[ms4w-users] OGR and DGN: doesn't work

[Berényi Attila]

Thank you both for the fast response.
The key was the version of the dgn files. With v7 files it looks like 
the mapserver works correct, although the whole map area is white and i 
don't see my map in the map area...maybe it's because of the false 
configuration of the .map file?
Here it is:

Any suggestion?

Thanks in advance,
