Oscar,
please do not spawn multiple requests of same type.
In the other thread earlier today "stamp in datawindow" I explained how to get an electronic signature in PB, as you asked.
Now you are referring to "stamp in pfc", I guess it is a typo and you mean "in a PDF"?
I think you need first of all to get some knowledge of the terms you are using: digital signature is not electronic signature, which are not stamps.
A stamp is usually an hash of a given object, electronic signature is a graphical digital handwritten signature, digital signature is a mathematical form to guarantee authenticity of a document.
- In order to implement electorinc signature in PB you just need to use an Ink Picture control (on a form, VO or datawindow).
- Digital signature is way more complex, it is based on X509 certificates and you would need 1) 3rd party commercial tools to sign a document or 2) develop your own java/.net wrap to existing SDKs (bouncycastle being the leading project to this extent).
HTH,
Marco
