In order to create IGPageDisplay Object objects, your application usually needs an IGDisplayCtl Control control. Like IGCoreCtl Control, IGDisplayCtl Control is an ActiveX control, which allows you to use it in the UI designer tool of each development environment. Like IGCoreCtl Control, IGDisplayCtl Control presents no user interface to the application end-user at run-time - it is visible only at design-time. Your application program must associate the IGDisplayCtl Control with the IGCoreCtl Control before using it - this is typically done when your application first starts up. Once your application has done this, then it can use the IGDisplayCtl Control to create as many IGPageDisplay Object objects as needed.
