I have been trying to develop an InfoPath solution where I retrieve a users
certificate from Active Directory and manually sign the form after asking for
username and password. I found a good article dealing with this in InfoPath
2003 using the old object model at
http://msdn2.microsoft.com/en-us/library/bb608325(office.11).aspx but I want
to use the new 2007 OM. I have been unable to find any documentation on how
to override the wizard. I see no Add() method or Items properties in the
SignedDataBlock class or Signature class. Has anyone looked into this or
tried it in 2007 that can point me to the right direction. Much appreciated.
