In VLF-WIN the Framework services manager allows command handlers or filters to retrieve the reference to a VLF icon.
If using a reference to an icon multiple times, it is better to use the avFindIcon method once in the initialization routine, and store the reference in a dynamic variable defined at the component level. (See example)
The reference to a VF_ icon is retrieved using the avFindIcon method.
