generateusagedata messages

[fieldguy]

I am using generateusagedata in a batch file scanner with ReadDwgFile.  I start an autocad session and netload the dll.  Sometimes generateusagedata generates a message that says "A vertex was added to a 2D pline" and the handle of the object.

I want to know the name of the file that was being scanned at that time. I should be able to use an event handler??  The editor is not doing anything.  The messages are on the screen when I check the batch results.

1. How is it that that particular method is returning that message? generateusagedata should just generate data for the IsUsed property of the layerTableRecord object - according to the documentation, so presumably (and I could be wrong here - there should not be a message about polylines and vertexes?)
2. Perhaps post some code so that the issue can be replicated on someone else's PC? Otherwise it makes it harder to solve the problem.

There's something different about "GenerateUsageData".  I see the progress bar flash by in the bottom right corner.  I don't understand why I see anything in the editor.  

I was working on a dwg sample but I can't replicate it.  I found the file using debug.  The handles belong to 4 zero length plines.    When I strip everything else out of the file I don't get the messages anymore.  Unfortunately I can't post it here.  Below is all the code required to generate the messages.  I'll resurrect this post in the future if I get any more information.  Thx

                    LayerTable lt = (LayerTable)tr.GetObject(scandb.LayerTableId, OpenMode.ForRead);
                    lt.GenerateUsageData();
                    tr.Commit();
                }//
            }// foreach
            ed.WriteMessage(msg);
        }// scanfiles - acad command

I have no idea.

I could not replicate that problem.

Output the name of each file you process to the command line, and turn on console logging.
