Signatures Collection
Contains a collection of Signature objects for each signature in the Microsoft Office InfoPath 2003 form or SignedDataBlock object.
Remarks
The Signatures collection implements properties and a method that can be used to access a form's associated Signature objects and to create a signature. It is accessible through the SignedDataBlock object.
Note This object model member is not supported when the Disable Service Pack features option on the Advanced tab of the Options dialog box in InfoPath is selected or when Microsoft Office 2003 Service Pack 1 or later is not installed. Any form that implements this object model member in its code will generate an error message if it is opened in InfoPath when service pack features are disabled or unavailable.
Using the Signatures collection
When using the Create method, the signature is not written until the Sign method is called on the Signature object. These methods can be called only from the OnSign event handler.
