Hey,

I have a CE script I'd like to add to my C++ application, but I have encountered a small problem.

In the script I have this, which works perfectly.
Code:

alloc(val, 8)
registersymbol(val)
...
hook:
mov [val], eax
...


But in my C++ source I have tried doing this, which works with values under 4294967295, but overflows when above that.

Code:

unsigned __int64 val;

__asm
{
   mov dword ptr[val], eax
}


Removing/replacing "dword ptr" (which makes it 4 bytes, I know) throws me an "error C2443: operand size conflict", which I have tried digging around on google for.

Is there any way to read the "missing" 4 bytes? Some smart ror/rol thing that I don't know of?

What missing four bytes?

EAX can only store 4 bytes total, so your 8 bytes variable will always have 4 "empty" bytes (which are zero).

So either use "rax" here or an unsigned int32 (not int64).

Your variable should be
Code:
unsigned __int32 val;
