IOpcSignatureRelationshipReference::GetTransformMethod method
Gets the canonicalization method to use on the relationship markup of the selected relationships when they are signed.
Syntax
HRESULT GetTransformMethod( [out, retval] OPC_CANONICALIZATION_METHOD *transformMethod );
Parameters
- transformMethod [out, retval]
-
The canonicalization method to use on the relationship markup of the selected relationships when they are signed.
Return value
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
| Return code | Description |
