Numeric Node ID Read from server|OPC UA Standard|Forum|OPC Foundation

How do I call a method which does have a numerical node identifier type (and not a string type)? 

A very lot of documentation is based on a String-Type like “ns=0;s=Demo.Dynamic.Scalar.Int32”, but I do need something like

“ns=0;i=2258”.

More Information:

Used Language: C++ based OPC UA Client/Server SDK + Pub/Sub Bundle v1.7.2

Node Address: “Root/Objects/Clear capture 1” or “Root/Objects/909”

NamespaceIndex: 0

Identifier Type: Numeric

Identifier: 2258

if it is string 

//nodesToRead[0].NodeId will have the value = “ns=0;s=Demo.Dynamic.Scalar.Int32”

//nodesToRead[0].NodeId will have the value =”ns=0;i=2258″

but when i add this/ replace with the numeric reading is failed 

nodesToRead[0].AttributeId = OpcUa_Attributes_Value;
OpcUa_NodeId_CopyTo(&nodes[0], &nodesToRead[0].NodeId);

result = m_pSession->read(serviceSettings, 0, OpcUa_TimestampsToReturn_Both, nodesToRead, values, diagnosticInfos);

I would be very happy about any help.
