How to convert a QWORD entry from a REG file in the @regread() format:

%s =@regread(HCU,Control Panel\Appearance\New Schemes\0\Sizes\0,Size #5)

returns 15

In the REG file we have:

"Size #5"=hex(b):0f,00,00,00,00,00,00,00

Code:

%a ="0f,00,00,00,00,00,00,00"
# Remove ,
%a =@strrep(%a,",",,EXACT,ALL)
# Reverse
%a =@substr(%a,15,16)@substr(%a,13,14)@substr(%a,11,12)@substr(%a,9,10)@substr(%a,7,8)@substr(%a,5,6)@substr(%a,3,4)@substr(%a,1,2)
# HEX to DEC
%a =@sum($%a)


%a =15 now...

In the reg it should read "0x0000000f"

I forget why its "Size #5"=hex(b):0f,00,00,00,00,00,00,00 in an exported reg file.

the decimal equivalent is "15"

Code:
%a = @hex(15,8)
%b = @sum($%a)
info %a@cr()%b
exit


What exactly are you looking for or trying to do???

It has to do with endianness. Windows is Little-Endian however we (humanoid life forms) read values in big endian. Here is a link to MSDN for registry data types http://msdn.microsoft.com/en-us/library/bb773476%28VS.85%29.aspx
