Hai,
I am trying to utilize digital signatures on my InfoPath forms. The
certificate was issued by Microsoft Certificate Authority. I attach the
digital signature to the document and no changes are allowed, but any user
can click on the digital signature -- the digital signature dialog box comes
us and they can remove the signature and make changes to the document. Can I
secure a document after it has been signed (maybe with the OnSign Event) so
that only the user that did the digital signature can pull up the document
and make changes?

Signature

Thank you,
xyz

Just add an OnBeforeChange handler on the group node that contain the
signature (if you use autogeneration it is the innermost signatureN node
where N is a number) and set ReturnValue to false in it. This will deny the
ability to remove a signature in Infopath.

Hope this helps

hello Alessandro,
I tried an example with ur information by adding
e.returnvalue=false onBeforechange handler on the groupnode that contain the
signature.But the signature is not added to the form even first time
also(Error : Violates the constraint).If i did not add this,then remove
option is not disabled.
Please explain in detail and send me a sample.
Thanks,
