Does anyone know how to get the icon used for a given file type? For e.g.,
if I have a box containing all the files in a directory, I would like Word
files to have the Word icon, mp3 files to have their default icon, etc. etc.

Thanks,

Here's a class that does the job (not my own work, save for a few
modifications, but pulled from a posting in the MS groups).  General usage
is:

Icon myicon = ExtractIcon.GetIcon(mypath, true, false);

...but see comments in the code below.

Hope it helps.

Rob.

 public class ExtractIcon
 {
  [DllImport("Shell32.dll")]
  private static extern int  SHGetFileInfo
   (
   string pszPath,
   uint dwFileAttributes,
   out SHFILEINFO psfi,
   uint cbfileInfo,
   SHGFI uFlags
   );

  [StructLayout(LayoutKind.Sequential)]
   private struct SHFILEINFO
  {
   public SHFILEINFO(bool b)
   {
    hIcon=IntPtr.Zero;iIcon=0;dwAttributes=0;szDisplayName="";szTypeName="";
   }
   public IntPtr hIcon;
   public int iIcon;
   public uint dwAttributes;
   [MarshalAs(UnmanagedType.LPStr, SizeConst=260)]
   public string szDisplayName;
   [MarshalAs(UnmanagedType.LPStr, SizeConst=80)]
   public string szTypeName;
  };

  private ExtractIcon()
  {
  }

  private enum SHGFI
  {
   SmallIcon   = 0x00000001,
   OpenIcon   = 0x00000002,
   LargeIcon   = 0x00000000,
   Icon    = 0x00000100,
   DisplayName   = 0x00000200,
   Typename   = 0x00000400,
   SysIconIndex  = 0x00004000,
   LinkOverlay = 0x00008000,
   UseFileAttributes = 0x00000010
  }

  /// <summary>
  /// Get the associated Icon for a file or application, this method always

  /// <returns></returns>
  public static Icon GetIcon(string strPath, bool bSmall, bool bOpen)
  {
   SHFILEINFO info = new SHFILEINFO(true);
   int cbFileInfo = Marshal.SizeOf(info);
   SHGFI flags;
   if (bSmall)
    flags = SHGFI.Icon|SHGFI.SmallIcon;
   else
    flags = SHGFI.Icon|SHGFI.LargeIcon;
   if (bOpen) flags = flags|SHGFI.OpenIcon;

   SHGetFileInfo(strPath, 256, out info,(uint)cbFileInfo, flags);
   return Icon.FromHandle(info.hIcon);
  }
 }//end class

That did the trick very nicely, thanks a lot :)
