In order to avoid duplicate eventhandlers, I did like the following...
Document doc = Application.DocumentManager.MdiActiveDocument;
try { doc.BeginDocumentClose -= new DocumentBeginCloseEventHandler(MyEventHandler); }
catch { // Do nothing }
doc.BeginDocumentClose += new DocumentBeginCloseEventHandler(MyEventHandler);
The above worked greatly with AutoCAD 2007.
But yesterday I migrated my code into AutoCAD 2010 (with Object ARX 2010).
Unfortunately, it seems like AutoCAD 2010 catches before my code catches it.... (Though I am not sure if this is even make sense)
The evidence...
If I ignore this message, everything works great as it was meant to be...
I am just wondering if I could disable(?) this. Or if there is any other effective work around....
Well, I guess I could just have a global boolean value that checks the status of event attachment.
But would this be the only way?
