IOpcRelationshipSelector::GetSelectionCriterion method

Gets a string that is used to select relationships to be referenced for signing.

Syntax

HRESULT GetSelectionCriterion(
  [out, retval] LPCWSTR *selectionCriterion
);

Parameters

selectionCriterion [out, retval]

A string used to select relationships to be referenced for signing.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Remarks

This method allocates memory used by the string returned in selectionCriterion. If the method succeeds, call the CoTaskMemFree function to free the memory.

Use the IOpcRelationshipSelector interface methods to select relationships for signing. A relationship is selected if its type or identifier matches the string that is retrieved by calling the GetSelectionCriterion method. This string is either a relationship type or a relationship identifier. Call the GetSelectorType method to get an OPC_RELATIONSHIP_SELECTOR value to determine whether the string is a relationship type or an identifier. To access these relationship properties, call the IOpcRelationship::GetRelationshipType and IOpcRelationship::GetId methods.
