FailedDisplayURL Event
This event executes whenever the DisplayURL (page 62) property is
changed and the file to which it refers is invalid. This event has no
parameters; however, the host application can always get the current value
of the DisplayURL property. It can also respond to this event by setting the
property to a new URL.
Example
The following sample HTML script demonstrates how the
FailedDisplayURL and FailedServerIniURL (page 75) events can be
used to correct invalid references. When the page is loaded, the Display
URL refers to a file named fee.pdi and an ini file of eenie.ini. If
either of the URLs is invalid, then three additional display and
server.ini URLs are tried. The two URLs are always set in tandem.
