Please log in for more thread options Hi Willem,
Ah, stupid me, I searched for a lot of stuff in the help, but looking for
av.Run() never occured to me.
Well, now everything runs just fine except calling the script using DDE. I
am not fond of DDE myself either, I just dont see any other way to trigger
the script from outside.
I'll try to find a way to move the script from the project into the ArcView
installation, maybe DDE will work then - I still need to figure out how to
do this, probably got to create an 'extension' for this I think?
Anyway, thanks a lot for the fast help!
