Signing PDF

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have a system that generates PDF reports that I need to sign and encrypt. What I still miss is showing a signature field on the report. I use nIndex=.oPdf.NewFormField(cSignField,6) and refers to the same field name in .oPdf.SignFile(), but it dosn't show up in Acrobat. I need a sample showing how to do this.

	I don't get this right, so I try to explain further. I have a sequence that goes like this: nIndex=.oPdf.NewFormField(cSignField,6) .oPdf.SetFormFieldBounds(nIndex,this.GetKolPos(1),this.GetRadPos(58),200,48) .oPDF.SaveToFile(tempfile) nRes=.oPDF.SignFile(tempfile, '',cSignField,.RapportFil,('Myfile.pfx'),'pass','','','') After saving to the tempfile, I have a unsigned field which I can manually sign in Acrobat. But after SignFile() my reportfile have no signaturefield. There is no error and I am sure it is written by SignFile().

	I have figured out that the PDF file I have generated using Quick PDF looks fine and can be encoded, but not signed using SignFile()! I can sign it using Acrobat. The file is initially created using MS-Word and printed using a PDF printer to a template. Then it is filled with content using QuickPDF. After signing it using QuickPDF.SignFile() and reading it in Acrobat, the sign field is obviously removed. But I can sign the template using SignFile(), so what can be wrong here?

	This knowledge base article should help you: http://help.quickpdflibrary.com/questions/101/i-digitally-signed-a-pdf-but-i-cant-see-the-signature-in-the-document Quick PDF Library adds document level digital signatures. It does not let you digitally sign form field signatures.
