An event object that is used during the OnSign event.
Version Information Version Added: InfoPath 2003
Remarks
Use the SignedDataBlock property of the SignEventObject object to determine which signed data block is triggering the OnSign event. The OnSign event is raised for a fully trusted form template only.
Example
In the following example, the SignEvent object is used to add a signature and timestamp to a SignedDataBlock object:
// Countersign the signature with a trusted timestamp.
// Get the XML node storing the signature block.
IXMLDOMNode oNodeSig = signature.SignatureBlockXmlNode;
IXMLDOMNode oNodeSigValue = oNodeSig.selectSingleNode(".//*[local-name(.)=’signatureValue’]");
// Get time stamp from timestamp service (fictitious).
MyTrustedTimeStampingService s = new MyTrustedTimeStampingService();
string strVerifiedTimeStamp = s.AddTimeStamp(oNodeSigValue.text);
//Add the value returned from the timestamping service to the
//unsigned part of the signature block.
IXMLDOMNode oNodeObj = oNodeSig.selectSingleNode(".//*[local-name(.)=’Object’]");
IXMLDOMNode oNode = oNodeObj.cloneNode(false);
oNode.text = strVerifiedTimeStamp;
oNodeObj.parentNode.appendChild(oNode);
e.ReturnStatus = true;
