Peter, longint is simply wrong. whist is may work in most circumstances, if you are on a system with a lot of handles being allocated, you will get to the realms on 32bit unsigned values. As the normal test for a handle allocation is : h := AllocateSomeHandle; if (h > 0) then Success else Recover; you are simply asking for trouble. A negative handle value is not acceptable. I'm guessing the problems have been got around by the shear luck of a silent cast when passing an longint to a function expecting a longword. However it's possible that L D Blake has stumbled accross somewhere where this is not possible. It's not actually a Cardinal, it's a DWORD that is the normal Win32 type. DWORD is mapped to LongWord in Delphi and therefore Cardinal.
