Rotate binary

[qwer85]

I have a binary:

0xDCF5E801

how to convert it, so I will get this:

0x01E8F5DC

I have done it by following script:

$tmp = BinaryToString($binary)
$new_binary = StringToBinary(StringMid($tmp, 4, 1) & StringMid($tmp, 3, 1) & StringMid($tmp, 2, 1) & StringMid($tmp, 1, 1))

is there any way to simplify this script?

Thanks.

I have a binary 0xDCF5E801 how to convert it, so I will get this 0x01E8F5DC.

Thanks.

Your question is analagous to the following:

I have 5,697,476. How do I make it -3?

Please elaborate on exactly you want done in order to make 0xDCF5E801 0x01E8F5DC.

pls look at the modified first post

The difference between those numbers is that each two bytes are grouped in "words" and there is a back order of those "words".

To change endian-ity of dwords I use this:

Func byteSwap($bin)
    Return Binary(BitRotate(String($bin), 32, "D"))
EndFunc

To change endian-ity of dwords I use this:

Func byteSwap($bin)
    Return Binary(BitRotate(String($bin), 32, "D"))
EndFunc

thx a lot, that helped me at once...

I'm trying to implement searching the value in memory by pointer, can someone explain me why this happens?

When i use foll script (with pointer search):

$v_Read = _MemRead($v_Open, 0x01D2AE53, 4)
$tmp = Binary(BitRotate(String($v_Read), 32, "D"))
ConsoleWrite($tmp & @CRLF)
$v_Read = _MemRead($v_Open, $tmp, 5)
ConsoleWrite($v_Read & @CRLF)oÝ÷ Ú(¶Øb²)Ü¢{(ç(uí1ÓQ

It gives me the right result:

0x01E8F5DC
0x616C696173

Well, looks like _MemRead function doesn't like Autoit's Binary data type as an argument.

Try Dec(Hex(Binary(BitRotate(String($v_Read), 32, "D")))).

Although TBH this conversion is turning from extravagant to ridiculous quite fast

Dec(Binary(BitRotate(String($v_Read), 32, "D"))) returns 0

don't skip that Hex()

[qwer85]

don't skip that Hex()

hoh, you are genious, man

thanks again.
