ArcGIS Engine Developer Guide

BUILDING A COMMAND-LINE C++ APPLICATION
Any additional extension functionality must use
an extension license that matches the core
license being used at that time. If the application
initially accesses an ArcGIS Engine Runtime
license, it must use the 3D or Spatial extensions
for ArcGIS Engine if required. If the application
initially accesses an ArcGIS Desktop license
(ArcView, ArcEditor, or ArcInfo), it must use
ArcGIS 3D Analyst or ArcGIS Spatial Analyst
extension licenses if required.
This is a placeholder comment to indicate where
additional code will be placed later in the
exercise.
license being used, Engine or Desktop, either the Spatial extension for ArcGIS
Engine Runtime or an ArcGIS Spatial Analyst extension must also be available.
Your application must confirm the availability of, then check out, the necessary
licenses as required.
4. In RasterSlope.cpp’s main(), initialize ArcGIS Engine and set up the licensing
for the product. Next, shut down and uninitialize ArcGIS Engine. These lines
of code can be placed after the command-line arguments have been processed;
that part of the application does not need access to ArcGIS Engine and, if the
arguments are invalid, there is no reason to start ArcGIS Engine.
