[fdo-internals] [fdo-users] Shape file Extents

[Dan Stoica]

As a reminder, the spatial context extents are dynamic in the SHP provider case.

Therefore you can get the extents by using GetSpatialContexts command.

Don, do you volunteer to write a snippet?

Thanks,
Dan.

That would be wonderful. I'm sure I can pull many useful snippets out of the
FDO Toolbox code that may be of great use.
