = BaseFont.CreateFont(BaseFont.TIMES_ROMAN,
"Cp1252", False)
Dim sourcepdf As String =
System.AppDomain.CurrentDomain.BaseDirectory() &
"SourcePDFs\CRM1008-01-MoreRefLtr.pdf"
Dim reader As PdfReader = New PdfReader(sourcepdf)
Dim stamp As PdfStamper = New PdfStamper(reader, Response.OutputStream)
Response.Clear()
Dim content As PdfContentByte = stamp.GetUnderContent(1)
Dim txt As PdfContentByte = stamp.GetOverContent(1)
txt.BeginText()
txt.SetTextMatrix(250, 250)
txt.SetFontAndSize(bf_times, 14)
txt.ShowText(text)
txt.EndText()
content.Add(txt)
stamp.Close()
Response.ContentType = "application/pdf"
Response.AddHeader("content-disposition", "attachment filename=" +
fileName)
Response.Flush()
Response.End()
End Sub
End Class
____________________________________
My content page simply contains a single textbox and a button to create and
download the PDF to the user.
My application will accept the text into the box, and clicking the button
successfully creates a PDF. But when the downloaded PDF is opened, Adobe
claims that the file is damaged and cannot be opened.
Have I missed something in how to add the text or properly code the PDF output?
Thank you in advance for any assistance you can offer.
