Hi Viv.
Many thanks for detailed explanation
I'll spend a bit of time seeing if I can implement
regards,
Gerard

In the project properties:

>Application/Assembly Information : Check 'Make assembly COM visible'
>Build : Check 'Register for COM interop'
>
>In VFP :

x = CREATEOBJECT("GerardsCom.GerardsClass")
>? x.GetMeaningOfLife()

If you don't want/need intellisense then you can simply use:

public class GerardsClass
>    {
>        public int GetMeaningOfLife()
>        {
>            return 42;
>        }
>    }
