   What is the @51 doing there   
      
   DLL calls can be by Name or by Number   
   - you are using both   
      
   It would be a good idea to check that the DLL uses the StdCall   
   convention.   
      
   Also: ( ByVal countryname As String) As Long   
      
   It is unlikely that a C DLL would want it ByRef

   Probably the same code as that in the DLL is also in the .LIB file
