Any better alternative to writeBytes for 4 bytes variables?

Greetings.

I'm currently using writeBytes to set values for 4 bytes variables.

As an example, I would use
Code:
writeBytes("20123456", 78, 97, 188, 0)

To set value 00BC614E to variable 20123456.

This requires, however, manual value conversions. Is there no direct way to set the HEX value? Or any other better alternative.

Regards,
Lalz.

Code:

writeInteger('theAddress', 0x123ABC)
writeInteger('theAddress', tonumber('123ABC', 16))

Even though CE doesn't complain about the code not being injectable, neither seems to work. Are you sure your code isn't wrong?

UPDATE: "tonumber" function is working but "writeInteger" isn't. That reminds me, Isn't integer just up to 2 bytes? Because we're trying to write 4 here.

writeInteger (and other similar functions) will only work when memory is writable.

writeBytes is the only one which uses VirtualProtectEx to change flags.


So, you have few options:

1
fullAccess('theAddress', 4)
writeInteger('theAddress', 0x00BC614E)


2
autoAssemble('theAddress:\ndd 00BC614E')

Only the latter works, but that's already an improvement. No idea why the former won't.
