Button Array controls

[jungle38]

Hi Guys. This is my first question regarding programming in a long time.

See below a program that creates a form with a button array. The question
is simple. After the AddHandler MessageBox.Show is executed, how do I
refer to the button that was pressed, in order to change its color?

I've spent a lot of time looking for this. Just got back into programming after many years!

Thanks to all.

Public btn_array(5, 5) As Button
 
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 
        For i As Integer = 0 To 5
            For j As Integer = 0 To 5
                btn_array(i, j) = New Button
                Me.Controls.Add(btn_array(i, j))
                btn_array(i, j).Location = New Point(10 + i * 75, 10 + j * 30)
                btn_array(i, j).Text = "Button(" & i & "," & j & ")"
                btn_array(i, j).Name = "Button(" & i & "," & j & ")"
                AddHandler btn_array(i, j).Click, AddressOf MyControl_Click
            Next
        Next
 
    End Sub
 
    Private Sub MyControl_Click(ByVal sender As Object, ByVal e As EventArgs)
        MessageBox.Show("You have clicked control name " + sender.name)
    End Sub
 
End Class

You must first cast the sender (an Object type) to a Button type (it is in object form because all classes derive from Object)

dim testButton as Button = TryCast(sender, Button)
MessageBox.Show("You clicked button: " & testButton.name)
testButton.BackColor = Color.ColorValue
