How can i describe buttons in matrix? - vb.net

Question

I have a 16*16 matrix and I'm trying to define them as a matrix series in vb.net. Then i make some visual shows with this matrix like led shows.
Dim n As Integer = 16
Dim l As Integer = 16
Dim x(n - 1, l - 1) As Integer
Dim i, j, k As Integer
For i = 0 To n - 1
For j = 0 To l - 1
For k = 1 To 256
If j= k mod16 then
buton(k) = x(i, j)
end if
Next
Next

I try to apply an algorithm. But it doesn't work. How can i accomplish this? Thanks for your interests..

OK I wrote something like this a while ago - I've adapted it to your needs and it runs ok on my pc. You need to create you array X like this
Dim x(15,15) As Button
To fill the array with buttons, use this method..
Private Sub InitializeArray()
Dim btnslist As New List(Of Button)
Dim btnNum As Integer
Dim btnName As String
Dim splitButtonName() As String
'add all the buttons to a list
For Each btnControl As Object In Controls
Dim btn As Button
'get button number and add it to the list if it is >0 and <=256
If TypeOf btnControl Is Button Then
btn = CType(btnControl, Button)
'get the button number
splitButtonName = Split(btn.Name, "n")
If CInt(splitButtonName(1)) > 0 And CInt(splitButtonName(1)) <= 256 Then
btnslist.Add(btn)
End If
End If
Next
'add the buttons to the matrix in the right order
For i As Integer = 0 To 15
For j As Integer = 0 To 15
For k As Integer = 0 To 255
btnNum = i * 16 + j + 1
btnName = "Button" & btnNum.ToString
If btnslist(k).Name = btnName Then
x(i, j) = btnslist(k)
Exit For
End If
Next
Next
Next
End Sub
