Private Sub button1_Click(sender As Object, e As EventArgs)
    ' If myVar is an even number, click Button2.
    If myVar Mod 2 = 0 Then
        button2.PerformClick()
        ' Display the status of Button2's Click event.
        MessageBox.Show("button2 was clicked ")
    Else
        ' Display the status of Button2's Click event.
        MessageBox.Show("button2 was NOT clicked")
    End If
    ' Increment myVar.   
    myVar = myVar + 1
End Sub 'button1_Click
C#
private void button1_Click (Object sender,
