Here's a tip learnt the hard way.
(see piccy)
Modeless form,
I wanted to be able to manually edit the Offset Distance and have the Area update automagically.
..ditto in reverse
The Area TextBox wouldn't update ...
I tried a couple of simple samples to send to Owen with a report .. and it worked !!
So, long story short ..
I was doing some calc's behind the scenes to calculate the Area using (vl-cmdf-xx stuff ( these are NOT simple rectangular shapes )
It finally clicked that I needed to set the EventInvoke property from 0 to 1 To allow the 'Command' Lisp Function to be used ..
