[gdal-dev] Bug in SetField
my code field - fieldname is of string type and 0th field poFeature-SetField(fieldname,value); poFeature-GetFieldAsString(0); returns v instead of value; I dont know is it bug or my problem but I opened the shapefile in OpenJUMP and QGIS both shows field names as only v instead of value I am working with shapefiles -- Thanks Regards Rashad ___ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev

SetField() will automatically truncate the value in such a case.
