XdSignatureRelation Enumeration (Microsoft.Office.Interop.InfoPath.SemiTrust)

The XdSignatureRelation enumeration is used to determine how digital signatures can be added to a SignedDataBlockObject object.

Namespace: Microsoft.Office.Interop.InfoPath.SemiTrust
Assembly: Microsoft.Office.Interop.InfoPath.SemiTrust (in microsoft.office.interop.infopath.semitrust.dll)

'Declaration
Public Enumeration XdSignatureRelation
'Usage
Dim instance As XdSignatureRelation

 Member nameDescription
xdSignatureRelationCoSignSpecifies that signatures are independent of each other in SignedDataBlock
xdSignatureRelationCounterSignSpecifies that each signature signs the preceding signature in the SignedDataBlock
xdSignatureRelationSingleSpecifies that only one signature can exist in the SignedDataBlock

These enumerated values are returned by the SignatureRelation property.

public void DisplaySDBProperties()
{
 SignedDataBlock sdb = thisXDocument.SignedDataBlocks[0];
 string sigRelation = "UNKNOWN";
 switch(sdb.SignatureRelation)
  {
   case XdSignatureRelation.xdSignatureRelationSingle :
    sigRelation = "SINGLE";
    break;
   case XdSignatureRelation.xdSignatureRelationCoSign :
    sigRelation = "COSIGN";
    break;
   case XdSignatureRelation.xdSignatureRelationCounterSign :
    sigRelation = "COUNTERSIGN";
    break;
   default:
    break;
  }
 thisXDocument.UI.Alert("Signatures relation: " + sigRelation );
