Hi Andrea,
I had the same problem some of years ago, not exactly with VIEWCTR, but it was something concerning to zooming.
As far as I know (deduced at that time, in a test and error way with many variables), not all Autocad's variables are managed by VLR-SYSVAR-REACTOR. I suppose VIEWCTR is among them... .
Regards.
Thank you Pepe..
Well,....you'r right ! some variables don't seem to work.
So I've to re-think my concept and found a workaround.
the goal of my idea is that I need to detect when user PAN or ZOOM the drawing with the wheel mouse.
So I've thinke to use DBMOD and reset a LISP variable,...then,...use the VIEWCTR,...but no succes..
(at this moment)
so If any of you got any idea who can help me with this..
It will be very appreciated.
thank you.
