Returns the highest index value used in the specified dimension of the VBArray.

The ubound method syntax has these parts:

Part Description
safeArray Required. A VBArray object.
dimension Optional. The dimension of the VBArray for which the higher bound index is wanted. If omitted, ubound behaves as if a 1 was passed.
If the VBArray is empty, the ubound method returns undefined. If dim is greater than the number of dimensions in the VBArray, or is negative, the method generates a "Subscript out of range" error.
