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

This is fairly simple and it may be resource heavy, but it works. I have a form with 36 CheckBoxes. This takes advantage of the fact that when you copy a checkbox it just increases the number of the name. I ended up with 36 checkboxes named CheckBox1 thru Checkbox36. The Function returns a checkbox, which may be used to set or read any property.

Private Function GetCheckBox(ByVal Index As Integer) As CheckBox
    Dim CKBox As checkbox
    For Each cntrl As Control In Me.Controls
        If TypeOf cntrl Is CheckBox Then
            CKBox = cntrl
            If CKBox.Name = "CheckBox" & Index Then
                Exit For
            End If
        End If
    Next
    Return ckbox
End Function
