Advice on FDF and PDF files
Posted on 2006-11-21
I need some urgent advice on FDF and PDF files..
I have created VB.NET app with MS SQL back end.
I also have PDF documents that need to be populated with data from app that I have developed.
Looking through EE, I came across the following code:
Dim sb As New System.Text.StringBuilder
Dim file As New System.IO.StreamWriter("POneEventQuote2007.fdf")
'***Create a replica of the FDF file's contents by creating a string containing all the
'***information in the FDF file.
'***vbCr's replace Hex value x0D found when viewing the original FDF File with a hex
sb.Append("%FDF-1.2" & vbCr & "%âãÏÓ" & vbCrLf)
sb.Append("1 0 obj<</FDF<</F(POneEventQuote2007.pdf)/ID[<e099e1fa40427741839c37afe39f0f67><d9326d3e5b7f764b8c0bb9fa30e73040>]/Fields[<</T(A0)/V(N/A)>><</T(R9)/V(0)>><</T(Z5)/V(REPLACE_NAME\rREPLACE_ADDRESS)>>]>>>>" & vbCr & "endobj" & vbCr & "trailer" & vbCrLf)
sb.Append("<</Root 1 0 R>>" & vbCrLf)
sb.Append("%%EOF" & vbCrLf)
'***Replace the default values with the "real" values
sb.Replace("REPLACE_NAME", "John Smith")
sb.Replace("REPLACE_ADDRESS", "London, UK")
Catch ex As Exception
'***Code to display your error goes here.
This allows me to create an FDF file, which when accessed will open the pdf file with the fields populated.
My questions are:
1. Is there a quicker to achieve the above, without going for 3rd party apps? (what if the pdf form has alot of text fields to populate?)
2. What i also want to do is to save the PDF with the data populated from the FDF without having to open the PDF and saving it in Reader. Can this be done in VB.NET?
Looking forward to your suggestions,
