You can't. LabVIEW's Call Library Node can only access global C style functions exported through the DLL export table. C++ functions are normally not exported at all but instead accessed through the method table of an object. Since the C++ binary interface is compiler dependant supporting such an interface would be very difficult for LabVIEW.

Your options are to use ActiveX instead, if your dll supports that, or write a standard C wrapper library that translates the C object methods into standard C function calls and export them from your DLL.
