Answer to Question #12559 in Visual Basic for Sophie

Question

what are the three-dimensions of an Array? and help me to create atleast 2 examples of an array program... thank you :)

Answer 1

Information:
Most multidimensional arrays that are used are two
dimensional arrays eg. databases with records and fields, screen coordinates
with X and Y and record sets with rows and columns, but there are greater
multidimensional arrays. There is very little documentation on these arrays.
Three dimensional arrays are basically multiple two dimensional arrays layered
on top of each other.Three dimensional arrays have many uses eg. mapping 3d
graphics, calendars (where days are the columns, the weeks are the rows and the
months are the layers), or paging methods for reports and record sets (as in the
example I provided below).


Example:
Private Sub
Combo1_Click()
'Clear the form
Me.Cls
'Set page selected
Page =
Combo1.Text
'Print the array info on the form
For Row = 1 To
UBound(Array3D, 2)
For Col = 1 To UBound(Array3D, 1)
Me.Print Array3D(Col,
Row, Page)
Next
Next
End Sub

Private Sub Form_Load()
'This
dimensions a three element array
ReDim Array3D(1, 10, 3)
'This loads data
into each element of the array starting with the
'third and nesting to the
first
For Page = 1 To UBound(Array3D, 3)
For Row = 1 To UBound(Array3D,
2)
For Col = 1 To UBound(Array3D, 1)
Array3D(Col, Row, Page) = Page &
"-" & Row
Next
Next
'This will add each page number to the combo
box
Combo1.AddItem Page
Next
'This will initially display the first
page
Combo1.ListIndex = 0
End Sub
