Create a Polygon-Featureclass with standard columns SHAPE_Length and SHAPE_Area

[TOPOGRAPHICS]

Hello,

I wonder, how I can create a Polygon-Featureclass with the two standard-columns SHAPE_Length and SHAPE_Area. Must I create and fill the two columns by my own, programmatical?

I'm using the FileGeodatabase API 1.5.2 in the GDAL-Environment.

Thanks a lot for support.

At the moment, only the geo column is created, but not the other two columns SHAPE_length ans SHAPE_area.
