Right, DWORD is a 32-bit entity in both Win32 and Win64. > So, why there are a lot of ULONG_PTR instead of DWORD if it is not to be > ported in Win64 ? That's there exactly for that purpose - to be portable to Win64. That's a variable that can potentially hold a pointer or a handle value. Win64 is not binary compatible with Win32, but is aimed to be source compatible. Read some docs about porting to Win64 for further details. -- Dmitry.
