Distinguish the two identical documents in the different Autocad instances

[Anonymous]

Hello,

How can I distinguish the two identical documents that are open in different instances of the Autocad application? I can't find properties in the Autodesk.AutoCAD.Interop.AcadDocument class that can distinguish these documents.

I have a task to determine other open instances of the document, except for the active one (the documents are open in other Autocad application instances also can be Active).

Thank you!

The com interop api doesn't have file system properties. Use the vb FileSystem to compare file attributes.
