Re: How can is see what button is pressed in a button array

By comparing references,
VB.NET Syntax (Toggle Plain Text)
  1.   Dim btn As Button = CType(sender, Button)
  2.         Dim i As Integer
  3.         For i = 0 To bttonArray.Length - 1
  4.             If btn.Equals(bttonArray(i)) Then
  5.                'statements
  6.             End If
  7.         Next

EDIT:
variable name changed.
