Integer is 4 bytes on both 32 and 64 bits. Int64 is 8 bytes on both. NativeInt/NativeUInt is 4 bytes on 32 and 8 bytes on 64. WPARAM and LPARAM message types are defined as NativeInt so you can cast a pointer to them.

No, Integer remains 4 Byte in x64. But Using NativeInt should work on both 32 and 64 bit.

Integer will _not change of course. Just noticed that even my Delphi 2006 supports NativeInt. Will use it for pointer/handle casting related code whenever I stumble over it now.

No, have a look here : http://en.wikipedia.org/wiki/64-bit Topic "64-bit data models" In Windows and Unix-like systems an int remains 32-bit.

I guess asm blocks could be adopted to x64 too. Emb-ro advices to reject asm at all though. I examined the ICS units some time ago and found only several places that *may* require changing. But maybe WinSock wrappers would require it as Windows' types lika UINT, LRESULT etc are used quite rarely, most coders use general integer types instead.

Most people are aware that Embarcadero does not allow it's beta testers to identify themselves except under limited circumstances, nor talk about beta products.

Re: [twsocket] [OT] 64-bit Delphi preview
Given Embarcadero's total distain for "the little folk", I hope ICS will continue to leave versions of the ICS which are compatible with Delphi 4 and Delphi 7 on the ICS website, for those of us still doing productive work on the "early" Delphis which can... shock horror!... still be installed on systems simply by entering a registration key, rather than via an online registration process which leaves the package owner vulnerable to the marketing choices of the software producer. As Kylix seems "dead", I hope Lazarus is thriving, and that a version of ICS which works with that is/ will remain available... but will understand that if Lazarus is NOT doing well, the energy to support it cannot be justified.

Re: [twsocket] [OT] 64-bit Delphi preview
I agree, it would be great if ICS could be used from Lazarus.

The latest ICS V6 and V7 are still fully compatible with Delphi 7 and
2007, and will remain so, since Arno uses the former and I the latter
(and have some old D7 projects). Few people want to update major old
projects to Unicode so support for these is essential for years to come.
Earlier Delphi releases are more problematic, since Borland was still
adding language features like int64, 64-bit streams and dynamic arrays.
ICS V5 still supports Delphi 6 and earlier, but only gets bug fixes for
serious issues.
> As Kylix seems "dead", I hope Lazarus is thriving
The Embarcadero roadmap for future releases shows:
- Delphi 64 bit
- Mac OSX support
- Server Linux support
- GUI linux support
and if you look in the source code for the Delphi XE libraries, you will
find a lot of conditional code such as:
{$IFDEF LINUX}
ExeBaseAddress = Pointer($8048000) platform;
{$ENDIF}
{$IFDEF MACOS}
ExeBaseAddress = Pointer($1) platform;
{$ENDIF}
{$IF defined(CPUX64)}
FSSegBase: Pointer = nil;
{$IFEND}
{$IFDEF POSIX}
procedure _GetCallerEIP;
{$ENDIF POSIX}
so I think you can assume that a lot of work has already been done on
these implementations by Embarcadero.
The main issue with Linux/Mac is the same as Kylix, which is no windows
events and no VCL, which makes supporting these from the same ICS code
base as Windows very difficult.

Well, if they don't they will lose customers sooner or later, not just due to missing Unicode but also 64-bit that will be the standard very soon.
