How do you transfer these pointers and what are you trying to
accomplish? You generally cannot transfer pointers from one running
program to another. It may work by accident in some cases, but it is
not something you can rely on (even if both programs are compiled by
the same version of the same compiler on the same OS and are running
on the same machine).

I transfer them as numbers. I work under win32. I transfer them as
LParam-s with PostMessage() WinAPI function. Numbers are
transferred correctly (I checked it with .messagebox/writeln).
I try to have access to the same physical memory (I want to have
common read-write variable).
Each and every process has its own virtual memory space under win32
(and most other operating systems). You cannot access the same
physical memory this way (not in Delphi either), you must use some
Win32-specific functions to setup a shared memory area and request
the OS to map it in both processes. I don't know how to do this on
win32.

PS: in general always reply to the mailing list, unless people
explicitly ask not to do that._______________________________________________
