Hi,
Thanks for your response and the code. Unfortunately, it doesn't work with
the PDF that I created using Adobe LiveCycle ES 2 (on Windows Vista). If
viewed using Acrobat, the field is empty or unchanged. But with FormTest,
the text field is updated. I tried your form (f941.pdf) and the fields are
also updated. Could this be a font issue? I noticed that the font used in
the PDF file is LucidaSans (Type: TrueType, Encoding:Ansi, Actual Font:
Adobe Sans MM, Actual Font Type: Type 1). Should this be "Arial" or similar
to the value in doc.CreateFont ("Arial")?
Thanks,
