CObArray::GetUpperBound

Returns the current upper bound of this array.

INT_PTR GetUpperBound( ) const;

Return Value

The index of the upper bound (zero-based).

Remarks

Because array indexes are zero-based, this function returns a value 1 less than GetSize.

The condition GetUpperBound( ) = –1 indicates that the array contains no elements.
