Hi Don,
Thank you for the example.
The columns that I listed are just the standard columns that OGR will give you if you open a DXF file (see gdal.org/ogr/drv_dxf.html)
Unfortunately, I have not had any success connecting to my dxf files, but I want to throw an idea out there.
I am using WpfDesktopEdition version 6.0.0.0. I have noticed that in \System32\MapSuiteFdoExtension the FDOExtension references FDO.dll version 3.5 and gdal16.dll version 1.6.
I then looked on the FDO website and found that version 3.5 does indeed include gdal16.dll (see fdo.osgeo.org/content/downloads, fdo.osgeo.org/content/fdo-350-downloads)
Finally, I looked through the gdal website and found that DXF support was not introduced into OGR until gdal version 1.7, although, on an aside, they withdrew this version because of a problem with one of the drivers - so maybe don't use that one :) (see trac.osgeo.org/gdal/wiki/DownloadSource, trac.osgeo.org/gdal/wiki/Release/1.7.0-News)
I am not sure if I should get an updated version of MapSuite or something else, but as far as I can tell, there wiil be no support for DXF in my environment because the version of FDO, GDAL and OGR that is used doesn't support it.
There are a couple of other releases of FDO that have happened since 3.5; maybe MapSuite could be built against a later version? This would provide more formats and bug fixes (and, obviously, a logistical nightmare for you when the API changes)
