During compile I am getting error C3861: "UNREFERENCED_PARAMETER" : identifier not found. This is in a managed c++ project for a custom entity wrapper library. Any thoughts?</P><P>&nbsp;</P><P>Mike</P> Fri, 27 Jan 2017 16:17:33 GMT https://forums.autodesk.com/t5/objectarx-forum/unreferenced-parameter-is-undefined/m-p/6836058#M8845 Anonymous 2017-01-27T16:17:33Z https://forums.autodesk.com/t5/objectarx-forum/unreferenced-parameter-is-undefined/m-p/6837158#M8846 <P>In winnt.h this macros is defined.
