Programming Tips & Gotchas
Due to the nature of variants, it isn’t always obvious if a
variant variable contains an array, especially if you pass the
variant to a function, and the function may or may not attach an
array to the variant. Calling any of the array functions, such as
LBound
or UBound
, or trying
to access an element in an array that doesn’t exist will
obviously generate an error. In these situations, you should first
use the IsArray
function to determine whether
you can safely process the array.
