Hi,
This code compiles happily for Win32, but refuses to compile for Win64:
====
program test;
{$mode objfpc}
{$h+}
uses
Registry;
type
TA = class
private
FRootKey: HKey;
public
//Win64/X86_64 Error: Range check error while evaluating constants
(18446744071562067969 must be between -2147483648 and 4294967295)
property RootKey: HKey read FRootKey write FRootKey default
HKEY_CURRENT_USER; //-2147483647
end;
begin
end.
===
Is this "by design" or is it a bug?
On Windows HKEY_CURRENT_USER is defined as HKEY(longint($80000001));
HKey is defined as HANDLE = System.THandle = QWord on 64-bit, but it
is DWord on 32-bit.
So infact the value of HKEY_CURRENT_USER would be 2147483649 (as a
DWord) on 32-bit, and 18446744071562067969 (as a QWord) on 64-bit?
Shouldn't HKEY_CURRENT_USER et al. be defined as HKEY(DWORD(somevalue)) instead?
Tested with fpc 3.2.2 and fpc main 3.3.1-2495-g6453af40d8
