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.

[CODE=vbnet]Public btn_array(5, 5) As Button

Private Sub Form1_Load(ByVa l sender As System.Object, ByVal e As System.EventArg s) 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[/CODE]

OS: Windows XP Home
Language : Visual Basic 2005

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

[CODE=vbnet]
dim testButton as Button = TryCast(sender, Button)
MessageBox.Show ("You clicked button: " & testButton.name )
testButton.Back Color = Color.ColorValu e
[/CODE]
