Hi everyone,
I created the shape file by usinge the feature filed type: OFTInteger.
But when I open the file in Arcgis (ArcCatalog) the data type is: Double
(not integer).
Do you know how to fix this (I want it is Int) ?
Thanks and regards,

I am trying read features in a dgn file and convert to shape file.
Everything is ok before I adding the last while loop. After adding this

Do you know why ?
OGRRegisterAll();

The problem is: after the last while loop. I need to set SetSpatialFilter and
Feature again (The spatialfilter that used in the previous while loop), by
using below codes:
poLayer-SetSpatialFilter (poGeometry);
poLayer-SetNextByIndex (index2-1);
