This site is for ArcGIS 9.2 and prior

Updated Aug 11, 2010

IMPORTANT: As of the ArcGIS version 9.3 release in July 2008, you now have access to developer SDKs, documentation, samples, communities, and other helpful resources through the ESRI Resource Centers. Developer resources for ArcGIS versions 9.2 and prior will, for the time being, still be accessible through this legacy EDN site. Changes to these Web sites and their resources have no effect on the EDN product, software subscription, or add-on products.
