Protecting memory ?

[Cuervo]

Is there a way to protect memory to keep from being written.

I look at GlobalMemoryLock but doesn't preform this fucntion.

Is there no way to lock an offset in memory to keep a program from changing a byte??

Processes normally just get the "virtualized or idealised view" of the RAM as one, empty, continuous block of memory. What you like to access is the physical memory addresses and requires at least Administrative rights and probably should be better implemented at driver level.

Now that I think about it, I guess most programs would crash if they failed to write to memory, I guess.

So, then, how does a program like cheat engine feeze an offset? I'm hoping that can be accomplished with Autoit as well.

Cheat Engine freezes by constantly writing the value every x milliseconds (defined in options).

Ah, I see that now. Kind of strange really because I can run a trainer and exit it but the offset still keeps the same value.
