This error can occur when you forget to add a method to your servant 
implementation class for one of the operations defined in IDL, or when you 
add a method with the wrong parameter types.

The error message from Visual C++ should include further information about 
which abstract virtual method was not overridden. Look for messages labelled 
"C4259" with the message "pure virtual function was not defined".
