>Sorry, it has been about 3 years since I wrote that code. i forget that is my function

Thanks, is this still working? Because, I have an error on the 3rd line:

    Private Function GetPDFFormFields(ByVal pdfform As String) As String
        Dim pdfformfields As String
        Dim PdfReader As iTextSharp.text.pdf.PdfReader = New iTextSharp.text.pdf.PdfReader(pdfform)
        Dim fieldlist As New ArrayList(PdfReader.AcroFields.Fields.Keys)

Unable to cast object of type 'KeyCollection[System.String,iTextSharp.text.pdf.AcroFields+Item]' to type 'System.Collections.ICollection'.
