What syntax do you use to add decimal data held in a NumericUpDown control, and add it to a one dimensional array?
Is there a keyword to sum all the items in the array into one number(For averaging purposes)?

Dim heightarray As String()

        ReDim Preserve heightarray(0 To UBound(heightarray) + 1)
        heightarray(UBound(heightarray)) = heightNumericUpDown.Value

Using a List(Of T) will expose some great extension functions for you:

Dim heightList As New List(Of Double)

heightList.Add(heightNumericUpDown.Value)

heightList.Sum
heightList.Average
heightList.Min
heightList.Max

Interesting! So this List(of T) is a type of array then?

A type specific collection, but you can think of it as an array. It has more functionality though.

Well that is extremely helpful on a personal level! But this is for a class and the book isn't covering arrays the way id like it too. I tried a few sites for breakdowns but most of them just confused me. For this particular problem i NEED to use a one dimensional array. My main issue is Understanding the syntax.

What goes in the parenthesis? The number of arrays you intend to have? OR Is this the ID to access particular data in the initializer list?

What is a Initializer list? How can i add new elements from a Numeric Up Down?

Class level variables:

Private size_of_array As Integer = 0
Private heightarray As String() = {}

The code to add a new value:

'add new value - in a sub routine
Redim Preserve heightarray(size_of_array)
heightarray(size_of_array) = heightNumericUpDown.Value.ToString
size_of_array += 1

So i dont have to mess with the initializer list unless i wanna set predefined variables?

Oh so you assign arrays the same way i assign all other variables. What about summing the data inside of an array?

[_HAWK_]

For that you need a loop from 0 to the array.count -1 and convert the string to integer or double while adding them to a variable that will hold the total.

Thinking of a list, you were.

 
array.length -1

Once i got this all to work i understand how these work alot better now.
