How can I recalculate the spatial index for a featureclass in SQL Server programatically?

I already use the interfaces IIndexEdit and IGeometryDefEdit to recalculate the index by cloning the old index, following the example "RebuildSpatialIndex" in the developer help.

But I have to recalculate the extent because of performance issues. I can do it in ArcCatalog (Button "Neu berechnen" in the picture above), but how to reach the functionality programatically?

Thanks for any hint!

Grüß Dich,

Have you looked into a Python option? This link explains an approach using ArcPy to do what you are looking for.

Shaun-

thanks for the hint, but I couldn't find ArcPy functions, that will do the desired work.

I suppose, the task is "too specific", it depends on the given DBMS.

I still hope, someone has an idea...

Sorry for the bad link. Here is the correct link. Or you can search on Rebuild Indexes under Data Management.

Are you trying to Recalculate the Spatial Index or the Extent of that feature class?

I try to recalculate both. First I rebuild the spatial index but after that the feature class extend is equal to the extent of the feature dataset.

After creating the spatial index I have to recalculate the extent of the feature class (Button "Neu berechnen").
