[Anonymous]

I have a problem. I use AutoCAD 2010. I want  to know the use click save or discard button when close the document. I know the "Saved" Property of  AcadDocument can tell me the result. However, I could not use the AcadDocument Class. Because there is another plug-in, when i use the com class just like AcadDocument , it will tell some error.so i only can use .net Class just like Document. Is there any Proprty to get it ?
