How to tell if object is from query?

MarkSanchezSPEC — Tue, 21 Oct 2008 19:43:29 GMT

I am trying to figure out a solution that will allow us to maintain "sheets" in Map, whereby queried Map objects are combined with objects that are not contained in our Maps (ie borders, legends, etc) . The problem is that when a DWG sheet is closed all queried objects get saved to the DWG, then the next time it is open, and the query is re-run, we wind up with duplicate objects! Of course, this is expected as "the association between queried objects in the current and attached drawings is not maintained".

If there was a way to distinguish"queried" objects from objects that are part of the "sheet", then I could Delete them upon closing the DWG. Then when the sheet is re-opened, the user simply re-runs the query and no duplicate objects are created. So is there a way to programmattically distinguish"queried" objects from non-queried objects in a drawing?

Hi,

This function returns nil if a object does not come from a queried dwg:

(ade_qrygetdwgandhandle ename)

but should be used *before* you receive: "the association...bla bla.."
message.

Thank you very much - I will investigate this method - looks like there is an ARX equivalent too!
