I want to call dll function in openmodelica

Thanks for your quick reply sjoelund.se , I am trying to use Visual c++ file I am able to access simple function from vc++ file but  having trouble  in calling COM dll methods.

  I am new to openmodelica and trying to call external function using external keyword in modelica langugae.
I wonder if any one have done this before. I have tried to implement  example http://book.xogeny.com/behavior/functio … rpolation/
but failed to implement
