SetAlternateInterface(), SetLibrary()

Sets the name of the alternate User Interface (UI) database.

SetAlternateInterface(string ui_db_name)

Argument	Contents
ui_db_name	The full path and filename of the alternate UI database, or null to clear an alternate UI database

The alternate UI database is searched for macros and dialog boxes before the current UI database.
There can be only one alternate UI database at a time, though repeated calls to SetAlternateInterface() will create a stack of alternate UI databases. If you set one alternate UI database and then set another, call SetAlternateInterface(null) to restore the previous alternate UI database as the current one.
Can also be called as SetLibrary().

SetAlternateInterface("geocode")

// Do some geocoding, then clear the Geocode UI from the stack

SetAlternateInterface(null)

Error Type	Meaning
Error	The UI database cannot be opened
