Hello,

Using pre-release 7.0.153 (.Net )
1) I have trouble accessing the value of the property signatureName and fieldname of TElPdfSignature and TElEmptysignature class.
Using my code or the tinyprocessor sample it always return some strange characters (someting like "bÿ")

2) And... out of curiosity, what do the prefix TEl and El stand for ?

I can upload a sample pdf if you want me to...
thank you.

Mmm, PDFBlackbox does not contain such class as TElEmptysignature (I assume, you are talking about TElPDFSignatureInfo one?). It would be great if you attach a document that exposes the issue either here or to the Helpdesk.

The prefix has a historical origin and is preserved for the sake of backward compatibility of the existing code. "T" is a Delphi-style prefix (stands for "Type") and "El" are just two first letters of the name of our company.

This values wasn't properly decoded.
Please, use a following code to decode strings for now:
Code
string sigName = SBPDFCore.Unit.DecodeTextString(SBUtils.Unit.BytesOfString(Signature.SignatureName));
and
string fieldName = SBPDFCore.Unit.DecodeTextString(SBUtils.Unit.BytesOfString(Document.get_EmptySignatureFields(0).FieldName));
