Requirements: View

This example demonstrates how to use the Register Event Callback function with ActiveX automation refnums. This VI launches an instance of Internet Explorer and then registers callback VIs to respond to events fired by Internet Explorer.

Two events are registered. Whenever a new document finishes loading in the browser, the DocumentComplete event fires and HTML_Callback.vi executes. If the browser window closes, the OnQuit event fires and On_Quit_Callback.vi executes.
