Check that VirtualProtect succeeded?

Eh, seems it has ironed out itself. I guess I implemented VirtualProtect, compiled, but didnt move the dll into my system directory.

blarg.

You only protected 11 Bytes (0x0B), however, you write more than that.

You write to the beginning of the address 0x0040482E, but even if you write only 2 bytes the last byte will be written to 0x0040482F which is still protected, simply change the size (0x0B) to 0x0B + sizeof(code4).

If you would've debugged it, you would've seen that it throws the exception at the last memcpy call.

0x0040482E - 0x00404823 = 0xB?

Wouldn't that be the region size that i'm writing?

Edit: eh nevermind, it's 12 bytes, 0xC

my logic was jacked.
