I don't know C#, but I'll give it a go in explanation.

Code: [Select]

char*[] p = 09C97AF2; //The nickname will be an array of chars, so we set a pointer to that address

p* = "New Nickname"; //Assign the new data to the pointer



And that *should* work, but I don't know C#, only C/C++. :P

Late last night, Quebec was invaded by a group calling themselves, "Omnimaga". Not much is known about these mysterious people except that they all carried calculators of some kind and they all seemed to converge on one house in particular. Experts estimate that the combined power of their fabled calculators is greater than all the worlds super computers put together. The group seems to be holding out in the home of a certain DJ_O, who the Omnimagians claim to be their founder. Such power has put the world at a standstill with everyone waiting to see what the Omnimagians will do...

Wait... This just in, the Omnimagians have sent the UN a list of demands that must be met or else the world will be "submitted to the wrath of Netham45's Lobster Army". Such demands include >9001 crates of peanuts, sacrificial blue lobsters, and a wide assortment of cherry flavored items. With such computing power stored in the hands of such people, we can only hope these demands are met.

In the wake of these events, we can only ask, Why? Why do these people make these demands, what caused them to gather, and what are their future plans...

A string is nothing more than an array of chars, at least in C++. No reason it's not the same for C#

Just to note, I believe I've heard it somewhere that each program has it's own memory space for pointers, so an address in one program wouldn't equal the address in another. So you might not be able to easily access the memory of an external program like that. But, then again I'm not 100% sure.

If it's in cheat engine, you should be able to modify the string through that.

You cant use pointers in C#.
A pointer is only in existance as long as the program is running, what are you trying to do?

Also HOMER-16 is correct, almost all os's use something called virtual memory, so that address is actualy not the physical address.

I believe he is trying to write a program that will change his MW3 nickname. He's trying to read/write to the address that contains it.

You can indeed use pointers like in C, but you have to use an unsafe block.

C# is not a language in the same family as C/C++. It's much closer to Java than any compiled language. The name is just confusing in that respect.

As for whether you can use pointers, generally you can. The most common form of "pointer" in C# is what's called a "reference." It's basically meaningless obfuscation to call it that, but you can think of them as effectively pointers with some associated metadata for the interpreter.

@Homer, you should NEVER be accessing another program's memory space, so virtual memory isn't an issue. Besides, physical pointers in modern computers are far more complex to deal with than virtual pointers. Either way, use the interface the other code exposes. It is the best way to interact with other code.

I think i first had to get the adress of the external prog, for mw3 that would be looking for the adress for "iw5", google it and i find the method, but i don't get how to write/read it's pointers then, just adresses work, but pointers are a lot more difficult, as for changing it with cheatengine, that works, but i want it to be a feature in my hack, there are(/were) namechangers before...

Sorry for double post

But does someone know if it's possible to use a little part of c/++ code in c#?

Cause that would be much easyer for pointers
