Creating C# Glass Form

I’ll show you how to convert your forms background to glass. Glass effect is only for Windows 7 and Vista. Glass Effect wont work with Windows XP. First, we’ll call the required DLL’s.

[System.Runtime.InteropServices.DllImport("dwmapi.dll", PreserveSig = false)]
       public static extern bool DwmIsCompositionEnabled();

[System.Runtime.InteropServices.DllImport("DwmApi.dll")]
       public static extern int DwmExtendFrameIntoClientArea(
           IntPtr hwnd,
           ref MARGINS pMarInset);

Then we'll write the method that determines the usage of glass effect on our form.

[System.Runtime.InteropServices.StructLayout(System.Runtime.InteropServices.LayoutKind.Sequential)]
       public struct MARGINS
       {
           public int cxLeftWidth;
           public int cxRightWidth;
           public int cyTopHeight;
           public int cybottomHeight;
       };

After that we'll write a method

void glassform()
       {
          
           MARGINS margins = new MARGINS();
           margins.cxLeftWidth = -1;  //-1 means all the form
           margins.cxRightWidth = -1;
           margins.cyTopHeight = -1;
           margins.cyBottomHeight = -1;
          
               if (DwmIsCompositionEnabled() == true)
               {
                   IntPtr hWnd = this.Handle;
                   int result = DwmExtendFrameIntoClientArea(hWnd, ref margins);
               }
               else
               {
                   this.BackColor = System.Drawing.Color.White;
               }
          

       }

And last we’ll call the glassform method from form_load

here’s the result
