Autocad Map file still in use after import

[andrew_demerchant]

I'm able to import some shp files without any trouble...but for some reason, autocad is keeping the files open after the import, and I want to delete them. I've tried disposing and/or setting vars to nothing, but can't seem to get them released without closing Autocad completely. I've imported using Autodesk.Gis.Map.HostMapApplicationServices.Application.Importer....Anyone have any tips?

I did a few Map importing/exporting development and had never needed to erase shape files after they being imported into drawing. Yes, I can confirm that Autodesk.Gis.Map.ImportExport.Importer does not release the shape file after it is imported into drawing, thus the shape file (and some of its comopanion files *.dbf, *.shx...).

Although Import is an IDisposable object, our custom code cannot really dispose it, even Importer.Dispose() is clled explicitly, because Importer is exposed via static MapApplication as its property. We, as outsider, do not know how this property is implemented, but I'd guess that this property points an singleton of Importer instance, so that as long as the MapApplication alive, the Importer alway lives.Therefore only closing AutoCAD kills the Importer, thus the shape file is released then.

Technically, importing shape file is differently from connecting AutoCAD to shape file via FDO, there is no reason for MapApplication/Importer to hold the shape file after it being imported. Autodesk's Map team should take this as a bug to be fixed.

That's definitely what I've found here too. Would be a good bug to get fixed...until then, I guess I'm going to have to come up with a workaround for my project. Thanks
