protected override void WndProc(ref Message m)
{
       // Listen for operating system messages.
       switch (m.Msg)
       {
              // The WM_ACTIVATEAPP message occurs when the application
              // becomes the active application or becomes inactive.
              case WM_ACTIVATEAPP:

              // The WParam value identifies what is occurring.
              appActive = (((int)m.WParam != 0));

              // Invalidate to get new text painted.
              this.Invalidate();

              break;
       }
       base.WndProc(ref m);
}
