I'm a developer using .net framework with c# and I wrote numerous programmes for AutoCAD 2010 and they are working great. Also I'm trying to use those programmes with AutoCAD 2012, but they aren't working the way I was expecting. Because my programmes are using the event DocumentToBeActivated (Application.DocumentManager.DocumentToBeDeactivated).
In AutoCAD 2010 this event was working whenever the document was about to be activated, but in AutoCAD 2012 it only appears to be work when switching between opened documents within the application.
So, is this a bug or isn't it the same way to use like in AutoCAD 2010 or something else...
And I also downloaded and installed the Service Pack 1 for AutoCAD 2012, and that even resolved the problem.
