C # implement Windows 7 Aero frosted glass using WinForm

After the Vista system, Microsoft provided the Aero matte effect for the form program, such. C # is used as an example.
How can we achieve this matte effect?

 

Code:

 System; System.Collections.Generic; System.ComponentModel; System.Data; System.Drawing; System.Text; System.Windows.Forms; System.Reflection; System.Runtime.InteropServices; WindowsFormsApplication1{     partial  Form1 : Form    {                [StructLayout(LayoutKind.Sequential)]          MARGINS        {              Left;              Right;              Top;              Bottom;        }                [DllImport("", PreserveSig = )]           DwmExtendFrameIntoClientArea(IntPtr hwnd,  MARGINS        margins);                [DllImport("", PreserveSig = )]           DwmIsCompositionEnabled();                   OnLoad(EventArgs e)        {             (DwmIsCompositionEnabled())            {                MARGINS margins =  MARGINS();                margins.Right = margins.Left = margins.Top = margins.Bottom =        .Width + .Height;                DwmExtendFrameIntoClientArea(.Handle,  margins);            }            .OnLoad(e);        }                   OnPaintBackground(PaintEventArgs e)        {            .OnPaintBackground(e);             (DwmIsCompositionEnabled())            {                e.Graphics.Clear(Color.Black);            }        }         Form1()        {            InitializeComponent();        }    }}

 

 

 

In this example, the system's dwmapi. dll is called.

Dwmapi. dll is a dynamic link library of the Microsoft Desktop Window Manager API (the common interface of the Desktop Window Manager DWM). It is a normal file and is mainly used as an api for Desktop effect.

 

DWM is a new interface that provides DWM interfaces in all Windows Vista versions except Windows Vista Home Basic. Therefore, this effect can only be used in systems after Vista.
