Looping through Controls in VB.NET

Question

I am creating a chess program. And it is composed of sixty four picture boxes with alternating black and white background colours.
I have named them pba1,

Answer 1

Put all the pictureboxes in an 8x8 tableLayoutPanel (also useful for scaling etc). Then

    For Each pb As PictureBox In TableLayoutPanel1.Controls
        Dim col As Integer = TableLayoutPanel1.GetCellPosition(pb).Column
        Dim row As Integer = TableLayoutPanel1.GetCellPosition(pb).Row
        If col Mod 2 = 0 Xor row Mod 2 = 0 Then
            pb.BackColor = Color.Black
        Else
            pb.BackColor = Color.White
        End If
    Next

Of course you could also use an array of the squares if you have that available.

This will not affect the events (pba1.click etc).
