Glass *only* fallback, in Windows.Forms (when aero disabled / in XP)

Usage: Create windows.forms application and take stuff from here:

WPF Window with aero glass background. (C# .NET)

Usage, in your Window constructor do:

 ...
public partial class Window1 : Window
{
  public Window1()
  {
      InitializeComponent();
      this.GlassBackground();
  }
}
...

Installation:
1.) Add reference "System.Drawing" to your Project (Right click on References folder on your project, and Add reference)

2.) Add to your project a class file (GlassExtensions.cs) replace the "YOURNAMESPACE" in with same namespace as in your Window1.xaml.cs, and paste this:

using System;
using System.Drawing;
using System.Windows;
using System.Windows.Media;
using System.Runtime.InteropServices;
using System.Windows.Interop;

namespace YOURNAMESPACE
{
public static class GlassingExtension
{
    /// <summary>
    /// Sets glass background to whole window.
    /// </summary>
    /// <remarks>Remember to set your WPF Window Background to "Transparent"!</remarks>
    /// <param name="win"></param>
    public static void GlassBackground(this Window win)
    {
        // Glass extend WINAPI thingie http://msdn.microsoft.com/en-us/library/aa969512%28VS.85%29.aspx form more details
        // If any of the margins is "-1" the whole window is glass!
        win.GlassBackground(-1, 0, 0, 0);
    }
    /// <summary>
    /// Sets glass background to custom margins in the window.
    /// </summary>
    /// <param name="win"></param>
    public static void GlassBackground(this Window win, int left, int right, int top, int bottom)
    {
        // Why would you read the inner workings? Why? If you need to know why...
        // DwmExtendFrameIntoClientArea http://msdn.microsoft.com/en-us/library/aa969512%28VS.85%29.aspx is the magical WINAPI call
        // rest is just crap to get its parameters populated.
        win.Loaded += delegate(object sender, RoutedEventArgs e)
        {
            try
            {
                // Obtain the window handle for WPF application
                IntPtr mainWindowPtr = new WindowInteropHelper(win).Handle;
                HwndSource mainWindowSrc = HwndSource.FromHwnd(mainWindowPtr);

                // Transparent shall be glassed!
                mainWindowSrc.CompositionTarget.BackgroundColor = System.Windows.Media.Colors.Transparent;

                // Margin for the DwmExtendFrameIntoClientArea WINAPI call.
                NonClientRegionAPI.MARGINS margins = new NonClientRegionAPI.MARGINS();
                margins.cxLeftWidth = left;
                margins.cxRightWidth = right;
                margins.cyBottomHeight = bottom;
                margins.cyTopHeight = top;

                // Glass extend WINAPI thingie http://msdn.microsoft.com/en-us/library/aa969512%28VS.85%29.aspx form more details
                int hr = NonClientRegionAPI.DwmExtendFrameIntoClientArea(mainWindowSrc.Handle, ref margins);
                if (hr < 0)
                {
                    //DwmExtendFrameIntoClientArea Failed
