EXCEL VBA TUTORIAL DYNAMIC TWO DIMENSIONAL ARRAY PLUS

The following declarations create an array with 7 elements, with index numbers 0 to 6 (note that in the first declaration, the default lower bound is 0): Dim weekDays(6) As String or Dim weekDays(0 To 6) As String. One-dimensional array is a list of items having a single row or a single column, example, Quarterly Sales of a company during the year (the single dimension will be the row or column of 4 quarters of the year for which sales figures will be given). UBound(myArraењ“, 3) - LBound(myArraењ“, 3) + 1 UBound(myArraењ“, 2) - LBound(myArraењ“, 2) + 1 UBound(myArraењ“, 1) - LBound(myArraењ“, 1) + 1 Three-Dimensional Array: Dim myArraењ“(15, 0 To 20, 100 To 500) As Long Dimension 1: One-Dimensional Array: Dim myArray2(-3 To 7) As String Lower Bound One-Dimensional Array: Dim myArray1(5) As String Determine: When using these functions for a multi-dimensional array, specify the dimension for which the Lower Bound or Upper Bound are to be determined. The LBOUND and UBOUND Functions determine the Lower Bound and Upper Bound respectively, for an array. The size of an array is the total number of elements which is determined by the product of its dimensions.

Note: The lower bound and upper bound of a dimension are integers the index or subscript along the dimension will be an integer between both or equal to either the array length along the dimension is equal to 'upper bound minus lower bound plus 1'.

Not entering Option Base 1 will mean index values of 0, 1 and 2. This will mean that respective index values of an array with 3 elements will be 1, 2 and 3. outside the sub procedure) and then index will start from 1. You can specify Option Base 1 in the Declarations section of the module (ie. If you do not mention the lower bound, it is determined by the Option Base setting for the module, which by default is 0. using Dim statement), it is necessary to provide the upper bound (which is the last or largest index number), while the lower bound (which is the first or smallest index number) is optional. The individual items in an array are referred to as elements and their respective index values (or subscript) would be 0, 1, 2, and so on.

VBA allows to refer them with the same name and treats them as a single variable. If you work with a list of items of similar data type, say 20 numbers, then instead of declaring each item as a separate variable, you can declare them as only one array of variables. Note that if the data type is Variant, each element may consist of a different type of data viz.
