Hi Claude, thanks for the reply.

>Check out the Foxwiki for more info on WSDL:...

At what stage is the WSDL file generated? Building the .dll has created the vbr and tlb files, but I can't find the WSDL anywhere.

>FUNCTION Error(nError, cMethod, nLine)
> COMreturnerror(cMethod+' err#='+str(nError,5)+'
>line='+str(nline,6)+' '+message(),_VFP.ServerName)
> && this line is never executed

If I add the error function to the class, will it be called automatically when an error occurs, or do I need an explicit ON ERROR DO ... call?

Many thanks,
Alan
