  You could also have a look at the new method for .NET 2.0 called Icon.ExtractAssociatedIcon, however this won't retrieve icons for folders.

  Try to explain again what you are tring to do

  I think I understand now, you want to find what is the icon of a file, like for msword.exe, you want to get the Word Icon

  if so, check out my articale:

  http://www.codeproject.com/cs/miscctrl/FilesListBox.asp

  and look at the IconExtractor util class.

  Ok,so this is the link you need:

  http://www.codeproject.com/cs/miscctrl/FilesListBox.asp

  This is the class you need:

  /// <summary>

  /// Util class to extract icons from files or directories.

  /// </summary>

  class IconExtractor

  {

  [StructLayout(LayoutKind.Sequential)]

  public struct SHFILEINFO

  {

  public IntPtr hIcon;

  public IntPtr iIcon;

  public uint dwAttributes;

  [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 260)]

  public string szDisplayName;

  [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 80)]

  public string szTypeName;

  };

  class Win32

  {

  public const uint SHGFI_ICON = 0x100;

  public const uint SHGFI_LARGEICON = 0x0; // 'Large icon

  public const uint SHGFI_SMALLICON = 0x1; // 'Small icon

  [DllImport("shell32.dll")]

  public static extern IntPtr SHGetFileInfo(string pszPath,

  uint dwFileAttributes,

  ref SHFILEINFO psfi,

  uint cbSizeFileInfo,

  uint uFlags);

  }

  /// <summary>

  /// Gets the icon asotiated with the filename.

  /// </summary>

  /// <param name="fileName"></param>

  /// <returns></returns>

  public static Icon GetFileIcon(string fileName, IconSize _iconSize)

  {

  System.Drawing.Icon myIcon = null;

  try

  {

  IntPtr hImgSmall; //the handle to the system image list

  SHFILEINFO shinfo = new SHFILEINFO();

  //Use this to get the small Icon

  hImgSmall = Win32.SHGetFileInfo(fileName, 0, ref shinfo,

  (uint)Marshal.SizeOf(shinfo),

  Win32.SHGFI_ICON |

  (_iconSize == IconSize.Small Win32.SHGFI_SMALLICON : Win32.SHGFI_LARGEICON) );

  //The icon is returned in the hIcon member of the shinfo

  //struct

  myIcon =

  System.Drawing.Icon.FromHandle(shinfo.hIcon);

  }

  catch

  {

  return null;

  }

  return myIcon;

  }

  }

  /// <summary>

  /// Specifies the icon size (16 or 32)

  /// </summary>

  public enum IconSize

  {

  /// <summary>

  /// 16X16 icon

  /// </summary>

  Small,

  /// <summary>

  /// 32X32 icon

  /// </summary>

  Large

  }

  Call :

  Icon fileIcon = IconExtractor.GetFileIcon(fullFileName, _IconSize.Small);

  Yes David you are right, but yet, it have very limited access comparing to the native windows api, not only for folders but also for some file types.
