Example
The RegisterExternalWindow transaction registers a window handle from an external application for use by Imagenation. You can use it to render either a document, Reference, or Detail external window. The return value is used in other external window transactions.
After you register an external window as a document window, you can open a document in it, and perform actions on the document (such as Merge and Save). However, before opening another document in it, you must unregister the external window, and then register it again. If you open and process multiple documents in an external window without registering and unregistering the window each time, you will quickly run out of resources.
