Loading Icons from Resource

Hi All.  This is a simple question.  I want to be able to load some of the icons from SHELL32.DLL (found in the Windows' System directory).  This is what I have so far:

var ResDLL: THandle;
    P: Array[0..250] of Char;
    S: String;
    H: HIcon;

begin
   GetWindowsDirectory(P, SizeOf(P));
   S := StrPas(P);
   S := S + '\SYSTEM\SHELL32.DLL';
   StrPCopy(P, S);
   ResDLL := LoadLibrary(P);
   If ResDLL = 0 then begin
     ShowMessage('Failed to load DLL');
     Exit;
   End;
   H := LoadIcon(ResDLL, MakeIntResource(64));
   Image1.Picture.Icon.Handle := H;
   FreeLibrary(ResDLL);

The problem is, H (HIcon) is returning 0.  Any reason this is happening?

Regards,

Stuart.
