IGpDispatch Interface

Provides access to the properties and methods of a Geoprocessor object.

When To Use

The GPDispatch object is a coarse grainded ArcObject that permits geoprocessing tools and environments to be used in a scripting language. This object supports the COM IDispatch object. This object may also be used in COM-compliant languages such as Visual Basic for Applications (VBA), and Visual Basic. With ArcGIS 9.2, you are now recommended to use the new Geoprocessor class.
