PS: note that the icon you get by entering an icon group number (which is what that number is) might be different depending on the version of Windows you have. Eg: icon group number 10 from shell32.dll is the network disk on XP, but is the hourglass icon on Wind7 ....
You can find out the icon group number by viewing the icon library with almost any program which is capable of showing you the icon resources in files.
