IGCoreCtl

The central object on which everything else depends is IGCoreCtl Control. You'll place one of these into the user interface of your application, and then use it to control the processing of all the other objects. IGCoreCtl Control is an ActiveX control, which allows you to use it in the UI designer tool of each development environment. However, IGCoreCtl Control presents no user interface to the application end-user at run-time - it is visible only at design-time.
