Bob,
Thanks for your suggestion. I've only just found time to test it and
yes, it appears to work. I am having a problem with a System Error
occurring subsequently to this operation. It only seems to occur
following the 'pick point' feature but I'm not sure if it is a direct
result of it. Any ideas as to how I might pinpoint the cause of this?
There is an error code given, 34623, but I can't find any information
relating to it.
As for MapX, it's not an option for this particular project but I'll
keep it in mind for future reference.
Regards,
Keith
