// This method draws a focus rectangle on Button2 using the 
// handle and client rectangle of Button2.
void Button1_Click( System::Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
   ControlPaint::DrawFocusRectangle( Graphics::FromHwnd( Button2->Handle ), Button2->ClientRectangle );
}

// This method draws a focus rectangle on Button2 using the 
// handle and client rectangle of Button2.
private void Button1_Click(System.Object sender, System.EventArgs e)
{
    ControlPaint.DrawFocusRectangle(Graphics.FromHwnd(Button2.Handle), 
        Button2.ClientRectangle);
}

' This method draws a focus rectangle on Button2 using the 
' handle and client rectangle of Button2.
Private Sub Button1_Click(ByVal sender As System.Object, _
