IsAutoRefresh is a vba function that takes 1argument and must be called as: IsAutoRefresh( yes )
It returns TRUE on success and FALSE on failure.
This function effectively returns information on whether Excel is in auto-refresh mode, but this currently has no value as the latter feature is not yet implemented.
It does so by means of the argument yes, which must be supplied as a variable of type Boolean in order to be set by the function to TRUE when Excel is in auto-refresh mode and FALSE otherwise.
